You mention in the original post that amazon ships the listed probiotics: MegaFlora 50-14, Flora 50-14 from Innate Response, Flora 200-14 from Innate Response, and Renew Life Ultimate Flora. Do you believe shipping from amazon is wise if a cold pack is not provided? Will the probiotics maintain their beneficial qualities throughout a 3 to 5-day journey?
Also, I plan on drinking lots of kefir. Is it possible to eliminate expensive probiotics at a certain point and continue to consume my homemade kefir milk as my only probiotic? I live in a hot and desolate area–an inconvenience if I must ask for 1-day shipping to keep my products cool.
