The absorption and bioavailability of calcium with CPP
Calcium is the most abundant essential mineral, which human body cannot produce on its own and must be obtained from diet. Many food products such as milk, cheese, yogurt, etc. contain calcium. There are also many calcium supplements and calcium-fortified products in the market. But why do many people still have problems with calcium deficiency?
The reason is that not all of the calcium we consume can be utilized by our body. The average absorption rate is only about 10-40%. Some foods like tea, coffee and carbonated drinks can even reduce the absorption rate of calcium, causing precipitation and forming stones in our body. The absorption and bioavailability of calcium are crucial factors for healthy and strong bones.

Calcium Absorption in the Body
Fact #1
Calcium Absorption Decreases with Age
Calcium is one of the most important minerals in the human body. However, the rate of calcium absorption decreases as we age. The calcium that we need does not work according to the absorption rate. Children typically has an absorption rate of 30-40%, while the absorption rate will drop to about 10% in elderlies.

Growing Stage
The size, length, and density of our bones grows rapidly during childhood and adolescence.
20-25%
Menopause

Late Adulthood
The rate of losing calcium is much faster than absorbing it in elderlies.

Fact #2
Most of the Calcium Can’t Be Effectively Absorbed but Wasted
Once we consume food or supplements, it first enters our stomach. The gastric acid in our stomach solubilizes the calcium in the food and releases calcium ions. At this stage, calcium is in its best state to be absorbed, but unfortunately, absorption does not occur in the stomach.
Calcium is mainly absorbed in the small intestine. As the chyme travels to the ileum, the pH condition becomes more alkaline. Studies have shown that the precipitation of calcium is proportional to the pH value of the environment. Moreover, calcium ions react more readily with phosphoric acid and oxalic acid in alkaline conditions, forming insoluble salts that cannot be absorbed and utilized. Phosphoric acid and oxalic acid are commonly found in many sources, such as coffee, tea, draft beer, carbonated drinks, etc.

Fact #3
Breaking through Your Mineral Absorption Limits
It is negatively charged and has a strong capacity to bind divalent cations (e.g., calcium, magnesium, zinc, iron, etc.). Research has shown that CPP can enhance calcium absorption and increase calcium levels in the blood.
CPP is able to form soluble complexes with minerals, especially calcium, thereby preventing the precipitation of calcium when encountering phosphoric acid and oxalic acid in the intestine, while maintaining a decent calcium absorption efficiency. Hence, CPP could maximize the calcium you intake to be absorbed in the designated place (intestinal epithelial cells). Furthermore, CPP could inhibit osteoclast activity and promote osteoblast proliferation, thereby keeping you away from osteoporosis.
