"Force Factor is the first product without any harmful ingredients and stimulants in the market place for healthy body builders. I highly recommend the product as it does not stimulate your nervous system and thus when you decide to stop taking Force Factor, you will experience no withdrawal syndrome."

Dr. Marko Baer - Nutrition Immunology, Oxford, United Kingdom
"The combination of Force Factor and my protein regime has been awesome. I've looked into the science behind nitric oxide supplements, and it's very real."
-Craig Jaynes
"I have noticed that even when doing light weight, my muscle fullness becomes larger. I can honestly say I have noticed my biceps being larger than they have ever been. I have also noticed more endurance while running-easier breathing."

"Arginine, also known as L-arginine, is involved in a number of different functions in the body. They include: wound healing, helping the kidneys remove waste products from the body, [and] maintaining immune and hormone function. As a natural dietary supplement, arginine has garnered particular attention for its possible heart benefits."

Formulated by Former Harvard University Rowers

As teammates on the Harvard Championship Crew team ('04-'06), the founders of Force Factor were looking for a healthy product that would increase both their endurance for long workouts and their strength for sprints. They tested lots of products. Some were loaded with caffeine and unnecessary additives. Others were just ineffective.

Unable to find the right product, they created Force Factor. The natural elements boosted their energy, endurance, and power. The encapsulated formula provided the perfect balance to their athletic lifestyles.
