How long after taking a charcoal supplement would one be able to take other supplements or meds if needed? My general thoughts are 4 hours but im just guessing?? Im only looking at doing this once maybe twice a week as a part of my program to lower ammonia which is a neurotoxin produced by viruses bacteria and in the gut. Im also using the herb yucca which is suppose to also help absorb ammonia to be expelled as well as using OKG which recycles ammonia into glutamine and lowers ammonia that way. Be greatful for an answer or any other ways people have used charcoal to remove ammonia or detox etc. cheers!!
