I take 100 mg a day of co-enzyme Q 10 but - ask your doctor or other medical provider, but I have safely taken 300 mg and more- you may need to adjust the amountbut I'm not a Doctor. This site suggests 100 - 200 mg a day but you may want to look into dosing further to get the right amount for pain relief as I feel safe from my research taking 300 mg a day or more but I am NOT a doctor so you have to research dosing but mentioning this in case 100 mg isn't enough for your pain. Feel better.

Hello @ramakambhatla,

Thank you for sharing your information and insights. I've been reading your messages with interest, more so because I'm also originally from India.
Coenzyme Q10 (CoQ10) has been widely available in India for a number of years now, at local pharmacies (or chemists, as we tend to say:) and online. However, as @stressedmesseddepressed also noted, I would like to add that Mayo Clinic advises that people consult with their current care provider before making any changes to their existing medication or treatment plan.
CoQ10 supplements may benefit some patients with cardiovascular disorders, but research is not conclusive; for instance, CoQ10 might make blood-thinning drugs, such as warfarin (Coumadin, Jantoven), less effective; and this could increase the risk of a blood clot. https://www.mayoclinic.org/drugs-supplements-coenzyme-q10/art-20362602?pg=2
