Climbing and training for climbing really hard, pushing your limits, definitively means you are “tearing down” your body, so that it can rebuild it self even stronger than it was. In doing so you are going to have inflammation, and Physivantage Redux HP helps immensely with aiding in the reduction of harmful effects from inflammation, muscle, connective tissue, and joint pain challenges. It’s good to have pain, because pain is a warning that you need to pay attention, Physivantage Redux HP doesn’t “mask” pain like Ibuprofen or other pain relievers, it aids in the reduction of the things mentioned earlier that cause pain, Redux HP helps you recover and helps you perform, almost like a lubricant in a machine. At age 60 I am in the game and feeling darn good with Redux HP in my regime. I am not a scientist or expert on the nutritional/physiological interaction, I'm trying to use language that I think best describes what I experience from Redux HP. cheers!
