VegD3® is derived from natural algae, making it 100% plant-based and vegan, while most D3 supplements come from animal sources like lanolin (sheep's wool). Despite being plant-based, VegD3® is chemically identical to animal-origin cholecalciferol, ensuring the same optimal absorption and efficacy.

Whole food vitamin D3 contains naturally occurring cofactors, enzymes, coenzymes, antioxidants, and trace elements from concentrated fruits and vegetables that enhance bioavailability and cellular function. Synthetic isolated vitamins lack these beneficial cofactors, making whole food forms more effective and better recognized by your body.

Each serving provides a therapeutic dose of vitamin D3 from organic algae. Check the supplement facts panel on the label for the exact IU (International Units) per serving. Consult your healthcare provider to determine the optimal dosage for your individual needs.

Absolutely! This formula is USDA Organic certified, Vegan certified, Kosher certified, and free of chemicals, pesticides, fillers, and common allergens. It's perfect for vegans, vegetarians, those with dietary restrictions, or anyone seeking the cleanest, most premium vitamin D3 available.
