“This is real, it’s been vetted out well and clinically we’re noticing a difference,”

Jacques Courseault, MD – Tulane University

The What and Why of Ehlers-Danlos

Did you ever meet a kid in the schoolyard that could twist themselves into weird positions? We called it “being double-jointed”, but this incredible flexibility can come from a condition you might not have heard of before– Hypermobile Ehlers-Danlos Syndrome, or hEDS for short. This is a complex condition that primarily affects the body’s connective tissue – the “glue” that helps hold our bodies together. From unusually flexible joints to delicate skin, people living with hEDS experience a wide range of symptoms that can impact their day-to-day lives.

Hypermobile Ehlers-Danlos Syndrome (hEDS) presents a range of health challenges that can significantly impact an individual’s daily life. Fatigue is a common issue, with sufferers often feeling perpetually drained, impacting their ability to carry out routine tasks. Pain, especially in the joints, is another major symptom, varying from occasional discomfort to constant agony. hEDS patients may also experience Postural Orthostatic Tachycardia Syndrome (POTS), a condition marked by rapid heartbeat and dizziness upon standing up, making even simple movements a challenge. Joint subluxation, where the joints partially dislocate, adds to the host of difficulties, causing discomfort and reducing mobility.

Diagnosing and managing hEDS is not an easy task. Because symptoms include so many different organ systems and such vague complaints, physicians unfamiliar with hEDS often mistake these patients for attention seekers and send them to psychiatrists. Tests are all normal. Unlike other conditions, hEDS doesn’t come with a handy lab test or genetic marker that doctors can use to confirm a diagnosis. This means that many people with hEDS face years of misdiagnoses before they finally get answers. To say this is a challenge would be an understatement. These patients often give up and stop being open with their physicians because of their long histories of not being believed.

The Breakthrough Discovery: Unusual Folate Levels and the MTHFR Connection

On the frontlines of understanding Ehlers-Danlos, a team of dedicated scientists at Tulane University has just published their exciting discovery. After treating numerous hEDS patients at their clinic, they started noticing a peculiar trend: these patients all had unusually high levels of folic acid in their blood.

When they looked deeper, they found that these high folate levels were consistently coupled with mutations in a gene known as MTHFR. In a nutshell, MTHFR is a gene that provides instructions for making an enzyme that helps our bodies process folate, a B vitamin, into its active form.

The connection between high folate levels and mutations in the MTHFR gene in Ehlers-Danlos patients was an eye-opening revelation. The team then connected the fact that animal model studies suggest that 5-methylTHF is necessary to deactivate an enzyme called MMP-2. MMP-2 (matrix metalloproteinases 2) breaks down a molecule named decorin — the “glue” that binds the scaffold that secures cells in place. So, the fragmentation of decorin by MMP-2 causes connective tissue to be loosely bound.

The Proposed Solution: Methylated Folate Supplements

The Tulane researchers’ breakthrough findings point towards an intriguing possibility for managing hEDS symptoms: a supplement containing 5-methyltetrahydrofolate, or 5-methylTHF. This is a form of folate that’s ready for the body to use without the need for the MTHFR enzyme to convert it first. [PMC10122021]

It’s an innocuous treatment. It’s not dangerous, and it’s a vitamin that can improve people’s lives. That’s the biggest thing: We know what’s going on here, and we can treat it.

Dr. Bix

You might be wondering, “Why not just eat more foods high in folate?” It’s a reasonable question. The folate that we typically get from our diet needs to be converted by our bodies into 5-Methyltetrahydrofolate 5-MTHF before it can be used. This process is precisely what’s disrupted in hEDS patients due to the MTHFR gene mutation. Therefore, eating more folate-rich food wouldn’t necessarily lead to higher levels of 5-methylTHF. In fact, it could lead to even higher levels of unprocessed folate in the blood, which is exactly the problem. High folic acid levels are what drive an increase in MMP-2.

On the other hand, taking a supplement that contains 5-methylTHF (also known as methylfolate) bypasses the need for this conversion. It’s like giving your body the exact fuel it needs, ready to go. This could potentially help keep the MMP-2 enzyme in check, alleviating the symptoms of hEDS.

Check Your Methylation Status

Since the advent of methylated B vitamins, clinicians have been finding that undermethylation due to a faulty MTHFR gene variant is not the only possibility. It is also possible for a person taking higher doses of methylated B vitamins over a period of time to become “overmethylated”. While the concept of overmethylation is not universally accepted in mainstream medicine, some clinicians and researchers in the field of functional medicine have observed this. Overmethylation can cause various symptoms, including anxiety, insomnia, and irritability.

When discussing lab tests related to methylation, there are both tests for your genetics and tests for your current methylation status. These include tests you can order online without a prescription:

A Potential Game-Changer: Could it Really Be Simple Vitamin Supplement?

In summary, when there’s a mutation in the MTHFR gene, as is the case with hEDS patients, there is a buildup of unprocessed folate and less of the active folate. Active folate helps control the MMP-2 enzyme. So, people with the mutation in the MTHFR gene have less active folate and high levels of inactive forms, which in turn lets MMP-2 run rampant. When MMP-2 gets out of hand, it starts breaking down a substance called decorin – the “glue” that keeps our tissues tightly held together. This cutting of decorin makes connective tissues looser and activates signals that lead to scarring. This ultimately results in the symptoms we associate with hEDS, like hypermobile joints and fragile skin.

