Tag: Vitamin d effectiveness

A 2011 study published in the *Journal of Clinical Endocrinology & Metabolism* found that vitamin D3 is approximately 87% more potent than vitamin D2 at raising serum concentrations. This critical finding helps clarify the common confusion over which is more effective, vitamin D or D3, especially for individuals considering supplementation.

According to the NIH, an estimated 1 billion people worldwide have inadequate vitamin D levels. As interest in plant-based diets grows, many are asking: is vegan D3 as good as regular D3? The answer lies in understanding their identical chemical structure, despite their different origins.

An estimated 42% of adults in the United States are deficient in vitamin D, a vital nutrient for bone health, immune function, and more. For many, oral supplementation is a simple and accessible way to address this widespread issue, and scientific evidence confirms its efficacy.
