Many here are taking Yucca for ammonia elimination and/or Quinoa for health benefits and getting certain nutrients lost by not eating other foods due to high sulfur or ammonia components. Both of these foods have saponins in them. I've read there are a variety of saponins so I guess the first questions is are certain saponins safer than others? I've also read that Yucca saponins act as a surfactant and cleans the intestines and villi providing better absorption of nutrients. I've read elsewhere that Yucca saponins harm villi. Quinoa saponins can be rinsed from the exterior of the seed but to what extent they are eliminated is questionable. Do Quinoa saponins also help eliminate ammonia? I can certainly attest to the fact that urine smells of less ammonia after eating Yucca but is it harming me in so way that makes it not worth my while. Then there's the issue of how much to take for benefit. I only take a quarter inch carrot slice worth of it with each meal but even that seems to be more than what would be in a 500mg pill. Anyway, if there's any Yucca, Quinoa or Saponin experts out there, would love to hear your views!!
