Curcumin/turmeric has been a part of my pre-pack right from the start ( I use curcumin with black pepper, so the absorption of the active ingredient is much better)
I also add some curcumin and black pepper to my daily breakfast ( actually, I add them into my cereals, along with blueberries, raspberries, and pumpkin seeds).
Last week, on vacations, I didn't had any curcumin for a week. I do not know if it is because of the very high humidity in Mexico, or because of the lack of curcumin, but by the end of the week, I had some minor joint pain, in particular in the index of my right hand ( maybe because of my badminton playing style - I often feel some stiffness the morning after playing, but no pain). I never had pain in that joint before. After 2 days back here, the pain was entirely gone. Usually, cold weather is not good for joints pain, so I wonder if it is the curcumin, a good, natural, anti-inflammatory, that has made the difference.
Anyway, peppered curcumin sure helps me with POIS, and is a very valuable part of my pre-pack, having several positive properties ( (IDO inhibitor , anti-inflammatory, antioxidant, mast cells stabilizer, anxiolytic ). It works good for me, so it must help or compensate for one or more of my metabolic flaws.
