Thompson's Esterified C is a special, non-acidic form of Vitamin C that is pH neutral and highly absorbed by the body. Because Ester C is esterified, it is absorbed and used by the body significantly more effectively than ordinary Vitamin C.

Esterified C benefits the body in numerous ways. It boosts the immune system and enhances wound healing and repair. It protects against pollution, cigarette smoke, stress, and degenerative diseases. It also helps alleviate hayfever and allergies.

Unlike most animals, the human body cannot manufacture its own Vitamin C, so it must be replenished daily. The need for Vitamin C increases during periods of illness, stress, pregnancy, rapid growth, strenuous physical activity, following surgery or other trauma, and in those who smoke tobacco or consume alcohol.

Vitamin C's primary function is the manufacture of collagen, which is a crucial protein in the connective tissue, cartilage and tendons that hold the body together. So as well as a powerful immune booster, Vitamin C is useful for repairing wounds, preventing bruising and keeping gums healthy. 

Thompson’s Esterified C is very gentle on the stomach, making it ideal for those who take vitamin C in higher doses or over an extended period of time. Thompson’s Esterified C also provides valuable co-factors, bioflavonoids, Acerola and Rosehips to enhance the action of the complex.


Adults take 1 tablet daily (with food) or as professionally prescribed.


  • Use only as directed and always read the label.
  • Vitamin supplements should not replace a balanced diet.
  • If symptoms persist, consult your healthcare professional.
  • Not to be used in children under two years of age without medical advice.

Each Tablet Contains:

  • Esterified C (Calcium Ascorbate with metabolites) 1000mg
  • Acerola (Malpighia punicifolia) 100mg 
  • Bioflavonoids 20mg
  • Rosehips (Rosa canina) 30mg


There are a variety of health concerns that Thompson's products may be able to assist with, such as General Energy and Vitality, Healthy Aging, Stress Management and Children’s Health.

Junior Immunofort is a popular immune boosting formula that children love. It is packed full of vitamins, minerals and nutrients that may help support their overall health. 

Thompson's Grape Seed 19,000 tablets are rich with antioxidants like proanthocyanidins, which may protect cells from rogue free radical damage.
