Our Vitamin Deficiencies
Check-up
Modern lifestyles and dietary choices can lead to imbalances, leaving you vulnerable to a range of health problems. While vitamin deficiencies can manifest in various ways, some common symptoms include fatigue, weakened immune system, hair loss, skin problems, and difficulty concentrating.
Our Vitamin Deficiencies Check-up gives you a precise picture of your vitamin status across 5 essential biomarkers — so you can stop guessing and start acting on the right information.
Why it matters
What vitamin
deficiencies
are there?
What kind of vitamin deficiency makes you tired? While vitamin deficiencies can manifest in various ways, some common symptoms include fatigue, weakened immune system, hair loss, skin problems, and difficulty concentrating. Understanding your vitamin levels is essential for taking proactive steps to improve your health.
Vitamin D Deficiency
Known as the "sunshine vitamin," vitamin D is essential for calcium absorption, bone health, and immune function. Deficiency can weaken bones, raising fracture and osteoporosis risks, and may cause fatigue, muscle weakness, and mood disorders like depression.
Vitamin B12 Deficiency
Vital for nerve function, DNA synthesis, and red blood cell production, vitamin B12 mainly comes from animal products. A deficiency can cause fatigue, weakness, numbness, balance issues, and cognitive difficulties. Prolonged deficiency may lead to serious neurological problems.
Folic Acid (Vitamin B9) Deficiency
Folic acid is crucial for DNA synthesis and cell development, especially during pregnancy. A deficiency raises the risk of neural tube defects in the fetus and can cause megaloblastic anemia, which leads to fatigue, weakness, and shortness of breath.
Vitamin A Deficiency
Essential for vision, immune function, and skin health, a lack of vitamin A can lead to night blindness, increased infection risk, and dry skin.
Vitamin E Deficiency
Vitamin E is essential for protecting cells against oxidative damage. A deficiency may cause muscle weakness, vision problems, and impaired immunity. By addressing deficiencies early on, you can prevent a cascade of health issues and enhance your overall well-being.
5 biomarkers
What your
blood reveals
Our Vitamin Status Check shows your vitamin levels clearly. We analyze important vitamins like folic acid, B12, D, A, and E to determine your nutritional health and find any imbalances that could affect your well-being. These vitamins are vital for functions such as forming red blood cells, promoting bone health, supporting energy, and boosting immunity.
Known as the "sunshine vitamin," vitamin D is essential for calcium absorption, bone health, and immune function. In Switzerland, deficiency is extremely prevalent during autumn and winter months. Low levels are directly linked to fatigue, muscle weakness, low mood and increased susceptibility to infection — and are among the most common and most frequently overlooked nutritional issues in adults.
Vital for nerve function, DNA synthesis, and red blood cell production, vitamin B12 mainly comes from animal products — making deficiency particularly common among vegetarians and vegans. A deficiency can cause fatigue, weakness, numbness, balance issues, and cognitive difficulties. Prolonged deficiency may lead to serious neurological problems that are difficult to reverse.
Folic acid is crucial for DNA synthesis and cell development, especially during pregnancy. A deficiency raises the risk of neural tube defects in the fetus and can cause megaloblastic anemia, which leads to fatigue, weakness, and shortness of breath. Folic acid also works alongside B12 in the methylation cycle, which affects mood, energy and cognitive function.
Essential for vision, immune function, and skin health, a lack of vitamin A can lead to night blindness, increased infection risk, and dry skin. Vitamin A is a fat-soluble vitamin stored in the liver, and both deficiency and excess can have clinical consequences — making a blood test the only reliable way to assess your true status.
Vitamin E is essential for protecting cells against oxidative damage — it is one of the body's primary antioxidant defences. A deficiency may cause muscle weakness, vision problems, and impaired immunity. As a fat-soluble vitamin, levels are influenced by dietary fat intake and absorption capacity, and deficiency is often missed without targeted testing.

Who it's for
Who might have
increased
vitamin needs?
Certain groups may have higher vitamin requirements. If you fall into one of these categories, a Vitamin Check-Up is especially relevant to ensure optimal health and prevent long-term deficiencies. Even with a seemingly balanced diet, vitamin deficiencies can occur due to poor nutrient absorption, chronic stress, medications, or individual metabolic needs.
Pregnant & breastfeeding women
Significantly elevated requirements for folic acid, B12, D and A during pregnancy and nursing — deficiencies have direct consequences for the developing fetus.
Vegans & vegetarians
Plant-based diets eliminate the primary dietary sources of B12 and reduce intake of D, A and E. Regular testing is essential to prevent neurological and haematological complications.
Athletes
High physical demand increases vitamin turnover. Deficiencies in B12, D and E directly impair energy metabolism, recovery, and immune function in active individuals.
Older adults
Absorption of B12, D and A declines with age. Deficiencies are extremely common in adults over 60 and are frequently responsible for fatigue, cognitive decline and increased fracture risk.
People on long-term medication
Many common medications interfere with vitamin absorption — including proton pump inhibitors, metformin, and oral contraceptives, which deplete B12, B9 and D.
People under chronic stress
Prolonged stress depletes B vitamins and disrupts metabolic pathways. Modern food quality and lifestyle make it harder to get all essential nutrients from diet alone.
