I heard that NAD has a fast-acting effect, so I thought I'd take NAD on days when I'd be using a lot of energy, and NMN on other days... but it makes me nauseous. Sometimes it happens immediately, sometimes a little while later. I guess these kinds of supplements just don't suit everyone's body.

Super drug!
Verified Purchase
I take the quality and composition of what I need in combination with other drugs as prescribed by a doctor! Convenient packaging minus that there are only 30 capsules! If the capsule is too big and difficult to swallow, just open it and take it as a powder with enough water. , tastes sour a little like citric acid ) in general, it copes with its function perfectly! Satisfied!

I bought this because I heard it has good ingredients. It doesn't cause a niacin flush, and it's supposed to be good for energy metabolism. I've been taking a lot of different supplements, so I'm not sure how effective it is yet, but I've heard this ingredient is really good these days. The pill size is just right, too.

7 NAD (nicotinamide adenine dinucleotide) is a coenzyme essential for energy production, DNA repair, and cellular metabolism. It is used in the form of dietary supplements and injections to combat fatigue, improve brain function, support heart health, and slow the aging process. What is NAD+ used for? Energy and metabolism: NAD+ is involved in the conversion of nutrients into energy, which helps fight fatigue and improves endurance. DNA repair: This molecule is necessary for repairing damaged DNA and protecting cells, which slows aging. Brain health: Helps improve cognitive function, memory, and concentration by protecting nerve cells from damage. Cardiovascular: May improve circulation, restore vascular elasticity, and support heart function. Anti-aging: Activates proteins (sirtuins), which play an important role in maintaining cellular health and slowing aging. Other areas: NAD+ therapy is also used in rehabilitation after illness and stress, as well as in programs to combat drug addiction.

The best NAD+ formula
Verified Purchase
I have been using it for 3 weeks on the recommendation of a nutritionist and it has shown the best results I have ever had from NAD+! I use it in the morning with breakfast, from 7-9 am, when it is best absorbed, and 5 days a week. I do not use it on the weekend so that the body does not get used to it and there is a better result! The capsules are small, there are no problems with swallowing. The skin is radiant, healthy. I highly recommend it!

The capsules are a convenient size, easy to swallow and do not cause any problems. The packaging is compact and reliable - easy to store and take with you. Good quality. As a result of taking it, there is a feeling of vigor and inner freshness: I notice a slight increase in energy and clarity, especially on days with a tense rhythm. The opinions of other users confirm that the capsules really inspire

good
Verified Purchase
The quality is good, the quantity and ingredients are written on the page. The benefits of NAD+ differ from one company to another, but the benefits of this supplement are many. It gives energy and beauty to the skin. As for me, every time I take a different company, and thank God, all the companies have original products. I strongly recommend using it, and it is necessary for girls to continue in order to benefit, because the supplement definitely needs time, but you will love it, God willing.

The effect of the product is noticeable - it became easier to get up in the morning, the overall tone increased. Nice packaging, the composition is described in detail. The dosage is easy to use, the taste does not cause disgust. It is good that the ingredients are of high quality, without unnecessary flavors. Excellent price for such quality.

A decent energy booster. Good ingredients, but not enough to evaluate its effects after a week.
