Research-Supported Benefits:

Supports Healthy Aging. Aging can impact how vitamin D is metabolized in the body increasing the risk of skeletal health issues as well as other age-related health concerns such as impaired brain health, lowered immune function and heart health concerns. Research demonstrates supplementing with vitamin D may help maintain healthy vitamin D levels with age and reduce the risk of age-related health concerns.1

Supports Bone Health. Bone remodeling occurs throughout our lifetime. As we age, the rate of bone tissue generation decreases leading to skeletal weakness and frailty. Research shows that vitamin D, in combination with calcium, can increase bone tissue formation, strength, and density.2, 3

Supports Immune Health. Decreased immunity is common among those over 40. Low levels of vitamin D have been associated with increased bacterial and viral infections. Maintaining appropriate vitamin D levels has been shown to improve the innate and adaptive response of the human immune system, including dental and intestinal infections.4

  • Vitamin D, a fat-soluble vitamin, is essential to maintaining total body health, yet is not found in many foods. It's needed daily to keep bones and teeth strong over your lifetime, and to ensure the proper functioning of the heart, muscles and nerves - it even helps your blood to clot. A daily regimen of this D3 (cholecalciferol) is the best way to treat and prevent vitamin D deficiency, whether from lack of sunlight, poor nutrition, chronic illness or aging.
  • D3 Extreme™ offers support for healthy bones and supports the immune system by maintaining normal blood levels of calcium and phosphorus, thus promoting calcium absorption.

Highest dosage of Vitamin D3

I've been taking Vitamin D3 Extreme for several years now as it was recommended by my doctor. I wasn't able to find the 50,000 IU capsules at any of the local retail pharmacies but was able to order it from ProHealth. It gives me the right amount of Vitamin D3 which I just take every other week to keep my bones strong.
