- Pregnant women: 11 mg
- Lactating women: 12 mg
Dosing of different forms of zinc (e.g., zinc gluconate, zinc citrate)
Zinc is available in several different forms, such as zinc gluconate and zinc citrate. Different forms can affect absorption and effectiveness.
Generally, zinc gluconate is a popular form because it is well absorbed. The dosage varies, but a typical amount is 15-30 mg per day. Zinc citrate may be an alternative, especially for those who experience stomach issues with zinc gluconate.
Possible side effects of excessive zinc intake
Excessive zinc intake can cause several side effects, such as nausea, vomiting, and diarrhea. Prolonged overdose can also lead to impaired copper absorption, which can cause anemia.
Generally, over 40 mg per day is considered excessive for adults. It is important to adhere to recommended dosages and consult a doctor before starting supplements.
Zinc absorption and optimization
Zinc absorption can vary depending on diet and other nutrients. For example, excessive calcium or iron intake can hinder zinc absorption.
To improve zinc absorption, it is advisable to take zinc on an empty stomach or with protein-rich foods. Fermented foods can also enhance absorption.
Additionally, if you are using zinc supplements, choose a form that is easily absorbed, such as zinc gluconate or zinc citrate, and avoid large amounts of fiber-rich foods at the same time, as they can bind zinc and reduce its absorption.
What are the benefits of zinc for the immune system?
Zinc is an important mineral that supports the immune system and helps the body fight infections. Adequate intake can shorten the duration of colds and improve overall health.
Zinc’s effect on the duration of colds
Zinc can shorten the duration of colds and reduce the severity of symptoms. Studies have shown that taking zinc at the onset of a cold can reduce the length of illness by up to 30 percent.
It is advisable to start taking zinc as early as possible when cold symptoms appear. The general dosage is about 10-15 mg per day, but it is important to follow recommendations and avoid excessive use.
