B12 supplement

My husband needs B12 to supplement his restless leg symptoms. This is by far the best one he has used.

I know when missed in the morning

I depend on these in the morning. I like that the taste is not overpowering, but good. They dissolve easily. Hope Sam’s doesn’t stop carrying them.

Works great

I like to take one of these every morning. They help me feel more awake and energized. The flavor is good and I like that they’re dissolvable

Perfect choice

This is an exceptional choice. First, as vitamin B12 deficiency is too common, it provides a very high dose, something necessary for the many people who have difficulty absorbing B12, especially the elderly. And this is further improved by making it sublingual instead of in simple pill form. Secondly, it is in the form METHYLcobalamin, which is the active form of the vitamin, instead of the usual CYANOcobalamin, which is not. This is important because up to 30% of people have genetic problems adding the methyl group on to the B12. Lastly, it is a great price, a great value.

Works

B12 is destroyed by normal stomach acids. Using sublingual allows the B12 to be absorbed and used by the body.My lab values for my B12 levels support this. Found these several years ago and have been pleased with them. Pleasant flavor with no chalkiness or foul aftertaste.

Great bioavailability for this one …

My last lab reports my doc said are using a B12 supplements, why yes I am. One per night, no other supplements showed like this one. Bioavailability is good.

Member’s Mark Vitamin B12 Quick Dissolve Tablet...

I like to quick dissolve tabs and the chemistry level has raised on lab tests. It works.

Taste Great

Been using these for about 2 weeks. Taste is great. However, I havent noticed even an iota of increased energy. That being said, it may take more time.
