All Natural Ingredients

The natural relaxant works by combining three ingredients that have been used for centuries for their supposed relaxing qualities. Since Formula 303 is homeopathic, the ingredients are not listed in milligrams. Formula 303 employs six parts valerian root, three parts passion flower, and one part magnesium. The perfect mix for an all natural muscle relaxant.

Valerian Root

Valerian is a flowering plant that is native to Europe and parts of Asia. The valerian plant has been used for centuries for its medicinal effects. Ancient Greeks used valerian root as a cure all. They believed that it could help with digestive ailments, urinary tract disorders, liver problems, nausea and insomnia. Hippocrates even used it as a sleep aid to combat insomnia. It has also been used to help nervousness. Today herbalists suggest taking valerian root for its presumed abilities to relieve pain and muscle spasms.


Some might know Passion Flower was first discovered in 1569 and has been traditionally used to calm anxiety. Some scientists believe passion flower may increase levels of gamma aminobutyric, also known as GABA, in the brain. GABA works to lower activity in the brain. Decreasing brain activity may make it is easier to take your mind off worries, leaving you feeling relaxed. Passion flower may promote sleep and relieve muscle cramps.*


Magnesium is one of the most important minerals you can consume on a daily basis. The benefits of magnesium are seemingly never ending, and in Formula 303, it complements the valerian root and passion flower. Magnesium may counteract stress, help stabilize nerve cells, and maintains nerve balance. Without magnesium, nerves would be in a constant state of stimulation. Magnesium may work to relax the nerve cells, and in turn possess a calming effect.

Formula 303 Testimonies

"Over the years I have sustained injuries that often cause pain. I do not like to take NSAIDS or other analgesic products because of their negative effects on the body. Formula 303 which was recommended by my chiropractor has been a God-send! I can go through most days pain-free thanks to this wonderful product!"

"I have problems with sciatica, so I sometimes use this product to help me rest better at night. It can also be used throughout the day (low dose) to help with muscle pain related to stress or overdoing. My entire family (teens, young adults, and middle aged folks) have used this product at one time or another over the years. This website has the best price I can find for Formula 303."

"Formula 303 is the only all-natural product I've tried that helps me sleep. I've tried several OTC products as well as prescription drugs. Formula 303 does not give you that "drugged" feeling. After about 30 minutes, you simply get a little more relaxed and you fall asleep more easily. I recommend you try it."

"My 31 year old daughter had suffered with anxiety and tried 303. So later on when I had gotten a job that was on the high stress level she shared 303 with me and I couldn't believe well it worked. Since then my wife and have told and given 303 to numerous people. We have never heard of anyone that was disappointed with the results."

"I have an old whiplash injury in my shoulder. I've tried many different remedies to relax it when it gets tight or achy, but Formula 303 works best. It's not quick; you have to take it regularly for a couple of days, but it gets the spasm and knots out without any side effects."

"I ordered Formula 303 for relief from a pinched nerve. Within the 1st day, the spasms were gone and the pain started subsiding. 5 days later, I'm fine. I highly recommend this product!"
