Vitamin B3
Vitamin B3 (Niacin) is an essential nutrient that helps convert food into energy and supports the health of the skin, nervous system, and digestive system. It is found in foods such as meat, fish, poultry, and whole grains. Niacin also helps maintain healthy cholesterol levels and overall metabolic function. A deficiency may cause fatigue, skin issues, and cognitive problems, and supplementation may be necessary in certain medical conditions.
Description
Testing for vitamin B3 levels can benefit individuals experiencing symptoms of deficiency, such as skin rashes, fatigue, or cognitive difficulties. It’s also helpful for those with digestive disorders affecting nutrient absorption, individuals with alcohol dependence, and those on long-term medications that may interfere with vitamin B3 absorption or metabolism.
- Skin rashes, especially in areas exposed to sunlight
- Fatigue or weakness
- Headaches
- Digestive issues
- Memory problems, confusion
- Mouth sores, swollen bright red tongue
- Depression or mood swings
Foods high in vitamin B3, also known as niacin, include poultry like chicken and turkey, fish such as tuna and salmon, and red meat. Whole grains and fortified cereals also contain significant amounts of niacin. For plant-based diets, legumes, nuts, particularly peanuts, and seeds are good sources. Additionally, mushrooms and green vegetables like peas and avocado provide vitamin B3.
Vitamin B3, or niacin, supplementation is beneficial for improving cholesterol levels, supporting skin health, and boosting brain function. It’s effective in reducing the risk of heart disease and may aid in managing blood sugar levels in diabetes.

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.
