1 The good solubility of calcium lactate
2 The calcium lactate is derived from natural lactic acid and naturally occurs in the human body.
3 The bioavailability of bio-lactate calcium (the amount of nutrients that can be absorbed by the body) is high: Absorption rate of calcium in human body sequence: calcium lactate> calcium gluconate> calcium carbonate> calcium phosphate
4 lactate calcium has a good taste, neutral pH, and The smallest concentration of calcium lactate that can be perceived after different calcium sources are dissolved in water is the largest. The details as below:
| Calcium source （25℃） | Solubility（g/100ml） | The content of calcium（g/100ml） | Benefits |
| Calcium lactate | 9.3 | 1.27 | High solubility, high absorption rate, right price |
| Calcium gluconate | 3.5 | 0.33 | More expensive, less soluble, less bioabsorbable than calcium lactate |
| Calcium Citrate | 0.2 | 0.04 | Low solubility, low bioabsorption, high hygroscopicity |
| Calcium phosphate | <0.1 | – | Low price, very low solubility, inorganic salts |
| Calcium tartrate | <0.1 | – | Very low solubility |
| Calcium carbonate | <0.1 | – | Low price, very low solubility, inorganic salts |
Comparison of flavors：
| Calcium lactate | No taste/neutral taste almost |
| Calcium gluconate | Soft taste |
| Calcium Citrate | sour |
| Calcium carbonate | Creamy/Lemon Flavor |
