Rating (out of 5): 3

Amino acid chelates are minerals (such as calcium, magnesium, or zinc) bound to amino acids to enhance absorption in the digestive tract. The concept is scientifically validated, especially for minerals that are crucial to bone health. Studies have shown that chelated forms of minerals can improve bioavailability compared to inorganic salts, which means the body absorbs and utilizes them more effectively. For example, calcium amino acid chelate has been found in some research to lead to higher blood calcium levels and increased bone mineralization compared to calcium carbonate or citrate, particularly in populations with low stomach acid or absorption issues.

The scientific evidence specifically supports the use of chelated forms of bone-related minerals (like calcium and magnesium) in supplements intended to support skeletal health. However, the body of evidence is moderate; while bioavailability is improved, the impact on clinically meaningful outcomes (such as fracture risk reduction or significant increases in bone density) is less well-established and often depends on the population studied. The mechanism is plausible and supported by absorption studies, but large, long-term clinical trials are less common.

Overall, using amino acid chelates to deliver bone-supporting minerals is grounded in science, but the direct benefits for skeletal outcomes are supported by moderate-quality evidence.
