Dunaliella Salina Extract 2% Beta Carotene Powder
What is Dunaliella salina extract?
Dunaliella salina is a halophilic green microalga belonging to the order Volvocales in the class Chlorophyceae. It is commonly found in salt ponds. In high-salinity environments, this microalga often turns red, and its most notable feature is its exceptionally high β-carotene content, which is several times greater than that found in carrots and fruits.
Dunaliella salina β-carotene is a natural product extracted, concentrated, and refined from Dunaliella salina using modern technological methods. It is rich in natural carotenoids and contains over 70 essential minerals and trace elements beneficial to human health. A unique aspect of Dunaliella salina is that its elemental composition closely matches that of human body fluids and serum, enabling it to effectively regulate the body's mineral balance and restore equilibrium.
Moreover, Dunaliella salina β-carotene offers multiple health benefits, including antioxidant properties, radiation protection, and immune system enhancement, making it a highly valuable natural health product.
