Niacina de liberación prolongada Rugby 1000 mg, 100 comprimidos

What is vitamin B3 (niacin)?

Niacin, also known as vitamin B3, is an essential nutrient that the body needs to convert food into energy. It is part of the B vitamin complex and plays a key role in numerous bodily functions. Being water-soluble, the body does not store it, so it is necessary to obtain it regularly through diet or supplements.

Vitamin B3 is naturally found in foods such as lean meats, fish, legumes, and whole grains. However, some people may have difficulty reaching recommended levels, especially those with restrictive diets or certain health conditions. In such cases, a supplement like this can help meet daily needs.

Benefits backed by the EFSA

The European Food Safety Authority (EFSA) has approved the following health claims for niacin:

• Normal energy metabolism: Niacin contributes to normal energy metabolism, helping to transform nutrients into usable energy for cells.
• Nervous system: It contributes to the normal functioning of the nervous system, supporting the transmission of nerve impulses.
• Psychological function: Niacin contributes to normal psychological function, including cognitive processes such as concentration and memory.
• Skin and mucous membranes: It helps maintain the skin and mucous membranes in normal conditions, promoting their integrity.
• Reduction of tiredness: It contributes to the reduction of tiredness and fatigue, supporting daily energy levels.

These claims are authorized by European Union legislation and are based on solid scientific evidence. It is important to remember that food supplements should not be used as a substitute for a balanced and varied diet.

Forms of niacin: niacin vs. niacinamide

There are two main forms of vitamin B3 in supplements: niacin (nicotinic acid) and niacinamide (nicotinamide). Both are effective, but they have key differences.

Niacin is known for causing a flushing effect on the skin when taken in high doses. This effect is temporary and harmless, but it can be uncomfortable. Niacinamide, on the other hand, does not cause this flushing.

This product contains niacin in its nicotinic acid form, but with an extended-release technology that releases the ingredient gradually, which helps minimize the appearance of the flush. It is an ideal option for those who want to benefit from niacin with greater comfort.

How does extended release work?

The controlled-release formula of this supplement is designed for niacin to dissolve progressively in the digestive tract. This allows for more constant absorption and reduces peaks in blood levels, which translates into a lower probability of experiencing the characteristic facial flushing.

In addition, this delivery system can promote sustained support for energy metabolism throughout the day, avoiding ups and downs. Each tablet contains 1000 mg of niacin, a dose that is within the range used in clinical studies and is usually recommended for adults.

Recommended dosage and method of use

The indicated dose for adults is 1 tablet daily, preferably with a meal to facilitate digestion. This amount should not be exceeded without prior consultation with a doctor or health professional. This product is not intended for children or pregnant or breastfeeding women without medical supervision.

It is important to note that niacin needs may vary depending on age, sex, and health status. Therefore, it is always advisable to follow the instructions on the package or those of a health professional.

Possible side effects and precautions

Niacin can cause a temporary flushing accompanied by a sensation of warmth, itching, or tingling, especially at the beginning of treatment or if taken on an empty stomach. The extended-release formula helps reduce this effect, but does not eliminate it completely. If the flushing persists or is uncomfortable, the dose can be divided or taken with food.

In high doses, niacin can also cause gastrointestinal discomfort, headache, or elevated liver enzymes. People with liver problems, peptic ulcers, diabetes, or gout should consult their doctor before taking this supplement. It can also interact with certain medications, such as antihypertensives or anticoagulants.

Keep the product out of the reach of children, in a cool and dry place. It should not be used as a substitute for a varied diet. If in doubt, consult a healthcare professional.
