Source Naturals Vitamin D‑3 50 µg (2,000 IU) supplement, offered in capsule and softgel formats across multiple pack sizes.
+ Provides a standard 50 µg dose of vitamin D3 per unit, with all doses clearly disclosed. + Includes dibasic calcium phosphate in the capsule version and rice bran oil in the softgel version – ingredients not commonly found in competing vitamin D products. + Contains common allergens (egg, gluten, soya) across the range. - Both formats list artificial colour among the additives, which some users may wish to avoid. - The softgel variant adds several additional excipients (glycerine, starch, salt, preservatives) not present in the capsule form.
The family delivers a consistent 50 µg vitamin D3 dose, supporting bone health and immune function, while maintaining full dose transparency. Its formulation stands out by incorporating dibasic calcium phosphate in the capsule and rice bran oil in the softgel, both relatively rare among vitamin D supplements. However, both variants include artificial colour, and the softgel adds extra excipients, which may be a consideration for those seeking minimal additive profiles. Larger pack sizes are generally positioned in a budget tier, offering better value per unit compared with smaller packs.
