Usage & Dosage
How to Use
Used both internally (powder, capsules, dissolved in water) and topically (face masks, creams, serums). For best absorption, pearl powder should be extremely fine (micronized or "ultra-fine"). Traditional preparation involves boiling the powder 9 times.
Suggested Dosage
Internal: 300-500mg daily (fine powder, mixed with water, milk, or juice). Topical: 1-5% in creams, masks, or serums. Face mask: mix with water, honey, or yogurt, apply 10-15 min.
Quality & Storage
Harvest Season
Year-round. Freshwater pearls from China are the most common source for pearl powder. Saltwater pearls (South Sea, Akoya) are also used but are more expensive.
Quality Indicators
Extremely fine, smooth powder with pearlescent sheen. Should be "micronized" or "ultra-fine" for best absorption. Food-grade or pharmaceutical-grade. Freshwater pearl powder from Zhejiang, China is well-known. Should have no gritty texture between fingers.
Storage
Airtight container, cool dry place, away from moisture. Can be stored for several years.
Safety Information
Contraindications
People with kidney stones (high calcium content - use cautiously)Hypercalcemia (high blood calcium)Pregnancy: generally safe in normal amountsThose on calcium supplements (don't exceed total calcium limits)Children: generally safe in small amountsShellfish allergy (rare - pearls are from mollusks)
Possible Side Effects
- Generally very safe when consumed appropriately
- Excessive intake may cause constipation (high calcium)
- Rare: allergic reaction (shellfish protein)
- Coarse (non-micronized) powder may not be well-absorbed internally
- Note: Ensure you are using food-grade or pharmaceutical-grade pearl powder, not craft-grade
Drug Interactions
- Calcium supplements (additive effect)
- Tetracycline antibiotics (calcium binds to and reduces absorption)
- Thyroid medications (take at different times)
- Bisphosphonates (osteoporosis drugs)
- Iron supplements (calcium reduces absorption)
- Generally moderate interaction potential - separate from other medications by 2-4 hours

Marine Collagen Peptides
Hydrolyzed Collagen (Type I & III)
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.
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.
Marine Collagen Peptides
Hydrolyzed Collagen (Type I & III)
Collagen is the most abundant protein in the human body, making up about 30% of total protein. It is a major structural component of skin, bones, tendons, ligaments, cartilage, and blood vessels. Collagen peptides are hydrolyzed (broken down into smaller amino acid chains) for better absorption. Marine collagen, sourced from fish skin and scales, is the most bioavailable form and is particularly valued for skin beauty benefits.
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.
