SISU Ester-C 1000mg Details

High-potency SISU Ester-C® 1000mg tablets help to strengthen your immune system, alleviate allergy symptoms, encourage the growth and repair of body tissues and maintain the integrity of bones, gums, and teeth with fewer pills. Enhanced with citrus bioflavonoids for superior absorption and rutin for its anti-inflammatory properties, this formula also contains naturally rich sources of vitamin C in acerola cherry extract and a citrus fruit blend.

Vitamin C is a water-soluble antioxidant and one of the best researched nutrients. Vitamin C is found in fruits and vegetables, but it is easily destroyed by heat, cooking, processing, and storage, and rapidly eliminated from our system in the urine. Inadequate levels of vitamin C may be seen in cases of physical and mental stress, older people and those with chronic conditions including cardiovascular disease, asthma, arthritis, age-related eye disease, and certain cancers. Vitamin C is best known for strengthening the immune system by supporting and improving white blood cell function. It is also essential for the proper formation of collagen, a building block of many tissues and a crucial component in skin rejuvenation. Vitamin C also helps to reduce histamine release in the body, thereby alleviating allergy symptoms. There are numerous forms of vitamin C with ascorbic acid being the most basic. People wanting a clinically proven form that is easier on the system than ascorbic acid may choose a form like Ester-C® brand calcium ascorbate.

  • Added rutin, an antioxidant bioflavonoid used for its anti-inflammatory properties and to strengthen capillaries
  • Enhanced with acerola cherry extract and citrus fruit blend, naturally rich sources of vitamin C
  • Enhanced with antioxidant bioflavonoids from citrus fruits for superior absorption

Sisu Ester-C 1000mg is made from calcium ascorbate formulated through a patented process so that it neutralizes intestinal acids and can therefore be absorbed without discomfort. It also contains a form of calcium, which enhances absorption. Also, Ester-C can be good for your teeth. In addition to intestinal distress, the acidity caused by ascorbic acid can contribute to tooth decay. But studies show that Ester-C can actually fight tooth decay.
