The results on rat may be very different on those on humans.
What do you think will be the maximum (but still achievable) effect of c60 ? And what do you think about the most probable result ?
This is the sixty four thousand dollar question, as they say in the US. I think that it's safe to say that humans will not see a 90% life extension like the rats did. Long lived species like naked mole rats, which are similar in many ways to rats, but live ten times longer, have better endogenous antioxidant protection than rats do. So do we. Since our antioxidant defenses are already pretty good, we will not have as much to gain by improving them. Nevertheless, C60-oo is no ordinary antioxidant. When people first became aware that a lot of aging damage involved free radicals, a craze developed around antioxidants. The problem was, when antioxidants were examined in clinical trials, they didn't look that great. I think that was because the antioxidants we had just weren't the right ones. They had poor pharmacokinetics, tended to not occupy the locations in the body where the free radicals were being generated, and were chemically unstable. Quite a while ago, a Russian scientist by the name of Skulachev designed a molecule that would be attracted to the mitochondrial membrane, and contained a plastoquinone antioxidant group. This was a brilliant concept, and it did show some moderately good results in vivo. When Baati and coworkers dissolved C60 in olive oil, they inadvertently created a molecule that was very much like Skulachev's but with a much better antioxidant. C60 has been called a "free radical sponge" because of the way that it soaks up free radicals, holding them until they can be neutralized. It has been shown to mimic the actions of superoxide dismutase, and the C60-oo adduct has been shown to localize in membranes, particularly the mitochondrial fraction.
I think that with C60-oo, we will finally see the promise of "antioxidants", which many of us had essentially given up on. As to how many years it might add to human lifespans, I could only speculate. There are other processes involved in aging, like systemic amyloidosis, that will probably cap the typical lifespan at far less than the 150 years that a direct extrapolation from the rats would suggest. Based on what we've seen in humans so far, C60-oo is looking like a wonder drug for people with inflammatory problems, problems with oxygenation, and mitochondrial dysfunction. It could have a very important role in a lot of disease states- for example, if I was suffering from congestive heart failure, I would take C60-oo in a heartbeat, assuming I still had one. There are reasons to believe it would be helpful in MS, CFS, fibromyalgia, and asthma, and autoimmune disorders in general. We have two members of our community who are taking it for ALS, and one with MS. Oxidative stress is involved in telomere attrition, as well as a number of other problems. Chronic inflammation also leads to a great deal of damage. By acting on these fronts, it's hard to imagine that C60-oo would not provide a significant life extension to humans, but the magnitude of it is anyone's guess.
