Isn't your health worth it?

Which are the best B-complexes and single vitamins? Our tests and quality ratings of B vitamin supplements, including B-complexes and energy drinks/shots, revealed problems with the quality of 6 out of 30 products selected for review. Among B vitamin supplements, the most problematic were B complexes. This new report shows which products passed or failed independent testing, how they compare on dosage and ingredients, and which provide the best value.
 
Testing also revealed the actual amounts of caffeine in popular energy drinks/shots/squirts. Just a single small bottle of one of these contained more than twice the caffeine you would expect from a regular cup of coffee. Following the serving suggestions for some may cause you to ingest greater amounts of B vitamins than you would normally want.

In this comprehensive report, you'll get quality ratings and reviews of 41 B vitamin supplements and fortified energy drinks: 30 products selected by ConsumerLab.com and 11 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/drinks/squirts, and single-B vitamin supplements with thiamin, niacin, vitamin B-6, vitamin B-12, biotin, folate (folic acid), or pantothenic acid.


In this comprehensive report, you'll discover:
    • Which B vitamin supplements and energy drinks failed testing and which passed
    • Cost comparisons and quality ratings of B vitamin supplements and energy drinks
    • Information on what B vitamin supplements and energy drinks can and cannot do for you -- some may reduce memory decline!
