Discover the ingredients of DUOLIFE Liquid Dietary Supplement with Keratin

Guava fruit puree guava fruit is a source of numerous antioxidants such as vitamin C, carotenoids (beta-carotene and lycopene) and polyphenols (ellagic acid, quercetin and anthocyanins), and also contains a significant amount of fiber, tannins, essential oil, vitamins and minerals.

Raspberry fruit juice - raspberries are a source of polyphenolic compounds (flavonoids, anthocyanins, phenolic acids), vitamins (A, C, E, group B), minerals, organic acids, sugars, fiber and others.

Amla fruit extract - amla (Indian gooseberry) is a valuable source of vitamin C. In the DUOLIFE Liquid Dietary Supplement with Keratin product, this extract is standardized to 70% vitamin C content.

Organic pea shoot extract - pea shoots are rich in nutrients. They contain, among others, protein, carbohydrates, vitamins (C, A, E, group B), minerals (potassium, phosphorus, calcium, magnesium, copper, zinc) and fiber.

Solubilized keratin - keratins are a group of water-insoluble fibrillar proteins produced by epidermal keratinocytes. They are the main building block of hair and nails. Keratin contains a large amount of sulfur amino acids (cysteine and cystine) that form so-called disulfide bridges, which make it resistant to mechanical and chemical factors. Keratin is an inedible protein, it is not absorbed from the gastrointestinal tract, therefore its degradation products containing valuable amino acids are used in oral form (solubilized keratin, also known as hydrolyzed keratin; unlike keratin, it is soluble in water). The solubilized keratin used in DUOLIFE Liquid Dietary Supplement with Keratin was obtained in a patented process of controlled hydrolysis of sheep wool, maintaining its original amino acid profile. The amino acids contained in the product are absorbed after oral administration and constitute a building block used by the body to create natural keratin.

Nettle leaf extract - nettle is a valuable source of silica (silicon), but also many other minerals (magnesium, calcium, iron, potassium). Additionally, nettle leaves contain substances such as: chlorophyll, xanthophyll, carotene, tannins, vitamins (C, K and B2, pantothenic acid) as well as tannins and flavonoids (kaempferol, quercetin, rutin, isorhamnetin).

Horsetail extract horsetail herb contains many valuable active substances, including: flavonoids (including derivatives of luteolin, apigenin, quercetin and kaempferol), phenolic acids, minerals, including silicic acid (about 66%), soluble silicon compounds, potassium, magnesium and aluminum salts.
