This has always been a concern of mine...are your probiotics alive when you buy them? Or do they survive long on your counter? Must they be refrigerated? Karl Seddon of Elixa Probiotics explains...
Hello! This video answers one of the most frequent questions I get via email. Usually in the form of: 'Will the probiotics be OK in the delivery truck / mailbox / in my porch, (etc.) ?' It also answers the other question of whether they need to be stored in the fridge, freezer, or on a shelf. - Karl Seddon
I like Karl's videos, he consistently presents very informative content in an easy to follow syle. I subscribe to his youtube channel.
ReplyDeleteAlso I came across an interesting study on reddit - Fructooligosaccharide (FOS) and Galactooligosaccharide (GOS) Increase Bifidobacterium but Reduce Butyrate Producing Bacteria with Adverse Glycemic Metabolism in healthy young population

I guess there is an ideal balance point between supporting bifidobacterium versus supporting the butyrate producers.
Interesting paper. I'd be curious to see this repeated with RS supplements as RS is shown to increase bifido and butyrate producers. I think the biggest hurdle for all gut flora research is similar to what these researchers noted:
ReplyDelete"When comparing the results of OGTT, we found high interpersonal variability (Fig. 5A). The OGTT of nine subjects was elevated after FOS, but reduced after GOS (Blue dots in Fig. 5A). Whereas, six subjects had the opposite situation."
Gut flora is unique to the individual and highly variable.
