It was suggested that I try getting on a good probiotic to help with my GI issues- Good meant, liquid form and high concentration. However, a trip to the store where the only option I could find that was liquid and dairy free was $50 for a 30 day supply revealed that this is outside of my budget. Someone suggested naturally fermented kefir. That got me looking at the tangent of naturally fermented foods. I've done lactofermented pickles before and it's not hard. Many of the recipes used whey though, to help start fermentation. That isn't really an option for me but I did find a source that indicated that water kefir and water kefir grains can be used instead. It might be interesting to try.
