B-COMPLEX REPORT

Labdoor analyzed 6 of the best-selling B-Complex supplements in the United States for B-vitamin content and heavy metal (arsenic, cadmium, lead, mercury) contamination.

All B-Complex supplements in this batch analysis claimed thiamin (vitamin B1), riboflavin (vitamin B2), niacin (vitamin B3), pantothenic acid (vitamin B5), vitamin B6, biotin (vitamin B7), folate or folic acid (vitamin B9), and vitamin B12.

Overall, measured B-vitamin values deviated from label claims by an average of 29%. In most cases (66% of the time), products had more of each B-vitamin than they claimed.

Measured B-vitamin values ranged from -99% to +258% vs. their respective label claims, deviating from label claims by an average of 29%. In most cases, products had more of each B-vitamin than they claimed. Of the B-vitamins, folate (vitamin B9) exhibited the highest label claim deviation; measured values deviated from label claims by an average of 44%. While niacinamide, pyridoxine hcl and riboflavin all deviated from label claims by an average of less than 6%.

All products passed heavy metal screens. This means that each product's heavy metal recordings per serving passed USP’s standards. Analytical Chemistry Methods: CE (vitamins B1, B2, B3, B5, B6), Gravimetry (biotin), ICP-OES (vitamin B9), LC-FLD (vitamin B12), ICP-MS (arsenic, cadmium, lead, mercury).
