Formula 303 Maximum Strength Natural Muscle Relaxant by DC Labs

An All Natural Supplement

Formula 303 uses natural ingredients to help fight muscle spasm and alleviate pain.* It contains valerian root, passion flower, and magnesium. Formula 303 may also help to calm the mind.

Formula 303 is a non-habit forming, homeopathic support for relaxing muscles and tension. This natural muscle relaxer can be appreciated by anybody. Doctors who have recommended Formula 303 to their patients have found that it was 80-85% effective.

Formula 303 provides natural relief of discomfort associated with:

• Leg Cramps
• Back Spasms
• Tension
• Muscle Spasms
• Nervousness
• Pulled Muscles

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!"

"This product really helps with muscle tension, muscle pulls and tightness in back and neck without making me sleepy at all. I have used it for years after being recommended by my chiropractor. i always have a bottle at hand and have given it to many friends who also use it now."

"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."

This is the best price I have found and they shipped it Lockett split I highly recommend both the product and Earth Turns."

"I first discovered formula 303 through my chiropractor - I've tried a few other, similar products when I've run out of this and wanted to try something new but nothing works like this does. It's well worth the money!"

"Formula 303 has been a life-saver for me. Trying not to use prescription drugs for my insomnia, I have discovered Formula 303 helps me sleep--gently. Mornings, I never have the grogginess from Rx. EarthTurns has a great product and price, AND sends it quickly."

"I have used Formula 303 for many years and have found good overall pain relief and muscle relaxation in my neck, shoulders, and back. Without it I couldn't get through a day from the pain from prior injuries. Friends have told me the same thing."

"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!"

"I have used formula 303 for years, it really relieves muscle tension, I can take a few of these before bed and my back ache will be gone by morning, it really loosens up things before I go to the Chiropractor too, it's almost a chiropractor in a bottle!!!"

    Smells Awful and doesn't seem to do near as much as any other relaxant I've used

    Published by HiItsMe on Jan 29th 2022

    It smells so bad that you don't want to be near the bottle, much less open it. It also seems to have no effect on me, whereas Relax Already and SwissRX Muscle Relax have proven to be very effective. It has all the boxes marked against it: bad smell, hard to swallow, ineffective. The only plus is that its cheap. You get what you pay for.

    Formula 303 WORKS!

    Published by Kaye on Mar 31st 2020

    I do not use drugs for pain. Have been taking Formula 303 periodically since Dec 2012 along with ibuprofen and aspirin., after chiropractor suggested it as a muscle relaxant for pain from old sports injury. Not only has it helped to relieve the pain, and relax knotted up muscles, I also found it helpful for chronic insomnia and it calms you on days when you have busy mind syndrome. It smells bad, but IT WORKS for me.
