Botanical Cube Inc. is one of the most professional manufacturers and suppliers of fish collagen peptides in China, featured by quality products and good price. Please rest assured to wholesale bulk discount fish collagen peptides from our factory.
Fish collagen peptides are a highly bioavailable source of marine collagen, extracted primarily from fish skin or scales by enzymatic hydrolysis. Rich in low molecular weight type I collagen peptides, they are well absorbed and play a key role in maintaining skin elasticity, moisturizing, and regenerating connective tissue.Consumers are increasingly choosing fish collagen for beauty and joint health formulations because it has a better absorption rate than bovine collagen and is compatible with pescatarian and halal/kosher diets.
Our factory specializes in producing high-purity fish collagen peptides using food-grade, traceable fish sources. Our production focuses on ultra-low molecular weight peptides (<1000 Da) to ensure rapid bioavailability and neutral taste, whether you are producing beauty powders, capsules or functional beverages, our product can combine the best performance and purity.
Why choose our fish collagen peptides?
1. Ultra-low molecular weight – <500 Daltons
Our peptides are always hydrolyzed to <500 Daltons. This significantly increases the rate of absorption and bioavailability.
2. Deodorization and decolorization filtration
We use a multi-stage deodorization system that removes more than 92% of fishy compounds and a food-grade activated carbon process to eliminate discoloration without affecting the integrity of the peptides. The end result: a neutral-tasting, clear-colored powder - perfect for beauty drinks and sensitive formulations.
3. Stable protein content – ≥94%
Our protein concentration remains stable thanks to precise enzyme control and advanced membrane concentration technology.
4. High solution clarity
Our powder has a transmittance of up to 96% (1% solution) at a wavelength of 620 nm, making it ideal for high-end beverages and transparent supplements.
5. Customized peptide analysis services are available
We provide customized molecular weight distribution and amino acid fingerprint reports, so you can tailor your formulation to your specific needs such as skin regeneration, joint health or sports recovery.

FAQs of fish collagen peptides
1. Is fish collagen better than bovine collagen?
Fish collagen has a smaller molecular weight (typically less than 500 Da) and is more bioavailable. It absorbs faster and is especially beneficial for skin hydration and elasticity.
2. Can it be used in hot beverages such as coffee or tea?
Yes. Fish collagen peptides are heat resistant up to 120°C and dissolve quickly in both hot and cold liquids.
3. Will it affect the taste of food or beverages?
Our ultra-refined collagen is virtually odorless and colorless in solution, and has a light transmittance of >96% in water, making it ideal for clear or light-flavored products.
