If a woman is deficient in calcium, she can take calcium carbonate, calcium gluconate and other calcium supplements under the guidance of a doctor. There is no such thing as “what is the best calcium tablet to take”, and it is recommended that you follow your doctor’s instructions for standardized treatment. If a woman needs to supplement calcium, in daily life by more intake of food rich in calcium, protein, vitamins, such as shrimp, kelp, fungus, milk, etc., but also increase outdoor activities, more sunshine. Calcium tablets are used for symptoms such as muscle twitching, tetany, osteoporosis, or calcium supplementation for pregnant and lactating women, menopausal women, and the elderly. Calcium tablets are contraindicated in patients with hypercalcemia, hypercalciuria, calcium-containing kidney stones, or a history of kidney stones. Oral calcium supplements such as calcium carbonate, calcium gluconate, calcium citrate, etc. should be taken as prescribed by the doctor to increase the calcium level in the body. At the same time, attention should also be paid to supplementing other related micronutrients, such as vitamin D₃, osteotriol, cod liver oil and other vitamin D preparations. If a woman is deficient in calcium, she should consult a doctor in a timely manner and standardize her treatment under the guidance of a doctor, rather than blindly taking “calcium tablets” on her own.
