Nicotinamide, also known as niacinamide, is a form of vitamin B3. It's essential for cellular metabolism and is involved in skin, nervous system, and digestive health. Unlike nicotinic acid, another form of vitamin B3, nicotinamide doesn't cause skin flushing. It's used in treating skin conditions like acne and is being studied for potential benefits in neurodegenerative diseases and cancer prevention. Found in foods like meat, fish, and green vegetables, nicotinamide is also available as a supplement and is commonly used in skincare products....

Nicotinic acid, also known as niacin or vitamin B3, is essential for converting food into energy and maintaining healthy skin, nerves, and digestion. It's found in foods like meat, fish, and grains and can be synthesized from the amino acid tryptophan. Deficiency of nicotinic acid leads to pellagra, characterized by diarrhea, dermatitis, and dementia....

Vitamin A also supports growth and reproduction....

Vitamin B12, or cobalamin, is a water-soluble vitamin essential for red blood cell formation, nervous system health, and energy metabolism.

It's found in foods like vegetable oils, nuts, seeds, and green leafy vegetables. While deficiency is rare, it can lead to neurological issues....

Vitamin E

Holotranscobalamin (holoTC), also known as active vitamin B12, is a form of vitamin B12 that is bound to transcobalamin, a transport protein in the blood. This combination is biologically significant because it is the only form of vitamin B12 that can be taken up by cells via receptor-mediated endocytosis, making it readily available for cellular processes. Measurement of holotranscobalamin levels is considered a more direct marker of the recent vitamin B12 status in the body than the total vitamin B12 test, as it represents the fraction of vitamin B12 that is actually available for cellular uptake and immediate use....




Holotranscobalamin

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 UK. 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.

Testing for vitamin B12 levels is especially important for older adults who may have absorption issues, vegetarians and vegans who don&rsquo;t consume animal products, people with gastrointestinal disorders like Crohn&rsquo;s or celiac disease, individuals who have undergone gastric bypass surgery, those diagnosed with pernicious anemia, and people on medications like metformin or acid-reducers that can affect B12 absorption.

Who would benefit from testing their vitamin B12 levels?

Symptoms of vitamin B12 deficiency can be varied and may develop gradually, including:
<ul>
 <li>Fatigue and Weakness</li>
 <li>Anemia</li>
 <li>Numbness and Tingling</li>
 <li>Balance and Coordination Problems</li>
 <li>Memory and Cognitive Difficulties</li>
 <li>Mood Changes</li>
 <li>Glossitis and Mouth Ulcers</li>
</ul>
If left untreated, B12 deficiency can lead to severe neurological damage and blood diseases.

What are symptoms of vitamin B12 deficiency?

The best sources of vitamin B12 are found in animal products, including meats like liver and beef, poultry, fish such as sardines and salmon, shellfish, dairy products, and eggs. For vegetarians and vegans, fortified foods like certain cereals and plant-based milks, as well as supplements, are reliable sources to maintain adequate B12 levels.

What are the best dietary sources of vitamin B12?

Vitamin B12 supplementation is beneficial for preventing anemia by aiding red blood cell formation, supporting nerve health, boosting energy levels, and improving mood and cognitive function. It&rsquo;s also important for heart health by lowering homocysteine levels, a risk factor for heart disease. This is particularly crucial for older adults, vegetarians, vegans, and those with absorption issues, ensuring adequate intake of this essential nutrient. Consulting a healthcare provider before starting supplements is recommended.
