Thorne Zinc Picolinate
Highly absorbable zinc for immune support and mineral repletion
For the 15 mg vs 30 mg choice, read zinc picolinate dosage for men. Thorne Zinc Picolinate provides 15mg or 30mg elemental zinc per capsule in the picolinate form, which has superior absorption compared to zinc oxide or gluconate. NSF Certified for Sport. A foundational mineral supplement for immune support, testosterone maintenance, and correcting mild zinc deficiency common in athletes and those on plant-based diets.

How It Works
Zinc picolinate delivers bioavailable elemental zinc to tissues depleted by sweat, alcohol, stress, or poor dietary intake. Once absorbed, zinc participates in immune cell signaling, hormone synthesis, and DNA repair. Consistent daily dosing maintains tissue zinc pools that aren't stored long-term.
Picolinate Chelation
Zinc bound to picolinic acid (a tryptophan metabolite) facilitates transport across intestinal walls, achieving higher bioavailability than inorganic forms.
Immune Cofactor
Zinc is required for T-cell development, natural killer cell activity, and antiviral interferon signaling.
Hormonal Support
Zinc is a cofactor for testosterone synthesis and thyroid hormone conversion. Deficiency correlates with lower testosterone.
Enzymatic Reactions
Cofactor for 300+ enzymes including antioxidant SOD, DNA repair polymerases, and insulin signaling.
What You'll Experience
Starting
Week 1Take 1 capsule (15mg or 30mg) with food. No acute felt effect. Avoid taking with calcium or iron supplements.
Immune Season
Month 1–3Fewer sick days during cold season is the most commonly reported benefit. Subtle unless you were deficient.
Long-term
Month 3+Maintenance dosing at 15mg/day is sustainable. If using 30mg, consider adding 1–2mg copper to prevent depletion.
Benefits
Superior Absorption
Strong EvidencePicolinate form consistently outperforms oxide and sulfate in absorption studies.
NSF Certified for Sport
Strong EvidenceThird-party tested for banned substances. Trusted by professional athletes.
Immune Support
Moderate EvidenceCorrecting zinc deficiency restores immune competence. Well-established mechanism.
Two Dose Options
Strong EvidenceAvailable in 15mg (maintenance) and 30mg (repletion) strengths.
Risks & Considerations
Copper Depletion
medium riskLong-term 30mg+ zinc without copper supplementation can cause copper deficiency.
GI Nausea
low riskTake with food. Empty stomach dosing commonly causes nausea.
Mineral Competition
low riskSeparate from iron, calcium, and magnesium by 2+ hours for optimal absorption.

SupplementsCreatine Dose: 5g Daily for Muscle, Bone, and Brain
Take 5 g of creatine monohydrate every day for muscle, bone, and brain. You do not need a separate higher daily dose for bone — the bone research is still early and is studied with lifting, at ordinary doses. Some short brain studies use about 10–20 g a day, split up. That is a research protocol, not the daily dose this guide uses. Saturation from 5 g a day is the default.
