Vitamin C

Vitamin C intolerance may arise from its acidic nature, synthetic formulations, or excessive intake. By choosing whole-food sources, monitoring dosage, and using gentler supplement forms, you can support your health while avoiding adverse reactions.

🍊 What is Vitamin C?
Vitamin C, also known as ascorbic acid, is a water-soluble vitamin essential for immune function, collagen production, and overall antioxidant protection. It plays a crucial role in wound healing, iron absorption, and maintaining healthy skin. While commonly found in citrus fruits, berries, and vegetables, some individuals may experience intolerance or adverse reactions, especially from high doses or synthetic supplements.

🤔 Why Do I Have an Intolerance to Vitamin C?
Vitamin C intolerance can result from digestive issues, metabolic factors, or excessive supplementation.

• Acidic nature – High doses of vitamin C can cause acid reflux, gastritis, or stomach irritation.
• Digestive sensitivity – Some individuals experience bloating, diarrhea, or cramping from excessive intake.
• Synthetic vs. natural sources – Some people tolerate vitamin C from whole foods better than from supplements.
• Oxalate formation – Excess vitamin C can convert to oxalates, increasing the risk of kidney stones in susceptible individuals.

🛠️ What Can I Do About It?
❌ Limit high-dose supplements – Opt for whole-food sources or buffered vitamin C instead of synthetic ascorbic acid.
📊 Monitor intake – Stick to moderate consumption levels to avoid digestive distress.
🍽️ Take with food – Consuming vitamin C alongside meals can reduce stomach irritation.
💧 Stay hydrated – Drink plenty of water to help flush excess vitamin C and prevent kidney stone formation.
👩‍⚕️ Consult a healthcare provider – If symptoms persist, seek professional advice for proper dosage and alternatives.

💊 Which Supplements Can Help with Chemical Sensitivities?
• Buffered vitamin C – A non-acidic form that’s gentler on digestion.
• Magnesium – Helps balance acidity and supports vitamin C metabolism.
• Probiotics – Improve gut health, reducing potential digestive discomfort.
• Electrolytes – Maintain hydration balance, especially if experiencing diarrhea.
• Quercetin – A plant-based antioxidant that works synergistically with vitamin C.

🌟 Why Might I React to Vitamin C but Not Other Water-Soluble Vitamins?
• Acidic properties – Unlike B vitamins, vitamin C’s acidity can cause gastrointestinal irritation.
• Synthetic vs. natural differences – Some individuals tolerate vitamin C from food but react to supplements.
• Oxalate concerns – High doses can contribute to kidney stone formation, unlike most B vitamins.
• Rapid absorption and excretion – Vitamin C’s fast metabolism can cause fluctuations in tolerance levels.

🍽️ Common Exposure Sources
• Citrus fruits (oranges, lemons, grapefruits)
• Berries (strawberries, blueberries, raspberries)
• Bell peppers (red, yellow, green)
• Leafy greens (spinach, kale, Swiss chard)
• Tomatoes and potatoes
• Vitamin C supplements (ascorbic acid, sodium ascorbate)

🍽️ Alternatives (if tolerated)
• Natural vitamin C sources – Focus on whole foods such as citrus fruits, berries, and leafy greens.
• Liposomal vitamin C – A gentler, fat-encapsulated form that improves absorption.
• Acerola cherry extract – A natural, high-vitamin C alternative with added phytonutrients.
• Rosehip powder – Another plant-based vitamin C source with anti-inflammatory benefits.
