Time of manufacture guarantees

Optibac supplements guarantee the billions count not just at the time of manufacture, but until the date of expiry.

The delicate nature of bacteria dictates that their quantity, in any given product or brand, will inevitably drop during the course of a shelf life.

Many live culture products have what is known as a 'time of manufacture guarantee'. This guarantees the numbers of friendly bacteria present at the time of manufacture. It does not necessarily guarantee the numbers of friendly bacteria at the time of purchase. 

Optibac are guaranteed until shelf life expiry. Our products understate the quantity of microorganisms they contain to allow for any drop in numbers. With Optibac, you get billions you can count on.
