Life Extension® introduces the world’s first oral supplement to help protect against harmful solar radiation. For the first time you can achieve essential protection from dangerous sun exposure in a pill.

During a decade of clinical trials, FernBlock® has shown remarkable effectiveness in shielding skin against dangerous ultraviolet exposure.33-38 Studies have shown that this fern extract has a high affinity for skin tissue and helps protect against ultraviolet damage shown to cause premature skin aging and wrinkling.39,40

FernBlock® is a natural extract derived from the fern plant Polypodium leucotomos. Used as a sunburn remedy by native Indians for centuries, this natural fern extract has been formulated by international scientists affiliated with leading institutions. For the first time, researchers have created a unique oral formulation of sun-protective compounds from this natural extract.

The highly targeted action of FernBlock® safely inhibits the absorption of harmful ultraviolet rays and quenches dangerous free radicals.33,35 FernBlock® also helps mitigate the consequences of excessive ultraviolet radiation by reducing the number of skin cells that indicate sun-induced injury.35,36 Additionally, it helps inhibit pro-inflammatory cells that cause redness and itching,35 blocks protein-destroying skin enzymes that decrease skin elasticity,41 and preserves the skin’s antioxidant status.42

This product has been upgraded to contain SendaraTM, a patented blend of the herbs ashwaganda and Indian gooseberry. Ashwaganda has been used by Ayurvedic practitioners in its native India for thousands of years. It is rich in flavonoids and steroidal lactones called withanolides, which are thought to have a number of beneficial properties. Ashwaganda works as an adaptogen to enhance the bodyís ability to respond to stress, which is thought to be a major contributor to physical signs of aging and that can exacerbate or trigger certain skin conditions. This adaptogen specifically targets excess cortisol release triggered by stress. Indian gooseberry is an antioxidant that helps prevent oxidative stress and degradation of skin proteins and may enhance the firmness of skin.43,44

Sendara combines these two ingredients into one anti-aging cosmeceutical. In addition to providing stress relief for the skin, Sendara also offers skin benefits, in terms of skin appearance, by inhibiting the enzyme that cleaves and damages collagen, a primary structural protein of the skin. Sendara also helps in retaining skin moisture by inhibiting the enzyme hyaluronidase.43,44

FernBlock® is designed to complement topical sunscreens for intense sun exposure. Topical sunscreens are effective if properly and regularly applied, especially for long periods of sun exposure. FernBlock® supplements the effects of sunscreens by protecting the entire skin surface and has an obvious advantage since it cannot be removed by perspiring or bathing.

For intense sun exposure, two to three capsules of FernBlock® and an effective sunscreen provide convenient and complete day-long protection. For short periods of sun exposure (such as walking to the car) that can add to cumulative ultraviolet damage, just one FernBlock® capsule should provide adequate protection.

Remember, for long periods of sun exposure, you should defend your skin against premature photoaging with FernBlock® and a topical sunscreen to ensure complete sun protection.
