Why is my capsule/powder a different color or consistency?

United Naturals /Nature M.D. tries to use the highest quality ingredients it can. We also avoid artificial coloring. As such, the color and consistency our capsule could change, sometimes significantly, from batch to batch. Rest assured that all our supplements are manufactured in facilities that are cGMP-compliant and routinely inspected by the FDA. cGMP stands for Current Good Manufacturing Practices, and it is a rule established by the FDA to ensure that manufactured supplements are free from contamination, and are therefore safe for our customers. We are committed to offering only the highest quality and most effective supplements, which is why we choose only the best U.S. manufacturers and take the extra step of independently testing our supplements to ensure the ingredients match the label. Our policy is to strictly adhere to the most rigorous standards in the industry.

As such, your product is not only safe to take, it is highly effective and lives up to the United Naturals/Nature M.D. quality guarantee.
