Heat Stability - Probiotics, Oils & Tart Cherry

Updated by Meytal - HealthPost Team Member

We understand the importance of making sure the natural health and wellness products you recieve are in their best condition. We take extra care of products which may be impacted by heat or light.

Products that are best kept refrigerated remain chilled until packed and dispatched. We always keep our stock out of direct sunlight and away from direct heat sources.

We also have a range of shelf-stable probiotics available that don’t require refrigeration.

Manufacturer's guidelines for heat sensitive products:

Shelf-stable probiotics

Products should be kept below 25 degrees Celsius in dry conditions.

Probiotics that require refrigeration

Store in the fridge as much as possible. Manufacturers add overage (more probiotics than what is on the label) to account for some loss of potency during shipping. Overage allows for 1 – 2 weeks of the product at room temperature.


Store in the fridge once opened. Manufacturers flush bottles with inert gas to help prevent oxidation. Keep lid tightly closed once opened.

NZ customers:

All orders, whether they contain heat sensitive products or not, are dispatched on the first available courier, typically 1-2 working days after placing your order.

What if I order over the weekend?

Heat sensitive products are generally fine during weekend orders, but we always recommend placing your order for these sorts of items at the beginning of the week.

Will my local courier be notified about these products?

While we use ‘please keep cool’ stickers on all heat-sensitive parcels, we can’t guarantee that your courier driver will be aware of this. However, if you have a cool spot where you’d like the parcel left, please make sure you note this in the ‘Delivery Instructions’ field at checkout.

We also have many shelf-stable probiotics which don’t require refrigeration.

Australia and international customers:

All our orders are sent un-refrigerated.

We take no responsibility for orders containing products that aren’t stable at room temperature.

We also can’t accept the return of these items from international orders.

Thanks for choosing HealthPost - we're with you in wellness.
