But it may not help much to take a multivitamin pill since the amounts of vitamins in these pills are about, or below, the recommended daily allowance which you are probably getting from your food anyway if you are eating a good diet. To overcome poor absorption, considerably larger amounts are often needed — especially for vitamin B Such amounts of folate and B12 are often added to breakfast cereals.

Vitamin B9 is known as 'folate' in its natural form and 'folic acid' in its synthetic form. It's the folic acid form that's used in dietary supplements and foods.

Our research in Oxford found that, in normal older people, the level of vitamin B12 in the blood is related to the rate at which the brain shrinks. We found that people with mild cognitive impairment benefitted greatly from a B vitamin mixture folic acid, vitamins B6 and B12 : the rate of brain shrinkage was much reduced and their cognitive decline was markedly slowed.

The main vitamin turned out to be B12 0. Omega-3 fatty acids may protect the brain, for example from shrinking and perhaps from cognitive decline. In Oxford, we have found that the beneficial effects of B vitamins on the brain are enhanced in people with good omega-3 status. Our usual diet does not contain enough omega-3 and we need to eat fish at least once a week to get this nutrient.

Even then, we may not get enough so an intake of between 1 and 2 g per day of total omega-3 from fish oil capsules is my recommendation.

For vegetarians and vegans, there are capsules that contain omega-3 from algae. Vitamin D is formed by the action of UV light on the skin, but most of us do not get enough sun when we age. It is important to take supplements of vitamin D to protect your bones, but also to protect the brain.

My view is that we should take micrograms per day of vitamin D3. You may have heard about a possible role for other types of nutrients in brain health — for example, antioxidants, flavonoids and other vitamins such as C and E. Nutritional supplements in large amounts can have side-effects.

If you have any concerns or questions about taking supplements, please discuss them with your doctor. Read more about evidence for supplements for your brain in a report from The Global Council on Brain Health.

Lutein, Zeaxanthin, and Meso-Zeaxanthin are powerful, plant-based nutrients found in leafy greens like spinach, kale, and broccoli. Diet alone is not enough to prevent brain fog and enhance brain focus. Carotenoids are antioxidants with protective abilities that work to neutralize free radicals and reduce stress on the brain.

Brain supplements for memory and focus must contain the essential fatty acids, Omega-3s. They are vital nutrients for normal brain function and development throughout all stages of life, including pregnancy and early childhood.

They also work to preserve cell membrane health and facilitate communication between brain cells. Memory Health memory supplements include mg DHA and mg EPA to help rebuild new cells with healthy cell membranes.

These cell membranes provide critical support for the brain connections that support healthy memory, cognition, and emotional well-being.

Lower levels of DHA is associated with deficits in learning and memory as well as accelerated brain aging. Memory Health uses the antioxidant D-Alpha Tocopherol Natural Vitamin E , to slow down oxidation of these memory pills to maintain its integrity and bioavailability of the product. Vitamin E also provides powerful antioxidant properties to reduce oxidative stress.

The best brain focus and memory supplements are easy to swallow! Memory Health uses food grade and FDA approved gelatin for a softgel casing. These gel capsules work as a brain booster and focus supplement.

Memory Health focus pills and brain fog supplements use Lutein, Zeaxanthin, and Meso-Zeaxanthin for the enhancement of cognitive function and brain health. We harvest these carotenoids using a patented process from organic marigold flower petals. This brain health supplement delivers key nutrients to help protect the brain from degeneration.

Concentration supplements or nootropics brain support supplements can often have an unpleasant taste due to the Omega-3 fish oils. We've added a delicious natural lemon flavor to the Memory Health brain memory supplements.

The analysis of effects on daily life found no difference between ginkgo biloba preparation and placebo. Side effects of ginkgo supplements may include headache, nausea, gastrointestinal upset, diarrhea, dizziness, or allergic skin reactions.

More severe allergic reactions have occasionally been reported. There are some data to suggest that ginkgo can increase bleeding risk. Omega-3 Fatty Acid Supplements. Among the nutritional and dietary factors studied to prevent cognitive decline in older adults, the most consistent positive research findings are for omega-3 fatty acids, often measured as how much fish people consumed.

The result was consistent for all outcomes relevant for people with dementia. A systematic review and meta-analysis of 38 randomized controlled trials with a total of 49, participants assessed effects of higher vs lower omega-3, omega-6, or total polyunsaturated fats and outcomes on new neurocognitive illness, new cognitive impairment, or global cognition.

