The dietary supplement based on pharmacologically normalized Dunaliella salina algae dry extract, Lutein, Zeaxanthin, Zinc, Copper and Selenium that helps to hinder the degradation of retinal cells typical of Retinitis Pigmentosa. With 6 components : - Dunaliella salina . Dunaliella salina algae dry extract pharmacologically standardized whose main component is β-carotene. Supplementation with the 9-cis β-carotene isomer has been shown through clinical trials to significantly increase the functionality of the retina in RP patients (1). Benavist-containing standardized Dunaliella salina algae dry extract has a concentration of up to 90% β-carotene, of which 37% is 9-cis β-carotene and the remainder are all-trans β-carotene isomers. All-trans β-carotene are metabolized and transformed in the body into the active 9-cis β-carotene isomer, which is responsible for increasing ocular functionality and slowing down the progression of RP (2), (3 ). - Lutein . Supplementation with this carotenoid improves agility and visual field in RP patients (4). Lutein supplementation slows the loss of the median peripheral visual field in RP patients. In this way, taking Lutein perfectly complements supplementation with β-carotene (5). - Zeaxanthin . It is a carotenoid that acts as an antioxidant along with Lutein, protecting the eye photoreceptors, reducing their degeneration and preventing possible loss of vision (6). - Zinc, Copper and Selenium . Zinc is vital for eye health, it is necessary to supplement with copper when we supplement with Zinc since they compete in its absorption. Selenium is a powerful antioxidant. Retinitis Pigmentosa (RP). Taking Benavist provides the necessary carotenoids from the extract of Dunaliella salina, Lutein and Zeaxanthin, which protect the eye photoreceptors and help slow down progression and improve visual function in RP patients. Take 2 capsules a day (1-0-1). One capsule during or after breakfast and another during or after dinner with a glass of water except for another medical prescription. No contraindications or negative side effects have been described with the recommended dosage. There are some people who do not metabolize β-carotene well and this manifests itself in a yellow discoloration on the palms of the hands and feet that appears after taking it for several days. In the event that this occurs, treatment can be discontinued, not because it is harmful, but because it is useless. Its use in pregnancy and lactation is not recommended due to not having carried out evidentiary tests. Its use is not recommended in non-adults for not having carried out evidence tests
