Consumer advice
If you're deficient in B vitamins or have poor dietary intake, this product is legitimate and will help. However, you can get equivalent B vitamins for half the price from generic brands at any drugstore. Don't expect energy boosts if you're already well-nourished—B vitamins only work if you're actually deficient. Check the label for specific doses of each B vitamin before buying; the website doesn't clearly list them, which is a transparency issue.
