Why did Colway offer consumers its own vitamin C, when close to 8,000 different products with this same name have been launched into markets in Europe alone?

In present times can one develop a unique product in such a tightly saturated niche market?

It turned out to be possible.

Close to 96% of the items purchased by consumers around the world, is usually synthesised in Chinese factories with American right-handed dextrose, crystalline ascorbic acid. A form, which for a million years was unknown to our bodies, and therefore, it poorly absorbs it. The further 3% is a mixture of the former with vitamin C extracted from biomass. Only a faint percentage constitute pure plant preparations. And then, however, the bioavailability of vitamin C in these products varies considerably.

The best form of vitamin C, which contain plant growth stems, are very rare on the market, as it is not a profitable business.

Vitamin C supplementation C-olway is obtained from fruit, skin, albino and young leaves of bitter orange and buckwheat sprouts.

It does not contain fillers and additives of ascorbic acid or its derivatives. It is bio-organic, levorotatory and avant-garde. Supplements based on these herbal ingredients are only just gaining demand from consumers.

Vitamin C is the most important vitamin for the functioning of our body. Colway is a publisher of the broadest literature so far describing it in popular scientific publications. Foremost among hundreds of its biological functions seems to be conditioning of collagen biosynthesis – the process by which our connective tissue is formed.

Vitamin C-olway stormed into a group of products recognized as the best in this group of supplements in Europe. It has become one of our best sellers.
