Zinc

Complete Ingredient Profile
Ingredient Name & Common Synonyms
Primary Name: Zinc (as Zinc Bisglycinate)
Common Synonyms: Zinc chelate, Zinc glycinate, Elemental zinc
Chemical Classification: Essential trace mineral, Chelated mineral
Molecular Formula: C₄H₈N₂O₄Zn
Overview
Botanical Family: Naturally occurring in Brassicaceae (seeds), Fabaceae (legumes), Poaceae (grains)
Primary Origin: Oysters, beef, pumpkin seeds, chickpeas, cashews, quinoa
Extraction Method: Chelation process binding zinc to glycine amino acids for enhanced absorption
Molecular Structure: Zinc ion bound to two glycine molecules forming stable chelate complex
Appearance: Light tan to beige powder, nearly odorless with mild metallic taste
Benefits & Uses
For Women's Hormonal Health:
- Hormone Synthesis: Zinc is essential for the production and regulation of key hormones including testosterone, estrogen, and progesterone
- PCOS Support: Zinc supplementation helps improve insulin sensitivity and reduces inflammation associated with PCOS
- Reproductive Health: Critical for ovarian function, egg quality, and maintaining healthy menstrual cycles
Primary Health Benefits:
- Immune Function: Essential for development and function of immune cells (T-cells, NK cells) and immune system response
- Antioxidant Support: Component of superoxide dismutase, protecting cells from oxidative damage and free radicals
- Wound Healing: Critical for collagen synthesis, tissue repair processes, and cellular regeneration
- Growth & Development: Required for normal growth, development, cellular reproduction, and protein synthesis
Mechanism of Action:
- Enzyme Cofactor: Essential component of metalloenzymes throughout the body for catalytic functions
- Gene Expression: Regulates transcription factors and gene expression for immune and metabolic pathways
- Cell Signaling: Functions as a signaling molecule in immune and metabolic pathways
- Membrane Stability: Maintains cellular membrane integrity and supports cellular transport processes
Safety & Warnings
General Safety Profile:
Zinc bisglycinate is well-tolerated with superior absorption compared to other zinc forms. Our 5mg dose provides optimal support without risk of toxicity.
Dosage Safety:
- Standard Dosage: 8-11mg daily recommended intake for adults
- Orbelli Dosage: 5mg per serving provides 45% of the daily value
- Maximum Safe Dose: Up to 40mg daily is considered the upper limit for long-term use
Potential Side Effects:
- Digestive Effects: High doses may cause nausea, vomiting, or stomach upset
- Copper Interference: Excessive zinc can interfere with copper absorption
- Throat Irritation: May cause mild throat irritation in some individuals - this is normal and typically resolves quickly
Important Warnings:
Mineral Balance: Avoid exceeding the recommended dose to prevent mineral imbalances
Drug Interactions: May reduce the absorption of certain antibiotics and medications
Empty Stomach: Taking on an empty stomach may increase nausea risk
Consult a healthcare provider if taking medications or having digestive conditions
Recommended Patch-Test Instructions:
Not applicable for oral supplements. For topical applications containing zinc, perform a 48-hour patch test on the inner forearm.
Formulation Tips
Physical Properties:
- pH Range: 6.0-7.0 (neutral in aqueous solution)
- Solubility: Highly soluble in water due to the chelated form
- Stability: Stable across a wide pH range, heat-stable up to 200°C
- Absorption: Superior bioavailability compared to zinc oxide or sulfate
Optimal Dosing:
- Therapeutic Range: 5-15mg daily for general health support
- Orbelli Formula: 5mg per serving (optimal absorption dose)
- Bioavailability: Enhanced absorption due to glycinate chelation
- Timing: Can be taken with or without food, better tolerance with meals
Pairing Suggestions:
- Synergistic with: Vitamin C, vitamin A, selenium
- Compatible with: Most vitamins and minerals in appropriate ratios
- Avoid with: High-dose iron or calcium (may compete for absorption)
- Enhanced by: Amino acids and organic acids for absorption
