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.
