About this test

Three reasons the Comprehensive Vitamin Profileis right for you

  • It provides a detailed overview of your vitamin levels, covering key B vitamins, fat-soluble vitamins, and cofactors
  • Helps identify deficiencies that may affect energy, mood, immune function, and overall health
  • Allows targeted dietary or supplement interventions for optimal wellness

Why check your vitamin levels?

Vitamins are essential nutrients your body needs for metabolism, nerve function, red blood cell production, and immune defence. Even mild deficiencies can impact your energy, focus, and general wellbeing.

Factors such as diet, lifestyle, certain medications, and absorption issues can reduce vitamin levels. Testing helps pinpoint areas where your body may need support.

  • Supports energy production and mental clarity
  • Identifies potential risk for anaemia or nerve-related issues
  • Guides safe and effective supplementation or dietary adjustments

What symptoms might indicate a vitamin deficiency?

Deficiencies can present in many ways, depending on which vitamins are low and how severe the deficiency is. Common indicators include:

  • Fatigue or low stamina
  • Mood changes, irritability, or difficulty concentrating
  • Muscle cramps, weakness, or tingling in extremities
  • Pale skin, brittle nails, or hair thinning
  • Poor immune response or frequent infections
  • Vision problems or sensitivity to light (Vitamin A)
  • Bone or joint discomfort (Vitamin D)

How does the Comprehensive Vitamin Profilework?

This blood test evaluates a broad range of vitamins to give an accurate picture of your nutritional status. It includes:

  • Vitamin A (Retinol)
  • Beta Carotene
  • Vitamin B1 (Thiamine)
  • Vitamin B2 (Riboflavin)
  • Vitamin B3 (Nicotinamide)
  • Vitamin B6 (Pyridoxine)
  • Vitamin B9 (Folic acid) - Red cell measurement
  • Vitamin B12 (Active form)
  • Vitamin D (25-OH)
  • Vitamin E (Alpha Tocopherol)

The test detects deficiencies, imbalances, or excesses, allowing your healthcare provider to recommend lifestyle, dietary, or supplement strategies tailored to your needs.

What can I expect at my appointment?

Your appointment involves a routine blood sample taken by a trained professional. The procedure is quick and minimally invasive.

No fasting or special preparation is required. After testing, you will receive a detailed report outlining your vitamin levels and actionable guidance for improvement.
