Kirkland Sigature is the name of the manufacturer for these vitamins. No official website currently exists for Kirkland Signature products. Which leaves us looking at secondary sources for information on Kirkland Signatureâs products. Further, the company does not specialize in dietary supplements ... but produces numerous types of products. Which begs the question --- are these multis really that good?
Generally, the best supplements come from companies that formulate, manufacture and retail only supplementsânot from the companies that also make houswares and home applicances. You'd be best to find a multivitamin with low-to-moderate doses of vitamins and minderatls that's been verified by the United States Pharmacopoeia (USP). They've set the standard for the drug industry for the past 150+ years.
The only thing I'm concerned about the particular D3 vitamins I just purchased is that even though that the label states that that there are no artificial colors, ingredients, preservatives, etc., it does contain soybean oil and corn oil. Unless these two ingredients are non-GMO, I will be risking my health with such crap because most corn and soy are in fact GMO. Also, it contains gelatin which may be derived from pork. Ughhh!
