Vitamin C is best taken orally in the morning in the human body for best results. Vitamin C is not synthesized in the human body and must be ingested through outside sources. Personally, I think the best way to ingest vitamin C is through vegetables and fruits, but also in health products. vitamin C is of great significance to the human body and should be taken every day, including correcting anemia, detoxifying, preventing cancer, and scavenging free radicals, all of which are very effective. The latest research on vitamin C believes that it can be anti-aging and can prevent tumor formation, which is of great value to modern health, but it is not recommended to eat large amounts unless the body is poisoned, such as lead poisoning, mercury poisoning and other heavy metals after long-term exposure, you can take a large amount of vitamin C orally, which can make the toxins out of the body.
