Douglas Laboratories B6 100 mg

Brand: Douglas Laboratories · Form: TABLET [E0155] On Market

Our assessment

The evidence shows that this product contains 100 mg of vitamin B6 per serving. For context, the recommended daily intake for most adults is significantly lower, and long-term use of high-dose B6 can lead to toxicity. We recommend you review your total B6 intake from all sources, including multivitamins, and consult with your healthcare provider before taking this supplement.

How it works

Vitamin B6, also known as pyridoxine, is a water-soluble vitamin that plays a key role in over 100 enzyme reactions in the body, primarily related to protein metabolism, red blood cell formation, and neurotransmitter synthesis. It helps your body convert food into energy and supports brain function. Data not available on the specific mechanism for this product’s dosage. [NIH ODS]

Safety profile

FDA received 592,059 adverse event reports across all dietary supplements. For vitamin B6 specifically, data on side effects from the provided FDA data is not available. However, it is important to note that taking high doses of vitamin B6 (typically over 100 mg daily) for extended periods can lead to sensory neuropathy, which may cause numbness and tingling in the hands and feet. [NIH ODS]

Our recommendation

Our recommendation: Unless you have a diagnosed deficiency or a specific medical reason under a doctor’s supervision, a 100 mg dose of vitamin B6 is very high and carries a risk of nerve damage over time. Start with a lower dose, and do not exceed the tolerable upper intake level of 100 mg per day from supplements without medical guidance. [NIH ODS]
