At Ara Testing Labs, we get a lot of questions about blended supplement products and testing requirements. Many manufacturers are told they don’t need to test blends because of recovery issues. In some cases, labs struggle with how to approach these products at all.

From a Food and Drug Administration (FDA) compliance standpoint, our position is clear and simple: you should test the blend to understand how the ingredients interact.

Every product is unique, and the best way to know your product is through testing, to build your product’s FDA compliance story. Once you have data, you can see what’s happening in the formula.

For example, we’ve seen enzyme and probiotic blends perform well and meet label claims. However, we have also seen situations where certain ingredients show unusually high or low recovery.

Your label is the visual representation of what’s inside the bottle. Sometimes probiotics start to break down in the presence of enzymes, while others remain unaffected. Building your product’s FDA compliance story will help protect you.
