Marine Collagen Peptides

Hydrolyzed Collagen (Type I & III)

胶原蛋白肽

Pinyin: Jiāo Yuán Dàn Bái Tài

🌿

Plant Family

Protein supplement (not a plant)

Part Used

Hydrolyzed protein peptides

Origin

Fish skin/scales (marine), bovine hide, chicken sternum

Safety Level

Safe

Overview

Collagen is the most abundant protein in the human body, forming the structure of skin, bones, tendons, ligaments, and cartilage. Collagen peptides are small fragments of collagen protein (usually 2-5 kDa) that are highly bioavailable. Marine collagen (from fish) is particularly popular for skin health because it is rich in Type I collagen and has small peptide size for better absorption.

Active Constituents

The key compounds responsible for this herb's therapeutic effects:

Type I collagen (skin, bones, tendons) - marine is mostly Type IType II collagen (cartilage)Type III collagen (skin, muscles, blood vessels)Amino acids: glycine, proline, hydroxyproline, hydroxylysineGlycine - primary amino acid in collagen (~33%)Low molecular weight peptides (2-5 kDa for better absorption)Note: Peptides are 2-20 amino acids long; proteins are 50+

Usage & Dosage

How to Use

Used as powder, capsules, tablets, liquid shots, and added to many beauty products. Collagen powder is the most popular form - it mixes easily with water, coffee, smoothies, or food. Best taken on an empty stomach or before meals for maximum absorption.

Suggested Dosage

2.5-10g daily for skin health. 10-15g daily for joint and bone health. Powder is most cost-effective. Take daily for at least 4-8 weeks to see results. Best taken on empty stomach or with vitamin C for enhanced collagen synthesis.

Quality & Storage

Harvest Season

Produced year-round from byproducts of fishing and meat processing industries (sustainable use of skins, bones, and scales that would otherwise be discarded).

Quality Indicators

Marine collagen from wild-caught fish is preferred. Look for hydrolyzed collagen peptides with molecular weight <5kDa. Type I & III for skin, Type II for joints. Should mix easily without clumping. Third-party testing for heavy metals is important (especially for marine sources).

Storage

Store powder in cool, dry place. Shelf life: 2-3 years. Once opened, use within 6 months for best freshness. Keep container tightly closed to prevent moisture absorption.

Safety Information

Contraindications

Generally very safe for most peopleFish/shellfish allergy (if marine collagen)Pregnancy and breastfeeding: generally recognized as safe but limited dataChildren: not well studiedThose with kidney disease (high protein intake - consult doctor)Vegans: marine/bovine/chicken collagen is not vegan - use plant-based alternatives

Possible Side Effects

  • Very safe and well-tolerated by most people
  • Mild digestive upset (bloating, feeling of fullness) - rare
  • Bad taste in mouth (some brands)
  • Allergic reaction (if allergic to source - fish, etc.)
  • Calcium content in some bone broths (consider if on low-calcium diet)
  • Very rare: headaches

Drug Interactions

  • Very few known drug interactions
  • Antibiotics (separate doses - protein may bind)
  • Blood thinners (very mild effect - not a major concern)
  • Generally very low interaction risk

Pearl Powder

Margarita (Pteria / Pinctada species)

Pearl powder is made from ground freshwater or saltwater pearls. It has been used for thousands of years in both Chinese and Ayurvedic medicine as a beauty tonic and calming agent. In ancient China, it was used by empresses and noblewomen for beautiful, luminous skin. Modern science has confirmed many of its skin benefits.

Royal Jelly

Apis mellifera (honeybee secretion)

Royal jelly is a creamy, yellowish-white substance secreted by the hypopharyngeal and mandibular glands of young worker bees. It is fed exclusively to the queen bee throughout her life, which is why she grows much larger and lives 40-50 times longer than worker bees. Royal jelly has been used in both traditional and modern medicine for its rejuvenating and health-promoting properties.

Pearl Powder

Margarita (Pteria / Pinctada species)

Pearl powder has been used for thousands of years in traditional Chinese medicine and Ayurveda as a beauty and longevity tonic. It was prized by empresses and royal women for its skin-enhancing effects. Pearl is composed mainly of calcium carbonate along with trace minerals, amino acids, and conchiolin protein. When finely ground, it can be used both internally and topically.

Vitamin C (Ascorbic Acid)

Vitamin C (Ascorbic Acid / L-ascorbic acid)

Vitamin C is an essential water-soluble vitamin and powerful antioxidant that the human body cannot produce on its own (unlike most animals). It is vital for collagen synthesis, immune function, antioxidant defense, and numerous other bodily processes. Vitamin C is also one of the most well-known beauty nutrients for its role in collagen production and skin brightening. While scurvy (severe vitamin C deficiency) is rare today, many people do not get optimal amounts.
