So far so good. Hasn’t been quite long enough to tell, but pleased to find a methylated vitamin B at Sam’s.

Members Mark vitamins are high quality. Their Vitamin B12 is superior to store brands and better priced.

Great high Potency Vitamin B12. Have used for several years & can't find a better product for the price anywhere else.

I’ve been taking this brand of B12 for years and love it. The methylcobalamin is good for my energy and nerve support.

I love how these dissolve under your tongue and especially the taste. I feel really good and will continue to buy this product.

It’s a good product for getting the right amount of B-12. It’s reasonably priced. It’s easier than giving yourself a shot. I would recommend it.

I paid double this price for half the quantity. So this was a no brainer. Quantity & Quality is always great.

Excellent service and very convenient to order. My only con is that I thought by looking at the label that the tablets were scored.

Very potent (and tasty!) form of B12. They really do work, and I’ve had the lab work that proves it. Good quality B12!

Sam's Club is one of the few places you can get this kind of Vitamin B12. If available elsewhere, it costs more for a lower dose.