The reviewers concluded that long-chain omega-3 probably has little or no effect on new neurocognitive outcomes or cognitive impairment and noted that the effects of increasing α-linolenic acid, omega-6, or total polyunsaturated fatty acid were unclear. Further, a Cochrane review of 3 randomized controlled trials involving more than 3, participants concluded that available evidence shows no benefit of omega-3 supplementation on the cognitive functioning of older people without dementia.

Omega-3 fatty acid supplements usually do not have negative side effects. When side effects do occur, they typically consist of minor gastrointestinal symptoms. Vitamin E.

I study supplementation and have studied lutein for brain health alongside Zeaxanthin, Omega 3 DHA and EPA. This also contains vitamin E which is good for overall body health. Lutein and Zeaxanthin are commonly associated with eye health.

However, studies have emerged over the last few years that have demonstrated the power of these supplements on the brain. It is encouraging to say the least. This supplement has helped me maintain focus and does seem to take my health in a positive direction. I am able to keep up with life's demands and have a positive attitude.

Having the right fatty acids and brain protection can help with overall mood. I have recommended the ingredients of this supplement to family and friends because it is simple yet powerful. It is only a thirty-day supply and could easily be obtained in larger quantities in individual supplements.

This is currently being sold as a premium nutritional supplement. This could readily available as a basic supplement. The research and claims behind this supplement do not change what is actually in the bottle.

Overall, this is powerful nutrition and should be sought out. I do recommend this as a top choice. More Hide. Thank you for your feedback. Sorry, there was an error. Sorry we couldn't load the review.

Vine Customer Review of Free Product What's this? I really like how the dosages are set apart as a per-dosage basis. It is nice to grab the packet when I need to take the amount for the day and it is nicely laid out in a simple, single packet.

These are little gel-like capsules that are easy to swallow, don't give me any gross or bad-tasting after tastes or anything like that , and they do feel to be helping with some memory stuff but I hope it is not placebo. I have been taking for about a month and it seems like recall is a bit better and retention is as well.

There also seem to be some very good longterm impacts as a few of the ingredients appear to be used to either prevent or treat some eye diseases.

Eye care is important to me so I really appreciate the fact this helps with that also. Something that I would like would be some more transparency concerning independent lab testing and things like that.

It is nice when that is included as it helps underscore that what you are taking is safe and pure. This product doesn't have a ton of information so the onus of research is on me to make sure my doctor approves of it, etc.

Pros: Seems to help with memory recall Memory retention feels a bit better Love the single-serving packets Good for eyes, longterm Cons: No independent test results Value is just okay I think that this will be a lot more effective for some people rather than everyone as we all process things differently.

As far as the longterm benefits; I won't know them for hopefully many years. Steady, Consistent Improvement. Three words I would use to describe my experience with Memory Health.

For most of my adult life I have suffered with bouts of brain fog. A few years ago, as I approached menopause, the fog became worse and I began noticing other issues as well. I was quite worried and decided to try Memory Health. I would surprise myself by being able to recall a name or tidbit of information.

It was surprising because I had fearfully become so accustomed to not remembering. As the months progressed, I faced less anxiety when confronted with tasks. I have always exercised and maintained a relatively clean diet.

As a matter of fact, I tend to be less than consistent with supplements but because of the difference I have experienced, Memory Health has been the exception.

I will continue to take it as long as I am able. My mom and I purchased these to try out. I tried them first to be the guinea pig. I took only 1 pill a day for a week dosage is 3 a day and I had horrific heartburn!!!

So these were a no for me, which was very disappointing. I passed them along to my husband to try. Hopefully he will do better. So far so good. Memoria fresca. Translate review to English. Recommended by my neurologist. Might help. One person found this helpful. See more reviews.

Excessive selenium intake, or selenosis, may result in hair and nail loss or brittleness, lesions of the skin and nervous system, nausea, diarrhea, skin rashes, mottled teeth, fatigue, irritability, and nervous system abnormalities.

Excessively high levels of calcium in the blood known as hypercalcemia can cause renal insufficiency, vascular and soft tissue calcification, hypercalciuria high levels of calcium in the urine , and kidney stones. High calcium intake can cause constipation. Excess amounts of vitamin D are toxic.

