Flexcerin uses the tried-and-true glucosamine-chondroitin formula then adds a few novel anti-arthritis remedies. How effective is this formula? Read on to find out.

What is Flexcerin?

Flexcerin Maximum Bone and Joint Support Formula is an all-natural oral medication for providing relief from joint pain and inflammation caused by age, arthritis and injuries.

This over-the-counter formulation is manufactured by Vitaloix Labs. It is presented as easy-to-swallow tablets. Flexcerin is meant to treat a broad spectrum of arthritis cases from those involving mild pain to severe pain.

Each of the ingredients of Flexcerin has been clinically proven to support joint health and treat arthritis pain. Because these ingredients are obtained from natural sources, they do produce very little side effects compared to conventional arthritis drugs. They are also safe for long-term use.

Flexcerin Works By...
  • Reducing pain and inflammation
  • Rebuilding joints by promoting the regeneration of damaged and lost cartilages
  • Maintaining joint health and slowing the progression of arthritis in elderly patients
  • Protecting endorphins and encephalins which are endogenous painkillers naturally produced in the body
  • Blocking pain signals
  • Stimulating increased production of synovial fluids
  • Protecting chondrocytes from harmful enzymes and free radicals
  • Providing the nutritional supplements and precursors needed for rebuilding the cartilage and increasing the viscosity of the synovial fluid
  • Improving blood supply and the distribution of nutrients to the cells of the cartilage

The Ingredients of Flexcerin

Glucosamine Sulfate

Glucosamine sulfate is an amino sugar which is naturally found in bones and marrows. It is one of the building blocks of a class of structural molecules called glycosaminoglycans.

The most popular source of glucosamine is shellfish and it is also the source from which the glucosamine in Flexcerin is obtained. Therefore, people with shellfish allergy may show allergic reactions to this product.

Glucosamine sulfate is the rated as the most effective form of glucosamine because the sulfate group improves the distribution and the effect of the glucosamine in the body.

Glucosamine slows down the degeneration of the cartilage. It also promotes the repair of the cartilage and other connective tissues holding bones together at the joint. This is possible since it is the precursor of glycosaminoglycans which are the building blocks of the cartilages at joints.

Lastly, the glucosamine supplied in Flexcerin will improve the lubricating quality of the synovial fluid and trigger the production of new glucosamine molecules in bones.

Glucosamine is commonly combined with chondroitin and MSM.

Chondroitin Sulfate

Chondroitin sulfate is a group of glycosaminoglycans called aggrecans. Therefore, unlike glucosamine, it does not need to be converted into some other compound before it can be used by the body.

Chondroitin sulfate is produced in the cartilage and its most important sources are the cartilages of cows and sharks.

Each chondroitin molecule is made up of 2 alternative monosaccharides: D-glucuronic acid and N-acetyl-D-galactosamine. A chondroitin molecule may be made with any number of these monosaccharides. Some chondroitin molecules have over 100 of these sugar molecules in their structure.

Each monosaccharide on the chain of chondroitin may carry none, one or two sulfate groups. These sulfate groups gives the molecule an overall negative charge which is important to its function.

Chondroitin sulfate chains aggregate to form a mass of extracellular matrix that gives cartilage its structure. They are responsible for the cushioning effect of the cartilage and also its ability to flex and return to its original position without allowing the bones at the joints to wear against each other.

However, when the cartilage is damaged either due to injury or age, new chondroitin sulfate needs to be taken to replenish the ones at the joint. Therefore, the chondroitin in Flexcerin can slow down the progression of arthritis symptoms and even reverse the damage done to the cartilage by rebuilding it.

Chondroitin sulfate is a safe dietary supplement and like glucosamine sulfate, it only produces minor gastrointestinal side effects.

Hyaluronic acid

Hyaluronic acid is also a glycosaminoglycan like chondroitin sulfate. However, it carries no sulfate groups and it is not an aggrecan.

Hyaluronic acid has two main functions at the joints: it promotes the lubricating properties of the synovial fluid and it contributes to the linking aggrecans together.

Because if its importance, there is a high turnover of hyaluronic acid in the body. A third of the body’s store is used up daily. Therefore, there is a need to keep producing the compound. However, injury and age can lead to a slowdown in the synthesis of hyaluronic acid.

When this happens, hyaluronic acid must be supplied to the body just as it is when Flexcerin is taken.

Hyaluronic acid increases the viscosity of the synovial fluid. It is one of the 2 lubricants that is found in this fluid, and its major role is to allow bones and other structures in joints to slide smoothly over one another.

Hyaluronic acid also protects the cells of the cartilage from by broken down by enzymes and free radicals. It forms a protective coat around them.

