Frequently Asked Questions
Imagine if your unexplained joint discomfort, tiredness, or headaches were all linked to a single overlooked factor. For years, hypermobility was seen as just added flexibility, but recent research has revealed a hidden genetic element affecting how the body processes a vital nutrient. What's even more surprising is that the solution might be as straightforward as taking a vitamin supplement.
Hypermobility goes beyond flexibility—it's frequently caused by a genetic variation impacting connective tissue, resulting in various physical and mental health issues.
Folate insufficiency plays a crucial role – A mutation in the MTHFR gene decreases the body's ability to process folate, weakening connective tissue and contributing to hypermobility.
A simple remedy exists – Supplementing with methylated folate (5-MTHF) has shown promising outcomes in easing symptoms, providing hope to millions globally.
Can you bend your elbow backward? How about touching your wrist with your thumb or placing your hands flat on the floor with your legs fully straightened?
If you're double-jointed, you can easily perform these unusual feats of flexibility.
For some individuals, however, double-jointedness can be the cause of a serious medical condition known as hypermobility, leading to various physical and mental symptoms.
Until recently, medical professionals were puzzled about how to address this surprisingly common condition. But now, there's a solution. And it's incredibly simple...
You don't need a doctor or any medication. All it entails is taking a unique over-the-counter version of the B vitamin, folic acid.
Hypermobility is estimated to impact one in every four people. Unlike double-jointedness, hypermobility is identified not only by increased flexibility but also by fragile connective tissue due to genetic mutations.
Since connective tissue offers support in skin, tendons, ligaments, blood vessels, internal organs, and bones, its fragility leads to a range of symptoms that seem unrelated on the surface: physical issues like joint pain, chronic fatigue, thin tooth enamel, dizziness, digestive problems, and migraines; and psychiatric disorders such as anxiety and depression.
Hypermobility mainly stems from Ehlers–Danlos syndrome (EDS), a group of thirteen connective-tissue disorders, with twelve linked to genetic mutations. However, 90 percent of cases arise from hypermobile EDS, the only subtype lacking a known genetic cause.
Consequently, the diverse symptoms have typically been treated individually rather than as a consequence of a single underlying cause. But now, researchers at Tulane University School of Medicine in New Orleans have identified a root cause of hypermobility.
The research team has connected hypermobility to a deficiency of folate – the natural form of vitamin B9/folic acid – caused by a mutation of the MTHFR gene.
All individuals have two MTHFR genes, one inherited from each parent. A mutation can occur in one or both of the most common gene variants. Approximately 20 percent to 40 percent of white and Hispanic individuals in the U.S. have one mutation. In North America, Europe, and Australia, around 8% to 20% of the population have mutations in both genes.
This diminishes the activity of the MTHFR enzyme by about a third in those with one mutation and by two-thirds in those with both mutations. What are the implications of this?
Reduced enzyme function hampers folate metabolism, preventing key proteins from binding collagen to the extracellular matrix that provides structural support for the body. This leads to more elastic connective tissue, hypermobility, and a potential chain of related conditions.
Surprisingly, hypermobility affects as much as 57 percent of the population. The reason it's not widely acknowledged is that most individuals with the condition won't encounter any issues, and some, like ballet dancers, gymnasts, and musicians, benefit from it. Yet for others, the condition can be disabling.
The link between folate deficiency and the MTHFR gene was uncovered through interactions with patients at Tulane's Hypermobility and Ehlers-Danlos Clinic, the sole clinic in the U.S. focusing on connective tissue disorders.
Its director, Dr. Jacques Courseault, remarked: “Hypermobility is not rare, it's widespread and unfortunately under-recognized. Hypermobility is akin to a luxury car that demands a lot of maintenance and the finest synthetic oil. After knowing a patient's name and date of birth, I believe it's wise for clinicians to discern which of these body types they possess.
“I'm enthusiastic about being able to help the masses where individuals aren't spending their entire lives feeling frustrated and not receiving the necessary treatment they require."
The treatment he refers to is very straightforward...
Since folate is poorly metabolized in these patients, they are provided with methylated folate or 5-MTHF, the form it assumes after being acted upon by the MTHFR enzyme.
Dr. Courseault mentioned that patients treated with methylated folate have exhibited improvements: less pain, reduced brain fog, fewer allergies, and enhanced gastrointestinal function.
“We've unearthed a medical intervention that can aid, not a small group of individuals, but potentially many worldwide. This is real, it's been thoroughly vetted, and clinically, we're observing a positive change.”
I couldn't agree more.
If you're pondering whether you might be among the millions with an MTHFR gene mutation, a simple blood test can provide the answer. And if you're experiencing pain or other ailments, I urge you to obtain one without delay. You could be one of countless individuals suffering physical issues simply because they can't properly absorb folate.
If you do have an MTHFR gene mutation, methylated folate supplements are economical and readily available online and in health food stores.
Hypermobility, often mistaken for harmless flexibility, can be an indicator of a more severe condition linked to a genetic mutation in the MTHFR gene. This mutation diminishes the body's ability to metabolize folate, weakening connective tissues and leading to joint pain, fatigue, migraines, and even psychiatric symptoms like anxiety and depression. Researchers at Tulane University have now pinpointed a simple yet effective remedy: supplementing with methylated folate (5-MTHF). With potentially millions affected, this breakthrough presents renewed hope for those grappling with unexplained health troubles.
Hypermobility denotes excessive joint flexibility due to weak connective tissues, often linked to genetic factors, whereas being double-jointed simply means having naturally flexible joints without associated health concerns.
This mutation hampers the body's ability to metabolize folate, resulting in weakened connective tissues and a variety of physical and mental health symptoms.
Symptoms encompass joint pain, chronic fatigue, migraines, dizziness, digestive problems, thin tooth enamel, anxiety, and depression.
A simple blood test can ascertain whether you carry this genetic mutation and whether you could benefit from methylated folate supplements.
Methylated folate (5-MTHF) is widely accessible over-the-counter in health food stores and online. It is generally safe, but consult with a healthcare provider before commencing any new supplement regimen.
