Nothing
[This review was collected as part of a promotion.] These did absolutely nothing for me. I’m not even sure what they were supposed to accomplish, but I might as well have took candy gummies for all these did.

Good
[This review was collected as part of a promotion.] I really enjoyed the month of taking a supplement. Nicotinamide can increase NAD, which can give you more energy, keep you looking youthful, improve your skin. The capsules are easy to take, and I haven’t noticed any upset stomach or side effects from it. Overall, I like a science behind this product it’s just not a long enough supply to notice long-term changes with it.

Decent supplement that has potential
[This review was collected as part of a promotion.] This product to me seems pretty decent. I haven’t noticed much of a difference in my cognition or my skin in terms of the anti-aging properties it should have, but that might be because I’m not middle aged or older. The pills themselves are a little big for anyone that is sensitive to swallowing pills but pretty standard size for most supplements. I think if you are looking for a supplement for NAD+ then these will be pretty good.

A little pep
[This review was collected as part of a promotion.] I like the packaging. It looks like little cells on the side of the logo. The supplement facts are pretty straightforward. Really not a lot of ingredients. Pills are easy to swallow. It also has an expiration date of 2028, which is quite a long shelf life The product itself was good I had more energy. I felt like I slept better as well and had better digestive health which for me is very important. Overall I would continue to use this product over others

A bit more energy mid day!
[This review was collected as part of a promotion.] Easily digestible, the texture make them easy to swallow also. I didn’t notice a huge difference but did feel a bit more energy mid day than usual. I just don’t know if the value is there for me without a noticeable difference, but anyone who knows the benefits of the ingredients it seems like it would be worth the money for them!

Effects will hopefully show up over time
[This review was collected as part of a promotion.] I've been taking NR from different brands on and off for years. This was my first time trying a product from Youtheory. I was surprised that the capsules are yellow when all my previous experiences have been with white capsules or tablets. This could be because of the additional quercetin. I appreciate that this is a higher dosage of NR then other forms I've tried. The serving size is two capsules which sometimes I've taken at the same time and sometimes I've split up. This isn't the kind of supplement where you feel the effects immediately, but rather you'll see results as you age gracefully over time. I didn't really observe the effects on a day-to-day basis, which is probably a good thing. (No anxiety, no digestive distress, etc.) There were a few times when I took two capsules in the morning and thought maybe I had elevated energy that day, but it could have been a placebo because it's not a regular occurrence. Overall, I'm happy with the product. The standard size capsules are easy to swallow, and they have no taste or smell.

Great Supplement to help you stay active
[This review was collected as part of a promotion.] First time trying a NR supplement but have to say I was impressed. Pill is easy to swallow and didn’t cause any stomach discomfort whether taken on an empty stomach or with food. I will say before receiving this free sample I had caught a cold from my 2 yr old nephew; right before I had a wedding and hiking trip in RMNP over Labor Day weekend. I will say I got over my cold symptoms a full 24-48 hrs sooner than my sister + BIL. This allowed me to hike 14 miles at RMNP which I wasn’t sure I was going to be able to do at elevation with the cold symptoms. I do attribute a big part of being able to power thru on taking this Youtheory supplement. I plan on continuing use as it’s affordable, has no side effects, and helps me continue to have the energy and do the outdoor activities I love!

I’ve been taking Youtheory NR
[This review was collected as part of a promotion.] I’ve been taking Youtheory NR (nicotinamide riboside) for a few weeks, taking it in the morning, usually with my first part of the day and no later than late morning. It has been easy to incorporate into my normal routine, and I haven’t had any issues remembering to take it. The biggest thing I’ve noticed so far is a subtle boost in energy after taking it. It isn’t a dramatic or stimulant-like effect, but I do feel like I notice a little more energy throughout the day. I haven’t noticed any other significant changes yet, but I also think it’s too early to make a meaningful judgment about things like cellular health, recovery, or healthy aging. One thing I particularly appreciate is the ease of taking the capsules. They are quite large, but the coating makes them surprisingly easy to swallow. I’ve historically had trouble swallowing larger pills, so that was something I was initially concerned about, but it hasn’t been an issue with these. Overall, I would consider continuing to take Youtheory NR, particularly if I continue to notice the energy benefit. At this point, the biggest factor for me would be the cost and whether the perceived benefit is worth continuing as part of my daily supplement routine. I’d want to use it for a longer period before making stronger claims about its longer-term benefits. I received this product for free in exchange for my honest review.

