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.
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'.
Nature's Sunshine was the first company to encapsulate herbs, back in 1972. Our
commitment to offering only the finest-quality supplements has never wavered. We're
still adamant about offering only the best products to our customers worldwide.
Because we manufacture our own products, we can build quality into them and control
every aspect of testing along the production process.

NSP Essential Oils vs. the Competition
Comprehensive testing reveals discrepancy in quality
The label of a well-known competitor also indicated the use of two different
species of lavender, something you’ll never find in NSP’s pure, AOC-certified* lavender
oil. When two different species are mixed, you never know exactly what you’re getting.
NSP only uses true lavender, Lavendula angustifolia (no hybrids), in its product.
