See if you have these symptoms. If there is, it is calcium deficiency.
Calcium deficiency requires calcium supplementation. At present, in addition to getting more sunshine, calcium supplementation is also needed.
There are only two ways to supplement calcium.
The first is the most direct calcium supplement: if you choose calcium, you should pay attention to choosing calcium with good source, high content and easy absorption, such as the edge of calcium. Absorption is an important problem, and it is useless to make up too much.
The second is food supplement: there are many foods rich in calcium, such as shrimp, hairy crabs, vegetables, milk and so on.
Soybeans, tender tofu, green beans, fried pumpkin seeds and pork floss are all calcium-rich foods, especially milk.
It should also be noted that children need calcium supplementation every day. People need calcium supplements at different stages of their lives, not after a week or two. This needs special reminder.