Because vitamin D increases calcium absorption in the gastrointestinal tract, vitamin D toxicity results in marked hypercalcemia, hypercalciuria, and high serum 25 OH D levels. Short-term use of melatonin supplements appears to be safe for most people, but information on the long-term safety of supplementing with melatonin is lacking.

Studies of Bacopa monnieri also show that it may occasionally cause diarrhea and an upset stomach. Because of this, many people recommend taking this supplement with food Bacopa monnieri has been shown to improve memory and thinking skills in healthy people and in those with a decline in brain function.

Rhodiola rosea is a supplement derived from the herb Rhodiola rosea , which is often used in Chinese medicine to promote well-being and healthy brain function. People taking Rhodiola rosea have been shown to benefit from a decrease in fatigue and improvement in their brain function 72 , 73 , However, results have been mixed A recent review by the European Food Safety Authority EFSA concluded that more research is required before scientists can know if Rhodiola rosea can reduce tiredness and boost brain function Rhodiola rosea may help improve thinking skills by reducing fatigue.

However, more research is needed before scientists can be certain of its effects. S-Adenosyl methionine SAMe is a substance that occurs naturally in your body. It may be useful for enhancing the effects of some antidepressants and reducing the decline in brain function seen in people who have depression 77 , 78 , More recently, a study found that, in some instances, SAMe may be as effective as some types of antidepressant medications SAMe could be useful for improving brain function in people with depression.

There is no evidence it has this effect in healthy people. However, note that many brain-boosting supplements are only effective for people who have a mental condition or are deficient in the supplemented nutrient.

A recent study that included 39, people found that low vitamin B12 levels were associated with poorer attention and memory Having low or deficient levels of other B vitamins, including vitamin B6 and folate , may also worsen symptoms of brain fog, including difficulties with concentration and memory 38 , For this reason, taking a high quality B complex supplement may help reduce the risk of these brain fog symptoms.

Low levels of certain B vitamins may worsen symptoms of brain fog. For this reason, taking a B complex supplement may help reduce brain fog symptoms in some people.

Some studies suggest that taking an L-theanine supplement may help improve mental alertness, reaction time, and memory. A recent study in 69 adults ages 50—69 found that a single dose of L-theanine supplements may also reduce tension and enhance calmness and relaxation Reducing stress, improving sleep quality, and supporting cognitive health may all help relieve brain fog.

L-theanine may reduce brain fog symptoms such as memory problems and delayed reaction time when taken as a supplement. It may also help reduce stress and improve sleep, which may relieve brain fog symptoms. Brain fog symptoms can be related to a number of factors, including nutrient deficiencies, lack of sleep , stress, and even undiagnosed medical issues.

Lack of sleep, a diet high in ultra-processed foods, and excessive alcohol intake have all been linked to poor memory, difficulty concentrating, depressive symptoms, and other cognitive issues that some people may describe as brain fog 44 , 45 , Many factors, such as nutrient deficiencies, medical issues, and sleep deprivation, may contribute to brain fog.

If you have brain fog, speak with a healthcare professional to rule out serious potential causes and find the proper treatment.

Some research suggests that certain supplements may be helpful for those experiencing brain fog symptoms. Having suboptimal or low levels of certain nutrients may contribute to or cause brain fog-related symptoms, so supplementation with these nutrients may help.

However, brain fog has many possible causes, some of which are serious. Our experts continually monitor the health and wellness space, and we update our articles when new information becomes available.

There is some evidence that a basic multivitamin supplement may boost cognition. A multivitamin supplement contains various micronutrients vitamins and minerals your body needs daily. While a multivitamin is recommended for certain populations such as those who are pregnant , it may not be necessary for everyone.

A healthcare provider can help you decide if you should take a multivitamin. New research shows that multivitamin supplement use may benefit older adults with memory issues. In a recent clinical trial, over 3, older adults were randomized to take a placebo or multivitamin daily for three years.

Those who took the daily multivitamin were found to have improved immediate recall memory. These improvements were sustained over the entire three-year trial period. As this is a newer area of research, more studies may be warranted to better determine if daily multivitamin use can improve cognition in older adults or other populations.

Nootropics or "smart drugs" are natural or synthetic supplements meant to support brain health and cognition. They contain substances that may be made in a lab or derived from plants. The majority of nootropics are natural herbs, however.

Like other herbal remedies, nootropics are considered a fairly safe supplement option. Very few have been found to cause serious side effects, but little is known about the safety of using nootropics long-term. Examples of nootropics include:.

