🔍🌞 Vitamin D2 or D3 – What Really Matters?
Vitamin D is commonly divided into two main forms: vitamin D2 (ergocalciferol), derived from plant and microbial sources, and vitamin D3 (cholecalciferol), primarily sourced from animals. Once absorbed, both D2 and D3 are converted into calcitriol – the biologically active form of vitamin D – which then circulates in the body to support essential physiological functions.
Recent scientific studies, along with official publications from the U.S. FDA, NIH, and the European EFSA, confirm that vitamin D2 and D3 have comparable bioavailability when properly absorbed.
While most vitamin D3 on the market is produced from lanolin (sheep wool grease) through complex refining and chemical synthesis processes, vitamin D2 can be obtained from a natural, fully vegan yeast source.
🌞 Produced by Lallemand, a global leader in yeast-based solutions, Lalmin® Vita D® is a naturally sourced vitamin D2 derived from Saccharomyces cerevisiae. Through controlled exposure to sunlight or UV light, the yeast’s naturally occurring ergosterol is converted into vitamin D2, closely mimicking how the human body synthesizes vitamin D when skin is exposed to sunlight.
That is why Lalmin® Vita D® is often referred to as “Sunshine Yeast Vitamin D2.”
Notably, Lalmin® Vita D® is currently the only vegan vitamin D2 source with a recognized safety dossier approved for use in infant nutrition products, providing strong evidence of its safety, natural origin, and reliability.
