If you have an MTHFR variant and trouble sleeping, it can be tempting to assume that the answer to "Does MTHFR cause insomnia?" Is a simple "YES." Sadly, like everything else with MTHFR, it's complicated. MTHFR influences folate and one-carbon metabolism (methylation), which in turn affects homocysteine, methionine, S-adenosylmethionine (SAM), neurotransmitter biology and many methylation reactions throughout the body.Sleep itself also changes methylation patterns.

You get your bloodwork back and your homocysteine is elevated. If you've ever looked at Instagram ever your first thought is probably "It must be MTHFR!" You might be right, especially if you have an MTHFR C677T variant, which is most closely associated with high homocysteine. But there are many other reasons for homocysteine to be elevated, so don't stop looking once you see MTHFR.

Search for information about MTHFR online and you'll quickly encounter two very different messages. One group screams if you have an MTHFR variant, avoid folic acid and use methylfolate instead. The other group insists that people with MTHFR variants can process folic acid, so there is no reason to avoid it. Today, we'll explore the research and answer the question "Do you really need to avoid folic acid if you have MTHFR?"

When people think about estrogen, they usually think about how much of the hormone their body produces. But the other side of this story is how well your body processes and clears estrogen once it's been used. This process, called estrogen metabolism, is just as important as estrogen production itself. One of the body's most important tools for processing estrogen is methylation, a biochemical process supported by the MTHFR gene. MTHFR and hormones are linked.

MTHFR gene variants and hypothyroidism are often found together and several studies have looked at the link between the two, but the only real conclusion we can draw is that the connection is not simple. A 2022 meta-analysis published by Yang et. al. shows that C677T variants are associated with an increased risk of hypothyroidism, while A1298C variants are associated with a lower risk than the average population.

MTHFR is one of those topics that can send parents down a rabbit hole very quickly. A child has anxiety, allergies, ADHD symptoms, food sensitivities, a tongue-tie, a sacral dimple, or a “sugar bug” vein between the eyes, and suddenly the internet says: “It’s MTHFR.” While it may be MTHFR, the truth is far more nuanced and definitely less scary.

MTHFR and the gallbladder are linked, but not directly. Bile production and gallbladder function are deeply connected to liver metabolism, nutrient status, phospholipid production, inflammation, cholesterol balance, and methylation. That means common MTHFR gene variants may influence gallbladder health indirectly, not because MTHFR “controls the gallbladder,” but because methylation helps support several biochemical pathways that make healthy bile possible.

Living with an MTHFR gene mutation or methylation imbalance can feel overwhelming. You might be searching for answers, feeling tired, or struggling with symptoms that don’t seem to improve. That’s where an MTHFR health coach can make a real difference. But how do you find the right support, especially online? Let me walk you through the process so you feel confident and empowered every step of the way.

If you've been feeling off lately, struggling with unexplained fatigue, mood swings, or other hormone imbalances, you might be wondering if there’s a deeper cause. One possibility that often goes unnoticed is an MTHFR gene mutation, because MTHFR symptoms in females can present differently than they do in males.

Inflammation is a natural response by the body to injury or infection, but when it becomes chronic, it can contribute to many health problems. One factor linked to higher resting levels of inflammation is a genetic variation in the MTHFR gene. This post explores why MTHFR mutations may increase inflammation, reviews current research, and offers practical strategies to reduce inflammation naturally.

Living with the MTHFR gene mutation means paying close attention to your diet, especially when it comes to folate intake. Many people with this condition struggle to process synthetic folic acid found in fortified foods, so focusing on natural sources of folate is essential.

Autoimmune diseases such as psoriasis, multiple sclerosis (MS), and Hashimoto’s thyroiditis affect millions worldwide, often causing chronic inflammation and a range of debilitating symptoms. Emerging research suggests a link between mutations in the MTHFR gene and a higher risk of developing these autoimmune conditions

Breast implant illness (BII) has gained attention as more people report a range of unexplained symptoms after receiving breast implants. While breast implants are generally considered safe, some individuals experience persistent health issues that they associate with their implants. Recent research suggests a possible link between BII and genetic factors, particularly the MTHFR gene mutation

Blood clotting disorders can pose serious health risks, including stroke, deep vein thrombosis, and pulmonary embolism. One genetic factor that influences clotting risk is the MTHFR gene mutation

Understanding the role of zinc in supporting methylation can help those with MTHFR mutations improve their methylation balance and overall well-being.

The connection between MTHFR gene mutations and blood clot risk often centers on homocysteine levels. The common story goes like this: if you have an MTHFR mutation, your homocysteine will be high, and that means you face a greater risk of blood clots. But this narrative oversimplifies a complex relationship.

Brain fog is a frustrating symptom that many people experience without fully understanding its causes. It often feels like a cloud over your thinking, making it hard to focus, remember details, or process information clearly. One key factor linked to brain fog is blood sugar instability. When blood sugar levels swing too high or too low, the brain struggles to function optimally. Another important piece of this puzzle is the MTHFR gene variance, which can influence how the bo

When you receive blood test results showing high folate levels, it might seem positive at first. However, it can signal a potential issue with MTHFR (methylenetetrahydrofolate reductase) function and highlight risks related to unmetabolized folic acid (UMFA) buildup in the bloodstream.

Brain fog makes all of life more difficult because normal tasks become an uphill battle of hazy focus, forgotten pieces, and slow or stalled thought processes. The connection between MTHFR (methylenetetrahydrofolate reductase), blood sugar changes, and brain fog can help you beat this symptom for good.

Navigating nutrition can be confusing, especially for those dealing with the MTHFR gene mutation. This mutation can impact how effectively your body processes certain nutrients, raising the question: is a whole-food diet sufficient, or do you need to introduce supplements? Let's explore this important topic and discover the best nutritional strategy for individuals with MTHFR mutations. Understanding MTHFR and Its Implications The MTHFR gene produces an enzyme critical for pr