Lastly, hyaluronic acid is needed for holding other glycosaminoglycans together by linking them to special molecules to form the connective tissues of the joint.

Methylsulfonylmethane or MSM

MSM is an organosulfur compound that is needed for joint support. It serves as a sulfur source which makes up the sulfide link holding the building blocks of proteins such as collagen together.

MSM is therefore responsible for the strength of cartilages. By supplying the sulfur needed to hold amino acids together, it ensures that tensile strength of proteins made out these amino acids is preserved.

MSM also has other functions too. It is known to change the permeability of cells of the cartilage. This allows the cells to take in more nutrients to speed up the repair needed to regenerate cartilages.


Rutin is a bioflavonoid glycoside obtained from citrus fruits, berries, buckwheat and asparagus.

Rutin possesses anti-inflammatory and antioxidant properties. Therefore, it can protect the synovial membrane and cartilage from the damage caused by harmful free radicals. It is also effective for reducing joint swelling and the pain accompanying it.

Lastly, rutin increases blood flow by thinning the blood. Therefore, care should be taken when Flexcerin is combined with anticoagulants.


Bromelain refers to a group of protein-digesting enzymes obtained from the stem of pineapples.

Its culinary use is as a meat tenderizer but it has always been used in traditional medicine to control swelling. Today, Bromelain is used for its ability to address both acute and chronic inflammation.

The anti-inflammatory action of Bromelain involves its ability to inhibit the production of proinflammatory chemokines as well as prostaglandin. It also prevents the mobilization of neutrophils to the sites of injury.


Trypsin is a proteolytic enzyme naturally produced in humans.

Its chief function is to break down proteins. Therefore, trypsin can be useful for dissolving clots and opening up blood circulations to inflamed joints.


Lecithin is a class of related fatty acid and phospholipid compounds obtained from different sources.

The lecithin included in Flexcerin is obtained from soy.

Two popular phospholipids found in lecithin are phosphatidyl choline and phosphatidyl inositol. These are found incorporated into cell membranes. Therefore, they can help strengthen synovial membrane and prevent the kind of damage that could lead to the leakage of synovial fluid.

Boswellia serrata Extract

The extract of Boswellia serrata is obtained from the resinous exudate of the boswellia tree.

The major active ingredients of this extract are boswellic acids. Different clinical studies have demonstrated the efficacy of boswellia extract in reducing joint pain and inflammation.

The 3 mechanisms by which boswellia extract produce its anti-inflammatory effects are by

  • Inhibiting the release of the proinflammatory leukotriene, LTB4
  • Preventing the mobilization of neutrophils to the site of injury
  • Stabilizing mast cells and preventing their degranulation


Boron is an ultratrace and essential mineral. While its importance to plant development was long recognized, its usefulness in human metabolism and growth are only just understood.

Boron deficiency is closely linked to and highly correlated with arthritis.

Boron improves bone health by regulating the parathyroid hormones. It also increases the production of vitamin D and estrogen by activating their precursors. Boron also prevents the excretion of calcium and magnesium which are needed for the re-mineralization of bones.

In addition, boron also protects the synovial membrane from autoimmune damage and harmful free radicals.

Lastly, boron promotes the entry of adenosine triphosphate (ATP) into the cells of the cartilage where they provide the energy needed to drive tissue repair and the regeneration of connective tissues.

Does Flexcerin Work?

The recommended dose of Flexcerin is 2 tablets taken in the morning and 2 tablets at night.

Flexcerin is an effective product for relieving joint pain and it acts quickly too even though it also includes active ingredients such as chondroitin and glucosamine which provide long-term support for joints.

Flexcerin includes all of the known and effective natural joint pain remedies and it also a few that are not usually found in arthritis medications.

Boron is one example of the little-known but multi-functional and clinically proven arthritis remedies included in Flexcerin.

Furthermore, Flexcerin is an affordable medication to more expensive conventional arthritis medications and some natural remedies from big brands.

A good number of Flexcerin users are satisfied elderly arthritis patients who agree that the medication is effective for relieving joint pain, reducing swelling and improving the range of activities they can safely undertake.

With high praises from reviews and glowing testimonials from its users, Flexcerin is a highly rated and effective joint support formulation. Most users report the first signs of benefits within the first week of use and the manufacturer backs the product with the industry-standard 30-day money-back guarantee.

Even though Flexcerin has fewer reports of gastrointestinal side effects usually seen with products including glucosamine and chondroitin sulfate, it may still cause hypersensitivity reactions in people with shellfish allergy.

Other people can however take advantage of the immediate pain relief and the long-term joint support provided by Flexcerine.
