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.

ForsLean Readers: Click here to find out why we're giving away samples of our product, Dietspotlight Burn.

What is ForsLean?

First off, ForsLean ingredient is coleus forskohlii. [1] 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…

ForsLean 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.[2]

Another claimed, “Lately at night feeling a little more munchy hungry.” [3]

Ingredient Blend – “Effective?”

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. [4] [5]

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 this year is one called Dietspotlight Burn. The formula contains four proven ingredients, with well known weight-loss properties. Users even report great results.

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

ForsLean: What You Should Know

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.

ForsLean 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.

ForsLean Advantages

  • 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.

ForsLean Disadvantages

  • 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.

Did you know it originates from Asian medicine? Their patented formula is suggested to help weight loss.

We took a good look at the Forslean ingredients to give you the crucial details you need.

Coleus Forskohlii

Coleus forskohlii is a plant that is often used in Ayurvedic medicine. It’s sometimes used to treat obesity, low testosterone levels, inflammation, allergies, bladder infections and irritable bowel syndrome. It’s found in a number of diet supplements, and is typically called forskolin. [1]

What is it Supposed to Do?

Generally coleus forskohlii is said to boost cAMP (cyclic adenosine monophosphate) levels, which in turn improves fat loss. It may also help widen blood vessels, which improves blood flow.

Clinical Research

“A study that appeared in the August 2005 issue of Obesity Research found that forskolin was beneficial compared with a placebo for overweight and obese men. Individuals taking the herbal component experienced a significant decrease in both body fat and fat mass, with a trend toward a significant increase in lean body mass.”

Clinical studies are an important part of the equation when it comes to selecting the right diet supplement. It’s wise to take a look at a product like Dietspotlight Burn. This unique formula contains ingredients that are backed by solid science.


Cellulose is a polysaccharide substance that is taken from plants. It’s commonly used to manufacture pharmaceuticals and dietary supplements, as well as various other products.

What is it Supposed to Do?

The purpose of cellulose is to help form the capsule or shell of supplements and pharmaceuticals. It encases or houses the key/active ingredients until the stomach dissolves the capsule or casing.

Clinical Research

There is no clinical research that ties cellulose to weight-loss. However, there are some studies that have shown the effectiveness of this ingredient for pharmaceutical and supplement manufacturing.

Magnesium Stearate

This is a chemical compound that is often used as an anti-adherent. It’s commonly used in the manufacturing of capsules, powders and tablets.

What is it Supposed to Do?

Typically magnesium stearate is used to make pharmaceuticals and dietary supplements. It functions as a type of lubricant, and prevents other ingredients from sticking or clinging to manufacturing equipment. [2]

Clinical Research

We could not find any documented research that links magnesium stearate to fat loss or weight reduction. However, this substance has been proven to be useful when manufacturing capsules, tablets and powders for the dietary supplement and pharmaceutical industries.

Is There Anything Out There That We Think TRULY Works?

Yes, we did find a supplement that fits the bill. Dietspotlight Burn, which is formulated with clinically tested ingredients, may be a good option to consider. Each and every customer can take advantage of a Special Trial Offer, that’s currently available. Click here to give it a shot.

ForsLean Side Effects:

According to most user experiences, Forslean is safe to use. However, there are a handful of potential side effects to be aware of.

Stomach Pain

Some users of Forslean claim to have experienced stomach pain upon use. Stomach pain consists of a “tightening” sensation in your abdomen. In more severe cases, it turns into a sharp piercing. Often, stomach pain is linked to the following symptoms: gas, bloating, fever, and sweating.

What causes stomach pain?

There are many causes of stomach pain. You may have eaten something that didn’t agree with you, either due to food intolerance or food allergy. You may have indigestion or pelvic inflammatory disease. It’s also possible that you contracted a stomach virus, bacteria, or parasite


Nausea is often referred to as feeling “sick” or “queasy.” It’s a sensation of having to vomit (although the nausea may go away without vomiting). Normally, nausea occurs simultaneously with stomach pain.

What causes nausea?

You can become nauseous simply by being exposed to something distasteful. Bad tastes, smells, an sights can provoke nausea even when you’re otherwise healthy. Nausea can also be sign of illness. Gallbladder disease, ulcers, and even some forms of cancer contribute to nausea. [1]


Diarrhea isn’t fun. It makes your stomach hurt, drains your body of liquid and nutrients, and sores up your rectum. Moreover, the constant bathroom trips make it hard to go about your day. It’s typical for a case of diarrhea to include bloating, gas, and stomach aches.

What causes diarrhea?

One of the prime culprits behind diarrhea is irritable bowel syndrome. Other digestive disorders may be responsible for your watery stool. Diarrhea also occurs when your stomach is infected with a virus or bacteria.


Headaches are very problematic. The pressure in your head can become overwhelming, especially with migraine headaches. When the pain gets really intense, you may even feel dizzy or light-headed.

What causes headaches?

Condition that might cause headache are ear infection, concussion, and high blood pressure. Brain aneurysm and stroke are also possible causes. [2] Most everyday headaches go away on their own. They’re caused by insufficient sleep, skipping meals, or being out in the hot sun for too long. Forslean is generally a safe product. However, keep in mind that everyone responds uniquely to weight-loss supplements. Talk with your doctor if you’re concerned about how the ingredients in Forslean can affect your health. Let us know about any additional side effects in our review section.

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.

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.
