The recommended daily dosage of turmeric can vary depending on the form in which it is taken and the reason for which it is being taken. For general health, a daily dosage of 500-2000 mg of turmeric powder is considered safe. For specific conditions such as osteoarthritis, a daily dosage of 800-1200 mg of turmeric extract has been used in clinical studies. It is important to note that it is always best to consult with a healthcare provider before starting any new supplement regimen.
