The Psychological Sign Of Omega-3 Deficiency

Omega-3 fatty acids are essential as our body cannot make them.

Omega-3 fatty acids are essential as our body cannot make them.

Feeling depressed can be a sign of a poor diet, research suggests.

Indeed, healthy diets are often overlooked as a major factor in recovering from depression.

An important component of a healthy diet is omega-3 fatty acids.

Studies have found that omega-3 supplements can be beneficial for people with depression.

Omega-3 fatty acids are essential as our body cannot make them.

Omega-3 can be obtained from the diet or through supplementation.

Foods high in omega-3 fatty acids include walnuts, chia seeds, soybean, hemp seed, salmon, trout, sardines, and mackerel.

While the standard treatment for depression is antidepressants, many people discontinue them for fear over the side-effects and start using alternative treatments.

Dr. François Lespérance, who has studied the effects of omega-3 on depression, said:

“Despite significant progress in neuroscience over the past two decades, depression is difficult to treat.

Many of these treatments have not been adequately evaluated.

That is why it was important to assess the efficacy of Omega-3, one of the most popular alternative approaches.”

The study included 432 people with depression.

Half took 1050mg of EPA each day for eight weeks.

Eicosapentaenoic acid (EPA) is one of the three main omega-3 fatty acids.

The other group took a placebo that was flavoured with fish oil so they would not know the difference.

The results showed that for people who were depressed, but not anxious, the omega-3 fatty acid was effective at reducing depression.

The study’s authors conclude:

“In this heterogeneous sample of patients with MDE, there was only a trend toward superiority of omega-3 supplementation over placebo in reducing depressive symptoms.

However, there was a clear benefit of omega-3 supplementation among patients with MDE without comorbid anxiety disorders.”

The study was published in the Journal of Clinical Psychiatry (Lespérance et al., 2011).

One Sign Of Vitamin B12 Deficiency Is Mental

Vitamin B12 deficiency is easy to correct for most people.

Vitamin B12 deficiency is easy to correct for most people.

Memory and thinking problems can be a sign of vitamin B12 deficiency, research finds.

People with low vitamin B12 can find it harder to sustain attention, learn words and names and solve puzzles.

Low levels of the vital vitamin have also been linked by research to brain shrinkage.

Vitamin B12, along with folate, help to protect the cognitive function of older people.

Good sources of vitamin B12 include fish, poultry, eggs and low-fat milk.

Fortified breakfast cereals also contain vitamin B12.

The study included 1,459 older people whose vitamin B12 and folate levels were measured.

They were also given tests of their cognitive skills.

Dr Martha Savaria Morris, the study’s first author, explained the results:

“We found a strong relationship between high folate status and good cognitive function among people 60 and older who also had adequate levels of vitamin B12.”

Folates include vitamin B9, folacin and folic acid.

Some of the best dietary sources of folates include:

  • vegetables,
  • fruits,
  • liver,
  • and whole-grains.

Folate levels are particularly high in chickpeas, yeast extract, lentils and broad beans.

Dr Morris said:

“People with normal vitamin B12 status performed better if their serum folate was high.

But for people with low vitamin B12 status, high serum folate was associated with poor performance on the cognitive test.”

In contrast, low vitamin B12 was problematic:

“For seniors, low vitamin B12 status and high serum folate was the worst combination.

Specifically, anemia and cognitive impairment were observed nearly five times as often for people with this combination than among people with normal vitamin B12 and normal folate.”

People who may have difficulty getting enough vitamin B12 include vegetarians and those with some digestive disorders, such as Crohn’s disease.

Dr Morris concluded:

“Our findings support the often-expressed idea that many seniors would benefit from more folate, but the research shows that we must look at the effects this would have on seniors with age-related vitamin B12 deficiency, who may be more numerous than once realized.”

The study was published in the American Journal of Clinical Nutrition (Morris et al., 2007).

