Heat-sensitive product storage and shipping recommendations

A heat-sensitive item is any product that may be modified by high temperatures or long-term heat exposure. Fullscript takes steps to help protect heat-sensitive products during transit, and understanding how these products are handled — and how to store them after delivery — can help maintain their quality.

Common heat-sensitive product types

Heat-sensitive products include supplements that may be affected by prolonged exposure to warm temperatures. Common examples include:

• 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 labeled heat-sensitive as a precaution to prevent spoilage. Proper storage becomes imperative after opening.
• Softgels: Softgels may soften or stick together when exposed to heat. Storing them in a cool, dry location can help preserve their form and quality. Softgel products typically ship without ice packs, based on supplier guidance.

Heat-sensitive products are labeled on the product page and in your cart so you’re aware before placing an order.

Ordering heat-sensitive products

We recommend our priority delivery option for all heat-sensitive products to reduce time in transit. We also recommend placing orders earlier in the week when possible to reduce the chance of packages sitting in transit over the weekend.

Heat-sensitive products are labeled in checkout to help with delivery method selection.

How Fullscript packs heat-sensitive products

Fullscript uses special packing methods to help protect heat-sensitive products during transit. Depending on the product, destination, and weather conditions, this may include:

• Insulated packaging or insulated sections within the shipment
• Cold packs when appropriate
• Shipping heat-sensitive orders earlier in the week when possible

Cold packs are designed to slow temperature changes during transit. It’s normal for cold packs to arrive thawed, and this doesn’t necessarily mean the product was exposed to damaging temperatures.

Storing heat-sensitive products

While the packaging for shipping is important for your heat-sensitive item, long-term storage is by far the most significant factor. At our warehouse facilities, we adhere to rigorous supplement quality control standards that affect how we receive, store, and ship products.

You may keep a product at home or in your office for months. How you store that product will significantly impact its shelf life, especially in the case of heat-sensitive products.

The following are general guidelines that we suggest you follow:

• Bring packages inside as soon as possible after delivery.
• 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.
• Store supplements in a cool, dry place away from heat, humidity, and direct sunlight. Avoid storing supplements near windows, appliances, or in areas like kitchens or bathrooms.

Proper storage after delivery helps maintain product quality and potency.