No Noticeable Difference
[This review was collected as part of a promotion.] Disclosure: I received this product for free in exchange for my honest review. I used the product consistently for two weeks as part of my morning routine. I took it in the morning each day, making it easy to incorporate into my existing routine without needing to make any significant changes to my schedule. One thing I liked about the product was that it was nearly tasteless and did not leave an unpleasant aftertaste. I was generally able to swallow it easily. However, I did experience a sensation of the pill feeling like it was getting stuck in my throat, which was the main issue I noticed with taking it. Other than that, I had no problems using the product and experienced no side effects during the two weeks I tested it. From a convenience standpoint, it was straightforward to use and easy to add to my daily routine. I didn't find the format particularly complicated or time-consuming. The lack of a strong taste or lingering aftertaste was also a positive. As far as noticeable results, I did not observe any significant changes or benefits during the two-week testing period. I think the limited testing time is important to consider when evaluating my experience. Some products may require longer, consistent use before any noticeable effects occur, so I wouldn't necessarily conclude that longer-term use would have the same results. Based solely on my two weeks of use, though, I couldn't say that I noticed a difference. For someone considering this product, I think it may be worth considering if you're looking for something that is easy to incorporate into a morning routine and doesn't have a strong taste or aftertaste. My experience was generally uncomplicated, although the occasional sensation of the pill getting stuck in my throat is worth mentioning. I don't have enough experience with similar products to make a meaningful comparison or say that this product is better or worse than other options. Overall, my experience over two weeks was positive in terms of convenience and lack of side effects, but I did not personally notice any specific benefits during the time I tested it.

Youtheory Nicotinamide Riboside (NR)
[This review was collected as part of a promotion.] Daily Protocol & Routine Integration As a Clinical Exercise Physiologist and Kinesiology Professor logging heavy weekly trail running mileage and managing an active academic and teaching schedule, cellular recovery is a non-negotiable priority. I incorporated Youtheory Nicotinamide Riboside (NR) into my morning routine every day for 30 consecutive days. I took the capsule serving each morning with breakfast and a glass of water alongside my standard post-workout hydration setup. Ease of Use, Size & Format The capsule format is straightforward and highly convenient. The capsules are standard size (easy to swallow without any lingering taste or aftertaste) and caused zero gastrointestinal distress, even when taken before high-output movement or early-morning training sessions. The daily dose makes compliance effortless compared to multicoat protocols or multi-pill serving sizes common in this category. Noticeable Benefits & Observations After about two weeks of consistent daily use, I noted a steady, subtle improvement in overall daily stamina and recovery between high-intensity training days. Rather than a harsh caffeine-like spike, the benefit felt like sustained cellular energy—less afternoon fatigue after continuous hours of teaching and faster bouncing back from back-to-back training sessions. Formulation & Category Comparison What sets this formula apart from standalone NR or NMN supplements on the market is the synergistic addition of Quercetin. From a physiological standpoint, pairing an NAD+ precursor like NR with a flavonoid that helps inhibit NAD+-degrading enzymes provides a much more complete approach to cellular resilience and healthy aging than single-ingredient alternatives. Best Suited For This product is ideal for endurance athletes, active outdoor enthusiasts, mid-career professionals, and health-conscious adults seeking to proactively support mitochondrial health, baseline cellular energy, and systemic recovery. Disclosure: I received this product for free in exchange for my honest review.

Easy add to my daily routine
[This review was collected as part of a promotion.] Easy add to my daily supplements. They are simple to take and fit in well with the other vitamins/supplements I already take to optimize my health and wellbeing. I received them on 8/27 (9/14 today), so for only about 2. 5 weeks of use, it’s difficult to observe a definitive difference. That being said, I appreciate the ingredients utilized in this supplement, and am looking forward to comparing results upon completion of this round. This product would be a good fit for those looking to optimize their health with dairy free, soy free, and non-gluten supplements. I received this product for free in exchange for my honest review.

Great Addition to Fighting Aging from Within
[This review was collected as part of a promotion.] Youtheory’s Nicotinamide Riboside supplement is a NAD+ booster for cellular renewal and healthy aging support. These all vegetarian capsules fit easily into my daily health routine. NAD is an important part of life and as you age, those levels decline. These supplements help to restore levels and promote healthy aging from the inside out. The capsules are esay to take, just two a day. I did notice more energy while taking this product! I do recommend Youtheory’s Nicotinamide Riboside for those individuals looking to increase their NAD levels during aging!

Vegetarian capsules for physical energy.
[This review was collected as part of a promotion.] I'm taking the capsules I received from Influenster to give my honest opinion. Although I find them quite large, I'm managing to swallow them with a little water. Apparently, it's doing me good, giving me a bit more energy. I'll continue taking them and hope they bring me great benefits.
