I recently started hearing a lot of buzz surrounding Force Factor, a dietary supplement that builds lean muscle quickly. The claims sounded good, so we decided to do an in-depth review of the ingredients, side effects, clinical research, and customer service. We even read through forum posts to see what people are saying. Finally, we condensed it all to give you the info you need.

Force Factor Readers: Click here to find out why we're giving away samples of our product, Pronabolin.

What is Force Factor?

Let’s jump right in: Force Factor’s headlining ingredient is “Advanced 3x Nitric Oxide Booster,” which is composed of A-AKG, A-KIC, and L Arginine Monohydrate. The “Advanced Nutrient Delivery System” rounds out the supplement, and it includes Calcium Phosphate and L-Citrulline. Each container comes with 30 servings, most of which are taken on workout days. When used as instructed, the formula helps to build lean muscle, promote endurance and maximize strength.

Force Factor is a Cambridge, MA-based product that came into existence in 2009. It was founded by two Harvard rowers. You can order online via the official website. We like the ease of use and the formula for nutrient delivery seems original and interesting, but read on…

A Free Trial – “Try Before You Buy”

First off, after looking through a series of online reviews, it looks like Force Factor uses its “Try It Now” option as a free trial. “Offering the customer the option of trying out a product before they have to pay full price is common in this market,” said our Research Editor. “But, this helpful option never grows old.”

“I received the small sample, and then decided to buy a month’s supply,” one user said.

Another said. “I ordered a test size sample of Force Factor for $4.99 to try as I am an athlete.”

“I must confess that I was skeptical when I bought it, but it proved…worth it,” said one user.

Another shared, “I’ve noticed an…uptick in my energy levels during and after my workouts.”

Customer Support – “Standing Behind the Company”

One of the best things to find when researching a company or product is strong customer support. “I have been using Force Factor for a while now, and I have noticed a real difference since I started using it,” one user said.

Another offered, “It really does give you an extra boost of strength its helped me out a lot.”

One more bit of support said, “One of the few supplements that I have found to work for me.”

We’ve noticed that even a small issue can hinder a supplement’s long-term success; users simply don’t want to put up even the littlest of things. With Force Factor, we found some good support and there’s even a free trial – good options.

What Does the Science Have to Say?

The NIH features many articles discussing the benefits of Nitric Oxide. The website claims that the supplement has been clinically studied. Without a doubt, the ingredients in the formula do support NO production. Here at DietSpotlight, it’s nice to see a product with claims that are actually supported by research.

The Bottom Line – Does Force Factor Work?

We’ve reviewed a lot of supplements and Force Factor initially had us interested with it’s approach to lean muscle building. It seems to avoid many cliche ingredients, and it’s easy to use. A free trial is available and customer support is strong. This is a good option for a pre-workout.

If you’re still in the market for a supplement that will promote lean muscle, there are options out there with clinically tested ingredients and strong support.

In addition to a strong pre-workout, you may want to think about adding a supplement shown to help enhance vitality and support muscle growth. Among the best products we’ve seen this year is one called Pronabolin. A supplement made from a proprietary blend of nine powerful ingredients. These have been shown, via clinical testing, to support testosterone production and we can’t find talk of harmful side effects online. Better yet, the online reviews look great.

For the time being, there are multiple-bottle discounts and a 120-day money-back guarantee: this is a company that stands by its product.

What You Should Know

Force Factor, a sport nutrition product invented by two Harvard competitive rowers. It includes amino acids as the basis of its technology. The supplement increases energy, endurance and aids in weight loss. This process is achieved through raising the amount of Nitric Oxide in an individual’s body.

List of Ingredients

Force Factor ingredients include 3x Nitric Oxide Booster, AKG, A AKIC and L Arginine, and L-citrulline. Three of the most active ingredients are Nitric Oxide, Arginine, and L-citrulline.

Product Features

Nitric Oxide, naturally found in your body, helps to communicate with all its different parts. By raising the amount in the body, exercisers may increase their bodies ability to communicate and therefore they may find their workouts more successful.

Arginine, not a naturally occurring substance within the human body, may help strengthen immunity, remove toxins from the body, regulate sodium levels, assimilate protein properly, and increase metabolism.

L-citrulline, an amino acid, supposedly shortens the recovery times after workouts, helps increase energy, removes ammonia from the body, and benefits the liver.


  • The product does not cause harmful side effects.
  • The ingredients help improve the success of a workout.
  • An official Force Factor website makes ordering the product easier.


  • We'd like to see some clinical links on the official website; but there's research into the ingredients.
