Essential Vitamin 2

 Today we are talking about vitamin A. Vitamin A is a fat-soluble vitamin, including A1 and A2, A1 is retinol, and vitamin A2 is 3-dehydroretinol. Vitamin A has many physiological functions such as promoting growth and reproduction, maintaining bone, epithelial tissue, vision and normal secretion of mucosal epithelium. Vitamin A and its analogs can prevent precancerous lesions. When it is lacking, it manifests as growth retardation and diminished ability to adapt to dark blindness. Vitamin A intake by the human body cannot exceed 3 mg/day for adults and 2 mg/day for children. In addition to obtaining vitamin A through food, it can also be supplemented by taking health food. Vitamin A soft capsules produced by Guangzhou Changsheng Kang Biotechnology Co., Ltd. can supplement vitamin A well.
