Black rice and Opuntia ficus-indica flower extract formula standardised to provide anthocyanins – the combination of black rice and Opuntia ficus-indica flower extract is the subject of a patent1. Black rice is a type of rice commonly grown and consumed for a long time in Southeast Asian countries. It is rich in nutrients and bioactive compounds, such as anthocyanins, which are responsible for its dark colour. Opuntia ficus-indica flowers, not only contain vitamins (A, C, E, B group), but are also a source of calcium, magnesium and fibre. In addition, the flowers also contain valuable alkaloids and flavonoids.

Solubilised keratin – keratins are a group of fibrillary, water-insoluble proteins produced by keratinocytes in the epidermis. They are the main structural component of hair and nails. Keratin contains a large share of sulphur-containing amino acids (cysteine and cystine), forming so-called disulphide bridges, so it is resistant to mechanical and chemical agents. Keratin is an inedible protein, it is not absorbed from the gastrointestinal tract, therefore, in an oral form, products of its degradation, containing valuable amino acids (solubilised or hydrolysed keratin, contrary to keratin it is soluble in water). The solubilised keratin used in DUOLIFE Kertain Hair Complex was obtained in a patented process of controlled hydrolysis of sheep wool, maintaining its original amino acid profile. Amino acids found in the product are absorbed after oral administration and represent a building component used by the human body to create natural keratin.

Moreover, nettle leaves include such substances as: chlorophyll, xantophyll, carotene, tannins, vitamins (C, K and B2, pantothenic acid), as well as flavonoids (kaempferol, quercetin, rutin, isorhamnetin).
