Objective: The purpose of this experimental study was to investigate the role of vitamin supplements (Ocuvite, Vitalux Omega, and Nutrof Total) as possible inhibitors of the onset of age-related macular degeneration (AMD).
Materials And Methods: The anti-aggregating effect of each vitamin was determined against four accumulative factors namely, platelet activating factor (PAF), adenosine diphosphate (ADP), thrombin receptor-activating peptide (TRAP), and arachidonic acid (AA) in the platelet rich plasma (PRP) of healthy volunteers.
Results: Ocuvite, Vitalux Omega, and Nutrof Total were more potent inhibitors against PAF and ADP compared to TRAP and AA. Among the three vitamins, Nutrof Total displayed more potent inhibitions against TRAP and AA, while against PAF and ADP all the three vitamins revealed similar IC values.
Conclusions: The vitamins Ocuvite, Vitalux Omega, and Nutrof Total have anti-aggregating effects and therefore can be used against AMD in healthy volunteers.

Age-related macular degeneration (AMD) and diabetic retinopathy (DR) are common retinal diseases responsible for most blindness in working-age and elderly populations. Oxidative stress and mitochondrial dysfunction play roles in these pathogenesis, and new therapies counteracting these contributors could be of great interest. Some molecules, like coenzyme Q (CoQ), are considered beneficial to maintain mitochondrial homeostasis and contribute to the prevention of cellular apoptosis.

To prevent ocular pathologies, new generation of dietary supplements have been commercially available. They consist of nutritional supplement mixing components known to provide antioxidative properties, such as unsaturated fatty acid, resveratrol or flavonoids. However, to date, few data evaluating the impact of a mixture mainly composed of those components (Nutrof Total®) on the retina are available.

To prevent ocular pathologies, new generation of dietary supplements have been commercially available. They consist of nutritional supplement mixing components known to provide antioxidative properties, such as unsaturated fatty acid, resveratrol or flavonoids. However, to date, only one preclinical study has evaluated the impact of a mixture mainly composed of those components (Nutrof Total) on the retina and demonstrated that in vivo supplementation prevents the retina from structural and functional injuries induced by light.

Age-related macular degeneration (AMD) is a multifactorial disease of the retina featured by dysfunction of retinal pigmented epithelial (RPE) and loss of photoreceptor cells under oxidative stress and inflammatory conditions. Vitamin D and antioxidants have beneficial effects against retinal degenerative diseases, such as AMD. We investigated the impact of associating vitamin D (ND) with a nutritional antioxidant complex (Nutrof Total; N) on oxidative stress and inflammation-like induced conditions by HO and LPS, respectively, in human retinal epithelial (ARPE-19) and human retinal endothelial (HREC) cells.

Objective: To analyse the morphometric characteristics and the concentration of (docosahexaenoic acid) DHA and eicosapentaenoic acid (EPA) of the different nutritional supplements with omega 3 available on the market for retinal disease.
Material And Methods: A double-blind study was conducted with a single observer, of the different omega 3 supplementation tablets sample marketed in Spain. The length of the tablet, the concentration of omega 3 in total, as well as DHA and EPA were studied separately using the amount provided by the manufacturer and the volume of the capsule calculated from the development of a specific formula for it.
