Natural Stacks has partnered with Intertek, the most respected ISO, ANS, and IEC accredited laboratory in the World, to ensure the potency and purity of every ingredient after each production. We don’t release products for sale unless they are absolutely perfect.
Potency: The third party lab tests show the exact amount of each and every ingredient. Due to the natural degradation in some ingredient over time, the potency of your product may be slightly lower than what appears on the lab test.
Purity: Standardized identity testing ensures the authenticity of the ingredients. This proves every ingredient is in it’s natural state has not been adulterated.
Below is an example lab test. On each product page you will see the most recent post-production third party identity lab test, proving that what’s on the label is exactly what’s in the product.
