Promix B12
You're crushing workouts, stacking miles, and logging serious training hours. But if you're plant-based, over-training, or over the age of 40, there's a silent performance limiter you might not even know about: B12 deficiency. Your body can't make this vitamin, and most athletes don't realize they're running on empty until fatigue becomes chronic.
Promix B12 delivers 1000mcg of methylcobalamin—the active form your body actually uses—to keep your red blood cells pumping oxygen and your energy production firing.
The Power of Promix B12
B12 plays a critical role in red blood cell formation, which directly impacts how much oxygen your muscles get during training. Studies show optimal B12 levels between 400-700 pg/mL correlate with better hemoglobin production and oxygen transport. Below that range, even subclinical deficiency can tank your endurance and leave you dragging through workouts.
A Better B12 – Most B12 supplements use cyanocobalamin, a synthetic form your body has to convert before it can use it. Promix skips that step entirely with methylcobalamin, the exact form found in animal foods. It's immediately bioavailable, crosses the blood-brain barrier faster, and stays in your tissues longer.
Gut-Friendly Formula – Unlike synthetic B12 that can disrupt your microbiome, methylcobalamin supports healthy gut bacteria. When your gut is happy, nutrient absorption improves across the board—not just B12.
How to Take Promix B12
Daily Dose: Take one capsule daily with food. Vegan and vegetarian athletes should consider this non-negotiable. Athletes over 50 or anyone on calorie-restricted diets will also benefit from consistent supplementation.
Pro Tip: Don't take B12 with vitamin C supplements or citrus juice—vitamin C can degrade B12 before your body absorbs it. Space them out by a few hours for maximum benefit.
