Vitamin B6 is part of the B complex of vitamins The body is unable to make this vitamin itself and so instead takes it in through diet
Customize TestGood nutrition is the foundation of good health. For your body and mind to function at their best, you need the right balance of vitamins, minerals, and nutrients every single day. When your levels drop too low, it can affect your energy, mood, immunity, and overall wellbeing. A Vitamin B6 Blood Test helps you understand whether your diet and lifestyle are providing the essential nutrition your body needs.
Vitamin B6, also known as pyridoxine, is one of the most important members of the B complex family. Your body cannot produce this vitamin on its own, which means you must get it from food or supplements. Because absorption varies from person to person, checking your levels through a blood test is the most reliable way to ensure you are getting enough.
Many people wonder vitamin b6 is for what, especially when exploring their nutritional health. Vitamin B6 plays a central role in more than one hundred enzyme reactions in the body. It helps convert food into energy, supports neurotransmitter production, maintains healthy nerve function, and contributes to the formation of haemoglobin. Without enough B6, several essential processes slow down, leaving you tired, unfocused, or nutritionally imbalanced.
Understanding vitamin b6 is good for what helps highlight how essential this nutrient is. Vitamin B6 supports cognitive function, hormonal balance, immune response, and protein metabolism. It is involved in producing serotonin and dopamine, which are important for mood stability and mental clarity. This makes B6 especially important for individuals experiencing stress, low mood, or fatigue.
A Vitamin B6 Blood Test helps identify nutritional deficiencies or imbalances before they lead to symptoms. Many people follow a healthy diet but still develop low levels due to absorption issues, digestive problems, medication use, stress, or lifestyle demands.
This test is especially useful for individuals who experience:
Frequent fatigue or low energy
Mood swings or irritability
Muscle weakness
Poor concentration
Numbness or tingling in hands or feet
Reduced immunity
Difficulty handling stress
Sleep disruption
Because B6 plays a critical role in nerve health, a deficiency may contribute to symptoms associated with nerve irritation. This is why some clinical research discusses vitamin b6 for neuropathy and how balanced B6 levels can support nerve function.
Youth Revisited provides flexible testing options so you can choose the method that suits your lifestyle. You can take this blood test as:
A simple test Kit delivered to your home. You collect your sample and return it to our laboratory.
A trained phlebotomist visits your home to collect a professional venous blood sample. This option is ideal for individuals who prefer convenience or find it difficult to travel.
If you prefer a clinical setting, you can visit one of our partnered clinics for sample collection.
Once your sample arrives at the lab, it is analysed for Vitamin B6 concentration, and you receive a clear, easy to understand results report.
Vitamin B6 deficiency can appear in several ways because it influences energy, nerves, mood, and immunity. You may notice:
Constant tiredness or low stamina
Poor immune response or frequent illnesses
Pins and needles, tingling, or numbness
Cracked lips or skin irritation
Headaches or dizziness
Trouble concentrating
Irritability or anxiety
Hormonal fluctuations
These symptoms may not always seem related, which is why blood testing gives a clearer picture. Identifying low B6 early helps you correct your levels before symptoms become more severe.
Vitamin B6 is present in foods such as poultry, fish, eggs, nuts, oats, bananas, chickpeas, and fortified cereals. Still, modern diets, stress, digestive concerns, and lifestyle habits may affect your absorption.
Some people also ask about the recommended daily dose of vitamin b6. This varies depending on age, gender, and health status, but adults generally need around one to two milligrams per day. Your personalised test report may guide you further based on your individual needs.

It is also helpful for people undergoing routine health checks, those who suspect nutritional deficiency, or individuals managing conditions influenced by nerve and energy function.
After you receive your results, take time to review the explanation provided in your report. If your Vitamin B6 level is low or borderline, you may consider dietary adjustments or supplementation. You may also review your lifestyle, stress level, or medications that could be influencing absorption. For individuals with symptoms or multiple deficiencies, a full nutritional panel may be recommended.
