Get StartedDosing
The below doses are based on scientific research, publications, traditional use, or expert opinion. Many herbs and supplements have not been thoroughly tested, and safety and effectiveness may not be proven. Brands may be made differently, with variable ingredients, even within the same brand. The below doses may not apply to all products. You should read product labels, and discuss doses with a qualified healthcare provider before starting therapy.
Adults (over 18 years old)
Common forms of ginger include fresh root, dried root, tablets, capsules, liquid extract, tincture, and tea. Many publications note that the maximum recommended daily dose of ginger is 4 grams. It is believed that the mild stomach upset sometimes caused by ginger may be reduced by taking ginger capsules rather than powder.
Many experts and publications suggest that ginger powder, tablets, or capsules or freshly cut ginger can be used in doses of 1 to 5 grams daily, by mouth, divided into smaller doses.
Children (under 18 years old)
There is insufficient scientific evidence to recommend the use of ginger in children.
