L-Carnitine Texture Change

Regarding your L-Carnitine that has become wet or creamy even though it's not expired, this is likely due to the product absorbing moisture from the air.

L-Carnitine is known to be very hygroscopic, meaning it easily attracts and holds water molecules from the surrounding environment. The product description specifically advises keeping the lid tightly closed and avoiding moisture because it is very prone to absorbing humidity.

While the expiration date indicates the general shelf life under proper storage conditions, the change in texture suggests that it has been exposed to significant moisture. Although it might not be harmful to use, the quality, stability, and intended properties of the L-Carnitine may be compromised once it has absorbed moisture and changed from its original powder or flake form.

Therefore, it is generally recommended to avoid using L-Carnitine that has become wet or creamy due to moisture absorption, even if it is not expired, to ensure optimal results.
