Vitamins

Vitamin E is a fat-soluble antioxidant that helps protect cells from damage and supports immune function. It also plays a key role in maintaining healthy skin and blood vessels. Vitamin E is commonly found in foods such as vegetable oils, nuts, seeds, and green leafy vegetables. Although deficiency is uncommon, it can lead to neurological problems.

Vitamin E

Nicotinic acid (niacin or vitamin B3) is an essential nutrient that helps convert food into energy and supports healthy skin, nerve function, and digestion. It’s naturally found in foods like meat, fish, and grains, and can also be produced from the amino acid tryptophan. A deficiency in nicotinic acid can lead to pellagra, a condition characterized by diarrhea, dermatitis, and dementia.

Nicotinic acid

Vitamin B12, or cobalamin, is a water-soluble vitamin essential for red blood cell production, nervous system function, and energy metabolism. It uniquely contains the metal cobalt and is naturally found in animal-based foods such as meat, fish, poultry, eggs, and dairy. Since B12 is limited in plant-based diets, vegetarians and vegans often need fortified foods or supplements to meet their requirements.

Vitamin B12

CoQ10 (Coenzyme Q10) is a crucial compound that plays a key role in energy production within every cell of the body. It also acts as a powerful antioxidant, helping to protect cells from oxidative damage. CoQ10 is essential for supporting overall health and proper cellular function.

Coenzyme Q10

Folate, also known as folic acid, is a vital B-vitamin essential for cell growth and DNA synthesis. It plays a crucial role during pregnancy in helping to prevent birth defects. Folate naturally occurs in leafy greens, fruits, beans, and fortified foods. Supplements are commonly used during pregnancy and for certain health conditions. A folate deficiency can lead to fatigue and a weakened immune system.

Folate (folic acid)

Vitamin A is a vital nutrient that supports vision, immune defense, skin health, and reproductive function. It plays an important role in night vision, maintaining healthy mucous membranes, and promoting normal growth. Found in foods like carrots, sweet potatoes, leafy greens, liver, and dairy products, a deficiency in Vitamin A can result in impaired vision, weakened immunity, and skin problems.

Vitamin A

Biotin, also known as vitamin B7, is an essential nutrient that helps the body convert food into energy. It plays a crucial role in metabolizing fats, carbohydrates, and proteins, while also supporting healthy skin, hair, and nails. Although biotin deficiency is rare, supplements are often used to enhance hair and nail strength.

Biotin

Vitamin B3 (Niacin) is a vital nutrient that helps convert food into energy and supports the health of the skin, nervous system, and digestive tract. It is found in foods such as meat, fish, poultry, and whole grains. Niacin also helps maintain healthy cholesterol levels and overall metabolic function. Deficiency can cause fatigue, skin issues, and cognitive problems, and supplementation may be necessary for certain health conditions.

Vitamin B3

Vitamin D is a fat-soluble vitamin that is crucial for maintaining healthy bones and teeth, supporting the immune system, and assisting muscle function. Unlike most vitamins, the body can produce vitamin D when the skin is exposed to sunlight, making it unique in how it is obtained and used.

Vitamin D

Vitamin B5, also known as pantothenic acid, is an essential nutrient that helps the body turn food into energy by supporting the metabolism of carbohydrates, proteins, and fats. Found in foods such as meats, avocados, broccoli, and whole grains, it plays a key role in maintaining healthy skin, aiding wound healing, supporting the nervous system, and helping to reduce stress.

Vitamin B5

Nicotinamide, also known as niacinamide, is a form of vitamin B3 that plays a key role in cellular metabolism. It supports the health of the skin, nervous system, and digestive system. Unlike nicotinic acid, another form of vitamin B3, nicotinamide does not cause skin flushing. It is commonly used to treat skin conditions such as acne and is being researched for its potential benefits in neurodegenerative diseases and cancer prevention. Naturally found in foods like meat, fish, and green vegetables, nicotinamide is also available as a supplement and is widely included in skincare products.

