Product Description
Every carbohydrate you fuel with, every gram of protein you eat for recovery, and every fat you burn on a long ride — your body needs B vitamins to convert all of it into usable energy. When B levels drop from training stress, sweat loss, and the sheer metabolic demand of endurance work, you feel it: flat energy, sluggish recovery, and that foggy feeling mid-afternoon when you should be sharp.
Pure Encapsulations B-Complex Plus delivers the full spectrum of B vitamins in their activated, bioavailable forms — so your body can actually use them without extra conversion steps.
Activated Forms for Superior Absorption – Most B-complex supplements use cheap, inactive forms that your body has to convert before it can use them. B-Complex Plus includes methylcobalamin (active B12), riboflavin 5'-phosphate (active B2), pyridoxal 5'-phosphate (active B6), and Metafolin® L-5-MTHF — the naturally occurring, bioactive form of folate. This matters because up to 40% of people have genetic variations that make converting standard folic acid inefficient.
Complete Energy Metabolism Support – B vitamins are essential coenzymes in your mitochondria — the engines that power every training session. Thiamin (B1) and pantothenic acid (B5) drive carbohydrate metabolism. B6 supports amino acid metabolism and glycogen breakdown. B12 is critical for red blood cell production, which directly impacts oxygen delivery to working muscles. Together, they keep your energy production running efficiently from warmup to cooldown.
Nervous System and Cognitive Support – Beyond energy, B vitamins support healthy neurotransmitter production, methylation, and nerve function. Healthy methylation is vital for DNA repair, hormone production, and the cognitive clarity that separates a focused athlete from a distracted one. This formula supports cardiovascular and neurological health alongside daily performance.
This is a clinical-grade formula with only two other ingredients: a vegetarian capsule and ascorbyl palmitate. No fillers, no binders, no common allergens.
How to Use B-Complex Plus
Daily Dose: Take 1 capsule, 1–2 times daily, with meals.
Pro Tip: B vitamins are water-soluble — your body excretes what it doesn't need — so consistent daily dosing is more important than loading up. Don't be alarmed if your urine turns bright yellow; that's normal B2 excretion.
Athletes running high training volumes burn through B vitamins faster than sedentary people. A daily activated B-complex ensures your energy metabolism, red blood cell production, and nervous system have the raw materials they need to keep up with your training.

Pure Encapsulations B-Complex Plus FAQ's
Everything you need to know before getting started.
Take 1 capsule with breakfast. B vitamins support energy metabolism, so morning dosing sets up your energy systems for the day. If taking 2 capsules daily, split between breakfast and lunch — avoid evening dosing as it can disrupt sleep in some athletes.
Yes — and it's especially important for them. B12 is found almost exclusively in animal foods, making deficiency common in plant-based athletes. B-Complex Plus delivers 400mcg of methylcobalamin B12 — the most bioavailable form available.
Yes. If you're also taking Daily Stress Formula — which includes its own B vitamins — consider dropping to 1 capsule of B-Complex Plus daily to avoid unnecessary overlap. For most athletes the combined doses are fine, but it's worth knowing.
Most athletes notice improved energy and mental clarity within 1–2 weeks, especially if they were depleted beforehand. Full cardiovascular and neurological benefits build with consistent daily use over 4–8 weeks.
