Zeaxanthin dosage is inadequate for AMD prevention
Zeaxanthin dosage is not enough for eye health. It is true that zeaxanthin and lutein are mainly concentrated in the macula. And age-related macular degeneration (AMD) is mainly caused by a deficiency of these nutrients circulating in the bloodstream. Yet another risk factor for AMD is high cholesterol. But the current situation is that many doctors and supplement manufacturers only advocate lutein and zeaxanthin for AMD prevention.
Nutrients manufacturers always play tricks
Prohibited from making misleading statements, nutrients manufacturers instead post videos from TV news stories or talk shows at their websites. But these media reports can also be misleading. Just like the advertising of lutein and zeaxanthin, resveratrol is another commonly promoted ingredient. Supplements containing resveratrol are often touted as anti-aging formulas.
Resveratrol is not the only beneficial ingredient contained by red wine
However, there is no evidence showing that resveratrol is the only compound responsible for the health benefits from red wine, even though it is a potent antioxidant. Researchers opt to consider that all different antioxidants found in red grape skins contribute to the red wine’s health benefits. Other antioxidants include proanthocyanidins and anthocyanins.
A comprehensive formula is recommended
Healthy vision depends on various factors. When it comes to nutrients, a lutein and zeaxanthin dosage is not adequate. Other nutrients also play a role in preventing poor vision. Regular substances include anthocyanins, beta-carotene, glucosamine, n-acetyl cysteine, B12, B2 and so forth. A well designed supplement formula should contain most of these nutrients, rather than only lutein and zeaxanthin. In addition, good supplements should also be capable of lowering cholesterol levels.
Ineffective supplements advertised on TV
Customers may be disappointed by some supplements advertised on TV news stories or talk shows. Single-nutrient supplements are not miracle pills. They are not enough to reduce the risk of macular degeneration. What’s more serious, some supplement manufacturers use synthetic nutrients in their products. Made of petroleum, these synthetic ingredients are usually called plastic vitamins. Vitamins and some acids are widely believed to be effective in preventing macular degeneration. At least, a good supplement formula should include these nutrients. By including only a single zeaxanthin in their products and claiming unusually cheap prices, some manufacturers only aim to gain profit. Those supplements are just ineffective and a waste of money.
In a word, fighting against age-related macular degeneration requires the combined efforts from various antioxidants as well as other necessary nutrients. Single zeaxanthin dosage is inadequate. A simple tip for supplement selection is to choose a prestigious brand or manufacture.