This Supplement May Be Key To A Longer And Healthier Life

Supplementation of this compound, also naturally found in animal proteins, has been called the elixir of life.

Supplementation of this compound, also naturally found in animal proteins, has been called the elixir of life.

Taurine supplementation extends the health and life span of middle-aged mice by 12 percent, research finds.

In humans it is also a semi-essential nutrient that is crucial for longevity and wellbeing.

Taurine is synthesised from cysteine in the pancreas, however, as the body does not produce enough, the rest must be obtained from the diet.

Also, taurine concentration drops as we age and the vegetarian and vegan population are at a higher risk of taurine deficiency.

For optimum levels, taurine can be obtained from high-protein foods such as meat, fish, and dairy, or taurine supplements.

Taurine plays a pivotal role related to the aging process: a deficiency reduces life expectancy, while supplementation could delay aging and help us look younger.

Taurine deficiency can lead to health issues such as hypertension, abdominal obesity, inflammation, type 2 diabetes, and aging-related diseases.

Animal research shows that taurine supplements slow the aging process by reducing DNA damage and improving an enzyme called telomerase which protects the ends of chromosomes.

Dr Vijay Yadav, the study’s senior author, said:

“For the last 25 years, scientists have been trying to find factors that not only let us live longer, but also increase health span, the time we remain healthy in our old age.

This study suggests that taurine could be an elixir of life within us that helps us live longer and healthier lives.”

Taurine has been known for its role in improving bone density, supporting the immune system and nervous system function, lowering blood glucose, and increasing weight loss.

Exercise and taurine

Another study found higher levels of taurine in athletes compared to sedentary individuals.

To see the impact of exercise, they measured taurine levels in participants’ blood before and after a vigorous cycling session.

Normally sedentary individuals experienced increased amounts of taurine after the workout as was seen in runners, bodybuilders, cyclists, and other athletes.

Dr  Yadav said:

“No matter the individual, all had increased taurine levels after exercise, which suggests that some of the health benefits of exercise may come from an increase in taurine.”

Researches also compared the levels of taurine in different age groups and found that with aging a large quantity is lost.

For example, taurine levels in a 60-year-old person were only one-third of a five-year-old child.

Dr  Yadav said:

“That’s when we started to ask if taurine deficiency is a driver of the aging process, and we set up a large experiment with mice.”

Anti-aging process

The aging process adversely affects human health so as people are living longer staying healthy in older age is a challenge.

Scientists acknowledge that some molecules such as taurine are important in aging, if so, the process can be controlled.

With the knowledge that a molecule like taurine is a driver of aging, increasing its levels should slow aging and improve the ‘healthspan’ (being healthy for a longer span).

Dr Yadav said:

“We realized that if taurine is regulating all these processes that decline with age, maybe taurine levels in the bloodstream affect overall health and lifespan.”

Taurine supplementation

Dr Yadav and the team examined the effect of taurine supplementation on both health and lifespan in middle-aged mice and monkeys.

Daily taurine supplements for six months in monkeys and one year in mice provide remarkable health benefits.

It improved the immune system, lowered blood glucose and some markers of liver damage, increased bone density in the legs and spine, and prevented weight gain in monkeys.

Taurine supplements improved muscle endurance and strength, increased bone mass, reduced insulin resistance, increased energy expenditure, reduced weight, decreased depression-like and anxious behaviours in mice.

Taurine supplements reduced “zombie cells” which are old cells that continue living and produce toxins in the body.

It also increased telomerase, elevated stem cell levels important for healing tissues after injury, slowed DNA damage, and improved mitochondria function.

These experiments suggest taurine probably can increase longevity and improve health in humans.

Dr Yadav said:

“I think taurine should also be considered.

And it has some advantages: Taurine is naturally produced in our bodies, it can be obtained naturally in the diet, it has no known toxic effects (although it’s rarely used in concentrations used), and it can be boosted by exercise.

