Full Description


Ester-C® 1400mg is an advanced, patented formulation providing a 1000mg dose of vitamin C, proven to deliver higher amounts of vitamin C into cells, with faster absorption and superior duration of action. Ester-C’s absorption into immune cells is 10x greater than standard vitamin C, and it's also unique in offering 24-hour nutrient coverage in one daily dose. Though Ester-C is especially beneficial for boosting the immune system because of its unusually high uptake and duration of action in immune cells, its strong bioavailability makes it the ideal supplement to support vitamin C levels for a range of health benefits. Vitamin C’s many roles in the body include protecting against oxidative stress caused by free radicals, increasing iron absorption, supporting the nervous system, reducing fatigue, and supporting cartilage production, as well as skin, gums and teeth and blood vessel tissue. Unlike ascorbic acid, Ester-C won’t irritate the stomach as it’s non-acidic. It’s suitable for vegans and free from dairy, gluten, lactose, soya and yeast.
