Vitamin C (Liposomal) vs Vitamin E (Mixed Tocopherols/Tocotrienols)

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

Vitamin E family comprises 4 tocopherols (alpha, beta, gamma, delta) and 4 tocotrienols. Alpha-tocopherol is the primary lipid-soluble, chain-breaking antioxidant in cell membranes, intercepting peroxyl radicals to halt lipid peroxidation. Gamma-tocopherol uniquely traps reactive nitrogen species (peroxynitrite). Tocotrienols have additional properties: inhibition of HMG-CoA reductase (cholesterol lowering), NF-kB suppression, induction of apoptosis in cancer cells, and neuroprotection. The full spectrum provides synergistic antioxidant, anti-inflammatory, and cell signaling functions.

Standard Dosing

200-400 IU mixed tocopherols + 50-100mg tocotrienols daily

Timing

With fat-containing meal.

Cycle Duration

ongoing

Side Effects

• GI upset at high doses
• Fatigue
• Headache
• Blurred vision (rare)
• Increased all-cause mortality signal at >400 IU synthetic dl-alpha-tocopherol in meta-analyses

Contraindications

• Vitamin K deficiency or warfarin therapy (at high doses)
• Scheduled surgery (discontinue 2 weeks prior at >400 IU)
• Retinitis pigmentosa (alpha-tocopherol contraindicated in some forms)