Taurine abundance goes down with age, so restoring taurine to a youthful level in old age may be a promising anti-aging strategy.”

The studies were published in the journal Science (Singh et al., 2023; McGaunn et al.,2023)

A Mental Sign Of Vitamin B12 Deficiency

Around one-in-eight people over 50 are low in vitamin B12 levels.

Around one-in-eight people over 50 are low in vitamin B12 levels.

Poor memory, problems with thinking skills and even depression have all been linked to vitamin B12 deficiency.

Lack of vitamin B12 has also been linked to brain shrinkage with age.

People with higher vitamin B12 levels are six times less likely to suffer brain shrinkage, one study has found.

Vitamin B12 levels can be boosted through supplementation or by eating foods such as dairy, liver, salmon and eggs.

People who may have difficulty getting enough vitamin B12 include vegetarians, older people and those with some digestive disorders, such as Crohn’s disease.

Along with cognitive warnings, a physical sign of vitamin B12 deficiency is weakness in the muscles.

A review of the research has found that vitamin B12 is important in improving muscle strength and function.

A B12 deficiency, along with other dietary factors, can contribute to sarcopenia, which is the gradual loss of muscle mass.

Sarcopenia can lead to falls and increase the risk of bone fractures, as well as other injuries.

Professor Jean-Philippe Bonjour, study co-author, said:

“The most obvious intervention against sarcopenia is exercise in the form of resistance training.

However, adequate nutritional intake and an optimal dietary acid-base balance are also very important elements of any strategy to preserve muscle mass and strength during aging.”

Other dietary factors are also important in maintaining muscles with age.

Naturally, getting enough protein, the building blocks of muscle, is vital.

Similarly, vitamin D also plays a role in maintaining strength.

More fruits and vegetables in general are good for health and also for musculoskeletal health.

In contrast, high intakes of meat and cereal grains can increase acidity in the body, which is bad for the muscles.

Dr Ambrish Mithal, the study’s first author, said:

“Strategies to reduce the numbers of falls and fractures within our aging populations must include measures to prevent sarcopenia.

At present, the available evidence suggests that combining resistance training with optimal nutritional status has a synergistic effect in preventing and treating sarcopenia.”

The study was published in the journal Osteoporosis International (Mithal et al., 2012).

A Cognitive Sign Of Vitamin B12 Deficiency

B12 deficiency is relatively easy to correct with a change in diet or supplementation.

B12 deficiency is relatively easy to correct with a change in diet or supplementation.

A poor memory can be a sign of vitamin B12 deficiency, studies find.

People with a vitamin B12 deficiency sometimes have worse memories for both events and ideas.

Indeed, low levels of vitamin B12 and folate have both been linked to a higher risk of Alzheimer’s disease.

Folates include vitamin B9, folacin and folic acid.

Memory problems are one of the key symptoms of Alzheimer’s.

This link has been observed by researchers for more than three decades.

A deficiency in B12 or folate can cause higher levels of the amino acid homocysteine in the body.

Homocysteine has a neurotoxic effect and could lead to neurological conditions, such as Alzheimer’s.

One study followed 370 people over 75-years-old for three years.

In that time, 78 had developed Alzheimer’s disease, with more than half having a vitamin B12 or folate deficiency.

Dr Hui-Xin Wang, the study’s first author, said:

“In our study, we found that low levels of either of these two vitamins were related to an increased Alzheimer’s disease risk.

Monitoring B12 and folate levels is important in order to avoid unfavorable conditions, even for those elderly people who are quite healthy in terms of cognition.”

The good news is that B12 deficiency is relatively easy to correct with a change in diet or supplementation.

Good sources of vitamin B12 include liver, beef, fish, poultry, eggs and low-fat milk.

Fortified breakfast cereals also contain vitamin B12.

People who may have difficulty getting enough vitamin B12 include vegetarians and vegans, older people and those with some digestive disorders, such as Crohn’s disease.