There are numerous nootropics on the market, some with better research support than others. Some of the compelling research behind certain nootropics is outlined below.

Panax ginseng is an herb commonly used in traditional Chinese medicine and other types of alternative medicine. It is said to have properties that reduce the risk of neurodegenerative diseases or decline. When it comes to brain health, researchers from one review found that Panax ginseng may have the most positive effects on depression.

Compounds found in Panax ginseng are thought to cause antidepressant effects by interacting with certain cell signaling pathways. While much of the research on Panax ginseng for brain health has been performed in a laboratory setting, some human trials have been conducted.

In one large human trial, researchers compared long-term Panax ginseng users to nonusers. Compared to those who didn't use the herb, study participants who used Panax ginseng for long periods had higher cognition test scores later in life.

However, these effects were only seen with long-term use more than five years of Panax ginseng. The leaves from the Ginkgo biloba plant have been used to make herbal remedies for centuries. These leaves are used for many purposes in alternative medicine, including brain health.

A review of large-scale clinical trials on Ginkgo biloba found conflicting results regarding the herb's efficacy for cognitive functions. According to the review, Ginkgo biloba extract is most commonly used for cognitive decline, poor memory, and decreased alertness.

While many studies included in the review found no positive effects of Ginkgo biloba , several studies showed a potential role of the herb in treating cognition in patients with mild dementia.

Ginkgo biloba was most effective when used for at least 24 weeks and at a dose of milligrams mg per day. More research is needed to determine if Ginkgo biloba supplements work for brain health. Due to its perceived neuroprotective properties, ashwagandha Withania somnifera has been recommended as an herbal treatment for cognitive decline.

A clinical trial from looked at how ashwagandha use would affect healthy, stressed adults. After randomization, participants took either a placebo or an ashwagandha supplement for 90 days. Taking mg of ashwagandha root extract in a sustained-release capsule form per day was found to be safe and also led to improvements in memory, focus, sleep quality, stress, and overall psychological well-being.

Scientists believe that ashwagandha reduces oxidative stress in the central nervous system and, thus, may be beneficial for diseases such as Parkinson's disease , Huntington's disease , and Alzheimer's disease.

Some clinical trials have supported its use for brain health, but there isn't a clear consensus on how effective ashwagandha is. In some studies, healthy caffeine consumption has been linked to better cognitive performance. Caffeine is found in various foods and drinks, with coffee being the most popular option.

While a moderate dose of caffeine to mg has been shown to enhance alertness, a high dose mg or more may cause side effects like anxiety and trouble sleeping. According to one review, researchers agree that caffeine consumption improves basic cognitive functions like attention and reaction time.

However, there is less of a consensus among researchers on the effects of caffeine on "higher" cognitive functions like decision-making and problem-solving.

A review noted opposing results among several clinical trials on caffeine's effects on brain health. While there was not enough scientific evidence to support caffeine as an attention booster, there was evidence that caffeine improves both short-term and long-term memory in adults.

Hopefully, research will continue in this area so that the role of caffeine as a nootropic will become clearer. Regarding dietary supplements, you can't always believe everything you hear. This might be especially true for supplements marketed to boost brain health.

Many supplements that claim to boost brain health haven't been researched enough to support their use in everyone. Nevertheless, some researchers believe there simply isn't enough clear evidence to support using any dietary supplement for brain health.

This goes for people who are healthy as well as those with dementia or other neurodegenerative diseases. For at least a few dietary supplements, there isn't strong evidence that supports their use in brain health.

These include:. In general, more research is needed on the use of dietary supplements for brain health. As previously mentioned, many researchers have a hard time recommending supplements to improve your brain's health.

Besides the fact that brain health supplements may not do the work as intended, they also may come with safety concerns. Recall that dietary supplements are not tested for safety or effectiveness like prescription medications are.

This means that some brain health supplements may contain ingredients that either aren't listed on the nutrition label or are included in the supplement in amounts different than what is listed. When choosing a supplement , look for third-party tested products and consult a healthcare provider, registered dietitian nutritionist RD or RDN , or pharmacist.

To put this into perspective, a review of 12 supplements for brain health found just one to be third-party tested and actually contain what was listed on the nutrition label. For the most part, side effects are rare but possible when taking dietary supplements.

You are especially likely to experience side effects if you take too much of a supplement, so be sure to only use supplements as directed.
