When I stopped taking these vitamins, I started feeling lethargic. I’ve been taking these Metabolic Maintenance B Vitamins for years. I will now continue taking them. No other B vitamins do the job.

We only just started taking these, but they seem pure and seem to have a strengthening effect - as B vitamins should, right?...So far, so good. I like this brand. I use quite a few of their other formulas. It came recommended by my acupuncturist who is also a Chinese Herb practitioner.
