Vitamin B6 is a vital nutrient that helps your body turn food into energy, supports brain function, and keeps your immune system strong.

📋 About This Biomarker

Vitamin B6 is like a versatile assistant in your body, helping with a wide range of essential tasks to keep you feeling your best. Think of it as a multitool that aids in converting the food you eat into energy, supports your nervous system, and helps produce important brain chemicals like serotonin, which influences mood and sleep patterns.It's also crucial for making haemoglobin, the protein in red blood cells that carries oxygen throughout your body, ensuring that all your tissues get the oxygen they need. Vitamin B6 supports your immune system too, helping you fight off infections and stay healthy. By measuring your Vitamin B6 levels, we can see if your body has enough of this important nutrient to support these vital functions. Whether you're feeling unusually tired, experiencing mood changes, or just want to make sure you're on the right track, checking your Vitamin B6 levels can provide valuable insights into your overall health.

🎯 Why We Test This

Testing your Vitamin B6 levels helps make sure your body has enough of this essential vitamin to do its many jobs. It's especially important if you're feeling unusually tired, having mood changes, or getting sick more often, or if you have conditions that might affect how your body uses Vitamin B6, like digestive disorders or heavy alcohol use.Knowing your levels can help you catch any shortages or excesses early, so you can adjust your diet or supplements and keep your health on track.

⚠️ What Affects It

Several factors can influence Vitamin B6 levels in your body. Your diet plays a big role - if you aren't eating enough foods rich in Vitamin B6, like chicken, fish, potatoes, and bananas, your levels might be low. Conditions that affect how well your body absorbs nutrients, such as coeliac disease or inflammatory bowel disease, can also lower your Vitamin B6 levels.Certain medications, like some treatments for epilepsy or asthma, might interfere with how your body uses Vitamin B6. Drinking too much alcohol can reduce Vitamin B6 levels because alcohol makes it harder for your body to absorb and use this vitamin. Life stages like pregnancy and breastfeeding increase the body's need for Vitamin B6, so if you're expecting or nursing, you might need more than usual. Understanding these factors can help explain why Vitamin B6 levels might be higher or lower than expected and guide steps to keep them in a healthy range.

📈 How to Improve

If your Vitamin B6 levels are high or getting close to being high, it's important to look at how much you're taking in supplements and consider reducing them under the guidance of a healthcare professional. This helps prevent side effects like nerve damage.If your levels are low or nearing the low end, you can boost them by eating more Vitamin B6-rich foods. Good choices include chicken, turkey, fish like salmon and tuna, whole grains, chickpeas, bananas, and potatoes. Sometimes, your doctor might recommend a Vitamin B6 supplement, especially if changing your diet isn't enough or if your body has trouble absorbing nutrients.Working with a healthcare provider and regular check-ups can help you adjust your intake and keep your Vitamin B6 levels in the healthy range.

📊 Understanding Your Results (nmol/L)

Low (< 20 nmol/L)
When Vitamin B6 levels are below normal, it suggests a deficiency that could affect your health. Low Vitamin B6 can make you feel tired, irritable, or weak, and in serious cases, it can cause anaemia or even seizures. It can also weaken your immune system, making it harder to fight off infections.This deficiency can happen if you're not eating enough Vitamin B6-rich foods, if your body isn't absorbing nutrients well, if you drink too much alcohol, or if certain medications interfere with Vitamin B6 in your body. To fix this, you'll likely need to eat more Vitamin B6-rich foods and might need supplements as advised by a healthcare professional.
Optimal (20 - 125 nmol/L)
Having Vitamin B6 levels within the normal range is great news - it means your body has just the right amount of this essential vitamin to support its many important roles. This balance helps your metabolism work properly, keeps your nervous system healthy, and supports a strong immune system. It's a sign that your diet and lifestyle are providing what your body needs to stay healthy and function well. If your Vitamin B6 levels are nearing the top of the normal range, it means you're getting plenty of this nutrient - maybe even a bit too much. While your body needs Vitamin B6, having too much isn't necessarily better. Staying just below the high end is generally safe, but it's a good idea to keep an eye on your intake of supplements or fortified foods to make sure you're not overdoing it. This helps you avoid potential issues like nerve problems that can come from having too much Vitamin B6. If your Vitamin B6 levels are getting close to the lower end of the normal range, it might be a hint that you're not getting quite enough. While you might not have any symptoms yet, it's a good idea to start eating more foods rich in Vitamin B6, like chicken, fish, whole grains, and certain fruits and vegetables. Taking action now can help you keep your levels in the healthy range and support your overall well-being.
High (> 125 nmol/L)
When Vitamin B6 levels are higher than normal, it might seem harmless, but too much can actually cause problems. Excessive Vitamin B6 can lead to nerve damage, which might make your hands and feet feel tingling or numb - a condition known as peripheral neuropathy.High levels are usually due to taking too many Vitamin B6 supplements, not from food alone, since it's hard to get too much from your diet. If your levels are high, it's important to check any supplements you're taking and talk to a healthcare professional about adjusting them to prevent potential side effects.
