It’s made in Canada. How Pure Lab Bioactive B Complex Compares Pure Lab Bioactive B vs Standard B-Complex Pure Lab Bioactive B (this product): Active, body-ready forms (methylcobalamin, L-5-MTHF, P5P) plus slow-release delivery. Standard B-Complex: Often uses non-active forms (cyanocobalamin, folic acid) that require conversion. A fit if cost is the priority, though active forms are preferable. Pure Lab Bioactive B vs CanPrev Synergy B Pure Lab Bioactive B (this product): Bioactive B-complex with slow-release and benfotiamine, focused on comprehensive B coverage. CanPrev Synergy B: Active-form B-complex with added L-theanine for calm focus. A fit if you want the calming L-theanine component. See CanPrev Synergy B. Pure Lab Bioactive B vs B12 Alone Pure Lab Bioactive B (this product): The full range of B vitamins together for broad support. B12 Alone: Focused B12 for those who specifically need it (vegans, older adults). A fit if B12 is your only target. See Vitacheck B12. Methylated vs Non-Methylated B Vitamins B vitamins come in different forms, and the active forms can be used directly: Bioactive / methylated forms (this product): The body-ready forms — methylcobalamin (B12), L-5-MTHF (folate), P5P (B6), riboflavin-5-phosphate (B2). Your body uses them directly without conversion. Standard / non-active forms: Cyanocobalamin (B12), folic acid (folate), standard pyridoxine (B6). These must be converted to the active forms before use. Why active forms matter: A significant share of people have genetic variations (like MTHFR) that make converting folic acid to active folate less efficient. Active forms bypass this conversion step. Benfotiamine: A fat-soluble form of thiamine (B1) that's well-absorbed — included here as part of the bioactive approach. Why slow-release: B vitamins are water-soluble and not stored long-term, so a slow-release design helps maintain steadier availability through the day rather than a single quick spike. B vitamins work together: The B vitamins function as a team in energy metabolism and nervous system support, which is why a complete B-complex is often preferred over single Bs (unless you have a specific need). How To Use Adults: Take 1 capsule daily, ideally earlier in the day (B vitamins support energy and can be mildly stimulating, so taking them late may affect sleep for some), or as directed by your healthcare practitioner. Can be taken with or without food. Talk to a healthcare practitioner before use if you take medications, have a medical condition, or are using other supplements containing B vitamins or niacin. B vitamins can turn urine bright yellow — harmless and normal. High-dose niacin can cause temporary flushing in some people. Frequently Asked Questions ➕ What makes it "bioactive"? It uses the active, body-ready forms of the B vitamins — methylcobalamin (B12), L-5-MTHF (folate), P5P (B6), riboflavin-5-phosphate (B2), and benfotiamine (B1). These can be used directly by the body without the conversion step that standard forms require. ➕ Why does the active form matter? A significant share of people have genetic variations (like MTHFR) that make converting folic acid to active folate less efficient. Active, methylated forms bypass this conversion step, so your body can use them regardless of conversion ability. It's why many people prefer bioactive B-complexes. ➕ What does slow-release do? B vitamins are water-soluble and not stored long-term. A slow-release design helps maintain steadier B-vitamin availability through the day, rather than a single quick spike that's used and excreted. It supports more sustained levels. ➕ How is it different from CanPrev Synergy B? Both are active-form B-complexes. Pure Lab focuses on comprehensive bioactive B coverage with slow-release and benfotiamine. CanPrev Synergy B adds L-theanine for calm focus. Choose Pure Lab for comprehensive B support, or Synergy B if you want the calming L-theanine component. ➕ When should I take it? Earlier in the day is best — B vitamins support energy and can be mildly stimulating, so taking them late may affect sleep for some people. Can be taken with or without food. The slow-release design supports steady levels through the day. ➕ Why is my urine bright yellow? That's the riboflavin (B2) and it's completely harmless and normal. B vitamins are water-soluble, so excess is excreted in urine, turning it bright yellow. It's simply a sign your body took what it needed and passed the rest.
