Start living Life Again!

Super Flex Back Formula offers you a natural way to enjoy life to the fullest. This exclusive formula is really three formulas in one.

Three Formulas In One!

1. Natural back relief!

Super Flex Back Formula includes a special blend of ingredients that help inhibit the COX-2 enzyme.

2. Unique formula helps support connective tissue!

This unique blend of natural ingredients includes the remarkable MSM (methylsulfonylmethane). Studies suggest that MSM may help bind water in the cartilage matrix, keeping cartilage soft and spongy so it absorbs the pounding of movement and activity.

3. Special ingredients to help break the sore cycle!
Sore muscles contract. Super Flex Back Formula can help support healthy muscle relaxation.

Suggested Use

Take one tablet 3 times daily.

Other Ingredients

Cellulose and/or maltodextrin, calcium silicate, magnesium stearate and stearic acid.

The US FDA advises that a potential risk of rare but severe liver injury may be associated with kava-containing dietary supplements. Ask a health care professional before use if you have or have had liver problems, frequently use alcoholic beverages, or take any medication. Stop use and see doctor if you develop symptoms that may signal liver problems, including jaundice (yellowing of the skin or whites of the eyes) and brown urine. Other nonspecific symptoms can include nausea, vomiting, light-colored stools, unusual tiredness, weakness, stomach or abdominal pain and loss of appetite. Do not use if you have bile duct obstruction, gallstones, stomach ulcers or hyperacidity. Not for use by persons under 18 years of age, or by pregnant or breastfeeding women. Not for use with alcoholic beverages. Excessive use, or use with products that cause drowsiness, may impair your ability to operate a vehicle or heavy equipment.

Works great at relieving my back pain when I take it at the first sign of pain. I love how I can save money by purchasing it in multiples.
