Which items are measured in the Vitamin Total test?

Vitamin A
Vitamin A is crucial for vision, immune function, and skin health. It helps with eyesight, especially in low light, and keeps skin and mucous membranes healthy. Vitamin A is in foods like carrots, sweet potatoes, and leafy greens. Animal sources include liver and dairy products. Too little can lead to vision problems and a weak immune system. Vitamin A also supports growth and reproduction.
Vitamin B3
Vitamin B3, also known as niacin, is important for converting food into energy. It's key for the health of your skin, nerves, and digestive system. B3 is in meat, fish, poultry, and whole grains. Some people may need supplements, especially with certain medical conditions. A lack of B3 can lead to skin issues, tiredness, and confusion. B3 helps maintain cholesterol levels and supports overall health.
Vitamin B5
Vitamin B5, also known as pantothenic acid, is key for making energy from food. It helps the body use carbs, proteins, and fats. B5 is in meats, avocados, broccoli, and whole grains. It's rare to lack B5, but it's important for skin health and wound healing. B5 supports the nervous system and reduces stress.
Vitamin B12
Vitamin B12, or cobalamin, is a water-soluble vitamin essential for red blood cell formation, nervous system health, and energy metabolism. It's unique in containing the metal cobalt and is found naturally in animal products like meat, fish, poultry, eggs, and dairy. Vegetarians and vegans may need fortified foods or supplements, as B12 is scarce in plant-based diets.
Vitamin D
Vitamin D is a fat-soluble vitamin essential for maintaining healthy bones and teeth, supporting the immune system, and playing a role in muscle function. It's unique among vitamins because the body can produce it when exposed to sunlight.
Vitamin E
Vitamin E is a fat-soluble antioxidant important for protecting cells from damage, supporting immune function, and maintaining skin and blood vessel health. It's found in foods like vegetable oils, nuts, seeds, and green leafy vegetables. While deficiency is rare, it can lead to neurological issues.
Biotin, or vitamin B7, is vital for turning food into energy and supports healthy skin, hair, and nails. It's key in metabolizing fats, carbohydrates, and proteins. Biotin deficiency is rare, but supplements are often used to enhance hair and nail health.
Folate (folic acid)
Folate, also known as folic acid, is vital for cell growth and making DNA. It's key for pregnant women to prevent birth defects. Folate is in leafy greens, fruits, beans, and fortified foods. Supplements are common for pregnancy and some health conditions. A lack of folate can lead to tiredness and weak immunity.
Coenzyme Q10
Q10, or CoQ10, is a crucial compound for energy production in every human cell and also acts as an antioxidant to protect cells from damage. It's vital for maintaining overall health and cellular function.

Recognizing Symptoms of Vitamin Deficiency

Vitamin deficiencies often develop slowly, with symptoms appearing long after the deficiency has begun. General symptoms include fatigue, dry skin and hair, depression, and irritability. However, specific deficiencies lead to unique symptoms based on each vitamin's function.

Overview of Vitamins in GetTested's Test

Vitamin A (Retinol)
Vitamin A is crucial for vision, supporting the immune system, and maintaining healthy skin. Deficiency, mainly due to inadequate diet or chronic diarrhoea, leads to night blindness, dry eyes, and skin, and in severe cases, infertility.

Vitamin B3 (Niacin)
This nutrient helps convert food into energy. A deficiency in Vitamin B3, often caused by a diet low in tryptophans, can result in skin rashes, diarrhoea, headaches, and depression.

Vitamin B5 (Pantothenic Acid)
Vitamin B5 plays a key role in metabolizing fats and carbohydrates and producing red blood cells and hormones. Deficiency, rare but more common in alcoholics and those on oral contraceptives, can lead to insomnia, depression, and stomach pains.

Vitamin B7 (Biotin)
Essential for metabolizing carbohydrates, fats, and amino acids, biotin also strengthens hair and nails. A deficiency, which may occur in Crohn’s disease or Colitis, leads to thinning hair, skin rashes, and brittle nails.

Folate (Vitamin B9)
Folate is necessary for DNA synthesis and cell division, especially crucial during pregnancy. A lack of folic acid in the diet can result in fatigue, weakness, and neurological problems.

Cobalamin (Vitamin B12)
Cobalamin is vital for energy metabolism, red blood cell production, and DNA synthesis. Deficiency, common in those avoiding meat, eggs, or milk, causes tiredness, weakness, and lightheadedness.

Vitamin D3 (25OH)
This nutrient bolsters the immune system, aiding in calcium and phosphorus absorption for strong bones. Deficiency, primarily due to low sunlight exposure, can weaken bones and increase fracture risk.

Vitamin E (Alpha-Tocopherol)
Vitamin E acts as an antioxidant, protecting cells and tissues. Although rare, deficiency can damage nerves and muscles and weaken the immune system, usually due to an inadequate diet.

Coenzyme Q10
An antioxidant crucial for converting food into energy, Q10 deficiency, mostly due to genetic defects, can cause neurological issues.

Who should get a Vitamin Total test?

A Vitamin Total test, assessing levels of vitamins A, B3, B5, B12, D, E, Biotin, Folic Acid, and Q10, is highly beneficial for individuals with restrictive diets, like vegans or vegetarians, who might be at risk for deficiencies in these specific vitamins. People with gastrointestinal disorders affecting nutrient absorption, such as Crohn’s disease or celiac disease, also stand to benefit. Moreover, the elderly and those experiencing symptoms like fatigue, skin problems, or cognitive issues should consider this test, as these symptoms can indicate vitamin deficiencies.
