Beta-Carotene

Other applications

Please note:

Any dietary or drug treatment with high doses of micronutrients may override the body's own control mechanisms; therefore, micronutrient therapies may be associated with potential side effects and toxicities. High-dosed micronutrients should not be used without medical supervision.

Sun sensitivity

Studies suggest that high doses of beta-carotene may decrease sensitivity to the sun: in people with ‘erythropoietic protoporphyria’, a rare genetic photosensitivity disorder leading to abnormal skin reactions to sunlight, beta-carotene in doses of up to 180 mg has been shown to reduce sun sensitivity (38).

Sun protection:

Much lower doses of 10-20mg beta-carotene may protect from UV-induced erythema (sunburn) and protect from the skin from photoaging (72, 73).

Immune system

Several reports suggested that supplementation with beta-carotene influences and strengthens our immune system, i.e. the number of common colds are reduced in smokers. Other reports points to a reduction of the inflammatory burden, such as in diabetic patients (37) or in patients with cystic fibrosis.
