Life Extension Vitamin B6 250 mg
Brand: Life Extension · Form: CAPSULE [E0159] On Market
Our assessment
The evidence shows that this product contains 250 mg of vitamin B6 per serving, which is an amount far exceeding the recommended daily allowance. Our assessment is that such a high dose is not appropriate for general health maintenance and carries known risks of nerve toxicity. For most purposes, you should avoid this dosage unless under specific medical supervision [NIH ODS].
How it works
Vitamin B6 is a coenzyme that plays a critical role in over 100 enzyme reactions in your body, primarily involved in protein metabolism, cognitive development, and the formation of neurotransmitters. However, the specific mechanism for this high-dose formulation is not supported by the data provided for general use [NIH ODS]. Data on the specific ingredient "Vitamin B6" at this dosage is not available in the provided materials.
Safety profile
Data not available for the specific side effects and report counts for this exact product. The FDA adverse events database shows a total of 592,059 reports across all supplements, but individual ingredient data is not provided. High doses of vitamin B6 (typically over 100 mg daily) are known to cause sensory neuropathy, which can lead to numbness and difficulty walking. This specific risk is not detailed in the provided data, but the 250 mg dose is a known concern [FDA data].
Our recommendation
We strongly recommend you do not take this supplement without direct guidance from your physician. The 250 mg dose is significantly above the safe upper limit for long-term use. For general health, a standard multivitamin or a B-complex with lower amounts of B6 is a safer and more evidence-based choice. Data on the specific benefits of this exact product is not available [NIH ODS].
