Really entangled with golden hair (4 months), do you want to supplement calcium? If you don't make up, it will affect your development. Too much makeup is not good. There are trace elements, I don't know. You need calcium supplement, but pay attention to the dosage and frequency. Don't blindly think that the more the better. Calcium supplementation should focus on absorption, not dosage. Long-term high-dose calcium supplementation will cause the unabsorbable calcium to deposit on the bone surface, artificially causing bone deformity. To choose a better calcium tablet, generally this kind of calcium tablet contains vitamin D3 to promote the absorption of calcium. If not, it can promote the absorption of calcium and supplement VA. Trace elements and minerals can be supplemented in moderation, but not too much.
