Pros & Cons
Pros
- Two ingredients, no stimulants
- Label doses published (on NuviaLab)
Cons
- No human weight-loss trial of barley grass
- Forskolin at 10% of the trial dose
Who Is This For?
Recommended For:
We would not recommend it for weight loss. Neither ingredient has good evidence at these doses.
Not Recommended For:
Pregnant or breastfeeding women and children (the label's own exclusion), people with coeliac disease unless the seller confirms it is gluten-free, and anyone expecting rapid weight loss.
Summary
What is in it, per 2 capsules: green barley grass extract 1,000 mg and Coleus forskohlii extract 50 mg (about 5 mg forskolin). No caffeine, green tea or other stimulants.
What the evidence says:
- We found no human weight-loss trial of barley grass, only a study in rats.
- Forskolin trials used 50 mg a day, ten times this dose. In men it reduced body fat; in women it did not produce weight loss.
- The claims contradict each other: the US page promises "24 lb in 2 months"; the Swiss page says up to 12 kg in 12 months, above a chart showing 12 kg at week 8.
Refunds: 10 days from purchase, for unused goods.
Ingredient Breakdown
The label on the retailer NuviaLab's store lists two active ingredients per 2 capsules: green barley grass extract (Hordeum vulgare) 1,000 mg and Coleus forskohlii root extract [10% forskolin] 50 mg, in a plant-based capsule with acacia fibre. The sales pages show no amounts.
What the research shows:
- Barley grass. Our PubMed searches found no human trial of barley grass or young barley leaf for weight loss. The only anti-obesity study was in rats fed a high-fat diet. The one human trial we found gave 15 g a day of young barley leaf extract to 36 people with type 2 diabetes for 4 weeks and measured cholesterol oxidation, not weight. Barley grain and its beta-glucan fibre are a different material.
- Forskolin. Thirty overweight men took 250 mg of a 10% forskolin extract twice a day (50 mg forskolin) for 12 weeks; body fat fell compared with placebo. In 23 mildly overweight women, the same dose "does not appear to promote weight loss".
Correction. An earlier version of this review described Green Barley Plus as a caffeine and green tea fat burner, warned about stimulants and a "green taste", and cited green tea, Garcinia and CLA studies. It is a capsule with two ingredients and no stimulants, and we have corrected it. Our green tea extract guide covers the ingredient it does not contain.
What Green Barley Plus does not tell you
Two ingredients named, green barley and coleus forskohlii, with no amount for either.
Amounts are taken from the manufacturer’s own supplement facts panel. Where a label states a standardisation, the active fraction is what we compare, because the active is what the trials measured.
Dosage Analysis
Our Dose Check compares the label with the human studies.
- Barley grass extract: 1,000 mg vs no human weight-loss study. The only human trial used 15 g a day and did not measure weight.
- Forskolin: about 5 mg vs 50 mg a day for 12 weeks. 10% of the trial dose.
The directions are 2 capsules a day, about 30 minutes before a meal, with 300 ml of water. A bottle of 60 lasts a month.
Quality & Testing
Our Transparency Score checks five things a buyer can verify. Green Barley Plus scores 2 out of 5.
- Label with doses: yes, but only on NuviaLab. The Swiss page our link leads to shows no amounts.
- Identifiable company: no. The Swiss site names Key Player Limited, Dubai Airport Freezone; the English site names only "GreenBarleyPlus.com" in Hong Kong. The label says "Country of origin: European Union". No manufacturer.
- Refund terms in writing: yes. 10 calendar days from purchase, unused goods only.
- Independent testing shown: no.
- Study on the finished product: no. The weight-loss chart has no source, and the testimonials (one claims 53 kg lost) use first names only.
The sales page also says barley grass "removes toxins, including heavy metals" and that the product "does not cause any side effects".
Correction. An earlier version of this review claimed GMP manufacture, a $55 price, free shipping and a 90-day guarantee. The page our link leads to makes no guarantee, shipping is charged, and we have corrected it.
Value for Money
Prices when we checked in September 2026:
- Swiss site (where our link leads, in German): CHF 49.99 for 1 bottle, CHF 99.98 for 3, CHF 149.97 for 6, plus CHF 9 shipping by card.
- German site: €49.99, plus €6. US and NuviaLab: $49.99 (US shipping $12). UK: £44.99, plus £14.
The return rule. The terms allow withdrawal only "within 10 calendar days from the date of purchase", in writing, for goods with no signs of use, and state that EU law does not apply. The German page adds an open-ended money-back promise; the Swiss page makes none.
Side Effects & Safety
- Forskolin: the two 12-week trials above reported their results as body composition and hormones; check with your doctor or pharmacist if you take regular medication.
- Barley grass comes from barley, a gluten grain; the label does not say whether it is gluten-free.
There is no clinical study on Green Barley Plus itself.
Final Verdict
Our Verdict
Green Barley Plus is simpler than most fat burners and has no stimulants. But barley grass has no human weight-loss trials, forskolin is at a tenth of the studied dose, and the brand's own pages cannot agree whether you will lose 12 kg in 8 weeks or in 12 months. Returns are limited to 10 days for unopened bottles. We do not recommend it.
