Calcium Ascorbate Powder

Buffered, non-acidic vitamin C — gentle on the stomach

28,00 € TTC
Pharmaceutical Grade GMO-Free Vegan Gluten-Free

Calcium ascorbate is the calcium salt of L(+) ascorbic acid. This buffered form retains the full activity of vitamin C without its acidity: in solution its pH is close to neutral (around 7), whereas pure ascorbic acid drops to about 2.5.

It is the reference form for anyone who wants higher vitamin C intakes without gastric discomfort, and who wishes to protect tooth enamel during prolonged daily use.

Each gram of powder provides approximately 890 mg of vitamin C and 100 mg of calcium — that is 1,113% of the NRV* for vitamin C and 12.5% of the NRV for calcium.

  • ⚪ Non-acidic vitamin C — neutral pH in solution
  • 🫄 Better tolerated by sensitive stomachs
  • 🦷 Gentle on tooth enamel
  • 🇪🇺 Made in Europe — pharmaceutical grade

Benefits

  • Contributes to the normal function of the immune system
  • Contributes to the reduction of tiredness and fatigue
  • Contributes to the protection of cells from oxidative stress
  • Contributes to normal collagen formation
  • Increases iron absorption
  • Calcium contributes to normal muscle function and to the maintenance of normal bones

How to use

Take 1 g per day (about 1/4 teaspoon), dissolved in a glass of water or fruit juice. The powder dissolves quickly and tastes neutral, very slightly saline — without the sourness of standard vitamin C.

The daily amount may be split across several servings. Do not exceed the recommended daily dose.

Food supplement. Not a substitute for a varied, balanced diet and a healthy lifestyle. Keep out of reach of young children. Not recommended without medical advice for people on a low-calcium diet or prone to kidney stones.

The vitamin C molecule is identical. The difference is pH: ascorbic acid is acidic (pH around 2.5 in solution), calcium ascorbate is neutral (pH around 7). Same vitamin C outcome, but without heartburn or enamel erosion. In exchange, calcium ascorbate also supplies calcium, which matters if you already supplement it.
About 100 mg of calcium, i.e. 12.5% of the NRV. That is moderate: recommended intakes are around 800 mg per day and the EFSA upper safe level is 2,500 mg. If you already take a calcium supplement or follow a low-calcium diet, ask your doctor.
No — that is precisely the point of this form. The taste is neutral, very slightly saline. Many people who could no longer tolerate the sourness of pure ascorbic acid switch to calcium ascorbate for this reason.
No. Ester-C® is a patented preparation based on calcium ascorbate with added metabolites (including threonate). Our product is pure calcium ascorbate, with no additives or added metabolites — the simple buffered form, with a fully transparent composition.
In its resealed pouch, away from light, heat and moisture. Calcium ascorbate is markedly more stable than pure ascorbic acid but remains moisture-sensitive: reseal carefully after each use.
