Macular pigment density: vital for healthy vision

Maintaining healthy levels of carotenoids, like lutein and zeaxanthin that make up the macular pigment in your retina is essential for maintaining eye health.⁴ Macular pigment density is also essential to healthy vision.^5,6 But levels of macular pigment gradually decline over time.⁷ That's why MacuGuard® contains lutein as well as trans-zeaxanthin and meso-zeaxanthin, powerful carotenoids that are difficult to get from diet alone.

Lutein and zeaxanthin support underlying photoreceptor cells against oxidative stress, inhibit the effects of excess light and promote a healthy inflammatory response to support eye health. ^8-11 We’ve also added Alpha-carotene which your body needs to make vitamin A. Vitamin A is essential to maintain a healthy eye structure and function.¹²

Phospholipids for lutein absorption

Phospholipids help support phytonutrients like lutein reach the bloodstream. They also help protect active compounds from degradation.¹³ Pre-clinical evidence indicates that phospholipids can promote lutein absorption, encouraging the circulation and accumulation of lutein within the retina.^14-16

Nutrition for night vision: C3G berry flavonoids

MacuGuard® also contains cyanidin-3-glucoside, a flavonoid derived from European black currant berry extract.  Pre-clinical evidence suggests that this potent antioxidant encourages the regeneration of rhodopsin, a light-sensitive retinal pigment which promotes visual acuity in low-light conditions.^17-19

Age-related decline of rhodopsin plays a role in the loss of night vision, so this nutrient may support healthy night vision in older eyes.²⁰ C3G can also help inhibit inflammation to support eye health.²¹

Vision-enhancing benefits of saffron

This formula also includes saffron to support healthy vision.^22-24 People supplementing with saffron showed seeing an average of two additional lines on the Snellen eye chart commonly used by doctors to test vision.²³
