How do I know if my supplements are safe?

We know that when choosing nutritional supplements, the quality of the ingredients and manufacturing is just as important as how well the product works.

At Jigsaw Health we make sure that all of our products are manufactured to the highest quality to ensure what's on the label is what's in the bottle, and nothing else.

We use Industry Standard Good Manufacturing Practices (GMPs) to ensure our products have the appropriate purity and potency.

We literally triple check our products before we release them to our customers.

  1. When raw materials are received, we test them for identity, purity, and potency.
  2. After the product has been blended and assembled into its final state, we test again for purity and potency.
  3. Lastly, when we receive the product to our warehouse in Arizona, it sits in quarantine until an independent third-party lab can verify the results of the first two tests.

When we receive the test results from the independent third party, we post them on our website for everyone to see.

We do all of this extensive testing because nothing is more important to us than the safety of our families and yours.
