oside + Resveratrol (900mg). It arrived on time and well-packaged, which set a great first impression. The capsules are easy to take, and I love that they support NAD+ levels, healthy aging, and skin health. This brand’s confidence in their product is the best part of all. Happiness guaranteed!

My skin is GLOWING. Wrinkles are diminishing after 3 weeks of use. Will continue to purchase.

I have been using very expensive supplements for 6 years that I love and have restored me tremendously, just to find out that the ingredients is basically what this wonderful NAD is made off , of course I tried this NAD booster and works as good as the expensive one , totally recommend

Why is my bottle not sealed? The bottle is damaged...looks like its been melted. The item looks sketchy. Has this been tampered with? I'm concerned about using this product. The box was "perfectly fine" which makes me wonder how the bottleis NOT OK.

Exelente es mi 4 vez y ahora tengo a toda mis amigas y familia tomándolas son muy buenas yo las recomiendo 100% y si hay cambios buenos

Personally the quality of the supplement had change as well as the packaging. The first I made a purchase the pills came white then the second purchase they were yellow. I email customer service and they replied quickly and sent a replacement but I was not confident taking them due to the color.

Be aware I bought them the capsules are not all the way full, this is a ripoff and for the high price is not worth spending your money.. I counted only five where just about full.. save you money

Me encanta el producto he visto buenos resultados lo recomiendo 100%

I’m not sure if these actually work? But my order arrived damaged,majority of the capsules are broken and appear to have mold? So I’m afraid to even take them. They arrived in a bag,not a bottle.

This is my second bottle! This has strengthened my nails and have made them grow so quickly! I’ve never even bothered to paint my nails since they would look so chewed up and chipped. After the first 30 days I could feel my nails harden! Now I have nails to paint, that survive my work environment💅

Since starting Cata-Kor NAD Advanced 500mg, I feel like I've turned back the clock! My energy levels are through the roof, I'm laser-focused at work, and even my skin looks noticeably brighter. It's like a revitalizing boost from the inside out. Highly recommend!

Recommend! I was leery due to having tried other brands in the past. I'm so glad I took another chance! My skin looks more even-toned & I'm also noticing fewer fine lines under my eyes. Keep in mind I've only been using NAD by Reus Research for about 1 month. The order turn-around was quick as well!

Not convinced this isn’t all a scam. My bottle looked like the “legit” Reus Research bottle & had a QR code on the lid that went to a site called reusgifts.com with an expired promotion. The bottle had a contact email help@tryreus.com, but that’s not on the website. I threw it away & wont buy again

I try not to run out of this, easy to swallow and I feel great. You won't see changes overnight, have to take consistently if you want those results. Sometimes you'll get it in a pouch and not a bottle, I got it in the bottle once, ither times it was a pouch so I keep my bottle and put them it it.

This product works. At first I was skeptical about it but after 3 weeks of taking it I started feeling and seeing the results, the transformation from the old you to the new you is amazing. I recommend this product but make sure to get the real one that TokTok recommends. Happy youthful to ALL.

Me encantan realmente veo la diferencia en mi piel tres meses ya de tomarlas gracias 😊 con mucha energia me llego muy rapido 🙂

Estoy feliz de que el producto sea original pues antes había comprado las pastillas a otro proveedor y eran falsas, estas son originales

This is my first time trying this product and I can see the difference in my skin. I am not purchasing this product the second time around because I feel like a really brought life into my body and I felt amazing and not quite sure on the energy part, but as far as skin replenish, yes!!!!

The box and container were both crushed and there were some that were damaged and I had to throw away. I can tell a difference in how I look and feel after taking them.

The box, bottle and pills are all different from the first box of reuss research, i don't know if they are authentic or not, box. And bottle are slightly different sizes, the original pills are a little yellow but the knockoffs and the recent bottle pills are white and not slightly yellow, IDK.
