The Power Of Vitamin D

The Most Underrated Nutrient For Your Brain & Body*

Research shows vitamin D helps regulate over 2,000 genes and is essential for brain health, emotional balance, and immune strength.* But an estimated 42% of U.S. adults are vitamin D deficient, with even higher rates in colder seasons or among people who spend most of their time indoors.* And that matters: studies show that low D levels may be as harmful to your health as smoking.*²

The good news? One high-potency capsule a day can help restore healthy levels and support how you think, feel, and function—year-round.*

Glad to be taking Vitamin

"Glad to be taking Vitamin D3, 5000 IU, Trying to boost my serotonin level which Vit. D3 achieves when one does not get enough D3 from the sunshine. There is also a Serotonin supplement offered, and I do not know which to take, so I decided on D3. I do. not wish to overdo getting a Serotonin boost. Also, am interested in D3 with K2 which I am contemplating, but my Brain and Body Power has a small amount of K2 in it, and I do not know how much K2 is desirable. Wish someone could help me on this K2 decision. Overall, I love Dr. Amen's supplements."
