Alka-C Complex — Alkaline-Buffered Vitamin C Powder (5.87 oz)
Alka-C Complex provides vitamin C in a multi-mineral alkaline buffer system — combining ascorbic acid with calcium, magnesium, and potassium to create a physiologically pH-neutral vitamin C complex.* This alkaline formulation is the gold standard for individuals who need high therapeutic doses of vitamin C but cannot tolerate the acidity of standard ascorbic acid.* The powder format allows maximum flexibility in dosing and administration.*
Key Benefits
- Alkaline-buffered vitamin C — neutral pH for maximum GI tolerance at any dose*
- Multi-mineral buffer: calcium, magnesium, and potassium provide additional electrolyte benefit
- Supports immune function, antioxidant protection, and collagen synthesis at therapeutic doses*
- Ideal for high-dose vitamin C protocols without GI discomfort
- Powder format — versatile, easy to mix, flexible dosing
Who Is This For?
Alka-C Complex is perfect for anyone pursuing high-dose vitamin C therapy (4–10g/day for acute illness or cancer support protocols), individuals with acid reflux, GERD, or sensitive stomachs, those in post-surgical recovery needing intensive collagen and immune support, and practitioners using vitamin C as a cornerstone of natural medicine protocols.

Frequently Asked Questions
Q: Why choose alkaline-buffered over liposomal vitamin C?
A: Alkaline buffered vitamin C allows very high doses with excellent GI tolerance and provides mineral co-factors. Liposomal vitamin C provides superior cellular uptake at moderate doses. For high-dose immune protocols, buffered powder is often the most practical approach.
Q: What's the therapeutic dose?
A: Bowel-tolerance dosing for vitamin C is individualized — starting at 1-2g per dose, increasing until loose stools, then backing off by 10-20%. Critically ill individuals may tolerate much higher doses.
Q: Is this the same as sodium ascorbate powder?
A: No — sodium ascorbate uses sodium as the sole buffer. Alka-C uses calcium, magnesium, and potassium — providing more complete mineral co-factors and avoiding sodium loading.
