Product Description

ENDUR-B® Complex Sustained Release (SR) is ideal for healthy adults – especially dieters, athletes, mature adults, and people interested in heart health – to ensure an optimal intake of B vitamins or fuel higher metabolic demands.*

ENDUR-B® Complex SR features high-potency B vitamins in a proprietary vegetable-based wax matrix specifically designed to release B vitamins gradually over a 5 to 7 hour period for optimal absorption and tissue retention.*

Your body relies on B vitamins for a wide range of functions. In particular, Vitamin B6, folic acid, and vitamin B12 provide heart health benefits by helping to maintain a healthy homocysteine level in the normal range. Yet unlike fat-soluble vitamins, water-soluble B vitamins are not stored in body tissues and require daily replenishment.*

  • Gluten-free
  • Vegan/Vegetarian
  • Free of common allergens (milk, egg, fish, shellfish, tree nuts, peanuts, wheat and soy)
  • Free of other allergens (corn, yeast)
  • Convenient once daily serving
