Seller: what is the difference between copper glycinate and copper bisglycinate?

Copper bisglycinate is the same as copper glycinate. Copper bisglycinate is the more accurate way to describe this compound, which is copper attached to two glycine molecules (bis = 2).

Are all sources of all ingredients, both inactive and active, 100% vegan or vegetarian or neither?

Copper Bisglycinate is not vegan because it contains leucine as one of its “Other Ingredients.” Leucine is derived from keratin, a type of animal protein.

Is this manufactured in the USA?

Thorne products are manufactured in South Carolina, USA.

Does this have USP certification?

USP verification is a service provided for a fee to nutritional supplement companies – mostly health-food store brand companies. Thorne has its own much more extensive verification process. Although all of Thorne's supplement ingredients comply with USP standards for the supplement industry, Thorne does not pay for the USP logo to be placed on their products. Thorne Research is 100-percent compliant with the Good Manufacturing Practice regulations enforced by the U.S. Food and Drug Administration for the nutritional supplement industry. Thorne’s internal standards for ingredient purchasing, product specifications, and manufacturing standards for finished products is unsurpassed. For example, Thorne products are approved for sale in Australia by the Therapeutic Goods Administration of the Government of Australia, a regulatory agency that does not distinguish between pharmaceutical products and nutritional supplement products. Thorne’s manufacturing facility is also regularly audited and certified by NSF International – which is necessary to have NSF Certified for Sport products.

Beneficial if not included in your multivitamin.

They are small ! Capsules and therefore easy to swallow. Copper is good for your body, but is highest in food one does not eat every day: Oysters, Lobsters, Organ meats dark chocolate and Shiitake mushrooms.

Seems to work for me!

I was low on copper in my bloodwork and was bruising easily and often. Haven’t done follow-up bloodwork but I’m not bruising like I was.
