Ester-C 1000 mg from Vitals

The Vitals dietary supplement contains Ester-C and citrus bioflavonoids. The patented Ester-C is a buffered vitamin C , which means that the ascorbic acid is combined with a mineral (calcium). This form is also called calcium ascorbate.

What are the benefits of Ester-C?

Vitamin Ester-C is pH-neutral and therefore a non-acidic form of vitamin C. For this reason, this form is stomach-friendly and particularly suitable for sensitive people.

Another unique feature is that, unlike pure ascorbic acid, Ester-C contains vitamin C metabolites . Once vitamin C is absorbed into the body, it is converted into certain metabolites (intermediate or final products). The most important metabolite appears to be threonic acid . Ester-C has already been partially converted, so certain natural metabolites such as threonic acid are already present. Threonic acid and the other vitamin C metabolites can improve the absorption and utilization of vitamin C in the body.

Usefully supplemented with bioflavonoids

Bioflavonoids are water-soluble substances that occur together with vitamin C, especially in fresh fruit and vegetables. Bioflavonoids are considered synergists of vitamin C and can promote its bioavailability.

Vitamin C has numerous functions

The human body cannot produce vitamin C itself. It is therefore dependent on food sources for its supply. One tablet of Ester-C contains 1000 mg of Ester-C, of ​​which 790 mg is vitamin C.

Vitamin C increases iron absorption, helps protect cells from oxidative stress and contributes to:

  • normal function of the immune system , in general and during and after intense physical activity
  • normal collagen formation for normal function of blood vessels, bones, cartilage, skin and teeth
  • normal energy metabolism
  • normal functioning of the nervous system
  • normal psychological function
  • Reduction of tiredness and fatigue

The intake and dosage of Ester-C 1000 mg

Adults take 1 tablet daily with a glass of liquid with a meal, or as recommended by a healthcare professional.

Thanks to a notch , the tablets can be dosed as needed. This means that the tablets can easily be halved, meaning that even smaller daily doses can be given without any problem. The dosage can be adjusted to suit body weight, individual metabolism and physical condition.

Please note: When the tissues are saturated with vitamin C, soft stools or even diarrhea may occur. This is harmless and disappears when the dosage is reduced.
