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?"

If you've had genetic testing and discovered an MTHFR variant, there's a good chance your report mentions one or both of two names: C677T and A1298C. These are both variances in the same gene, MTHFR, but these two variants aren't the same (see the magic chair analogy for a simple explanation). They affect the MTHFR enzyme differently, and their practical significance can vary considerably. The question of MTHFR C677T vs. MTHFR A1298C is more complex.

Most conversations about blood sugar focus on carbohydrates, insulin, body weight, and exercise. These are all important, but glucose regulation is also influenced by quieter biochemical processes taking place inside every cell, including methylation. Methylation is one of the places where MTHFR and blood sugar intersect.

Understanding the difference between these two conditions can prevent unnecessary fear while also helping families recognize when true medical evaluation is needed.

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.

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

Creativity often feels like a mysterious gift, something that flows naturally in some people but not in others. Recent discussions in genetics suggest that a mutation in the MTHFR gene might play a role in shaping creative abilities.

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.

Sunlight and folate have a complicated relationship, and new research has showed that the more UV exposure you have, the lower your red blood cell folate levels will be. Protect your folate status this summer!

Naturally, MTHFR and birth control pills interact. It's not like this is an easy mutation to live with in other senses; why would it leave our contraceptive options untouched? Complaining aside, I could have saved myself years of miserable experiences with the pill if I had known this when I was in University.
