Calcium tablets and milk are both calcium supplements, but there are slight differences in calcium supplementation between the two. For adolescents who have significantly low calcium ions, or who are growing too fast, and for elderly people who have more serious calcium loss, calcium tablets can be added daily for calcium supplementation. Milk is mainly for those who do not have significant calcium loss, calcium ions are normal, and increasing the intake of calcium ions through milk in daily life will have more relative health effects. Calcium tablets is the therapeutic effect and calcium supplementation is slightly stronger. If calcium deficiency or relative calcium deficiency occurs for adolescents and the elderly, oral treatment with calcium tablets is recommended. If for young adults or no obvious calcium ion deficiency, you can daily oral milk for calcium health care, so both can be calcium supplements, but slightly different.
