Description
A broad Vitamin Blood Test
A Vitamin Blood Test gives you a clear picture of your nutritional health by measuring the levels of essential vitamins in your bloodstream. These vitamins play a vital role in everything from energy production and immune support to brain function, bone health, and mood regulation. If you’re low in certain vitamins, you might experience symptoms like fatigue, low mood, brain fog, hair thinning, brittle nails, or frequent colds—often without realising a deficiency is to blame.
This test is especially useful if you’ve been feeling unwell without a clear reason, if you follow a restricted diet such as vegan, vegetarian, or low-carb, or if you take medications that could interfere with nutrient absorption. It’s also a smart choice if you’re recovering from illness, managing a long-term condition, or simply looking to optimise your health, improve energy, or support your immune system and mental clarity.
Commonly measured vitamins are crucial for the healthy functioning of your body. Even mild deficiencies can have a significant impact on how you feel each day, but the good news is that most imbalances can be corrected with the right changes.
A vitamin blood test takes the guesswork out of your health. Whether you’re trying to find the cause of persistent symptoms or want to stay on top of your wellbeing, this test gives you the insights you need to take control — so you can feel more energised, focused, and resilient.
How often should I have a Vitamin blood test?
We recommend checking your Vitamin levels annually unless you experience any health changes or commence a weight loss programme which involves a restricted diet.

Vitamin B1 (Thiamine)
A Vitamin B1 Blood Test checks the level of thiamine in your blood — an essential B vitamin your body needs to turn food into energy. Thiamine plays a key role in nerve function, muscle health, and brain activity, and your body can’t store much of it, so you need a regular supply through your diet.
Vitamin B2
A Vitamin B2 Blood Test measures the amount of riboflavin in your blood — a B vitamin that helps your body produce energy, supports healthy skin and eyes, and plays a key role in cell growth and metabolism. Riboflavin also helps the body process other B vitamins, including B6 and folate.
Vitamin B6 (pyridoxine)
A Vitamin B6 Blood Test checks your levels of pyridoxine — a vital B vitamin involved in brain function, mood regulation, red blood cell production, and how your body uses protein, carbohydrates, and fats. It also supports your nervous and immune systems.
Beta-Carotene
A Beta-Carotene Blood Test measures the level of beta-carotene in your blood — a powerful antioxidant and a key source of vitamin A. Found naturally in colourful fruits and vegetables like carrots, sweet potatoes, and spinach, beta-carotene helps support your vision, immune system, and skin health.
Vitamin A (Retinol)
A Vitamin A Blood Test measures the amount of vitamin A in your bloodstream — a fat-soluble vitamin that’s essential for healthy vision, immune function, reproduction, and skin health. It also plays a key role in the growth and repair of cells throughout the body.
Vitamin C
A Vitamin C Blood Test measures the level of ascorbic acid (vitamin C) in your blood — a powerful antioxidant that’s vital for immune defence, collagen production, wound healing, and the absorption of iron. It also helps protect your cells from oxidative stress.
Vitamin E (alpha Tocopherol)
A Vitamin E Blood Test measures the level of alpha-tocopherol,( the most active form of vitamin E) in your blood. As a powerful antioxidant, vitamin E helps protect your cells from damage, supports immune function, and plays a role in skin and eye health, as well as nerve and muscle function.
