You take B vitamins every day. You still feel tired. The reason is almost always the same the B vitamins in most supplements are in synthetic, inactive forms that your body has to convert before it can use them. Folic acid has to become 5-MTHF. Cyanocobalamin has to become methylcobalamin. Pyridoxine has to become P5P. If anything in those conversion chains is suboptimal due to chronic stress, gut inflammation, a common genetic variant, the conversion doesn’t happen fully. And you absorb a fraction of what the label says you’re getting. iThrive Active B-Complex skips the conversion step entirely. Every B vitamin in this formula is already in its active, metabolically ready form. What goes in is what your cells use. What iThrive Active B-Complex may support: Energy metabolism — all 8 B vitamins participate in converting food to cellular energy (ATP) Mental clarity and focus — B vitamins are cofactors in neurotransmitter synthesis; deficiency is consistently linked to brain fog Stress response — B5, B6, and B12 are essential for the adrenal stress response; depleted rapidly under chronic stress Hormonal balance and PCOS — active folate supports methylation, Myo-Inositol aids insulin sensitivity and ovarian function Preconception and pregnancy — Quatrefolic® active folate is the clinically recommended form before and during conception Liver and cell membrane health — Phosphatidylcholine from sunflower lecithin supports liver fat metabolism and cell membrane integrity Mood balance — B6, B9, and B12 are required for serotonin, dopamine, and norepinephrine synthesis Hair, skin, and nails — D-Biotin (B7) supports keratin infrastructure; the active form bypasses absorption issues common with generic biotin The formula is built around what’s in it and what isn’t. No magnesium stearate. No silicon dioxide. No titanium dioxide. No artificial colours. No synthetic preservatives. No folic acid (the synthetic, inactive form). No cyanocobalamin (the cheap B12 form most brands use). Preserved naturally with rosemary extract used to protect the active B vitamins from oxidation during shelf life, without introducing synthetic antioxidants. The capsule shell is 100% HPMC vegetarian, clean, free from gelatin. Sunflower lecithin, not soy lecithin, so it’s suitable for anyone avoiding soy. How to use Take 1 capsule after each meal, up to 3 times daily or as suggested by your healthcare practitioner. Each capsule delivers 100% RDA of every B vitamin in its active form. Practical note: Starting with 1 capsule per day and increasing gradually is advisable for those new to active B vitamins, as higher doses can occasionally cause mild initial responses (vivid dreams, warm skin flush from niacin). These settle within a few days for most people. Can be taken alongside: iThrive Magnesium Bisglycinate (magnesium supports B vitamin activation), iThrive Vitamin D3+K2 (D3 metabolism requires B vitamins), and iThrive Marine Omega-3 (B12 and omega-3 work synergistically for brain and cardiovascular health).
