Its B vitamins come already activated, and the slow-release capsule spreads them out over about 4 to 5 hours. Pure Lab's own suggestion — one capsule with breakfast and another at lunch — keeps levels up through the working day and keeps it out of your evening routine. A strong, clean, vegan pick from a Canadian brand. How Pure Lab BioActive B-Complex Compares Activated B-complex vs. regular B-complex Pure Lab notes that the B vitamins in food and most supplements need to be converted into biologically active forms before the body can fully use them. This formula supplies them already activated. Slow release vs. standard capsule The hypromellose SR in each capsule forms a gel on contact with digestive fluids and releases the vitamins gradually. Pure Lab says one dose maintains blood B vitamin levels for about 4 to 5 hours. Full B-complex vs. single B vitamins If you only need one nutrient, Pure Lab also offers BioActive Folic Acid 1mg (L-5-MTHF) and BioActive B6 50mg Slow Release (P-5-P). What Is a Bioactive B-Complex? B vitamins are water-soluble nutrients that work together in energy metabolism "Bioactive" means the vitamin is supplied in the form the body uses — for example methylcobalamin for B12 and L-5-MTHF for folate In this formula, B9 and B12 are methylated, and B2 and B6 are phosphorylated Riboflavin (B2) and riboflavin-5-phosphate can turn urine bright yellow — this is normal and harmless Recommended Purpose Balanced B-vitamins in their active form help metabolize carbohydrates, proteins and fats for energy, tissue support and red blood cell formation How To Use Pure Lab recommends 1 capsule with food at the start of your day and another 1 at lunch time Label directions: adults, take 1 capsule once or twice a day with food, or as directed by your health practitioner Take with food to reduce the chance of stomach discomfort, preferably no later than the second meal of the day Consult a health care practitioner for use beyond 8 weeks Ingredients (per Vegi-Cap) Vitamin B1 (benfotiamine) 50 mg Vitamin B2 (riboflavin-5-phosphate sodium) 25 mg Vitamin B3 (inositol hexanicotinate) 165 mg Vitamin B5 (calcium-D-pantothenate) 200 mg Vitamin B6 (pyridoxal-5-phosphate) 40 mg Vitamin B12 (methylcobalamin) 500 mcg Folate (calcium L-5-MTHF) 400 mcg Biotin 250 mcg Choline Included — see bottle label for amount Non-medicinal ingredients: vegetarian capsule, hypromellose SR agent, magnesium stearate (veg source). Frequently Asked Questions ➕ Are the B vitamins methylated? All of the B vitamins are in their activated form. They are either methylated (B9 and B12) or phosphorylated (B2 and B6). ➕ How long does one capsule last? Pure Lab says one dose maintains blood B vitamin levels for about 4 to 5 hours. The slow release comes from hypromellose SR, a fibre derived from poplar or birch tree pulp that forms a gel on contact with digestive fluids. ➕ When should I take it? Pure Lab recommends 1 capsule with food at the start of your day and another at lunch time. Take it no later than the second meal of the day. ➕ Why is my urine bright yellow? It's normal for urine to turn bright yellow with supplements that contain vitamin B2 (riboflavin) or its active form, riboflavin-5-phosphate. It's harmless. ➕ Is it vegan? Yes. It contains no animal-derived ingredients, and is free of gluten, wheat, sugar, milk, yeast, egg, shellfish, soy and corn. ➕ Is it made in Canada? Yes.
