Heat Sensitive Products
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 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.
If a product you are ordering is heat sensitive, we will display a notice on the Shipping Method selection step, during checkout, recommending the Priority shipping option.
Shipping Heat Sensitive Products
Heat sensitive products will be shipped with an ice pack that leaves our warehouse frozen. 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.
We strive to prevent exposure to extreme heat or long periods outside of the recommended storage determined by the manufacturer. Because of this, we recommend priority shipping to reduce the amount of time that your product will be in transit. Be sure to place your order before the order cutoff time, 3pm EST Monday-Friday, to ensure your order is processed and shipped same day. Alternatively, you can consider placing your order over the weekend, after 3pm EST Friday, for your order to be packed and shipped the following Monday.
Packing Your Heat Sensitive Order
Products shipped from our warehouse will have specific packing rules depending on the sensitivity of the product being shipped. This may include being shipped in an insulated bag or being sectioned off from the other products in the package to stay in close vicinity of any cold packs added to the shipment.
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.
