Think of Calcium Bisglycinate as your body's most friendly and absorbable calcium - a fully chelated mineral where each calcium ion is bonded to two glycine molecules. This unique structure protects calcium from forming insoluble complexes in the gut, allowing superior absorption without digestive upset.
We produce Calcium Bisglycinate through a patented chelation process using high-purity glycine and calcium sources. The result is a fine, white powder with neutral taste, excellent stability, and high bioavailability. Designed for premium bone health, prenatal nutrition, and sensitive stomach formulas, our Calcium Bisglycinate bulk powder delivers calcium effectively - no chalkiness, no constipation, just results.

Benefits of Calcium Bisglycinate Powder
Highly Bioavailable Calcium
Uses glycine transporter pathway for absorption - up to 2x more calcium reaches your bloodstream compared to carbonate.
01
Bone Health & Density
Supports peak bone mass in youth and slows age-related bone loss in older adults.
02
Gentle on Digestion
No need for stomach acid. Non-constipating, no bloating, no gas - ideal for sensitive individuals.
03
Prenatal & Women's Health
Supports fetal skeletal development and reduces muscle cramps during pregnancy.
04
Muscle & Nerve Support
Ensures steady calcium delivery for muscle contraction and nerve signaling without spikes or side effects.
05
Application Fields
Dietary Supplements: Tablets, capsules, chewables, gummies, and powders for daily bone health - especially for those who cannot tolerate carbonate or citrate.
Prenatal & Pediatric Nutrition: Gentle enough for pregnancy and children's calcium needs. Often combined with Vitamin D3 and Magnesium.
Sports Nutrition: Helps prevent exercise-induced cramps and supports bone remodeling in athletes. Neutral taste ideal for intra-workout powders.
Medical Nutrition & Elderly Care: For patients with malabsorption, hypochlorhydria, or chronic kidney disease (non-phosphate binder use). Easy on the stomach and reliably absorbed.
Functional Foods & Beverages: Fortified plant-based milks, protein shakes, nutritional bars, and drink powders without chalky texture or off-taste.
Production Process
Product Quality Advantage
High Purity & Potency: ≥98% pure, with each gram delivering consistent calcium content - no variance, just reliable mineral support.
Excellent Stability: Calcium Bisglycinate is inherently stable, non-hygroscopic. We use moisture-controlled packaging to maintain potency over 24+ months.
Superior Bioavailability: The glycine chelate protects calcium from interference by phytates, oxalates, and other inhibitors. Absorption is significantly higher than carbonate or citrate.
Gentle on Stomach: Neutral pH and chelated form eliminate common side effects like bloating, gas, and constipation - perfect for sensitive individuals.

FAQ
Q: Why choose Calcium Bisglycinate over Calcium Carbonate or Citrate?
A: Calcium carbonate requires stomach acid and often causes constipation. Calcium citrate is better but still can cause mild GI issues. Calcium Bisglycinate is fully chelated, absorbed via amino acid pathways, and causes virtually no digestive side effects - ideal for sensitive individuals, elderly, and those on acid-reducing medications.
Q: Is Calcium Bisglycinate stable in supplements?
A: Yes. It is highly stable, non-hygroscopic, and compatible with most excipients. With proper dry storage, our powder maintains potency for 24+ months.
Q: Who needs Calcium Bisglycinate supplementation?
A: Anyone needing calcium but experiencing side effects from other forms: post-menopausal women, elderly, people with low stomach acid, IBS, constipation-prone individuals, and pregnant women.
Q: How much elemental calcium does Calcium Bisglycinate contain?
A: Approximately 20% elemental calcium by weight. For example, 1000 mg of Calcium Bisglycinate provides ~200 mg of elemental calcium.
Q: What is the recommended dosage?
A: Typical supplemental dose: 500–1000 mg elemental calcium per day, divided. For Calcium Bisglycinate powder: 2.5–5 grams daily. Always consult a healthcare provider.
Q: Can you blend Calcium Bisglycinate with other minerals?
A: Absolutely. It pairs very well with Magnesium Bisglycinate (same chelate form), Zinc Bisglycinate, Vitamin D3, and Vitamin K2. We offer custom blends and formulation assistance.
