Health claims

Vitamin A contributes to the maintenance of normal skin.

Vitamin A contributes to the maintenance of normal vision.

Vitamin A contributes to the normal function of the immune system.

Vitamin A is a fat-soluble vitamin and antioxidant that helps the formation and maintenance of bone and soft tissues, teeth, mucous membranes and skin.

Vitamin A helps in maintaining healthy skin and lessens the effects of photoaging. Their consumption stimulates the production of melanin (pigment responsible for the coloration of the skin) and improves the hydration of the skin. In addition, it also promotes healthy hair by contributing to capillary regeneration.

This vitamin is obtained from foods of animal (preformed vitamin A) and plant origin (carotenoids). β-Carotene is a provitamin A carotenoid: it is converted to retinal in the liver and, unlike vitamin A of animal origin, is not accumulated and only transformed into vitamin A when the body needs it.

Our provitamin A is 100% natural and is suitable for vegans, since it comes from Dunaliella salina, an algae that can accumulate up to 40% of its dry weight in β-carotene. One dose of our product provides 100% NRVs* of vitamin A.

Detailed information

Carotenoids and vitamin A

Vitamin A is an fat-soluble antioxidant vitamin that accumulates in the liver. This vitamin is essential for growth and development, helps to maintain good vision, protects the body against infection and improves skin health1, 2. It also plays a key role in the reproductive system, cell functions and immune system2.

We can obtain two types of vitamin A from food: preformed vitamin A (retinol, retinyl ester, retinal, 3-dehydroretinol and retinoic acid) of animal origin, or provitamin A carotenoids, which are found in fruit and vegetables3.

Carotenoids are pigments synthesised by algae, plants and photosynthetic bacteria. There are more than 600 types, and human beings acquire them through diet. Carotenoids include those known as provitamin A carotenoids (α-carotene, β-carotene and β-cryptoxanthin), which are converted to retinol in the liver4. Provitamin A also has the advantage of converting to vitamin A only when the body needs it, avoiding any toxicity from consuming too much vitamin A.

Vitamin A is necessary for the development and maintenance of several tissues, including the skin and hair. Vitamin A has been found to induce the anagen, or hair growth, phase5. Vitamin A also helps to maintain healthy looking skin: retinol applied topically helps to decrease the effects of photoaging6, and one study has demonstrated the efficacy of administering vitamin A orally to treat sun-damaged skin7.

What is dunaliella?

Dunaliella (Dunaliella salina (Dunal) Teodoresco) is a green algae that tolerates high concentrations of salt. This algae contains carotenoids, primarily β-carotene (90% of the total carotenes) and also lutein (5%). When subjected to stress conditions, it can also hold large amounts of β-carotene in its chloroplasts (up to 40% of its dry weight)8.

Our product: Dry extract of dunaliella algae standardised to contain 30% β-carotenes.

Scientific name: Dunaliella salina (Dunal) Teodoresco
