Why choose Esterol Capsules?

Esterol is a highly absorbable vitamin C-bioflavonoid formula. Each capsule provides vitamin C as Ester-C™ which is a unique and advanced form of vitamin C. Ester-C™ is a patented, non-acidic mixture of ascorbic acid containing other clinically significant metabolites. This results in enhanced digestion, cellular uptake, and retention as well as utilization of vitamin C in the body. This unique delivery means it is a gentle form of vitamin C not associated with gastrointestinal upset. The bioflavonoids quercetin, rutin and proanthocyanidins (a polyphenol from grape pips) have demonstrated potent antioxidant activity protecting cells from oxidative stress and potentiate the antioxidant activity of vitamin C.

What is vitamin C needed for?

Vitamin C provides valuable and essential protection to all cells from oxidative stress and damage.

Our immune system needs adequate levels of vitamin C in order to function properly.

Vitamin C is a crucial component of all collagen formation in the body. Collagen is the main structural protein found in skin and other connective tissue in the body. As vitamin C supports collagen formation, it is important for the normal function of cartilage, blood vessels, bones, skin, gums and teeth.

Vitamin C supports the reduction of tiredness and fatigue as it is involved in normal energy-yielding metabolism.

Vitamin C is also essential for the proper functioning of our nervous system, and helps to maintain normal psychological function.

Vitamin C increases our absorption of iron.

Vitamin C also helps to ""recycle"" vitamin E - meaning it helps to preserve levels of vitamin E in cell membranes.

What are bioflavonoids and why are they important?

Bioflavonoids are a complex group of plant compounds that occur with vitamin C in nature. Bioflavonoids are also known to improve the uptake of vitamin C when added into supplements so it’s always best to take them together.
