Vitamin C (Liposomal) vs Zinc Picolinate

Mechanism

Ascorbic acid is an essential electron donor and cofactor for numerous enzymatic reactions. It is required for collagen synthesis (prolyl and lysyl hydroxylases), carnitine biosynthesis, catecholamine synthesis (dopamine beta-hydroxylase), and alpha-ketoglutarate-dependent dioxygenases including HIF-prolyl hydroxylases and TET methylcytosine dioxygenases (epigenetic regulation). It regenerates oxidized vitamin E, supports immune function via neutrophil chemotaxis, phagocytosis, and lymphocyte proliferation. Liposomal delivery bypasses SVCT1/2 transporter saturation, achieving plasma levels closer to IV administration.

Standard Dosing

1000-2000mg liposomal vitamin C daily

Timing

Divided doses throughout the day (every 4-6 hours) for optimal plasma levels. Away from high-dose minerals.

Cycle Duration

ongoing

Side Effects

• Diarrhea/GI upset at high non-liposomal doses (bowel tolerance)
• Kidney stone risk (oxalate pathway)
• False blood sugar readings on glucometers
• Dental erosion (chewable forms)

Contraindications

• Hemochromatosis (enhances iron absorption)
• G6PD deficiency (high-dose IV can cause hemolytic anemia)
• History of calcium oxalate kidney stones (may increase oxalate at high oral doses)
• Renal insufficiency (accumulation risk)

Mechanism

Zinc is a cofactor for >300 enzymes and is a structural component of >2000 transcription factors (zinc finger proteins). It is essential for: immune function (T-cell maturation, NK cell activity, neutrophil function), DNA synthesis and repair, protein synthesis, wound healing, taste/smell perception, insulin storage and secretion (zinc-insulin hexamer in beta cells), testosterone synthesis (cofactor for 17-beta-hydroxysteroid dehydrogenase), and antioxidant defense (Cu/Zn-SOD, metallothionein induction). Picolinate chelation via picolinic acid (a tryptophan metabolite) enhances intestinal absorption via DMT1 transporters.

Standard Dosing

15-30mg elemental zinc (as zinc picolinate) daily

Timing

With food to minimize nausea. Separate from iron, calcium, and copper supplements by 2 hours. NOT with high-phytate meals.

Cycle Duration

ongoing (with copper balance — see notes)

Side Effects

• Nausea (especially on empty stomach)
• Metallic taste
• Copper depletion (chronic high-dose without copper)
• Headache
• GI upset
• Reduced HDL at very high doses

Contraindications

• Copper deficiency (zinc will worsen it)
• Concurrent penicillamine therapy without separation
