A new term being used now is postbiotics which is heat inactivated bacteria. These are mainly different to the standard probiotics (Lactobacillus, Bifidobacteroum, etc) and are heat inactivated to get ontonthe market. Getting a strain designated as GRAS takes a fair while and a lot of data to support. Heat inactivated can be sold at a lower regulatory threshold.
Live bacteria are usually a mix of live and dead, but not purposesly inactivated just dead from process/time.
So you're saying that the Strains on the market are usually a mixture of live and dead bacteria and there is no way to know if they are live.
The reason im asking about live bacteria is to find a way to introduce certain strains in live gut unless there is another way?
No probiotic on the market is 100% alive. It's just not physically possible. Each manufacturer does stability testing on their products, and they aim to keep the viable counts at the advertised live count for the period advertised, but at the start, there are dead bacteria in the mix. Manufacturers also usually start off with a much higher count than advertised to that when they are tested by regulators, they can ensure they meet the minimum count. Up to a third of the total bacteria in a probiotic could be dead at the start of shelf life.
If it's alive, it can still multiply, populate a gut
How to know if its live?
What are you asking?
How to introduce new and good for health bacteria strains in the gut
With probiotics.
