Build your foundation for sustained endurance performance with BPN Endurance Essentials — the daily multivitamin formulated specifically for the demands of endurance training. When you're logging miles, hours on the bike, or long training sessions, your body depletes key micronutrients faster than the average lifestyle athlete. That's why we identified five core nutrients—Vitamin D3, Iron, Magnesium, Zinc and Vitamin K2—that tend to drop with consistent endurance work. One serving (3 capsules) with your first large meal provides these nutrients in effective doses to help support energy metabolism, healthy muscle contraction & relaxation, immune function and bone-vascular health. Manufactured in a GMP-certified facility and third-party tested to ensure what's on the label is what you get. The formula is gluten-free and NSF for Sport certified — giving you confidence in training, not just the claim. Whether you're prepping for a race, stacking supplements for training load or simply want to cover your core bases so you can recover smarter and train harder—Endurance Essentials is your go-to daily foundation. Suggested Use: Take three (3) capsules daily with your first large meal. Warnings: Consult your healthcare practitioner before use if pregnant or nursing, taking medication or have a medical condition. See label for full details.
