Why does the form of B Vitamins matter?

Not all B-vitamin supplements are created equal. Many standard B-complex products use the cheapest forms of each B vitamin — forms that your body still needs to convert before it can actually use them. For some people, this conversion works well. But for others — particularly those with a common genetic variation called MTHFR (which affects a significant portion of the population) — this conversion is less efficient, meaning they may not be getting the full benefit from their supplement even when they take it every day. Life Extension’s BioActive B-Complex takes a different approach: it uses the “ready-to-use” forms of the key B vitamins — the forms your body can put to work immediately, without any conversion needed. Think of it like the difference between receiving a flat-pack piece of furniture versus one that’s already assembled. The folate in this formula is the active form (L-5-MTHF) that works even for those with the MTHFR variation. The B12 is methylcobalamin — the form your brain and nervous system actually use. The B6 and B2 are also provided in their active coenzyme forms for maximum uptake. The result is a B-complex that works harder for more people.

Who is this for?

• Those who want to make sure their B vitamins are actually being absorbed and used

• Anyone wanting to support a healthy heart and normal homocysteine levels
• Those wanting to support mood, memory, and mental clarity
• People wanting healthy skin, hair, and nails
• Vegetarians and vegans — particularly important for B12
