Life Extension BioActive Folate & Vitamin B12
Brand: Life Extension · Form: CAPSULE [E0159]
Our assessment
The evidence shows that this supplement provides folate and vitamin B12, which are essential for healthy red blood cell formation and nerve function. However, the data provided does not include specific studies or efficacy data for this exact product formulation. Our assessment is that for most people, obtaining these nutrients from a balanced diet is sufficient, but supplementation can be beneficial for individuals with absorption issues or certain dietary restrictions [NIH ODS].
How it works
Think of folate and vitamin B12 as a team of helpers for your body's energy and repair systems. Folate supports DNA synthesis and cell division, while vitamin B12 is crucial for maintaining the protective coating around your nerves (the myelin sheath). Together, they work to convert food into usable energy and help prevent a type of anemia called megaloblastic anemia [NIH ODS].
Safety profile
Data not available for side effects specific to this product formulation. However, the FDA has received a total of 592,059 adverse event reports across all dietary supplements, though this number does not specify which events are linked to this product. In general, B vitamins are water-soluble, meaning excess amounts are typically excreted in urine, making them low-risk for most people. High doses of B12 are generally considered safe, but very high folate intake can mask a vitamin B12 deficiency [FDA data].
Our recommendation
Data not available to make a specific dosing recommendation for this product. If you are considering this supplement, we advise you to first check your vitamin B12 and folate levels with a blood test. This is especially important if you are over 50, follow a vegan or vegetarian diet, or have a condition that affects nutrient absorption. Always consult your healthcare provider before starting any new supplement regimen [NIH ODS].
