Taken in combination with B-12 & Folic Acid which is a B vitamin as well. Good for cardiovascular health. I'll write more after I get my blood tested in a couple of months. Had 3 heart attacks in 2 weeks 6 years ago and don't take any medication at all. I just take NOW brand products such as Red Yeast Rice, Blueberry Extract, Vitamin C,B-12, B-6 with magnesium, & Folic Acid. So far everything checks out good. Great poducts!!!!!!! R. Nelson

Good value for money but the supplement would have been better if they had excluded the Magnesium Oxide which acts like a laxative.. I get loose stools if I take 3-4 of those a day.

It’s hard ro give a review of this product as my partner takes it as a preventative against Parkinsons disease. Having checked out side effects online, it seems to me that this stuff is pretty strong and could cause problems in some individuals. We are aware of potential symptoms (eg nerve pain) and will discontinue if he starts to show any signs. I tried one and it gave me a burst of energy, so I may take it occasionally. I wouldn’t take it regularly because I have severe chronic insomnia and b vitamins can make this worse. (This supplement is a form of b6).

I think these may be helping me with alertness. Slightly less fuzzy head these days... I take a B complex also

Short background: I am chronically depressed, socially anxious, with no motivation and very lethargic. I took these, hoping that it would give me more energy. Did nothing for me.

Like most medical remedies (prescription or OTC) you never really know how much or usually even IF they do anything for you.
