Benefits

Ester-C is a calcium ascorbate derivative designed for enhanced absorption and retention of vitamin C in the body, supporting sustained antioxidant activity.

  • Helps strengthen Immunity through prolonged release of vitamin C, ensuring ongoing immune support.
  • Promotes Skin Health by maintaining collagen integrity and reducing inflammatory damage.
  • Contributes to General Health by protecting cells from oxidative stress over extended periods.
  • May aid in Anti-Aging by providing steady antioxidant levels to combat cellular aging.

Dosage

Ester-C supplement is typically taken in doses depending on individual needs and health goals:

  • Gentle and sustained Vitamin C: 500–1000 mg/day of Ester-C (calcium ascorbate + metabolites).
  • Benefits: Less acidic, longer retention in cells, often better tolerated.
  • Calcium content: Contributes ~50–100 mg calcium per dose.
  • Recommendation: Take with meals for optimal absorption and minimal discomfort.
Ester-C dosage should be tailored by a healthcare professional to your condition.

Side Effects

Ester-C® is a patented calcium ascorbate formula, offering buffered vitamin C support but may still cause mild effects. Watch for:

  • Possible gastrointestinal upset—nausea or loose stools—especially at high doses
  • Mild headache or dizziness in sensitive individuals
  • Occasional mild hypercalcemia symptoms—fatigue or constipation—at very high intake
  • Rare skin rash or itching—hypersensitivity reactions
  • Temporary mild increase in blood pressure due to calcium load

Interactions

Possible interactions include:

  • Other Vitamin C forms: Ester-C offers buffered release; combining with ascorbic acid can increase tolerance but monitor total C intake.
  • Iron therapies: Similar to ascorbic acid, it boosts iron absorption—coordinate timing with Iron supplementation.
  • Anticoagulants: Monitor INR if taking high-dose C due to mild effects on platelet aggregation.

Precautions

Before using Ester-C®, confirm none of the following apply to you. If they do, consult your healthcare provider:

  • Individuals with hypercalcemia or kidney stones: Monitor calcium status and hydration
  • People with kidney disease or impaired renal function: Use under supervision—risk of calcium accumulation
  • Those on calcium channel blockers or other calcium-affecting medications: Monitor interactions
  • Pregnant or breastfeeding women: Generally safe at recommended levels; avoid excessive doses without advice
  • Patients scheduled for surgery: Discontinue at least two weeks prior—possible anesthesia and electrolyte interactions

Studies

These studies provide scientific insights into Ester-C benefits:

A 2020 RCT in 100 older adults showed 500 mg/day Ester-C for 8 weeks maintained higher leukocyte ascorbate levels post-exercise versus standard vitamin C (P < 0.05), though infection rates were unaffected.

No large-scale trials

have evaluated Ester-C for cold prevention, wound healing, or skin aging in humans.

While marketed for non-acidic delivery, clinical advantages over other ascorbate forms remain unproven.
