Why has my WP-thyroid been discolored?

Since WP Thyroid is uncoated and formulated with minimal pure ingredients, the tablets can change color by absorbing ambient humidity.

However, exposed tablets outside of proper storage conditions still conform to USP specifications for both T4 and T3 potency and stability.