If taking supplements, be careful not to have more than 2 mg per day — any more could be harmful.

The study was published in the journal Neurology (Wang et al., 2019).

A Warning Sign Of Vitamin B12 Deficiency

Around one-in-four people may have a vitamin B12 deficiency, according to research.

Around one-in-four people may have a vitamin B12 deficiency, according to research.

Small white spots on the skin can be a sign of vitamin B12 deficiency.

The white spots often appear on the outside of the forearm, but can be anywhere.

Around one-in-four people may have a vitamin B12 deficiency, according to a recent study.

The body uses vitamin B12 to make red blood cells and to keep the nervous system healthy.

Vitamin B12 deficiency can lead to low levels of melatonin, which contributes to the white spots on the skin.

Other, more common signs of vitamin B12 deficiency include feeling tired, experiencing muscle weakness and being constipated.

Vitamin B12 levels can be boosted through supplementation or by eating foods such as dairy, liver, salmon and eggs.

The study examined blood samples from 1,079 older adults in Germany.

The results showed that 27 percent were deficient in vitamin B12.

Along with this, over half were vitamin D deficient.

Ms Romy Conzade, the study’s first author, said:

“The results are very clear.

Fifty-two percent of the examined older adults had vitamin D levels below 50 nmol/L and thus had a suboptimal vitamin D status.”

Dr. Barbara Thorand, study co-author, said:

“Our study also shows that regular intake of vitamin-containing supplements goes along with improved levels of the respective vitamins.

However, vitamin-containing supplements are not a universal remedy, and particularly older people should watch out for maintaining a healthy and nutritious diet.”

The study was published in the journal Nutrients (Conzade et al., 2017).

The Vitamin Linked To Higher IQ

Deficiency in this vitamin is very common.

Deficiency in this vitamin is very common.

Higher vitamin D levels during pregnancy are linked to higher IQ among children, research finds.

Unfortunately, vitamin D deficiency is common in the general population and especially among Black people.

Around 80 percent of Black pregnant women may be deficient in vitamin D.

Ms Melissa Melough, the study’s first author, explains:

“Melanin pigment protects the skin against sun damage, but by blocking UV rays, melanin also reduces vitamin D production in the skin.

Because of this, we weren’t surprised to see high rates of vitamin D deficiency among Black pregnant women in our study.

Even though many pregnant women take a prenatal vitamin, this may not correct an existing vitamin D deficiency.

I hope our work brings greater awareness to this problem, shows the long-lasting implications of prenatal vitamin D for the child and their neurocognitive development, and highlights that there are certain groups providers should be paying closer attention to.

Widespread testing of vitamin D levels is not generally recommended, but I think health care providers should be looking out for those who are at higher risk, including Black women.”

The study included over 1,500 women and their children, who were tracked over five years.

The results showed that children had higher IQs at 4-6 years old when their mothers had higher vitamin D levels during pregnancy.

Ms Melough said:

“Vitamin D deficiency is quite prevalent.

The good news is there is a relatively easy solution. It can be difficult to get adequate vitamin D through diet, and not everyone can make up for this gap through sun exposure, so a good solution is to take a supplement.”

The recommended daily intake for vitamin D is 600 IU.

The average intake in the US is just 200 IU, with the remainder required from exposure to the sun.

Unfortunately, most people do not get enough exposure to the sun, especially in the winter months.

Foods that contain high levels of vitamin D include cow’s milk, breakfast cereals, fatty fish and eggs.

Ms Melough said:

“I want people to know that it’s a common problem and can affect children’s development.

Vitamin D deficiency can occur even if you eat a healthy diet.

Sometimes it’s related to our lifestyles, skin pigmentation or other factors outside of our control.”

The study was published in The Journal of Nutrition (Melough et al., 2020).

Vitamin D Deficiency: How To Tell If You Have It

Up to 50 percent of the population of the world is deficient in vitamin D.

