* Required Fields

SISU Ester-C Supreme Powder

May help to support a healthy immune system.*

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, and therefore 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 reported 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 should 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.*
  • Enhanced with quercetin, a bioflavonoid and powerful antioxidant with anti-inflammatory and antihistamine properties.*
  • Added bioflavonoids from berry fruits for superior vitamin C absorption.*
  • Arabinogalactan is a type of polysaccharide that offers additional immune support during stressful times and the cold and flu season.*
  • Ester-C® has a clinically-proven, higher bioavailability and retention rate than other forms of vitamin C.*
  • Formulated with citrus-free ingredients for people wishing to avoid citrus.*


  • Formulated with no non-medicinal ingredients.*
  • Powder form for flexible dosing (people can personalize the amount they take at one time).*
  • Suitable for vegans.*
  • Contains no ingredients that are a source of gluten.*
  • Good Manufacturing Practices standards.*
  • Tested for guaranteed purity and potency.*
  • NPN approved.*
