Do you ship with ice packs?
We do not.
To study the effects heat has on our products, we placed a bottle of Theralac in a temperature controlled environment at 100 degrees Fahrenheit for 96 hours. It did not lose potency. In fact, Theralac lost only 13% of it's total potency after spending 14 consecutive days at 100 degrees.
It is important to note that probiotics do not go bad or spoil like a carton of milk would in high temperatures. Our Totally Inert Packaging, which includes amber glass bottles, anti-oxygen and anti-moisture desiccant packets, a nitrogen flush, triple seal, and rayon wadding provides optimum stability and freshness.
Additionally, to counteract any potential loss of viability from improper storage, we blend our probiotics with vast overage in bacterial counts to guarantee that we can deliver the full listed potency throughout the entire two-year shelf life. We have been posting online, third-party lab test results verifying potency online since 2003 and you can check the official bacterial count for your lot here.
With 15 years of third party testing and experience shipping worldwide, we 100% guarantee potency through expiration when our products are shipped without an ice pack.
