Product Overview
Sea buckthorn (Hippophae rhamnoides), known in some regions as the "holy fruit of the Himalayas," has been a cornerstone of traditional wellness systems across Central Asia, Tibet, and Northern Europe for centuries. Its bright orange berries are renowned for an extraordinary concentration of bioactive nutrients — including vitamins, flavonoids, carotenoids, and essential fatty acids.
Through advanced enzymatic hydrolysis, we have isolated the protein fraction of sea buckthorn fruit into ultra-low-molecular-weight active peptides (<500 Da). At this molecular scale, these peptides represent the cutting edge of plant-based bioactive ingredients: smaller than most conventional oligopeptides, they offer near-instantaneous absorption and exceptional bioavailability, bypassing digestive breakdown to deliver functional amino acid sequences directly to target tissues.
Our Sea Buckthorn Peptides are manufactured to ≥98% purity under strict food-grade conditions. The product dissolves readily in water to yield a clear, transparent solution (pH 5.5–6.5), making it exceptionally well-suited for clear beverages, wellness shots, and liquid nutraceuticals — applications where many other plant peptides fall short due to turbidity or sedimentation. With its ultra-low molecular weight, high purity, and superior solubility, this ingredient offers formulators an unmatched combination of efficacy and processability.

Mechanisms of Action & Key Bioactivities
Sea buckthorn peptides exert their health benefits through multiple distinct pathways, many of which are enhanced by the ultra-low molecular weight (<500 Da) enabling rapid systemic delivery:
1. Cardiovascular System Support
Peptide sequences with ACE-inhibitory activity help maintain healthy blood pressure levels
Support healthy serum lipid profiles by modulating cholesterol and triglyceride metabolism
Bioactive peptides interact with vascular endothelial cells to promote healthy circulation
The natural flavonoid and peptide synergy provides comprehensive cardiovascular protection
2. Gastrointestinal Mucosal Protection
Bioactive peptides help maintain the integrity of the gastric mucosal barrier
Support the natural repair mechanisms of the digestive epithelium
May help soothe and protect the gastrointestinal tract from environmental stressors
Traditional use of sea buckthorn oil for digestive health is now complemented by the peptide fraction
3. Potent Antioxidant & Free-Radical Defense
Ultra-low molecular weight enables direct intracellular antioxidant activity
Scavenge reactive oxygen species and reduce oxidative stress markers
Protect cellular membranes and DNA from oxidative damage
Support the body's natural antioxidant enzyme systems
4. Immune Function Enhancement
Stimulate immune cell activity and enhance natural defense mechanisms
Support the production and function of immunoglobulins
Help maintain the body's resistance to environmental challenges
5. Anti-Fatigue & Physical Recovery
Facilitate the removal of metabolic waste products (lactic acid, urea nitrogen)
Provide readily utilizable nitrogen for muscle repair and energy regeneration
Support endurance and reduce perceived exertion during physical activity
Accelerate post-exercise recovery when incorporated into sports nutrition
6. Nutritional Synergy
The peptide fraction works synergistically with sea buckthorn's naturally occurring vitamins, flavonoids, and carotenoids
Low molecular weight ensures that both peptide and non-peptide nutrients benefit from enhanced absorption

Processing Highlight: The product's ability to form a clear and transparent aqueous solution (pH 5.5–6.5) is a key differentiator for manufacturers of liquid products, where clarity is often a critical quality parameter. No additional clarification or filtration steps are typically required.
Note: Recommended dosages are for reference only; final use levels should be determined based on target health claims and regulatory compliance.
