Make sure the B-complex, B vitamin, or "energy" supplement you take passed our test and is right for you!
Isn't your health worth it?
Our tests and quality ratings of B vitamin supplements, including B-complexes and energy drinks/shots, revealed problems with the quality of 7 out of 23 products selected for review. These products came up short on listed vitamins, containing only 31% to 87% of the claimed amounts, and/or contained far more ingredient than claimed, ranging from 182% to 230% of what was expected. Among B vitamin supplements, the most problematic were B complexes.
Testing also revealed the actual amounts of caffeine in the popular energy drinks/shots 5-Hour Energy, Monster Energy M-3, and Red Bull. Just a single small bottle of either of two of these products contained more than twice the caffeine you would expect from a regular cup of coffee. Following the serving suggestions of one product could lead you to ingest an extremely high amount of caffeine -- over 600 mg per day.
In this comprehensive report, you'll get quality ratings and reviews of 37 B vitamin supplements and fortified energy drinks: 23 products selected by and 14 others that passed voluntary certification testing. You'll also get information about two supplements similar to one that passed testing. Tested products include B-complexes, energy shots, and single-B vitamin supplements with thiamin, niacin, vitamin B-6, vitamin B-12, biotin, folate (folic acid), or pantothenic acid.