Up to 50 percent of the population of the world is deficient in vitamin D.

Weak muscles can be a sign of vitamin D deficiency, research finds.

Older people with weak muscles are twice as likely to have a vitamin D deficiency.

Skeletal muscles which are connected to bones, give us the ability to move, balance, and perform physical activities.

Keeping skeletal muscles healthy is important for successful ageing because better mobility and reduced weakness will improve quality of life.

The signs and symptoms of vitamin D deficiency can vary, but some common ones include:

  1. Fatigue and tiredness
  2. Bone pain and muscle weakness
  3. Depression
  4. Impaired wound healing
  5. Hair loss
  6. Bone deformities
  7. Frequent infections or illnesses
  8. Slow wound healing
  9. Soft or brittle bones

Many of these symptoms can also be caused by other factors and some people may not experience any symptoms at all.

Vitamin D and muscle strength

Adequate levels of 25-hydroxyvitamin D appear to be as important as resistance training, such as weight exercises, in maintaining muscle function.

To determine the relation between poor muscle function and vitamin D, the study analysed data from 4,157 people who were 60 years and older.

They were given some physical performance tests, including the Short Physical Performance Battery (SPPB) and hand grip strength to measure participants muscle strength and physical function.

Their serum 25(OH)D concentration was also measured for vitamin D status.

Vitamin D deficiency was defined as a serum level below 30 nmol/L, the cut-off point which is used for bone disease.

They found that muscle weakness in people with vitamin D deficiency was double the rate than those with adequate levels of vitamin D.

Also, poor physical performance and low muscle strength was three times higher in participants with vitamin D deficiency.

Dr Maria O’Sullivan, the study’s co-author, said:

“Our results show that vitamin D deficiency increased the likelihood of poor muscle function in older adults and confirms the protective effect of physical activity.

Maintaining muscle function is incredibly important, and often overlooked, in promoting healthy ageing.

Addressing this through multimodal approaches that incorporate physical activity, reversing vitamin D deficiency and other modifiable diet and lifestyle components require further investigation.”

50% are vitamin D deficient

According to experts, up to 50 percent of the population of the world is deficient in vitamin D.

Vitamin D deficiency is linked to poor immune function, sleep quantity and quality, low mood, muscle fatigue, difficulties with learning and memory, gut problems, and headaches.

Another study reveals that people with low levels of vitamin D are likely to wake more during the night and to have less sleep overall.

Dr Eamon Laird, the study’s co-author, said:

“Vitamin D deficiency and physical activity are modifiable factors.

Some countries, for example Finland, have successful implemented a vitamin D food fortification policy which has all but eliminated deficiency in the population.

Such a policy could similarly be implemented in the UK and Ireland for older populations.”

The study was published in the journal Clinical Interventions in Aging (Aspell et al., 2019).

A Common Mineral Deficiency Linked To Mental Health Issues (M)

One-quarter of the world’s population has this mineral deficiency that is linked to anxiety, depression and schizophrenia.

One-quarter of the world’s population has this mineral deficiency that is linked to anxiety, depression and schizophrenia.

An iron deficiency is the most common nutrient deficiency and it can impact mental health, research finds.

Low iron levels can exacerbate symptoms of anxiety, depression and schizophrenia.

Many people with depression, for example, have a history of anaemia.

Higher rates of anxiety disorders, sleep disorders and psychotic disorders are linked to an iron deficiency.

It has been linked to mental health problems in both young and old.

An iron deficiency is frequently linked to symptoms of fatigue — which often combines with depression.

Dr Stephanie Weinberg Levin, the study’s first author, said:

“We don’t always go looking for nutrient deficiencies, but they can really take a large toll on well-being.

Iron is the most common nutrient deficiency and can have a big impact.

You can be iron-deficient without having anemia, but many mental health care providers aren’t aware that iron deficiency by itself has been linked to worse symptoms, or that supplementation has been linked to improved symptoms.

