Product Insights
Vitamin D3 1000 IU is a supplement that delivers 25 µg (1000 IU) of cholecalciferol per tablet, marketed by Kirkland Signature and sold at Costco, manufactured in Canada. It is labeled gluten‑free, lactose‑free and contains several synthetic excipients such as croscarmellose sodium, dicalcium phosphate, hydroxypropyl cellulose, hypromellose, microcrystalline cellulose and vegetable magnesium stearate, resulting in a NOVA 4 classification. While it provides a complete daily dose of vitamin D with virtually no calories, sugar, fat or salt, the absence of a Nutri‑Score and the presence of multiple additives may be seen as drawbacks for clean‑label consumers.
