Product Description

ENDUR-C® 500mg with Rose Hips (Sustained Release) is ideal for adults who want to fortify the body’s antioxidant defenses and promote optimal immune, skin and nerve health. People interested in healthy blood vessel function and optimal blood flow can also experience benefits.*

ENDUR-C® combines high-potency vitamin C with a unique sustained-release tablet delivery, resulting in a slow and steady release of ascorbic acid over 5 to 7 hours. By releasing small amounts of vitamin C at a time as the tablet travels through the intestine,

 ENDUR-C® allows your body to slowly absorb vitamin C. In this way, it not only helps maintain optimal blood and tissue levels, but avoids excess loss in the urine that is typical of regular forms of high-dose vitamin C.

ENDUR-C® helps minimize digestive upset that some people experience with regular forms of vitamin C.*

ENDUR-C® exerts its antioxidant effect in two ways. Throughout your body, it helps neutralize free radicals that can harm cells, including the endothelial cells that line your blood vessels. These cells play a key role in the ability of blood vessels to relax and promote optimal blood flow. In the blood, it helps recycle and reactivate another antioxidant, vitamin E.*

ENDUR-C® is available in two strengths: 500 mg and 1000 mg.

• Easy-to-swallow tablets
• No salt, sugar, starch, preservatives, artificial colors or flavorings
• Gluten-free
• Vegan/Vegetarian
• Free of common allergens (milk, egg, fish, shellfish, tree nuts, peanuts, wheat and soy)
