Peptide Knowledge

Peptides can generally be divided into two major categories: animal-derived peptides and plant-derived peptides. Most products on the market that claim to contain “small-molecule peptides” are actually plant-derived peptides (plants do not contain collagen). These peptides have a single-chain, planar structure (such as soy isoflavones or genistein). Because their structural form and amino acid composition […]

Peptide-based cosmetics are skincare products that use nano-sized peptides as their key active ingredients. Their greatest advantage is that when the molecular weight is below 1,500 Daltons, the peptides can be directly absorbed through the skin. Read More: Fishelton Skincare products

Collagen with a purity below 90% is used in food products. Collagen with a purity between 90% and 95% is used as a cosmetic ingredient. Collagen with a purity above 95% (with the remaining content mostly being moisture and sterile-treated) can be used for medical-grade applications.

The raw material is sourced from fish scales, which eliminates concerns about zoonotic viruses. According to testing reports from National Pingtung University of Science and Technology, the product’s purity ranges from 96.62% to 98%, outperforming two well-known Japanese brands (90–91%) and even surpassing the 95% purity developed by Taiwan’s Fisheries Research Institute.

It can enhance immune function Inhibit cancer cell growth Activate cellular functions Promote blood clotting Relieve joint pain and arthritis Prevent skin aging Reduce wrinkles, among other functional benefits.

Collagen, commonly known as a connective protein, has a large molecular structure. After ingestion, it remains in the stomach, where gastric acid (dilute hydrochloric acid) breaks it down into amino acids. These amino acids are then absorbed through the duodenum and transported to the liver, where they are first synthesized into peptides. Depending on the

According to research, after the age of 25, the collagen in human tissues decreases by about 1.5% each year — meaning that every decade, approximately 15% of collagen is lost. As a result, connective tissues rich in collagen, such as skin, bones, cartilage, and muscles, begin to show visible signs of aging and deterioration.

Japan is the most advanced country in applying peptides—derived from collagen hydrolysis—to food. Initially, they were developed as space food for astronauts and nutritional supplements for Olympic athletes. Later, peptides were incorporated into school lunch programs and provided free of charge to kindergarten, elementary, and middle school students. This initiative led to a rapid increase

Peptides are called “peptides” in English and referred to as “核酸” (nucleic acids) in Japanese. Currently, in Western countries, they are used as dietary supplements to support the treatment of cardiovascular diseases and cancer. In Japan, peptides are regarded as a “secret weapon” and are planned to be launched in about two years as a
