Nutritional Supplements and Hot weather

We have been experiencing surges in daily temperatures, with this reaching 38.1 degrees centigrade in parts of the UK and highs of between 40 and 43 degrees centigrade in areas of Europe. With predicted rising land temperatures this is something we will be experiencing more often. However, has anyone noticed how this can affect their nutritional supplements? Let’s take a look at some key points for consideration.

Time to recheck storage conditions.

Typically, supplements may be purchased and stored in the ‘usual’ cupboard. However, with daily temperatures rising increasingly rising beyond 28 degrees centigrade, the usual cupboard may no longer be sufficient. In the Summer months recheck the storage conditions of your supplements and consider relocating these.

Find a suitable supplement home.

In general, avoid leaving supplements close to warm or humid environments. Storing these near to windows, below skylights, near to ovens, kettles, on top of the refrigerator, close to sinks or in bathroom cabinets can expose them to humid and warmer surroundings.

Always check the label regarding storage instructions. For those that don’t need to be kept in the fridge, the bedroom can provide a good stable temperature. If the kitchen is preferred a cool, dark cupboard or pantry can also be suitable.

*It can be worth rechecking the temperature of food cupboards (with a manual thermometer or mobile app) during periods of extreme heat.

Store away from light.

When exposed to excessive light and heat the vitamins present in supplements may degrade faster. Supplements may also warm and start to clump together. For these reasons avoid leaving supplements out on the kitchen counter, or table when daily temperatures begin the heat up. Closing kitchen and bedroom blinds may also help to minimize light entry and keep the temperature down.

Pay particular attention to probiotics.

Probiotics are living organisms so just like us, they will thrive and function better when kept in a suitable environment. Look for probiotics that are stored in a dark-coloured glass container which can help to protect from light damage.

Always read the label carefully – some probiotics may need to be refrigerated. For those that are “shelf-stable” a cool, dry cupboard should be suitable, but monitor these during extreme hot weather conditions.
