Overview
['American Standard Supplements builds this formula around a two nutrient pairing, combining 5000 IU (125 mcg) of vitamin D3 with 200 mcg of vitamin K2 as MK7 in each capsule. At 120 capsules per bottle, it is marketed as a 120 day supply, and the formula is labeled gluten free and non-GMO.', 'Priced at about 19 dollars, this positions itself a step above single ingredient vitamin D3 products, reflecting the added K2 component. The maker markets the combination for general immune support rather than any specific medical outcome.', 'The product carries a 4.7 star rating from roughly 1,300 reviews, with an estimated 700 units purchased in the past month. That combination of a high average score and consistent recent demand is a reasonable signal of buyer satisfaction, though it is not a substitute for professional guidance on what supplement combination is right for you.']
