$ 29.00

O2B Vitamin D3 capsules provide an important building block and gene regulator for supporting strong and healthy bones, the immune and endocrine (glandular) systems, and is needed for optimal mental and cardiovascular health.

Vitamin D deficiency is surprisingly relatively common, and deficiency is indicated in many health conditions, so blood levels are worth checking both in the height of summer and the depths of winter, particularly in the elderly, dark skinned people and those with chronic health conditions.

O2B Vitamin D3 is also known as cholecalciferol and the “happy hormone”, it is fat-soluble and is found mostly in the skin of animals and in some plants. Made in humans by the skin by exposure to sunlight through conversion of a cholesterol-based precursor, D3 is needed to regulate calcium levels in soft tissue, optimize calcium absorption from our diets and act as a regulator of bone mineralization.

Supplementation of O2B Vitamin D3 supports normal bone health, especially in the elderly, dark skinned people, users of sunscreens and individuals with gastrointestinal conditions where exposure to sunshine and absorption of nutrients from diet can be impaired.

As a powerful gene regulator supporting the up-regulation of nearly 300 different genes to control 80 different metabolic processes, Vitamin D also supports the immune system in reducing the risk of developing many serious health conditions and building immune competency to help fight off infections. Studies have shown a protective effect against COVID in those who had adequate D3 levels compared to those with deficiencies.
