SUPPORTS HEALTHY SKIN - One of the most significant benefits of beta-carotene is skin health support. Beta carotene delivers an impressive amount of antioxidant support, which helps your skin defend itself from environmental hazard and free radical damage that could accelerate the effects of aging on the skin.

GREAT FOR EYE HEALTH - If you're looking to boost vision support, beta-carotene is an excellent choice. That's because it not only supports the eye's ability to protect itself (especially the cornea), but it also promotes eye lubrication. Vitamin a deficiency, on the other hand, comes with a host of vision and retinal health concerns. Beta-carotene supplements can help cover vitamin A gaps in your diet as your body readily converts beta carotene into vitamin A.

BETA CAROTENE VS. OTHER FORMS OF VITAMIN A - Beta-carotene is slightly different from most types of vitamin a because it's considered a pro-vitamin A carotenoid. Pro-carotenoids need to be broken down and converted into vitamin A after ingestion. Each Swanson Beta-Carotene Sgel delivers 7,500 mcg and 833% daily value of vitamin A as beta-carotene to support immune system, vision, skin and hair health every day.

Features

SUPPORTS VISION HEALTH - Zeaxanthin is a macular carotenoid found in vegetables, plants and fruits. In the body, zeaxanthin is found in the eye in the yellow spot of the retina, which protects the macula from damage from high-energy blue light and oxidative stress due to free radicals. Since the body does not produce macular carotenoids, diet and supplements are two ways to increase zeaxanthin and astaxanthin intake to help promote healthy eyes and vision, especially as we age.

PROTECTS AGAINST BLUE LIGHT - In today's modern digital environment, your eyes are bombarded almost constantly with potentially harmful high-energy blue light waves emitted from your smartphone, tablet, laptop, TV and other digital screens or electronic devices. Swanson Astaxanthin & Zeaxanthin provides targeted antioxidants to nourish your eyes, helping them fight back against this overexposure of artificial digital light, plus environmental and age-related vision health concerns.

PROMOTES HEALTHY SKIN & RETINAS - With 4 mg of astaxanthin and 4 mg of OmniXan zeaxanthin per 1 softgel serving, Swanson Astaxanthin & Zeaxanthin delivers vital nutrition to help protect the health and function of the retina, the layer of nerve cells lining the back wall of your eyes, plus promote antioxidant activity in the body. These antioxidants team up to protect body and mind against oxidative stress, providing valuable free radical protection for skin, vital organs, tissues and more.
