Vitamin Test (A, B3, B5 & Biotin)
£150.00
A Targeted Assessment of Overlooked Nutrients
Not all vitamin deficiencies are easy to detect—or routinely tested for. While many focus on B12 or D, other critical nutrients like vitamin A, niacin (B3), pantothenic acid (B5), and biotin (B7) often go unchecked. Yet deficiencies in these vitamins can significantly impact energy levels, skin health, cognitive performance, and overall metabolic function.
The Vitamin A, B3, B5 & Biotin Test by GetTested is designed to fill that gap. Whether you're following a restricted diet, managing fatigue, or dealing with recurring skin or hair concerns, this test helps you uncover the lesser-known nutritional imbalances that may be holding you back.
What’s Included in the Test?
This lab-based blood test analyses four essential nutrients that play diverse roles in cellular health and daily functioning:
Vitamin A (Retinol) – A fat-soluble vitamin crucial for vision, immune function, and skin integrity. Deficiency can cause dry skin, night blindness, and delayed healing.
Vitamin B3 (Niacin) – Supports energy production and nervous system health. Low levels may lead to fatigue, depression, and skin sensitivity.
Vitamin B5 (Pantothenic Acid) – Involved in hormone production, fat metabolism, and red blood cell synthesis. Deficiency can result in mood swings, poor focus, and digestive discomfort.
Biotin (Vitamin B7) – Promotes strong hair and nails, supports macronutrient metabolism, and maintains skin health. A deficiency may present as thinning hair, brittle nails, or rashes.
Why These Vitamins Matter
These vitamins may not receive the same attention as B12 or D, but their roles in maintaining everyday health are equally important. Vitamin A, for instance, is fundamental to vision and tissue repair. B3 and B5 help convert food into usable energy and support neurological function. Biotin, often marketed for beauty benefits, is also a key player in cellular metabolism and nervous system support.
Many people with unexplained fatigue, skin flare-ups, or hair thinning may not realise that suboptimal levels of these vitamins are contributing to their symptoms. This test provides a simple way to check for those deficiencies without the need for clinical appointments or guesswork.
Who Should Take This Test?
This test is ideal for individuals who:
Are experiencing persistent fatigue, skin problems, or hair loss
Follow vegan, vegetarian, or otherwise restricted diets
Have digestive conditions that impair nutrient absorption, such as Crohn’s or coeliac disease
Are focused on preventive care and optimising overall nutritional health
