Vitamin D3 5000

High potency cholecalciferol, the form of Vitamin D most effectively converted into a hormone with wide-ranging health benefits

Promotes Healthy Mood Management
In clinical studies, individuals sufficient in vitamin D (typically, blood levels higher than 50 nanomoles per liter) showed better mood and cognitive status than individuals who were insufficient or deficient. It has a fundamental importance for the neurotransmitter production, brain maintenance, and nerve cell renewal that underlie healthy mood.

Supports Healthy Circulation and Blood Flow to the Brain
Vitamin D3 has proven importance for heart and blood vessel health. Powerful meta-analyses (pooling of data) from clinical trials combined with epidemiologic (population survey) studies document that individuals with the highest vitamin D levels have healthier heart and vascular function than those with low levels.

Regulates Numerous Life Processes
This vitamin has powerful and extremely versatile effects on health and wellbeing. Within the past two decades researchers have confirmed its favorable effects on healthy gene regulation, calcium metabolism, cell growth control, hormone balance, and coping with stressful challenges.

Breakthrough Dietary Supplement for Quality of Life
Vitamin D deficiency is very common. People who are older, who have darker skin, use sunscreen, or otherwise get limited sun exposure are at risk for deficiency. Common medications can also deplete vitamin D. Additionally, many experts are convinced the current recommendations underestimate the daily intakes needed for good health. Sufficiency of vitamin D3 promotes healthy mood, cognitive function, cardiovascular function, immune response, muscle and bone strength, and other important indicators of overall vitality.


Getting my vitamin D back up

I have been deficient in vitamin D a few times and have had to take prescription strength pills. I never noticed a difference until I started taking these. I am less tired and I have more energy. My vitamin D level is up in the 50s now. I just ordered my second bottle.

Sun kissed from within.

Taking this supplement has aided in my feeling well. I noticed I was losing weight and found that if one is low on Vit D and need it and then takes it, they will lose during the first month of finally getting the amount they need. Worked for me even though that wasn't part of why I took it.

Best Vitamin D You Can Buy!

Terrific product!

Helped me reach optimal Vit D level

My Vitamin D levels have been down for a while, I switched to this supplement, Dr. Amen's Vitamin D3 5000, taking it as recommended by my provider. A few weeks later, my most resent blood test showed my Vit D level is near optimal! Woohoo!

Mother approves.

My mother takes this supplement. She says her mood & energy has improved.


After blood work showed I was slightly D deficient, I started researching quality supplements. I was also at the time listening to Dr. Amen's book on ADD and he recommends vitamin D. I started taking these back in April. I get blood work done at the start of next year. This is 1 of 5 supplements from Dr. Amen I currently take and have experienced a definite change in my mood, focus, energy, and concentration. I love them all!

I give this 5 stars because I know I reap the benefits even without the lab result. My body tells me.

I was taking at least 20,000 units in the past everyday yet my level was only 36. I realized my poop was expensive since all those vitamins just slid thru my body into my gut and out as poop. I was not absorbing them well. Then I tried Dr. Amen's, I was more alert, happier and just feeling relaxed. My feet were not cold anymore. I've recently run out just when I'm about to get my annual physical. My feet are cold and I'm sleepy and sluggish. I was back just like before although this time it's not very severe. I have postponed my checkup for three months. This should give me enough time to catch up on my missed weeks and I will update here. The July sale helps me able to order more. Thanks.

Vitamin D is a must

I take these high-quality vitamins daily. All women should take them. I will be testing my Vitamin D levels shortly after trying this out for 6 months.

Highly Recommend

I have been taking Dr. Amen's Vitamin D3 consistently for almost a year now. My level has gone from 36 to 70 and I can feel the difference! My doctor was so impressed, she even asked me which brand I was taking and said she'd not seen numbers change that drastic in that amount of time. I recommend all of Dr. Amen's products to everyone I know.

Five Stars

Highly recommended. I am vitamin D deficient and I use these daily in the morning. It's easy to swallow and do not upset my stomach.


Couldn't live without this! Good quality Vit D is hard to find!

The sun in a bottle

Perfect for someone that never sees the sun!

Great product.

My Vitamin D levels are in the upper normal range!

Loving it!

I am loving the BrainMD products. The Vitamin D has helped my memory and has smoothed the rough edges on my mood. I find myself a lot more tolerant of other people now. Taking it along with the Omega 3 is a must every day and I have now ordered the Restful Sleep. Can't wait till it gets here so I can give it a try.

Helped me beat the Wisconsin Winter Blues!

Winters are long and cold out here, this product really helped me get through this last one. I've had struggles with my mood during the long winters in Wisconsin. I must say, this last one was the easiest one yet! I have so many new things riding on my shoulders and yet I didn't fall victim to the normal winter blues that I usually deal with. I will order it again this coming winter:)

great product

Vit D3 is so important to be healthy. With winter and sunscreens I wondered if I was deficient in D. Been taking Dr. Amen’s Vit D for some time- a brand I trust to be pure and good. Recently had a blood test workup - my Vit D levels were great!

Really works

I had suspected I was low in Vitamin D. I know that this supplement is very effective. For sure, I will be reordering. I feel really good.

Ingredients & Facts

  • Vitamin D
    Vitamin D used to be considered just a bone vitamin. But intensive research established that the body converts it into a hormone that also helps regulate brain, cardiovascular, immune, muscle, lung, joint and kidney functions. Vitamin D is important for the brain's early development and ongoing renewal, and in clinical trials it promotes healthy mood management and cognitive functions. It also benefits numerous other functions that promote healthy aging. U.S. government and other surveys report vitamin D deficiency is common in all population groups. It's called "the sunshine vitamin" because ultraviolet light stimulates the skin to make it. But people with dark skin, pregnant women, the elderly, those living far from the equator, and others with limited access to sunlight are at risk of being deficient. Vitamin D3 5000 from BrainMD Health is high-purity D3 (cholecalciferol), the body's preferred vitamin D form. It is safe to take long-term, and formulated to help ensure ongoing sufficiency of vitamin D in the blood and the tissues.

Frequently Asked Questions

Does vitamin D2 work the same as this form?
No. Vitamin D3 is the body's preferred form, and D2 may negatively interfere with the normal utilization of D3 by the tissues.
Does this product work better with calcium?
Not necessarily. Vitamin D3 does not require calcium supplementation for its many benefits. This product actually is not recommended for people with blood calcium levels higher than the normal range.
What is the best blood level of vitamin D?
The current expert consensus is that a serum 25-hydroxyvitamin D of 75 nanomoles per liter or above is approaching optimal, and that levels below 50 nanomoles per liter indicate deficiency.
Is this daily dose safe to take long-term
The clinical studies suggest that toxicity need not be a concern for most adults unless they consume more than 10,000 IU daily. When used below this level as recommended, vitamin D3 is very safe. Be sure to take it with meals because it is a "fat-soluble" vitamin.
