Curcumin as mentioned is great. If you go oral route you want an extract standardized for 95% curcuminoids, and you want to take 20-30mg Bioperine with it to enhance absorption. 500-1,000mg eod to daily depending on needs vs goals.
Pine bark extract is a great antioxidant that helps support kidney health and increases ejection fraction rate of the heart. It decreased incidences of blood clots in airplane travelers in conjunction with nattokinase better than either compound solo did. Truckers often take it for improved leg circulation during their long hauls seated. Good for the cardiovascular system.
Injectable glutathione at 1-200mg daily will lower inflammation and improve kidney & liver health, or a bolus dose of 4-800mg once a week before bedtime will really acutely improve recovery. I say before bedtime because 3ccs of glutathione is going to ache some until you go to sleep, so pin it & try to pass out.
