Are Costco Vitamins Good Quality? (the truth!)
Vitamin supplements are a great way to make up for what you don’t have in your diet. Depending on where you live and what you eat, you may be missing the essential ingredients for your body to heal and grow. Costco sells a variety of different vitamin supplements, mostly from the Kirkland Signature brand.
Judging the quality of vitamin supplements can be complicated. Vitamins come in many forms, some of which cannot be used by the body. In general, vitamins in natural foods are more bioavailable than isolated vitamins in supplements.
Are Costco Vitamins Good Quality?

The Costco website claims that Kirkland Signature brand vitamin supplements are designed and tested to meet or exceed the quality of other major supplement brands. However, the name is rather vague and doesn’t really tell us about the quality of their vitamins.
Costco’s supplements are not of high quality. While the USP has confirmed that Kirkland Signature vitamin supplements are pure and high-quality, many of these vitamins are synthetic and not as useful as the nutrients found in whole foods or other vitamin supplements.
The Kirkland Signature brand is by no means bad. Many basic vitamin supplements should meet daily needs. However, there are better options with higher bioavailability and fewer synthetic vitamins.
