What is a heat-sensitive item?

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.

Probiotics, oil based supplements, and softgel products are a few examples of products that could be sensitive to elevated temperatures. However, exceptions within each category may also exist.

  • Probiotics – 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.
  • Oils – fish oils, flaxseed oils and other oil-based products may be labelled heat-sensitive as a precaution to prevent spoilage. Proper storage becomes imperative after opening.
  • Softgels – some softgels that are exposed to high temperatures can become very soft and stick together, thereby making them heat-sensitive.

During the checkout process, you will be notified which items are heat-sensitive on the shipping selection page. If you would like more information on a specific product and why it may be considered heat-sensitive, please contact [email protected]

Are all heat-sensitive items shipped with an ice pack?

Yes! The ice pack leaves our warehouse frozen, so while it thaws, it cools the insulated environment inside the box to temperatures well below the extreme heat that can cause damage. The ice pack is free of charge and will be included in every heat-sensitive shipment regardless of the shipping method selected.

Which shipping option do you recommend?

Priority shipping (maximum 3 business days) is widely accepted as the heat-sensitive shipping option, however, overnight shipping should be considered for those individuals that are especially concerned about the time the product is in transit.

Helpful Hint: Priority shipments placed on Monday or Tuesday will have less time in transit since the weekend (non-business days) will not be a factor.

How do I store heat-sensitive items?

While 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:

  1. Follow the storage instructions on the bottle – not all heat-sensitive products will need refrigeration
  2. Moisture leads to mould – leave cotton balls or silicon packets inside the bottle
  3. Close the lids on all containers tightly
  4. Avoid storage in the bathroom or near the stove in the kitchen
