Forslean Review - Does This Supplement Work? Are side effects and ineffectiveness deal breakers?

Editor's Review: 2.5 / 5.0
Forslean Review

97% of all dieters are looking for a product that just works. Yeah, we’re not really sure about the other 3%, either. We took a long look at Forslean, checking on the ingredients, side effects, clinical research and customer service. Hundreds of reviews and experiences were taken to heart. Then, we condensed and refined to give you the bottom line.

EDITOR'S TIP: Substitute Forslean with a proven fat burner such as Leptigen for better results.

What You Need to Know

First off, Forslean is a branded version of coleus forskohlii. There may be other ingredients in the product you choose, so check the label. You typically take the supplement once or twice daily, but again these directions will vary. The bottle is relatively small, so it’s portable.

Forslean is manufactured by Sabinsa Corporation. The company claims to have a patented formula for promoting lean body mass and weight management. You can buy the product online and in some stores. We like that it is gaining popularity in the weight-loss market, but read on…

Side Effects – “Any Concerns?”

The first thing that concerned is was the potential for Forslean side effects. According to our Research Editor, “If there is the potential for negative reactions that may be more than enough to convince the dieter to skip a supplement.”

“Never could use it enough days for my purpose to take effect! After a few days of use diarrhea developed,” said one user.

Another claimed, “Lately at night feeling a little more munchy hungry.”

Scroll below for one of the best products we’ve seen over the last year.

Ineffectiveness – “Really?”

In addition to reports of side effects, we also found problems with effectiveness in Forslean ingredients. “I see no results of any kind. Perhaps this product just isn’t meant for me,” was one experience.

Another said, “I took this product faithfully for 45 days and saw no change in my weight.”

We have to add that there were some users who saw mild results. One offered, “This one worked for me and I have not had any side effects.”

The Science – “Any Real Proof?”

You can find a ton of products on the market that contain Forslean. Each supplement will have different results, but if you’re looking at just this, there’s little proof it works better than ones with multiple, clinically proven ingredients. At DietSpotlight, science tells us whether or not to give the green light and this time we just can’t.

The Bottom Line – Does Forslean Work?

Should we race out to buy up some Forslean? Well, we like that there is some research into coleus forskohlii and the price is affordable, in most cases, but we are hesitant to give the thumb up because there are much better formulas out there that’re clinically proven to work in humans. We also worry that some products may cause side effects, if only because of additional ingredients.

If you want to get things started and lose more weight, we suggest going with a supplement that’s made with 100% scientifically proven ingredients that’s both affordable and free of reported side effects.

Among the best products we’ve seen in 2016 is one called Leptigen. The formula contains four proven ingredients, with well known weight-loss properties. We have performed extensive research on this formula and are especially happy with the lack of negative reviews that surfaced. It’s also amazing the number of users who’ve reported great results.

The makers of Leptigen have such confidence in the formula that they’re offering a Special Trial Offer. That’s a nice touch!

Forslean is a weight loss supplement that is manufactured by Sabinsa Corporation. Sabinsa Corporation says that it is a patented Phytonutrient for weight management that promotes lean body mass. The main active ingredient in Forslean is the root extract of Coleus Forskohlii. Coleus Forskohlii is an ancient ayurvedic plant that is a member of the mint and lavender family. It grows in the mountains in Asia and is becoming an increasingly popular ingredient in many natural weight loss products.


The main ingredient in Forslean is the patented root extract of the Coleus Forskohlii plant.

Product Features

There is a very detailed website available for Forslean. The website contains a number of scientific papers detailing research carried out on the weight loss properties of Coleus Forskohlii in Japan, the USA and India. These trials do show a modest weight loss benefit that can be linked to the use of Coleus Forskohlii. The active ingredient in Coleus Forskohlii is Forskolin. Forskolin apparently initiates a chemical process in the body that results in a burning of energy and fat cells.

Forskolin also increases thyroid activity, which in turn increases the rate of your metabolism and hence results in fat burning. Forslean can be ordered on line at a price of $15.99 for one hundred and twenty tablets. The manufacturers of Forslean say that you should take two capsules per day, as well as exercising three times a week and also follow a sensible diet while using this supplement. They also advise that you should not take Forslean if you are breast feeding, have low blood pressure or are taking any kind of anti asthmatic medication. It seems that Forslean has a lowering effect on blood pressure and also increases the amount of acid in the body, which means that it should also not be taken by anyone who has a stomach ulcer.

  • There is an official website for Forslean.
  • The official website contains a number of scientific papers detailing the results of clinical trials regarding Coleus Forskholii, the main active ingredient in Forslean.
  • There are contact details on the website for any customer service enquiries or complaints regarding Forslean.


  • There is no concrete evidence that Coleus Forskohlii is entirely safe for long-term use.
  • There is no clinical proof available to show how Forslean actually does procure weight loss.
  • You cannot take Forslean if you have low blood pressure, or are taking anti asthmatic medication.
  • The return policies for users unhappy with Forslean are not clear.


At the end of the day although the manufacturers of Forslean present a number of scientific papers on the web site regarding the active ingredient in Forslean, they do not present any evidence that it is superior to other weight loss products on the market. There are also a number of cautions associated with Forslean, and it does have a documented effect on a user's blood pressure. We would therefore recommend that you seek the advice of your physician before taking this weight loss product.

Does Forslean work?

There are two studies mentioned on the Sabinsa website (this is the company that makes Forslean.) Both were conducted by the company. That means they are not acceptable as proof as the business has a financial stake in the results. We did find a study on coleus forskohlii that showed no significant changes in body composition.

You may want to switch out Forslean for a product that does come with clinical support, like Leptigen.

Sabinsa does not sell the product directly to customers. You have to find a supplement that contains the ingredient. That means the price will vary dramatically.

    it’s hard to rate a product you never received, I have called this company 3 times and have been guaranteed this product would be delivered by a certain date, well that has never happened 4 weeks after I purchased this product & have been promised that I would receive it. Unfortunately I still have not received it. My husband & I both have called numerous times for a full refund, have been promised once again that tbe product would be delivered, still no product. They offered me a 30% refund & a $100 voucher. Really why would I want a $100 voucher with a company that has not delivered me anything! Do not order this product, this is a scam! I called & requested a full refund & have been hung up on 3 times. They still refuse to give me a refund, do not order from this company.

    I have not lost one pound. I have followed a proper diet and been exercising. I would not recommend this to anyone and for some strange reason it has caused me to gain weight.


    Ken Harlson

    From the research I’ve read this product causes a reduction in fat mass while increasing lean muscle mass. This will actually cause a slight increase in weight.
