Macuguard® Ingredients*
We only evaluate bioactive ingredients—the ones that truly contribute to a product's performance. Below is a list of bioactive ingredients found in this product.
For each ingredient, the quantity in parentheses indicates the amount per serving.
MacuGuard® proprietary blend contains Marigold extract, phospholipids, mixed carotenoids.
Marigold extract, commonly derived from the Tagetes erecta flower, is rich in lutein and zeaxanthin, which are antioxidants known to support eye function. It is often included in dietary supplements formulated for eye health.
Phospholipids are included in some dietary supplements, often as a component of ingredients like krill oil or soy lecithin. Their presence can influence how other nutrients, such as omega-3 fatty acids, are packaged and assimilated by the body.
Mixed carotenoids are a blend of plant pigments that act as antioxidants, supporting eye health, skin protection, and immune function.
Saffron extract, derived from the dried stigmas of the Crocus sativus flower, contains active compounds like crocin and safranal that have antioxidant properties. It is often used in dietary supplements to support mood balance and eye health.
Natural Astaxanthin is a powerful antioxidant derived from microalgae, known for supporting skin health, eye function, and cellular protection against oxidative stress. Its unique molecular structure makes it significantly more potent than other antioxidants like vitamin C and beta-carotene.
