Registry check · CLA
Does anyone independently verify CLA supplements?
We could not confirm a single one of these 5 products in any registry, and none of them claims otherwise. Not one brand here displays a certification mark, so on independent verification all 5 start level.
5 checked against all 5,317 US NSF, USP and Informed Sport listings, 2026-08-25. Full method and limitations.
What 5 CLA labels show
Priced per day, these CLA products run $0.17 to $0.58 — a 3.4× gap between the cheapest and dearest CLA here, across 5 brands.
Which row that favours is not obvious: BulkSupplements.com BulkSupplements.com CLA Softgels 1000mg is cheapest per serving at $0.17, but its serving sits below the median here, so part of that price gap is simply a smaller capsule.

The evidence · CLA
What the published reviews of CLA concluded
- Effect of Conjugated Linoleic Acid Supplementation on Serum Leptin Concentration: A Systematic Review and Meta-Analysis. · Endocrine, metabolic & immune disorders drug targets, 2018
“CLA supplementation might be able to decrease circulating leptin levels in studies with duration of less than 8 weeks especially among male and overweight subjects.”
- Effect of conjugated linoleic acid on blood inflammatory markers: a systematic review and meta-analysis on randomized controlled trials. · European journal of clinical nutrition, 2018
“This meta-analysis showed that CLA supplementation may increase inflammatory markers (CRP and TNF-α). There are concerns about using CLA supplementation as an anti-obesity agent among the obese population for at least a short duration.”
- Effects of conjugated linoleic acid and exercise on body composition and obesity: a systematic review and meta-analysis. · Nutrition reviews, 2023
“CLA combined with exercise is generally safe and can lower body fat and insulin resistance but does not reduce body weight, enhance exercise performance, or improve lipid profiles.”
- The effect of conjugated linoleic acid supplementation on oxidative stress markers: A systematic review and meta-analysis of randomized controlled trials. · Clinical nutrition ESPEN, 2022
“It seems this supplement can be used as a dietary supplement to improve oxidative stress parameters. However, further studies are required to demonstrate present results.”
Method: PubMed searched in humans for systematic reviews and meta-analyses with CLA in the title; these 4 of the 9 that qualified are shown with the authors’ own conclusion quoted rather than summarised. What it cannot tell you: whether CLA will work for you — each of these reports an average across trials published 2018–2023, and null findings are shown here as readily as positive ones.
How these 5 CLA products were ranked
Not one of these 5 CLA products could be confirmed in the NSF, USP or Informed Sport registries, so verification separates none of them and the ranking falls to cost per day at the labelled serving. Commission does not enter it: the rate is the same whichever CLA you buy. Full methodology.
