Description

Vitamin B2, also known as riboflavin, is a member of the B-vitamin family. It is slightly soluble in water and stable when heated in neutral or acidic solutions.

As a water-soluble vitamin, it has limited solubility in water. Vitamin B2 is widely found in yeast, liver, kidneys, eggs, milk, soybeans, and other foods.

Advantages:

Eye Protection

A deficiency in vitamin B2 may lead to discomfort such as blepharitis and corneal damage. Supplementation under medical guidance can effectively prevent blepharitis, promote corneal recovery, relieve visual fatigue, nourish the retina, and protect eye health.

Prevention of Iron-Deficiency Anemia

Vitamin B2 significantly enhances the body’s absorption of iron. Therefore, appropriate supplementation can effectively prevent iron-deficiency anemia and maintain overall health.

Protection of Skin and Mucous Membranes

Inadequate intake of vitamin B2 often causes skin problems such as stomatitis, cheilitis, and seborrheic dermatitis. Vitamin B2 promotes cell regeneration, enhances metabolism, improves protein utilization efficiency, ensures the normal function of hair follicles and sebaceous glands, and maintains the integrity of skin and mucous membranes.
