A heat-sensitive item is any product that may be modified by high temperatures or long-term heat exposure. Many different products can be considered heat-sensitive and the concern with exposure can be quite variable.
You'll be alerted of any heat-sensitive products in your order during checkout and recommend our Priority shipping option to reduce time in transit.

Probiotics lose colony forming units (CFUs) over time when exposed to elevated temperatures. However, probiotics range in temperature sensitivities in that some are shelf-stable and do not require refrigeration, while others require ice packs for shipping and refrigeration for storage.
Fish oils, flaxseed oils, and other oil-based products may be labeled heat-sensitive as a precaution to prevent spoilage. Proper storage becomes imperative after opening.
Some softgels that are exposed to high temperatures can become very soft and stick together, thereby making them heat-sensitive.
Storing heat-sensitive products at home
While the packaging for shipping is important for your heat-sensitive item, long-term storage is by far the most significant factor. A container may be stored in your home for months and this will play a major factor in the shelf life of heat-sensitive products.
The following are general guidelines that we suggest you follow:
- Follow the storage instructions on the bottle – not all heat-sensitive products will need refrigeration.
- Moisture leads to mold – leave cotton balls or silicon packets inside the bottle.
- Close the lids on all containers tightly.
- Avoid storage in the bathroom or near the stove in the kitchen.
