NSP vs. The Competition – Product Comparison


More Testing Means A Better Product

Quality means giving you exactly what you want-and nothing else. Our raw materials and finished products undergo more tests than other companies’.

Herbal Fingerprints


Nature’s Sunshine uses Thin Layer Chromatography (TLC) to positively identify each lot of plant material that is used in our products. Think of it as taking the plant’s “fingerprint.” Every herb species has a unique TLC print, so we use this test to verify that we have the correct herb species, the correct part of the plant, and the correct natural actives in the plant.

We often combine TLC testing and High Performance Liquid Chromatography (HPLC). We compare the “fingerprint” and analytical test data of the new lot to a known standard to be sure we have the correct herb and to ensure that key components are present in the correct ratios. For example, golden seal is an expensive herb used to support the immune system. Barberry herb has a similar appearance and chemical composition, but it costs just a fraction of what golden seal does. Some vendors may be tempted to dilute their golden seal with barberry to save money. But NSP scientists can detect this kind of adulteration and reject any tainted lots of material.
