Twinlab® Calcium Citrate Caps Dietary Supplement Capsules - 150. Easily digested. Quick acting. Plus magnesium. Calcium Citrate is an easily absorbed, soluble and chelated form of calcium preferred by many health and nutritional experts. It is less likely to cause constipation - a very real and uncomfortable problem with certain calcium supplements. Twinlab Calcium Citrate Caps plus magnesium go to work quickly in the stomach. Calcium and magnesium tablets, on the other hand, need binders to hold them together. Naturally, these binders may resist dissolving, so it is possible for a calcium plus magnesium tablet to pass through the digestive tract without being completely absorbed. Twinlab calcium citrate caps plus magnesium are easier to swallow and assimilate. No tablet binders, coatings or colorings. Free of the most common allergens such as fish, corn, soy, yeast, wheat, barley, lactose (milk sugar) and all milk and egg products. No added flavorings, sugars, salt, artificial sweeteners, preservatives or salicylates. Packaged in a glass bottle for maximum stability, quality and freshness. 1-800-645-5626.
