Himalaya Speman Tablets are an Ayurvedic supplement, and the dosage should be taken only as advised by your doctor because the right amount depends on your health condition and any other medicines you may be using. It is generally well tolerated when used as directed, but response can vary from person to person due to individual tolerance and other factors. If you have any health concerns, it is best to consult a doctor before using it, as self-medication may delay proper diagnosis or treatment.
