I was in this industry and we used to tell people be careful what you buy. Many of the products at your mainstream stores would not have what they claimed on the label. Major brands at those stores even. Nowadays you can get better brands through Amazon, vitamin online retailers etc. But the problem still becomes you get what you pay for. Meaning a lot of the really cheap stuff isn’t what it claims to be.
A lot of us take supplements, and you really don’t want to bother taking something that doesn’t actually contain what you think.
I have to commend NOW Brand. NOW has decided to randomly test products. Sure it’s in self interest. They have to compete against the cheap stuff. But it also helps the whole industry to get rid of the non legit products because they won’t work and customers lose faith when that happens. They have been testing various companies and letting the public know. They mostly test companies sold on Amazon because a lot of these companies only sell there and that is suspect in itself.
So here’s the latest round. Astaxanthin. 13 of 22 brands tested had less than 1 mg in them when the claims were they had anywhere from 10 to 24 mg.

"NOW purchased two bottles of each product from 22 brands (including its own) on both Amazon.com and Walmart.com. It was obvious even before testing that many brands were mislabeling potency claims on the front label panel vs. the side panel. Two tests were performed to assess the quality of each brand: HPTLC and HPLC. HPTLC (high-performance thin-layer chromatography), was used for identification of astaxanthin as coming from Haematococcus pluvialis algae. HPLC (high-performance liquid chromatography) was used to quantify the amount of astaxanthin in tested products. NOW in-house labs tested astaxanthin by both techniques.
Externally, NOW sent one unopened bottle of each brand to Alkemist Labs to provide an independent report on the same products. HPTLC was performed by both NOW’s in-house lab and Alkemist Labs, an industry-leading botanical identification contract laboratory for identification of Astaxanthin.
According to NOW, brands were selected based on a number of qualifiers, such as being prominently featured on Amazon and Walmart’s online retail platforms and nowhere else. The company also tested lesser-known brands which have previously failed other testing rounds by NOW. For instance, aSquared brand failed seven different product tests and has the worst record for potencies tested among all brands. We Like Vitamins is another brand which failed six different tests, and each of this brand’s potencies were less than 33% of label claim.
About one third of brands tested were first-timers in NOW’s testing program. These included TerraVita, a brand which made a drastic label error by claiming that its dry capsules contained 450 mg of “astaxanthin algae.” Another product from We Like Vitamins had “Max Strength 10mg” but deceptively placed “10% potency yield” on the label of the product.
“NOW does this testing to publicly report which brandsare labeling accurately,” said Dan Richard, VP of global sales and marketing at NOW. “We welcome brands to communicate with NOW about these findings and openly share this information with all customers, industry trade groups, and FDA.”