Armed with this new understanding, researchers are now proposing that we may be able to manage hEDS symptoms by raising levels of active 5-methylTHF. Essentially, this just involves taking a supplement of the 5-methylTHF molecule, also known as methyl folate.

“You’ve got millions of people that likely have this, and until now, there’s been no known cause we’ve known to treat. It’s a big deal,”

Gregory Bix, MD, PhD – Tulane University

This isn’t just a game-changer; it’s a potential life-changer for the millions of people living with Ehlers-Danlos. And while more research is needed to fully validate this approach, the future of Ehlers-Danlos treatment is looking brighter than ever.

The What and Why of Ehlers-Danlos

Did you ever know a kid on the playground who could bend and twist themselves into strange positions? We used to call it “being double-jointed,” but that unusual flexibility can sometimes come from a condition you may not have heard of—Hypermobile Ehlers-Danlos Syndrome, or hEDS. This condition mainly affects the body’s connective tissue, which is like the glue that helps hold everything together. People living with hEDS can have unusually flexible joints and fragile skin, along with other symptoms that affect daily life in many ways.

Hypermobile Ehlers-Danlos Syndrome can create a range of health challenges. Many people feel tired all the time, which makes it hard to keep up with day-to-day activities. Joint pain is another common problem, and for some, it can go from mild discomfort to pain that never seems to let up. Some people with hEDS also have Postural Orthostatic Tachycardia Syndrome (POTS), which causes a rapid heartbeat and dizziness when they stand up. On top of that, joints may partially dislocate—a problem called subluxation—adding to pain and making movement more difficult.

Diagnosing and managing hEDS is far from simple. Because its symptoms can affect many parts of the body and seem so broad, doctors who don’t know much about hEDS sometimes mistake these patients for people just seeking attention, and they may be sent to mental health professionals instead. Standard tests often come back normal. Unlike some other conditions, there’s no clear lab test or genetic marker for hEDS, so people can spend years trying to get the right diagnosis. This long road can be exhausting. Many people give up trying to explain their symptoms because they have not felt heard or understood for so long.

The Breakthrough Discovery: Unusual Folate Levels and the MTHFR Connection

On the frontlines of learning more about Ehlers-Danlos, a group of researchers at Tulane University has shared an interesting finding. After caring for many people with hEDS at their clinic, they began to notice something unusual: these patients often had higher-than-normal levels of folic acid in their blood.

When they looked closer, they found that these high folate levels were often seen alongside changes in a gene called MTHFR. This gene helps the body make an enzyme that turns folate, a B vitamin, into a form the body can actually use

The link between high folate levels and changes in the MTHFR gene in people with Ehlers-Danlos came as a surprising insight. The research team then tied this finding to animal studies showing that 5-methylTHF, the active form of folate, helps turn off an enzyme called MMP-2. This enzyme, known as matrix metalloproteinase 2, breaks down a molecule called decorin — which acts like the glue that holds the framework around cells together. When decorin gets broken apart by MMP-2, the result is connective tissue that doesn’t stay firmly in place.

The Proposed Solution: Methylated Folate Supplements

The Tulane researchers’ findings suggest an interesting option for managing hEDS symptoms: a supplement containing 5-methyltetrahydrofolate, or 5-methylTHF. This is a form of folate that the body can use right away without needing the MTHFR enzyme to convert it first [PMC10122021]

Dr. Bix explained, “It’s an innocuous treatment. It’s not dangerous, and it’s a vitamin that can improve people’s lives. That’s the biggest thing: We know what’s going on here, and we can treat it.”

Dr. Bix

You might wonder, “Why not just eat more foods high in folate?” It’s a fair question. The folate we get from food still needs to be converted by the body into 5-methylTHF before it can be used. This is exactly where the process breaks down in people with hEDS because of the MTHFR gene change. So, eating more folate-rich food won’t necessarily raise usable 5-methylTHF levels. In fact, it could lead to higher levels of unprocessed folate in the blood, which is part of the problem since high folic acid levels can raise MMP-2.

Taking a supplement with 5-methylTHF, also known as methylfolate, skips this conversion step. It’s like giving the body the exact fuel it needs in a ready-to-use form. This might help keep MMP-2 under control and ease some hEDS symptoms.

Check Your Methylation Status

Since the introduction of methylated B vitamins, some clinicians have noticed that having a gene variant like MTHFR that slows methylation is not the only concern. It’s also possible for someone taking higher doses of methylated B vitamins over time to become “overmethylated.” While this idea is not fully accepted in mainstream medicine, some doctors and researchers in functional medicine have seen it in practice. Overmethylation can bring on symptoms like anxiety, trouble sleeping, and feeling more irritable than usual.

When it comes to testing for methylation, there are two main types: tests that look at your genes and tests that check your current methylation status. Many of these tests can be ordered online without needing a prescription.
