There are lots of opinions on various alternative treatments and I've found that what seems to work for one PALS is ineffective for another. This has been very frustrating for me.
Opinions on supplements differ, for example. Wikipedia has a whole list of "supplements for ALS" and I do take some of them. Quite a few people believe anything anti-inflammatory can't be bad and might possibly help. There are several anti-inflammatory diets out there and their common thread seems to be lots of fresh organic fruit and veggies, good oils (krill, fish, other Omega 3, and MCT or coconut oil, avocado, etc.). Some people with MS seem to thrive on the ketogenic diet.
One of the things I did was to address any non-ALS related issues, or indirectly related ALS issues and correct them, if possible. I had too much free copper and corrected with Zinc (this doesn't work for everyone), my iron level was extremely low so I supplemented with iron. My thyroid was underactive so I used iodine and that corrected after only one month. I had vitamin and mineral analysis, along with a gut bacteria analysis. After that I started taking a probiotic. Giving up processed food and sugar helped me. I eat tons of fresh fruit so I don't miss the sugar.
At the last support group someone got total relief from constant pain through acupuncture. That's on my list.
I wish there were a standard protocol that worked for all of us.
