The Best Vitamins for Memory Improvement

What are the best vitamins for memory? While there is no miracle cure for a bad memory, the vitamins listed below may be able to help.

A word of caution: Everyone has heard there are vitamins and supplements that can improve your memory and other brain functions. Research indicates this may be true.

However, success in using vitamins for memory improvement varies. Some products work better for some people than others. Each of us have different genetics, health and diet, and natural memory ability, which may partially explain this.

And don't forget: what you eat and drink and the quality of your sleep have a powerful effect on your memory, too. Taking vitamin pills won't offset an unbalanced lifestyle.

So do your own research before trying any vitamins or supplements. Read the labels and product reviews. Evaluate the advice and tips from people who have used the products. Consult your physician as appropriate for your situation. This is common sense.

Below is a list of vitamins for memory, followed by a longer list of supplements that may have a positive effect on memory and brain function. A brief description and background information are included for each one. All are legal in the U.S. and readily available from health food stores, nutrition shops, and online stores such as

Below are three types of vitamins for memory improvement you may wish to consider taking. Studies indicate these vitamins are essential for the brain and memory to operate at its best. For many people, vitamin pills are an easy way to help them get enough of these vitamins in their daily diet.

The following are vitamins that can affect memory and brain power:

B VITAMINS. Research shows that B vitamins improve memory by creating a protective shield for the neurons in the brain.

B vitamins break down homocysteine, which is an amino acid that is a toxic poison to nerve cells. These vitamins also aid in the production of red blood cells, which carry oxygen, an important brain nutrient.

The most important B vitamins for memory include B6, B12, and Folic Acid (B9).

You can increase the B vitamins in your diet by taking vitamin supplements and by consuming healthly, natural foods such as spinach and other dark, leafy greens; broccoli, asparagus, strawberries, melons, black beans, leeks, and other legumes, citrus fruits such as oranges and grapefruit, and soybeans.

ANTIOXIDANTS. Vitamins C, E, and beta carotene are antioxidants and are also important vitamins for memory. Antioxidants protect brain tissue by breaking down free radicals, which are toxic forms of the oxygen molecule natually found in the bloodstream.

Antioxidant vitamins and memory are linked because the damage free radicals do can impare the functioning of the neurons in your brain. Like the B vitamins, in other words, the antioxidant vitamins prevent damage to the basic brain structures.

Supplementing with antioxidant vitamins daily is recommended. In addition, these vitamins can be found in naturally occurring foods such as blueberries, strawberries, and other berries; sweet potatoes; red tomatoes, spinach, broccoli, green tea, peppermint tea, and other types of herbal tea; nuts and seeds; and citrus fruits such as oranges and grapefruits.

Note that with some of these foods, you get both the B vitamins and the antioxidants - a double dose of vitamins for memory improvement!

buy on amazon
OMEGA FATTY ACIDS. Omega-3 fatty acids are not really "vitamins" as such, but important fat molecules that enhance memory and brain function.

So much is said about so-called bad fats, but the Omega-3 fatty acids are actually a class of good fats.

These fats help protect the brain against inflammation and high cholesterol. That's what makes these fatty acids good vitamins for memory improvement.

Benefits of fish oil supplements

Good sources of Omega-3 fatty acids include cold-water fish such as salmon, herring, tuna, halibut, and mackerel; walnuts; and flaxseed/flaxseed oil.

In addition to taking regular vitamins for memory improvement, you might also want to try memory and brain enhancing supplements. Keep reading to learn more.

Memory supplements

Supplements are similar to vitamins, and may even contain vitamins, but are generally available in pill form only and not necessarily in food. See the examples below - you'll understand what I mean!

I've included references to published research studies for most of these supplements. However, the few references listed here are examples only and not meant to be comprehensive. Also keep in mind that scientific research is an ongoing process with new developments and discoveries happening all the time.

These supplements are listed in alphabetical order. I don't advocate any of them in particular. It's up to you and your physician to determine which supplements (if any) are right for your situation.

About the Memory Supplements List

Brain power

The list of brain supplements above is not meant to be complete. There may be other vitamins for memory and related supplements not included here that do have some effectiveness. Having said that, this list should be of value if you are interested in learning about some of the memory and brain supplements that are popular and supported by research.

I've attempted to focus on those which are backed up by credible studies. I have intentionally not included supplements associated with claims of enhanced memory and brain power but for which I was not able to find much scientific evidence (for example, phosphatidyl choline and l-glutamine).

I've also not included every supplement that may boost your physical energy, thus possibly enhancing concentration and attention span, but which doesn't necessarily aid memory directly (for example, ATP and caffeine). Finally, I've not listed any "blends", or products in which multiple brain supplements have been mixed together.

How Necessary Are Memory Vitamins and Supplements?

For many people, it may not be necessary or helpful to take any vitamins for memory improvement or any of the related supplements. Lifestyle changes including a healthier diet, an appropriate exercise program, and more restful sleep could be all that's needed for an acceptable level of memory and brain health.

From a dietary perspective, for example, consider eating more brain foods such a serving of cold-water fish a couple times per week. And try to consume more of the fruits and vegetables that contain B vitamins and antioxidants.

Vitamins and supplement pills are just that, supplemental. They are "add-ons", not the main thing. Achieving a healthy lifestyle should be your first goal.

But for those who have already optimized their diet, exercise, sleep habits, etc., and who are looking for something extra, vitamins for memory and related brain supplements may give them that edge. In fact, you might want to look into the idea of supplement stacks to help you decide which vitamins and supplements to combine.

Before trying any of these products, however, do your due diligence (i.e., do your own research). And be sure to talk to your doctor first as appropriate for your situation.

Reminder: The information on this website is not medical advice. It is for informational purposes only. Consult your physician before making any dietary changes that may affect your health.
