SIDE EFFECTS:
When taken in accordance with suggested dosages, ashwagandha is usually regarded as safe for the majority of people. However, some people may develop negative side effects such nausea, vomiting, and diarrhea. Ashwagandha can improve thyroid function by boosting the conversion of the less potent thyroid hormone, T4, to the more active form of the thyroid hormone, T3. However, it may interfere with other drugs, including sedatives and thyroid hormone supplements. It is not advised for persons who are about to undergo surgery, are pregnant, are nursing, have autoimmune or thyroid issues, or for those who are taking other medications.
There is evidence that ashwagandha may interact with a number of drugs, including those for high blood pressure, diabetes, immunosuppressants, sedatives, and anticonvulsants (those that prevent seizures).
Ashwagandha should not be used by those with hormone-sensitive prostate cancer since it may raise testosterone levels.
Before ingesting any supplements, it is crucial to speak with a healthcare provider.
Dosage:
Like other dietary supplements, ashwagandha is not subject to FDA regulation.
But you needn’t hazard a guess as to how much to take. Studies have looked at using dosages of varied sizes, but most frequently between 125 and 1,000 mg. With individuals receiving 500 or 600 mg of ashwagandha daily, frequently split into morning and evening doses, many study dosages fall somewhere in the middle.
Your desired health outcome will determine the amount you need to see results. Based on the precise supplement you intend to use and your goals, do some research. Consult your doctor first before beginning any new dietary supplements.
