Is Kirkland Vitamin B12 Vegan? (I contacted them to find out)

I

I remember the first time I went to Costco after going vegan, and I spent about 15 minutes trying to look up whether or not the Kirkland vitamin B12 supplements were vegan friendly or not.

The packaging is unclear, but the fact that the B12 is in the form of methylcobalamin is a good sign, because that form is usually made in a lab.

I simply bought other supplements after giving up.

But that all changes today!

A few days ago, I finally contacted Costco’s customer service, and they got back to me with this reply:

The most important part is:

We have been informed that Item 1234728, Kirkland Vitamin B12 1,200 mcg, is a vegetarian product that does not contain animal ingredients. The methylcobalamin used in this product is synthetic.

So there’s our answer: Costco’s Kirkland vitamin B12 is confirmed to be vegan.

If you don’t have a Costco membership, you can find a good alternative from this list of the best vegan vitamin B12 supplements.

  • What about the stearic acid and magnesium stearate in the Kirkland B12 supplements? Is it cheaper for companies to mass produce vitamins using those compounds from animal sources or vegetable?

    Just wondering hope to hear anything soon.
