Vitamin C Daily Immune Support

Category: Allergy

Vitamin C is the primary water soluble antioxidant in respiratory mucosa. At doses above the RDA, it significantly accelerates histamine catabolism, reduces mast cell degranulation sensitivity, and regenerates glutathione in airway epithelium.

Traditional uses & benefits

• Hay fever, allergic rhinitis, histamine burden, recurrent respiratory illness

Ingredients

• Vitamin C (ascorbic acid or sodium ascorbate) (1000 mg)

How to prepare

1. For allergy support: take 1000mg vitamin C with breakfast and 1000mg with dinner — 2g total daily. This is the dose range where antihistamine effects are observed. 2. Choose buffered vitamin C (calcium ascorbate or sodium ascorbate) if standard ascorbic acid causes stomach upset. 3. Combine with quercetin 500mg twice daily if available — it inhibits mast cell degranulation and synergises with vitamin C. 4. For acute allergy flare: doses up to 3–5g daily are used short-term (1–3 days). Build up gradually to find personal bowel tolerance. 5. Take with food if you are prone to iron overload — vitamin C significantly enhances iron absorption. 6. Long-term: 1–2g daily is sustainable and well-studied. Mega-doses should only be used under supervision.

Why it works

DAO cofactor accelerating histamine catabolism; mast cell stabilisation; mucosal glutathione replenishment

Time to effect

Sustained allergy relief with consistent 4 to 8 weeks use

Not right for

Not the right fit if any of these apply to you: haemochromatosis, kidney stone history (oxalate). When in doubt, check with your pharmacist or GP first.

When to take it

both

Common mistakes

• Taking a single large daily dose — vitamin C has a short half-life; smaller more frequent doses maintain higher blood levels
• Expecting to avoid colds entirely — vitamin C shortens duration, not necessarily frequency
• Using megadose (>2g) long-term without medical supervision — may cause kidney stones in susceptible individuals
• Relying on vitamin C alone without adequate sleep and diet

Sources

• Vitamin C and histamine metabolism (1992): Demonstrated inverse relationship between plasma vitamin C and histamine — supplementation significantly reduced plasma histamine.
