Nicotinamide

The product is available in capsule or tablet form for easy oral administration, free of genetically modified organisms (GMO-free), gluten, soy, dairy, or other major allergens. 

For example, Nicotinamide NMN Jarrow Formulas from Secom has a concentration of 125 mg of nicotinamide mononucleotide per tablet and is recognized for the purity and pharmaceutical quality of its ingredients.

There are also formulas that contain nicotinamide riboside, a precursor to NMN, such as those from Doctor Life or NewLife+.

NMN (nicotinamide mononucleotide) supports cellular energy production by increasing levels of NAD⁺, a coenzyme essential for mitochondrial function. Through this mechanism, it can help slow down the aging process, improve cognitive function, insulin sensitivity, and physical performance. 

Nicotinamide mononucleotide is particularly indicated for:

• supporting mitochondrial function and ATP production;
• delaying cellular aging processes;
• improving cognitive ability and reducing fatigue;
• protecting DNA from oxidative damage;
• maintaining good muscle function in the elderly;
• improving insulin sensitivity in metabolic syndrome;
• reducing the risk of neurodegenerative and cardiovascular diseases.

In general, the usual recommended dose is 1-2 capsules per day, taken between meals, as directed by your doctor. 

This dose is considered safe and effective in maintaining optimal NAD⁺ levels, with no significant adverse effects.

NMN administration is contraindicated in the following situations:

• children under 18 years of age;
• pregnant or breastfeeding women;
• people who are allergic to any of the product's ingredients;

People with severe chronic conditions should seek medical advice before taking this dietary supplement.

Nicotinamide is a promising supplement, but it should not be used as a substitute for medical treatment, only as an adjunct. 

Also, the effects are gradual and take time to develop, requiring daily administration for a minimum of 8-12 weeks for visible results.

According to current clinical studies, nicotinamide is well tolerated, even in higher doses. In rare cases, the following may occur:

• mild gastrointestinal disorders (bloating, nausea);
• headache or agitation

No serious adverse reactions have been reported in short-term studies, but long-term safety requires further investigation.

Nicotinamide may interact with some medications such as anticoagulants or antihypertensives. Also, combining it with other stimulant supplements (e.g., caffeine, guarana) may increase agitation or insomnia.

No negative interactions are known, but it is recommended to take it between meals for optimal absorption.

There is insufficient data on the effects of accidental overdose. However, very high doses may cause digestive disorders or severe insomnia.

In case of accidental ingestion of a large dose, it is recommended to contact a doctor immediately and monitor symptoms for 24 hours.

The product should be stored in its original packaging, tightly closed, at temperatures below 25°C, away from light, excessive heat, and humidity, and out of the reach of children. Use after the expiration date printed on the packaging is not recommended.
