I think supplements can help in combination with a proper diet for the immune system whatever the illness is and may eventually maintain a certain level of improvement for those that have some other underlying condition to deal with. I imagine with anything, supplements, antifungals, parasite cleanses, that unless the underlying cause that allowed these things to flourish in the first place will of course no doubt relapse at some point after stopping ongoing treatment. Supplements are usually (for me) rather ineffective unless done in combination with the diet, because the body will not even be able to absorb them and make proper use unless the body is strong enough to start absorbing nutrients again. So they can be somewhat...useless until that is fixed up.

I've done a parasite cleanse, I have also used antifungals before, I've used supplements before, but unless I stick with a specific diet, I'm a gonner. If I go off the diet, I'm a gonner. So it's all I have for now because I live with an ongoing virus that never leaves, plus other possible infections (jawbone).

THere are people on candida forums who go on the diet, take antifungals and supplements and start feeling really well and sometimes that healing can last even after they relax the diet a bit. They are usually the ones who may have had a temporary health setback and developed yeast in the process. Treating yeast might then result in lasting improvements or even a cure and they're back to normal again. But those like myself, or with other underlying conditions who have candida as a result, are the ones who constantly relapse whenever they go off treatment. Unless in the process the underlying condition has actually been able to heal from proper diet and treatment (which is a bonus). Mine unfortuantely does not do that and I imagine those with severe mercury poisoning may not either, though it does help. It also takes the body a long time to heal and a long time to re-establish proper good bacteria apparently (months on end), so that's another thing. I had antibiotics more than a year ago and now my diet cheats are devastating and it takes many weeks now to get back on track.
