Vitamin C - the classic immune-system support
Vitamin C is primarily known for its effect on the immune system. However, vitamin C can do much more and is involved in many other processes in the body. Through its role in collagen formation, the water-soluble vitamin supports the normal functioning of the blood vessels. Furthermore, it is important for our antioxidative defence system: It contributes to protecting the cells against oxidative stress and recycles used vitamin E.

Biogena Ester-C® Gold: Vitamin C with 24h effect
Ester-C® Gold is a special vitamin C complex with stomach-friendly vitamin C and the vitamin C metabolite, L-threonate. L-threonate helps improve the uptake of vitamin C in the body and remains in the immune cells for a longer period. This non-acidic, stomach-friendly vitamin C complex is also recommended for sensitive individuals.

Physiological functions of the vital substance contained:

Vitamin C
• Contributes to the protection of cells from oxidative stress and contributes to the regeneration of the reduced form of vitamin E
• Supports the endogenous immune defence
• Is involved in the formation of collagen and thus supports the skin, gums, and blood vessels
• Increases iron uptake
• Helps reduce tiredness and fatigue

Vitamin C - the compound is key

When it comes to vitamin C supplementation, the exact compound used can make all the difference. Our vitamin C complex contains the patented compound Ester-C®, which is better absorbed by the body than conventional vitamin C compounds, and remains in the immune cells for longer. On top of that, we’ve added high-quality elderflower extract and quercetin as well as grape extract from controlled organic cultivation. This non-acidic premium vitamin C lasts for 24 hours and is particularly well suited for people with sensitivities.

At Biogena, “pure substance principle” means that we do not use technological additives which are used for the fully automated manufacturing of tablets, capsules and pills (e.g. anticaking or release agents and so forth) or additives that are used for optical reasons or for enhancing the taste of the products (artificial aroma, colouring agents, coatings etc.). Due to a semi-automatic manufacturing process, we can avoid these substances that often have a higher proportion in customary products than the actual active ingredients. In the case of nutritional supplements, additives have to be indicated in the list of ingredients. Here, the patient or customer can get useful information. Concerning the single ingredients, we also care for our raw materials to be free of carrier substances. In cases where this is not possible, we use natural food components such as maltodextrin, cellulose powder or calcium carbonate. The majority of our ingredients is produced exclusively for us – free of carrier substances (e.g. our enzymes our probiotics: other manufacturers often use lactose as a carrier – the product batches produced for us are explicitly without carriers).
