What is methylation and why does it matter?
Have you heard of methylation? It’s a bit of a buzz word in the natural health space, and while it can sound complicated, the concept is actually quite simple.
Methylation is the transfer of a small chemical group (called a methyl group) from one molecule to another. This process happens constantly in the body and helps regulate a wide range of normal functions¹.
These reactions occur millions of times throughout the body and play an important role in maintaining general health and wellbeing.
Key functions supported by methylation
Methylation is involved in many everyday processes in the body, including:
- Supporting nervous system and brain function
- Contributing to normal energy production
- Assisting the body’s natural detoxification processes
- Supporting DNA production and repair
- Helping maintain healthy immune system function
- Supporting the body’s response to stress
- Assisting in the production of important compounds such as glutathione¹
Because methylation touches so many systems, adequate nutritional support is important for overall wellbeing.
What happens when methylation support is inadequate?
When the body does not have enough of the nutrients required to support methylation, some people may experience symptoms such as:
- Low energy
- Changes in mood
- Reduced stress tolerance
- General feelings of fatigue or poor wellbeing
It’s important to note that these symptoms can have many causes, and if you are concerned, you should speak with a healthcare professional.
How do you assess methylation?
If needed, your doctor may assess certain markers that relate to methylation, such as:
- Vitamin B12 levels
- Folate levels
- Homocysteine levels²
These markers can help give an indication of whether dietary intake of key nutrients is adequate.
The key nutrients involved in methylation
Several nutrients are involved in supporting methylation, particularly:
- Vitamin B6
- Folate (Vitamin B9)
- Vitamin B12
These vitamins work together in the body and are commonly found in a balanced diet or in B complex supplements³⁴.
What about “active” forms of B vitamins?
You may have come across terms like:
- Pyridoxine-5-phosphate (active B6)
- 5-methyltetrahydrofolate (active folate)
- Methylcobalamin (active B12)
These are forms of B vitamins that the body can use directly.
In many cases, the body is able to convert standard forms of B vitamins into their active forms as needed. However, individual requirements can vary, and some people may prefer different or the active forms depending on their nutritional needs.
Some formulations provide these vitamins in different forms depending on the intended use of the product. If you are unsure which option is right for you, speak with a healthcare professional.
B vitamins and homocysteine metabolism
Vitamins B6, B12 and folate are involved in the normal metabolism of homocysteine in the body ²,⁸.
Supporting adequate intake of these nutrients may help maintain homocysteine levels already within the normal range, which is one aspect of maintaining cardiovascular system health.
Supporting your intake of B vitamins
If dietary intake is inadequate, supplementation may help support levels of key B vitamins.
A vitamin B complex supplement can help provide a range of B vitamins that work together to support general health and wellbeing⁹.
Some formulations may also include different forms of these vitamins, depending on the product.
Dietary sources of B vitamins
You can also support your intake of B vitamins through your diet. Foods rich in B vitamins include:
- Leafy green vegetables
- Legumes and whole grains
- Eggs and dairy
- Meat, poultry and seafood
- Nuts and seeds
A varied, balanced diet is the foundation of good nutritional status.
Lifestyle tips to support overall wellbeing
In addition to diet, general lifestyle habits may help support overall health:
- Limiting highly processed foods
- Moderating alcohol intake
- Supporting gut health through a varied diet
- Managing stress levels
Choosing the right B vitamin support
When considering a supplement, it’s important to choose one that suits your individual needs.
- A B complex can help support general B vitamin intake and homocysteine metabolism
- Some formulations provide different forms of B vitamins, depending on the product
- If you are unsure which option is right for you, speak with a healthcare professional
Final thoughts
Methylation is a normal process that supports many functions in the body, and adequate intake of key nutrients such as B6, B12 and folate plays an important role in maintaining overall health and wellbeing.
Focusing on a balanced diet, along with appropriate supplementation where needed, can help support your nutritional needs.
Always read the label and follow the directions for use. If symptoms persist, talk to your health professional. This information is general in nature and is not intended to replace professional medical advice.
