Sisu Ester-C Chewable 500mg

Vitamin C is a water-soluble antioxidant and one of the best researched nutrients.* Most mammals can produce vitamin C as they need it, but the human system evolved without this ability so we must ensure an adequate daily intake to stay healthy.* 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 referred to for strengthening the immune system by supporting and improving white blood cell function.* It is also essential for the proper formation of collagen, the 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.*

  • Ester-C is a unique, patented form of calcium ascorbate, which is made when ascorbic acid (regular vitamin C) is buffered with calcium using a water-based process*
  • The calcium in Ester-C provides part of your daily calcium requirements*
  • Ester-C contains active vitamin C metabolites including L-threonate, which enhance cellular absorption and retention*
  • Ester-C is the only form of vitamin C that has been proven to last up to 24 hours in the white blood cells of the immune system*
  • Less acidic and easier on the stomach than ascorbic acid*
  • Ester-C has a clinically proven higher bioavailability and retention rate than other forms of vitamin C*
  • Available in three natural flavours: orange, wildberry, and citrus punch.*


  • High-potency chewable tablets for those wanting to supply their vitamin needs with fewer pills.*
  • All natural flavours and sweeteners.*
  • Suitable for vegans.*
  • Contains no ingredients that are a source of gluten.*
  • Good Manufacturing Practices standards.*
  • Tested for guaranteed purity and potency.*
