Current formulas, evidence limits, availability, and caffeine caveats
How we review + disclose: We compare current product pages, label transparency, stated stimulant load, availability, and official health guidance before linking out. Some outbound links are affiliate links. This guide is informational and not medical advice.
People compare non-stimulant products to avoid adding a large caffeine dose, especially when coffee, pre-workout, or evening training is already part of the day. “Stim-free” describes the stimulant position of a formula; it does not prove weight-loss efficacy, zero side effects, or zero naturally occurring caffeine.
We rechecked official product pages on August 23, 2026 and compared their labels with NIH weight-loss supplement guidance. NIH says there is little scientific evidence that weight-loss supplements work and describes the average weight effects of CLA and carnitine as small.
Not sure whether you are actually a stim-free case? Use the Stim Fit Checker before buying. It adds current caffeine load, pre-workout use, sleep, training time, and medical red flags instead of assuming caffeine-free is the answer for everyone.
What we verify before calling a product “stim-free”: the current manufacturer's stimulant claim, whether green tea is identified as decaffeinated, ingredient amounts, availability, and whether the label has changed. People with strong caffeine sensitivity should still inspect the bottle for residual or naturally occurring caffeine.
| Product | Caffeine | Key Ingredients | Servings | Best For |
|---|---|---|---|---|
| EVL LeanMode | 0mg | CLA, Garcinia, L-Carnitine, Green Tea | 50 | Best value |
| Transparent Labs Stim-Free | 0mg | Forskolin, EGCG, Capsimax | 60 | Current test links |
| 1st Phorm L-Carnitine | 0mg | Powder formula; verify current label | See label | Current format check |
| Legion Phoenix Stim-Free | 0mg | Green Coffee, Irvingia, Green Tea, 5-HTP | See label | Reformulated formula |
| Jacked Factory Lean XT | 0mg | ALCAR, Green Tea, Coleus | 30 | Four-ingredient comparison |
| NutraKey CLA 1250 | 0mg | CLA 1250mg (80% active) | 90 | Sold out when checked |
The current EVL LeanMode page lists five active ingredients and identifies the product as stimulant-free. The disclosed amounts make comparison possible, but the label does not establish meaningful weight-loss results.
NIH says CLA and carnitine might produce only a small average weight effect and that garcinia cambogia has little to no effect. Although the green tea extract is labeled decaffeinated, people with strong caffeine sensitivity should still inspect the current bottle.
The current Body Recomp Stim-Free page lists no added caffeine and links manufacturer testing documents. It is not the same formula as the stimulant version, and the official page showed it as sold out when checked on August 23, 2026.
The label lists 300mg of green tea extract standardized to 50% EGCG, which equals 150mg EGCG, plus 250mg ForsLean. NIH says the weight effect of green tea is small and the evidence for forskolin is insufficient. “Stim-free” should not be read as proof that green tea extract contains absolutely no residual caffeine.
1st Phorm's current official L-Carnitine product is a powder, not the liquid formula previously described here. The page directs users to mix one scoop and use it twice daily; check the current Supplement Facts image for exact amounts before comparing it with older listings.
NIH says carnitine might help people lose only a small amount of weight. Because the format changed, this page does not carry the old liquid amounts forward to the current powder.
The current official Phoenix Stim-Free page shows a substantially different 3-capsule formula from the older version that was previously listed here. The current page links research citations, but citations for ingredients do not prove that the finished product causes meaningful weight loss.
The current ingredients include green coffee, Irvingia, green tea, grains of paradise, and 5-HTP. NIH says there is not enough reliable evidence for meaningful weight loss from many common supplement ingredients, while 5-HTP can interact with medications; inspect the complete warnings before considering this formula.
Lean-XT is a four-ingredient stimulant-free formula from Jacked Factory. The current official label lists higher ALCAR and green tea amounts than the older formula previously shown on this page and adds a Coleus extract.
NIH says carnitine's average weight effect is small, green tea's effect is small, and forskolin did not affect body weight in a small trial. The manufacturer markets the formula as stimulant-free; inspect the current green tea label if trace caffeine is a concern.
NutraKey's official CLA 1250 page remained live but showed the product as sold out when checked on August 23, 2026. The listing is retained to explain the label and availability, not as an in-stock recommendation.
The official listing describes 1250mg of CLA per softgel standardized to 80% active isomers. NIH says CLA might help people lose only a very small amount of weight and body fat; this page does not turn research amounts into a dosing recommendation.
These ingredients are common on stim-free labels, but a biological role or marketing mechanism is not the same as evidence of meaningful weight loss.
“Non-stimulant” usually means no added caffeine or stimulant blend. Some formulas still contain green tea extract, which can have residual naturally occurring caffeine unless the label says it is decaffeinated. Read the current Supplement Facts panel.
CLA is a fatty acid found naturally in meat and dairy. NIH says it might help people lose only a very small amount of weight and body fat and can cause digestive side effects.
Carnitine has a biological role in energy production, but NIH says weight-loss studies show only a small average effect.
NIH says green tea might help with a small amount of weight loss. Concentrated extracts can cause side effects and have been linked to liver damage in some people.
Forskolin comes from Coleus forskohlii. NIH says it has not been studied much for weight loss and did not affect body weight in a small trial.
Garcinia cambogia contains hydroxycitric acid. NIH says it has little to no effect on weight loss.
Capsicum extracts are marketed for thermogenesis. NIH says there is not enough research to know whether capsicum helps people lose weight.
Glucomannan is a soluble fiber marketed for fullness. NIH says it has little to no effect on weight loss and can cause gastrointestinal side effects.
A stim-free label may be worth comparing for:
People training later may prefer not to add caffeine close to bedtime. Check for naturally occurring caffeine and follow the current timing directions.
People vary in caffeine sensitivity. A product with no added caffeine can reduce stimulant load, but the rest of the label still matters.
A no-added-caffeine formula avoids adding another large stimulant dose. Combining supplements can still create ingredient overlap or interactions, so compare both labels.
Caffeine tolerance can build. Reducing stimulant intake is a separate decision from whether a non-stimulant weight-loss product is useful.
No product should be assumed appropriate indefinitely. Follow the label and review long-term use with a qualified clinician when medications or health conditions are involved.
The clearest benefit of these labels is avoiding a large added caffeine dose—not proven fat loss. EVL LeanMode provides a current multi-ingredient label; Transparent Labs Body Recomp Stim-Free links current testing but was sold out when checked; 1st Phorm now sells a powder rather than the old liquid format.
Use official product pages to verify the current bottle and availability, and use NIH guidance to keep the limited evidence in view.