But there is evidence there.”

Mild iron deficiency

The researchers examined multiple studies on the connection between iron deficiency and mental health.

Many have found that iron supplementation appear to improve the symptoms of those with and without mental health diagnoses.

Supplementation can even help with relatively mild iron deficiency.

The usual benchmark for iron deficiency is 30 ng/mol.

However, one study found that supplementation for those with levels below 100 ng/mol was beneficial for negative mood and fatigue (Mikami et al., 2022).

Which type of supplement?

Iron deficiency should be treated by supplementation, since the typical diet cannot provide enough, the study’s authors write.

Most types of iron supplementation will work, however, the disadvantages of supplementation are that 70 percent of people experience side-effects.

These can include a metallic taste in the mouth, vomiting, nausea and constipation/diarrhoea.

So, the key is to find the type that has the lowest side-effects.

Ferrous sulfate is the cheapest, but other forms, such as ferrous iron protein succinylate and ferrous bisglycinate may have fewer gastrointestinal side-effects (but they are more expensive).

How much iron?

As for the amount, there is no clear guidance, but the study’s authors suggest:

“The maximum amount of oral iron that can be absorbed is approximately 25 mg/d of elemental iron.

A 325 mg ferrous sulfate tablet contains 65 mg of elemental iron, of which approximately 25 mg is absorbed and utilized.”

Supplements should be taken for 6 to 8 weeks and it may take 6 months for the body’s iron stores to be replenished.

Dr Levin concluded:

“Iron supplements are inexpensive and can really make a significant impact in someone’s mental health if they’re deficient.”

Note that a physician should be consulted: people with inflammatory bowel conditions, chronic kidney disease or the pregnant should not take iron supplements orally.

The study was published in the journal Current Psychiatry (Levin & Gattari, 2023).

A Throbbing Sign Of A Vitamin D Deficiency

Diseases linked to vitamin D deficiency include cardiovascular disease, diabetes and cancer.

Diseases linked to vitamin D deficiency include cardiovascular disease, diabetes and cancer.

Throbbing pains in the back or knees could be signs of vitamin D deficiency.

The pain can feel like a penetrating ache sensed deep in the body.

Aching bones are linked to vitamin D deficiency because it is vital to bone health.

The substance is required to help regulate the levels of calcium and phosphate in the body.

A 10 mcg supplement is typically enough during the winter months to supplement dietary intake.

Vitamin D deficiency can be detrimental to overall health as well.

Deficiency in this vitamin has also been linked to multiple sclerosis, high blood pressure and diabetes.

Other possible signs of vitamin D deficiency include depression, feeling sleepy and a lack of energy.

Some studies estimate that up to 70 percent of people could have a vitamin D deficiency.

Much of the body’s vitamin D is produced in response to sunlight on the skin.

That is why levels are typically lower in the body through the winter months in northern latitudes.

Getting outside for a 20-minute walk a few times a week can be enough for the body to produce the required amounts of vitamin D.

Some of the best dietary sources of vitamin D are eggs, oily fish and mushrooms.

One study of postmenopausal women found very high levels of vitamin D deficiency.

The study’s authors recommend that:

“A healthy lifestyle should include exposure to the sun for 15 minutes three to four times per week when the weather permits since 90% of vitamin D is synthesized upon the skin having contact with sunlight.”

Many health problems could be linked to vitamin D deficiency, said Dr Faustino Pérez-López, the study’s first author:

“We believe that many diseases can be aggravated by a chronic deficiency of vitamin D.

Healthcare professionals should be aware that this is a common problem which affects a large part of the population in Europe, even those who live in sunny places.”

Vitamin D supports the mineral density of bones and aids neuromuscular function as well as reducing the risk of fracture.

Other disease linked to vitamin D deficiency include cardiovascular disease, diabetes and cancer.

The study was published in the journal Maturitas (Pérez-López et al., 2012).
