Protetite – The Special Bone Calcium

Most conventional calcium supplements on the market are only absorbed at about 10% after ingestion. For example, if you take 1,000 mg, your body may absorb only 100 mg, while the remaining 900 mg stays in the intestines. This residue can lead to side effects such as constipation, diarrhea, bloating, stomach pain, or even intestinal inflammation. Moreover, the 100 mg that enters the bloodstream does not necessarily get deposited in the bones—it travels throughout the body and may accumulate in various tissues. There’s no way to know how much of the calcium you take actually reaches your bones.

Wouldn’t it be better if there were a type of calcium that was highly absorbable and effectively stored in the bones?

Protetite is a special form of calcium that binds with collagen and magnesium, giving it a molecular structure that closely resembles that of human bone. This allows it to be efficiently deposited directly into the bones. Additionally, it is nano-sized, enabling absorption as early as in the stomach. The presence of collagen further enhances the absorption of Protetite, making it even more effective.

3 Key Vitamins for Bone Health (C, D3, K2)

Vitamin C plays a crucial role in the production of collagen, which forms the main framework of bones. This framework acts as a scaffold for minerals to bind and harden into solid bone.

Vitamin D3 is naturally produced by the body when the skin is exposed to strong sunlight. (Many people in Thailand mistakenly believe that morning sunlight is best for producing vitamin D, but in fact, the body synthesizes it most effectively under direct sunlight between 10:00 a.m. and 2:00 p.m., with noon being the optimal time.)
As we age, the skin’s ability to produce vitamin D3 declines due to decreased skin integrity. Additionally, most vitamin D supplements on the market contain vitamin D2, a plant-based form not naturally found in the human body, with low biological activity and minimal impact on increasing vitamin D levels. Therefore, supplements containing vitamin D3 are the better choice, as they help stimulate new bone formation, increase calcium deposition in bones, and reduce bone resorption.

Vitamin K2 is not widely known in Thailand but is highly popular in the U.S., Europe, and Japan. It plays a major role in bone formation, comparable to vitamin D3. It enhances the activity of bone-building enzymes, promotes mineralization both within and around collagen structures, and strengthens bones to make them less prone to fractures. It also suppresses the activity of bone-resorbing cells, helping to reduce bone loss. Moreover, when used in combination with vitamin D3, vitamin K2 helps prevent calcium buildup in the blood vessels, thereby reducing the risk of cardiovascular disease and arterial calcification.

Not Only Calcium, But Many Other Minerals

When we think of minerals essential for bone health, calcium is usually the first that comes to mind, as it is the primary mineral in bones. However, having only calcium is not enough—the body cannot properly build bone, or the bone formed may be weak and brittle.
There are several other minerals that the body also needs, though in smaller amounts, including:

No Hormone, No Bone

While nutrients are indeed necessary for building bones, hormones are the most important factor. Hormones act as the signal that tells the body to start forming bone. Only then do our cells utilize the nutrients available. Without hormones to trigger this process, our cells won’t activate, and the nutrients in the bloodstream remain unused and provide no benefit.

Women after menopause experience rapid onset of osteoporosis due to hormone deficiency—especially those who start with low bone mass, which is like having little savings before retirement. Once work stops, the savings run out quickly. No matter how many supplements are taken, the chance of increasing bone density is very small. Conversely, women who receive hormone replacement therapy show significant increases in bone mass and a clear reduction in fracture risk.

Men do not have a menopause phase, but that does not mean their hormones do not decline. Rather, men’s hormone levels decrease slowly over time without obvious symptoms, unlike women whose hormone levels drop sharply. Many men may not realize they have low hormone levels. Those with a slow and mild decline typically do not develop osteoporosis, but men with very low hormone levels can also suffer from bone problems.

Exercise benefits both men and women. Physical activity stimulates bone formation to compensate for hormone decline and can even increase hormone production—if done with sufficient intensity and duration.
