Update 3/9/20. Leptigen is a weight loss supplement that contains an interesting ingredient called MeraTrim. Does Leptigen work? Does It have any side effects? Who makes Leptigen? These will be some of the questions I'll try to answer in this review. Leptigen is not the same thing as Lipothin which is another weight loss supplement. See the DietSpotLight Burn review for more information.
What Does The Name Mean?
The name Leptigen is interesting because it reminds me of “Leptin” a hormone, made inside fat cells that play a role in hunger. The idea behind the name is a subtle reference that it might influence leptin levels and in doing, curb appetite and promote weight loss.
That said evidence the Lepigen alters leptin levels could not be located.
On the FAQ page of Leptigen.com it's stated that:
“we referenced 284 published scientific studies to verify the claims that we make about the ingredients in Leptigen.”
Understand that while research exists on the ingredients of the supplement, that is not the same thing as research on the supplement itself. To best understand the supplement its necessary to look at its ingredients.
Let's do that next.
Each capsule of Leptigen has these ingredients:
|Decaffeinated green tea extract||200 mg|
|Chromium polynicotinate (Chromate)||100 mcg (83% DV)|
The label lists these 2 ingredients as well:
- Green Select EGCG
See the Research Section below.
Leptigen also contains these “other ingredients”
- Silicon dioxide
- Magnesium stearate (vegetable source)
- Lecithin phospholipids
These other ingredients play no role in the effects or benefits of the supplement.
This is another name for chromium. It's a combination of chromium and niacin (a B vitamin). Supplements often contain chromium bonded to vitamins to increase absorption. Chromium has been used in weight loss supplements for many years, although most research shows it does not work. See the review of chromium and weight loss .
Chromium polynicotinate is sometimes found in weight loss supplements, likely due to a study from the 1990s noting that it helped women lose weight (woman taking chromium picolinate actually gained weight).
See the review of chromium polynicotinate for more information.
Leptigen uses a trademarked brand of chromium polynicotinate called “ChromeMate” made by a company called InterHealth Nutraceuticals (now part of Lonza company). To support its effects this study noted it helped people lose weight more than a placebo.
Leptigen contains 100 micrograms of ChromeMate which is more than the above study used, so that is good.
Many weight loss supplements contain caffeine. The idea is probably twofold:
1. caffeine appears to have a small fat burning effect
Leptigen has 75 mg of caffeine per capsule. That's about what is in a cup of coffee.
Green Select EGCG
This is a trademarked version of green tea found in Leptigen. This form is supposed to be better absorbed than “regular” green tea. Another name for this ingredient is Green Select Phytosome. One study showing Green Select Phytosome helped people lose weight.
- Sphaeranthus indicus
- Garcinia mangostana
There is some weight loss research on MeraTrim.
The research notes that Meratrim works when people take 800 mg per day. I'll assume Leptigen has this amount but I'm not sure as I could not determine the amount from the label.
See the MeraTrim Review

Previoulsy the BBB used to list another website for the company – “Avesil.com.” Before Leptigen, there was another weight loss supplement called Avesil. Their ingredients looked very much alike.

Does Leptigen Contain Soy?
Yes, the label indicates that the product contains soy. The soy may come from the Green Select EGCG extract which has a little bit of soy. Generally soy is not a problem for most people.
