My current favorite brand for the base supplements has switched from Thorne to Momentous. Most (All the ones I take at least) of their supplements are audited/certified (which is not the case for Thorne) and they have one or both of the “NSF certified sport” and “Informed Sport Certified” certifications. Compared to Thorne some supplements are cheaper and some more expensive. The ones I take are a little bit cheaper.

How do we know they are not making it up? Supplement companies play dirty with each other all the time.

I did a search for Urolithin A after reading about it here on Rapamycin.news
I found a product from Saglikli that looked like a good price ($63) for 240 capsules.
But, every review reads like a marketing promo written by the same person with different account names. The accounts all had posted only one or two reviews and all for the three supplement products that Saglikly sells on Amazon. If you google Saglikli the have no web presence, no address, no phone, etc.
I reported them to Amazon early last week and the agent said they would report their findings to me in a few days. Haven’t heard back and product is still on their site.

“Sağlıklı” means “healthy” in Turkish. Probably a Turkish company then? I would avoid…

FWIW: The supplement field is ripe with fraud. It seems like we need to check the source of every single one of the supplements we take.
“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 the identification of Astaxanthin”
“14 out of 22 samples failed potency testing and 13 out of the 14 failures contained less than 1 mg of astaxanthin. Each of the 24 mg products failed very badly and the only gummy tested contained less than 1% of astaxanthin”
- contained less than 1% of astaxanthin.

If people would just follow good advice and buy from reputable companies that test every batch with 3rd party lab testing and then post the Certificate of Analysis (CoA) on their website, then quality and purity shouldn’t be a concern - and especially safe if you buy directly from the company’s website. As with many things, it’s caveat emptor so you should follow good practices. Aside from Bulk Supplements, Doublewood, Horbach and NOW, the names on that list are ones that I’ve never heard of.
