Many companies: Many companies make good vitamin d3 products -- there is no one "best." the seal "usp verified ingredients" on the label may help. Or if the company uses "gmp" standards. Depending on your preferences, you may want a source free of gluten, dairy, etc. Labels will tell you that information also. Consumerlab shares some reliable info on specific products: http://www.Consumerlab.Com.