Nicotinamide

Holotranscobalamin (holoTC), also known as active vitamin B12, is the form of vitamin B12 bound to transcobalamin, a transport protein in the blood. It is the only form that can be absorbed by cells through receptor-mediated endocytosis, making it directly available for cellular functions. Measuring holoTC provides a more accurate indication of recent vitamin B12 status than total vitamin B12, as it reflects the fraction that is immediately available for use by the body.

Holotranscobalamin (B12)

25-hydroxy Vitamin D3 (25(OH)D3) is the primary circulating form of vitamin D in the human body and the most accurate marker for assessing vitamin D status. It is synthesized in the skin upon exposure to UVB radiation from sunlight and can also be obtained from dietary sources such as fatty fish, egg yolks, and fortified foods.

Once produced or ingested, vitamin D3 is converted in the liver to 25(OH)D3, which is the major storage form of vitamin D. This form is essential for maintaining calcium and phosphate balance, supporting bone health, and modulating immune, endocrine, and neuromuscular functions.

25-hydroxy Vitamin D3

25-hydroxy Vitamin D2 (25(OH)D2) is one of the two main forms of vitamin D measured in the blood, the other being 25-hydroxy Vitamin D3. While Vitamin D3 is typically produced in the skin through sunlight exposure and obtained from animal-based sources, Vitamin D2 comes from plant-based sources and supplements.

25(OH)D2 is converted in the liver from ergocalciferol (Vitamin D2) and indicates the body's intake of this form of the vitamin. It plays a role in calcium and phosphate metabolism, immune function, and overall bone health. Although Vitamin D2 is less potent and has a shorter half-life than Vitamin D3, both forms contribute to total vitamin D levels.

25-hydroxy Vitamin D2

The home test was straightforward with easy to follow instructions. The test result was detailed and clear in its presentation. Also had the opportunity to ask questions about the test result.

We looked at a lot of companies offering the same services but made the decision to go forward with get tested because the labs are based here in the USA. The process has been very straight forward.

There are other providers out there, I have tried 3. Gettested was the fastest and the customer service was the best. I even received my test on the day of purchase delivered by a motorbike courier.

Absolutely perfect, results came after few days and finally after a lots of times visited GP, we finally know why my son has eczema - he is allergy to carrot. Thanks a lot.

I found them to be professional and not too long a wait for results. Helpful with any after questions. Will be using them again if need be. I highly recommend them.

People who would benefit from testing their vitamin D levels include those with limited sun exposure, older adults, individuals with darker skin, those with conditions affecting nutrient absorption like celiac or Crohn&rsquo;s disease, obese individuals, and people taking medications that impact vitamin D metabolism.

Who would benefit from testing their vitamin D levels?

<ul>
 <li>Bone pain and muscle weakness</li>
 <li>Frequent infections or illness</li>
 <li>Fatigue and tiredness</li>
 <li>Bone fractures or weakness</li>
 <li>Mood changes, like depression</li>
 <li>Impaired wound healing</li>
 <li>Hair loss</li>
</ul>

What are symptoms of low vitamin D?

The best dietary sources of vitamin D include fatty fish like salmon, trout, and mackerel, which are among the richest natural sources. Fish liver oils, like cod liver oil, are also high in vitamin D. Small amounts are found in beef liver, cheese, and egg yolks. For those who prefer plant-based options, fortified foods are a good alternative; these include dairy and plant milk, orange juice, and certain cereals.

What foods are high in vitamin D?

Vitamin D3 (cholecalciferol) is generally considered more effective than vitamin D2 (ergocalciferol) because it is more potent, stays longer in the body, and is more efficiently utilized. However, the choice between D3 and D2 may depend on dietary preferences, as D3 is usually derived from animal sources and may not be suitable for vegans, while D2 is plant-based.
