Could heat during delivery reduce the effectiveness of my Better D3 + K2?Updated a day ago

Thank you for asking, and we want to put your mind at ease!

Vitamin D3 and K2 are more resilient than most people expect. They hold their potency at room temperature for years, and D3 only begins to break down at cooking-level heat far beyond anything a package experiences in transit. Also, our softgels seal the nutrients away from the air, light, and moisture that are the real factors in long-term degradation.

Paired with our FDA-approved, BPA-free PET bottles, your D3 + K2 is well protected through standard shipping, even in summer. Once it arrives, a cool, dry cabinet is all it needs to stay at full strength.
