In einem Buch über Mikronährstoffe entdeckt

Ich lese gerade mehr über Mikronährstoffe und bin dabei auf einen Inhaltsstoff gestoßen, den ich vorher kaum beachtet hatte. Der Bezug zu Energiehaushalt und Müdigkeit war für mich letztlich interessanter als eine lange Zutatenliste.

Fairvital Vitamin B-3 500mg provides 500 mg of niacin per tablet in the form of nicotinamide. At 3125 % NRV, niacin is included at a high strength.

Vitamin B3 for energy and the nervous system: Niacin contributes to normal energy-yielding metabolism and to the normal functioning of the nervous system. It also contributes to the maintenance of normal skin.

Nicotinamide instead of nicotinic acid: The vitamin B3 it contains is present as nicotinamide, also known as niacinamide. Fairvital points out that, unlike nicotinic acid, this form does not usually cause a classic niacin flush.

One tablet a day: The entire daily serving of 500 mg is contained in just one tablet. With 100 tablets, one pack offers a 100-day supply.

Fairvital quality: The tablets are vegan and free from gluten, lactose and fructose. The product is manufactured in Germany to high quality and hygiene standards. Fairvital Vitamin B-3 500mg gives you high-strength niacin as nicotinamide at 3125 % NRV in a straightforward one-tablet daily serving.

We therefore recommend that you inform yourself independently on specialist portals on the internet or in naturopathic literature before placing an order.

Fairvital Vitamin B-3 500mg is ideal for anyone who prefers a high-strength single vitamin B3 product. Niacin contributes to normal energy-yielding metabolism and to normal functioning of the nervous system. It also contributes to the maintenance of normal skin.

Vitamin B3 is also known as niacin and comprises different related forms of the vitamin. It is found in meat, fish, peanuts and mushrooms, among other foods. The body can also produce small amounts of niacin from the amino acid tryptophan.

Particularly important are the coenzymes NAD and NADP, in which niacin occurs as a building block. They transfer electrons in numerous metabolic reactions and are therefore closely linked to energy production. Niacin also contributes to the normal functioning of the nervous system and to the maintenance of normal mucous membranes.

Vitamins are absorbed and stored differently depending on their solubility. With water-soluble vitamins, regular intake from food is important; fat-soluble vitamins are absorbed together with dietary fats. The exact form of a vitamin compound determines which conversion steps take place after absorption.

The body does not use vitamins as classic sources of calories. Instead, many of them are needed as cofactors for enzymatic reactions or perform specific tasks in tissues. The various forms of vitamins can differ considerably in their chemical properties.

In the Fairvital product Vitamin B-3 500mg, the formula shows the form and amount of the ingredients used. According to the list of ingredients, these include nicotinamide. The composition table states 500 mg of vitamin B3 per tablet. The pack contains 100 tablets.
