To ensure the continued high quality of our products, Rexall Sundown follows rigorous testing procedures.

After selecting only the highest-grade ingredients available, we test them to ensure that they meet our strict requirements for quality, potency and purity. Then, we carefully monitor the formulation and manufacturing processes, testing before, during and after production. More than 12,000 tests per month are completed to ensure that quality goes into our product before the Rexall Sundown name goes on the bottle.

These extra measures have earned us the highest scores from one of the most prestigious independent quality audit firms in the health product manufacturing industry, and they've helped us earn the trust of consumers who rely on us for quality health products.
