There has been some discussion and concern recently regarding proper probiotics storage. Having used and prescribed probiotics for a number of years, we feel it is important to clarify this issue.

It is generally known that probiotics should be stored in the refrigerator to minimise the lost of potency.

However, after dispensing thousands of bottles of probiotics at our clinic during the past three years, we have found that refrigerating probiotics in tropical weather like ours can be counter-productive.

We have had very many reports of probiotics powders hardening up within weeks of usage despite being stored in the refrigerator – or rather, because of being stored in the refrigerator.

Even probiotics in capsules are not spared. This is due to moisture condensation that occurs when the probiotics are taken in and out of the refrigerator.

We have found that the best practice in the tropics is to store probiotics in a cool environment.

An air-conditioned room is probably best but may not be feasible for some families. Otherwise, any cool place, away from sunlight or other sources of heat – such as cooking and electrical appliances – will do.

The crucial point is that probiotics should be dispensed in the same temperature environment that it is used to store them. This is to minimise moisture condensation that can result in spoilage.

Next, buy the highest bacteria count you can afford to ensure that at least many bacteria are still viable at the time of consumption.

Thirdly, buy the smallest bottle / quantity available.

Storage of probiotics in the tropics is one instant when it is wise not to blindly follow established practices.
