High-Potency D3 from Organic Lichen: OmniBiotics Organic Vitamin D3 delivers 5,000 IU (125 mcg) of cholecalciferol from certified organic lichen, a plant-based source of the same D3 the skin makes in sunlight, so vegans and vegetarians do not have to settle for D2.

The Sunshine Vitamin, Without the Guesswork: Vitamin D3 is critical for calcium absorption, immune regulation, mood, and bone health. Geographic location, sunscreen use, and indoor lifestyles mean many adults produce far less than they need for much of the year. A single 5,000 IU tablet each day makes up for the sun you're not getting.

OmniBiotics Organic Vitamin D3™: Physician-formulated and built for proactive health management. Whether you're supporting bone strength, immune function, or steady vitamin D levels through the winter, this high-potency organic formula delivers it in one plant-based tablet.

Pure. Potent. Professional Grade: OmniBiotics Organic Vitamin D3 is free of gluten, soy, dairy, GMOs, artificial ingredients, and preservatives, and comes in vegan tablets. Every batch is made in the USA in an NSF-certified cGMP facility.

OmniBiotics Organic Vitamin D3™ is for people who don't leave essential nutrition to chance and want 5,000 IU of organic, plant-based D3 in a single daily tablet.
