|This product is advertised in pharmacies, using large posters, claiming to be effective in effective weight loss – without dieting or exercise being required! It is also advertised on the product’s local and international website.Any product that claims to result in weight-loss without having to control your diet is likely a scam.|
Conclusion after examining the evidence for this product’s claims:
There is zip proof that this product as a whole, or that the individual ingredients can with absolute certainty result in weight loss. It appears to be very likely another scam.
It also contains heartleaf – a source of ephedrine – a banned and dangerous ingredient.
And why is the product called Leptin Green Coffee when there is no green coffee in the product?
Stay away from this product!
Proof / Evidence for the product’s claims
The product claims:

The best part of this product is :

Green coffee 800 is a “drug-free” dietary supplement that was developed from a blend of herbal extracts. When used with a healthy diet plan, Green coffee 800 helps curb your appetite and also helps stimulating the body to burn fat and calories. Chromium dinicotinate glycinate plays an important role in the production of insulin, controlling hunger and in metabolism. Ginseng helps to maintain energy levels while dieting. Green tea leaf extract is a major antioxidant that increases mental awareness and helps diminish appetite and can also reduce the amount of harmful cholesterol.
The ingredients are claimed to be:
- 70 mg calcium
- 250 mg chromium ( as chromium dinicotinate Glycinate)
- 700 mg Propietary Herbal Blend: Green tea leaf standardized extract (180 mg antioxidant polyphenols,90 mg epigallocatechin gallate (EGCG), 50 mg naturally occurring caffeine, Asian Panax Ginseng root standardized.)
Although not listed in the ingredients list, on the website the product claims to contain extra: The herbal extracts and minerals used in this product were gathered around the world to make this diet supplement natural. Green coffee 800 contains anti-oxidant qualities necessary to cause thermo genesis that increases metabolism of fat. Chromium and Vanadium increase the burning of carbohydrates and metabolic rate. Panax Ginseng helps maintain energy levels while dieting. Another ingredient, Heartleaf, starts the process of burning fat while maintaining your appetite.
There are a number of sources of information to check for proof for the claims for the product or its ingredients. The two most well-known are:
- Natural Medicines Comprehensive Database (NMCD) “Unbiased, Scientific Clinical Information on Complementary, Alternative, and Integrative Therapies”. This database, a collection of reviews of ingredients is a major source of information for “complementary medicine / alternative medicine”, and is often used by health professionals working in this field. (http://naturaldatabase.therapeuticresearch.com/)
- PubMed “PubMed comprises more than 23 million citations for biomedical literature from MEDLINE, life science journals, and online books. Citations may include links to full-text content from PubMed Central and publisher web sites”. PubMed is a valuable source of information for “mainstream/orthodox” health professionals; however PubMed has also started including information from alternative medicine publications. (http://www.ncbi.nlm.nih.gov/pubmed)
These are among the sources of information we use to evaluate the claims for this product.
A. Evidence for efficacy for the whole product
There is not a single peer-reviewed published study throughout the world evaluating this combination of ingredients. There is no study demonstrating efficacy for a combination of some of these ingredients. This combination is novel.
B. Evidence for efficacy for the individual ingredients.
Here we already have a problem – the “proprietary herbal blend” does not tell you exactly what is in the product, probably deliberately. Does it suggest that of the 700 mg, besides those listed, the remaining 380 mg is Asian Panax ginseng? Or are there other ingredients hidden in the product?
1. Calcium 70 mg
There is no evidence that calcium is effective in weight loss
2. Chromium dinicotinate Glycinate 250 mg
Chromium dinicotinate glycinate, or CDG, is a form of the mineral chromium. Once inside your body, CDG breaks down into three distinct components, chromium, niacin, and glycine. According to the Office of Dietary Supplements, the Institute of Medicine has not established a tolerable upper intake level, or UL, for chromium because there is not enough evidence related to its effects in high doses. There is no information at all on this ingredient in NMCD! There is one article published in PMC that links liver toxicity to someone using a product containing this ingredient at a dose of 150 mcg (this product uses 250 mcg). There appears to be almost no evidence for the use of this ingredient in humans, but advertised as effective for weight loss! However, this ingredient may also be known as Chromium nicotinate glycinate or Chromium nicotinate.
The basic essential element this ingredient delivers is chromium (and various other forms of chromium are often claimed to assist in weight loss, e.g., chromium picolinate. As pointed out in the post on Herbex Appetite Control, there is simply insufficient evidence to support the claims for this ingredient.
NMCD states for Chromium:
INSUFFICIENT RELIABLE EVIDENCE to RATE:
Obesity. There is conflicting evidence about the effect of chromium on weight loss and obesity. Some clinical research shows that taking chromium picolinate orally might produce modest weight loss of about 1.1 kg compared to placebo when taken over 72-90 days (11962). But other research has found no benefit (6860,13727,17224). Two clinical studies show that taking chromium picolinate 400 mcg/day for 12 weeks does not significantly affect body composition, resting metabolic rate, plasma glucose, serum insulin, or serum lipids in overweight military personnel or obese women (6860,13727). Another preliminary clinical study shows that overweight adults taking 1000 mcg/day do not have significantly reduced body mass index (BMI) or central adiposity compared to placebo after 24 weeks (17224).
3 Green tea leaf standardized extract
The product states Green tea leaf standardized extract (180 mg antioxidant polyphenols,90 mg epigallocatechin gallate (EGCG), 50 mg naturally occurring caffeine). Green tea contains all these ingredients. Does this mean the product only contains green tea leaf extract or additional ingredients? Probably the former. However the evidence for green tea extract in weight-loss is that it does not work. Read more about the lack of proof for green tea in weight-loss.
4. Asian Panax Ginseng root standardized
This ingredient is not used for weight-loss. Its claimed use is for, among other, as a so-called “adaptogen” for increasing resistance to environmental stress and as a general tonic for improving well-being as well as loss of appetite.
There is no evidence for vanadium in burning calories or assisting in weight loss.
6. Heartleaf (also known as Country Mallow)
NMCD states for this ingredient: “There is insufficient reliable information available about the effectiveness of country mallow” and “LIKELY UNSAFE …when used orally. Country mallow contains the constituent ephedrine, similar to the herb ephedra. Ephedra, country mallow, and other ephedrine-containing herbs are banned in the US due to several case reports that have linked ephedra to serious side effects including hypertension, myocardial infarction (MI), seizure, stroke, psychosis, and others (1276,2729,6486,6998,9167,10689). Tell patients to avoid this and other products that contain ephedrine.”
There is zip proof that this product as a whole, or that the individual ingredients with absolute certainty can result in weight loss. Very likely another scam. And why is the product called Leptin Green Coffee when there is no green coffee in the product?
