Kal Niacina 25 mg, 200 Comprimidos Sabor Fresa

What is Vitamin B3 (Niacin)?

Vitamin B3, also known as niacin, is a water-soluble vitamin essential for the proper functioning of the body. It is part of the B vitamin complex and plays a key role in converting food into energy. Niacin is naturally found in foods such as chicken, tuna, chickpeas, and nuts, but sometimes additional intake through supplements may be necessary to meet daily needs.

Kal Niacin 25 mg tablets offer a convenient and pleasant way to incorporate this vitamin into your daily routine, with a delicious natural strawberry flavor that makes it easy to consume. Each microtablet provides 25 mg of niacin, an adequate dose to support various bodily functions.

Benefits Backed by EFSA

The European Food Safety Authority (EFSA) has approved several health claims for niacin. Among them, it is highlighted that niacin contributes to normal energy metabolism, helping to convert nutrients into usable energy for cells. It also supports the normal functioning of the nervous system, which is fundamental for maintaining concentration and mental balance.

• Niacin contributes to normal energy metabolism.
• Niacin contributes to the normal functioning of the nervous system.
• Niacin contributes to normal psychological function.
• Niacin contributes to the maintenance of normal skin and mucous membranes.
• Niacin contributes to the reduction of tiredness and fatigue.

These claims are scientifically supported and are the only ones allowed in the European Union for this nutrient. It is important to note that supplements should not be used as a substitute for a balanced diet.

Forms of Niacin: Niacin vs. Niacinamide

Niacin can be present in two main forms: nicotinic acid (niacin) and nicotinamide (niacinamide). Although both are forms of vitamin B3 and share many functions, they have important differences. Niacin (nicotinic acid) is known to cause a flushing or itching effect on the skin, known as "flush," especially at high doses. This effect is harmless and usually disappears within a few minutes. Niacinamide, on the other hand, does not produce this effect and is often used in cosmetic products.

Kal Niacin 25 mg contains nicotinic acid, so it is possible to experience a slight flush. If you are sensitive to this effect, you can opt for flush-free forms such as niacinamide. However, niacin in its nicotinic acid form is the most studied for certain metabolic benefits.

Recommended Dosage

The recommended daily dose of niacin for adults in the European Union is 16 mg niacin equivalents per day. Each Kal tablet provides 25 mg, slightly exceeding the reference intake, but within the established safe limits (the tolerable upper limit is 35 mg per day for niacin in the form of nicotinic acid). It is recommended to take one tablet per day, preferably with meals for better absorption.

It is important not to exceed the recommended dose without consulting a healthcare professional. Very high doses can cause side effects such as the aforementioned flush or gastrointestinal discomfort.

Possible Side Effects

The most common side effect of niacin in the form of nicotinic acid is skin flushing or "flush," which is characterized by a sensation of warmth and itching on the skin, especially on the face and neck. This effect is temporary and can be minimized by taking the supplement with food or by gradually increasing the dose. Occasionally, mild stomach discomfort may occur.

At high doses (above 50 mg per day), niacin can cause more serious effects such as liver problems or elevated uric acid. Therefore, it is essential to respect the indicated doses and consult a doctor before taking this supplement if you are pregnant, breastfeeding, or if you suffer from any liver or kidney disease or gout.

Who Should Take Niacin Supplements?

Niacin supplements are indicated for people who wish to ensure an adequate intake of vitamin B3, especially those with restrictive, vegan, or vegetarian diets, as niacin is mainly found in animal products. They can also be beneficial for people who experience frequent fatigue, skin problems such as dryness or flaking, or who seek to support their cognitive function.

If you experience symptoms of niacin deficiency, such as dermatitis, diarrhea, or confusion (known as pellagra), it is important to see a doctor. Supplements should not replace professional medical advice or a varied and balanced diet.
