Product Description
- TANTAN GLUTATHIONE GOLD: This product is a supplement from Austin Pharmaceuticals. It contains Glutathione, a compound formed by the combination of three amino acids: Cystein, Glutamate, and Glycine. Glutathione plays a crucial role in the body’s oxidative reactions and is a vital antioxidant component. The body’s Glutathione content is known to decrease with age.
- Daily Recommended Dose of Vitamin C: Vitamin C is an essential nutrient for the formation and maintenance of connective tissue and protects cells from harmful oxygen, aiding immune function. The body does not produce Vitamin C, so it must be supplemented through food. Although fruits and vegetables can provide nutrients, they are insufficient to meet the body’s need for Vitamin C.
- Low Molecular Fish Collagen: Collagen is a protein that fills gaps between cells and supports cells. Collagen decreases by about 1% every year from the mid-20s and drastically decreases to half the level of the 20s by the 40s. Animal collagen has a large molecular weight and is difficult to absorb in the body, so it is necessary to consume low molecular fish collagen, which has a high absorption rate.
- 13 Types of Ingredients: TANTAN GLUTATHIONE GOLD contains 13 types of ingredients including Glutathione, Vitamin C, and Fish Collagen, making it a convenient inner beauty product that can be consumed anytime, anywhere. In addition to these ingredients, it also contains Vitamin A, Vitamin B, Vitamin E, Vitamin D, Calcium, Carrot concentrate, Blueberry concentrate, Tomato concentrate, and more.
- Reliable Manufacturer with HACCP Certification: The product is produced, manufactured, and distributed safely and hygienically in a HACCP certified manufacturing facility. HACCP (Hazard Analysis and Critical Control Point) is a food safety management certification standard. TANTAN GLUTATHIONE GOLD is recommended for those who want to consume Glutathione, want a product containing Vitamin C, and have a keen interest in vibrant faces/inner beauty.
