Methylated B Vitamins: B6 Caution & Benefits Review


I like the fact this is a methylated product, but be aware it does contain B6, which some people, (including myself) try to avoid.


Vitamin Basics & Tips


Methylated B vitamins, like those in this product, are pre-activated forms (e.g., methylcobalamin for B12 and methylfolate for B9) that bypass genetic mutations such as the MTHFR gene variant, which affects up to 40% of the population. These forms ensure better absorption for individuals with such polymorphisms.


Vitamin B6 (pyridoxine) supports nerve function, metabolism, and hemoglobin production. However, excessive intake (over 100 mg/day long-term) may cause neuropathy. While this product’s B6 dose likely falls within safe limits, some users avoid it due to sensitivities or pre-existing conditions requiring restricted intake.


When choosing B-complex supplements, check for methylated forms if you have absorption issues, and verify individual B-vitamin doses—especially B6 and B12—to align with dietary needs or medical advice. Always consult a healthcare provider before starting new supplements if you have specific health concerns.
