“So, out of these discoveries came the idea that maybe we should replenish the decreasing levels of NAD, and so this has yielded some discoveries, such as nicotinamide riboside, nicotinamide mononucleotide, which are now being taken by a lot of people with the hope that they will, you know, correct some of these problems.”
Main Takeaways:
- Decreasing NAD levels with age has led to the development of supplements like nicotinamide riboside and nicotinamide mononucleotide.
- These supplements are intended to replenish NAD levels in the body.
- The hope is that by restoring NAD levels, some age-related metabolic issues can be mitigated.

“Nicotinamide riboside? Yes, for example, the paper we’ve published was focused on the age-associated or noise-induced loss of hearing. So, if you actually subject mice or humans to very acute noise, they have a dose-dependent loss of hearing. You can protect the mice completely from this effect by supplementing with NAD.”
Main Takeaways:
- Nicotinamide riboside is a form of NAD used in supplements.
- Supplementing with NAD can protect against noise-induced hearing loss in mice.

“NAD stands for nicotinamide, which is vitamin B3, and adenine dinucleotide.”
Main Takeaways:
- NAD is crucial for cellular energy transfer.
- It is composed of nicotinamide (vitamin B3) and adenine dinucleotide.
- NAD is essential for life, supporting various biochemical reactions.
Notes: Explanation of what NAD stands for
Tone: Informative

“high do vitamin B3 is in boy 3 it's also called in its various forms either nicotinic acid or nicotinamide”
Main Takeaways:
- High doses of Vitamin B3, also known as nicotinic acid or nicotinamide, are being studied for their potential benefits in glaucoma.
- Vitamin B3 is involved in the NAD synthesis pathway, crucial for cellular metabolism and oxidative stress regulation.

“There are really kind of four NAD precursors that people think about oral or orally available NAD precursors there's nicotenomid monucleotide NMN and nicotenomid ribocide NR those are the two that get the most attention.”
Main Takeaways:
- Four main orally available NAD precursors are commonly discussed: NMN, NR, nicotinamide, and niacin.
- NMN and NR are more expensive and popular in the influencer community.
Notes: Discussion on the types and popularity of NAD precursors.
Tone: Informative
Relevance: 4/5
“NMN and NR cost about 100 times more than nicotinamide and niacin so if you really think you want to take NAD precursors sure you're welcome to buy the expensive stuff that gets broken down to the cheap stuff in your gut but there's no real good reason to do that.”
Main Takeaways:
- NMN and NR are significantly more expensive than nicotinamide and niacin.
- All these precursors ultimately have similar effects on NAD levels.
Notes: Economic consideration in choosing NAD precursors.

“I take it first thing in the morning, morning um and what dose one and a half gram 1500 milligrams so by the way if you translate you know the the doses that they give mice in the studies where they're testing the efficacy um are typically on the order of 500 to 1,000 milligrams per kilogram.”
Main Takeaways:
- The speaker takes 1500 milligrams of a supplement in the morning.
- Mice in studies typically receive 500 to 1000 milligrams per kilogram for efficacy testing.
Notes: Discussing dosage comparisons between humans and mice in studies.
Tone: Informative

“NR can cross the cell membrane directly very easily there's no obstacle to NR getting into cells okay and NMN cannot because of that extra phosphate group.”
Main Takeaways:
- NR can easily cross the cell membrane, facilitating its entry into cells.
- NMN has an extra phosphate group which hinders its ability to enter cells as effectively as NR.

“Sublingual NMN is also a bit of a laxative so there all these and I say that you know somewhat chuckling but you know some people say it makes them feel better well is that because you're you know evacuating your bowels a few minutes or hours later and then you feel less bloated and you have more energy.”
Main Takeaways:
- Sublingual NMN has a laxative effect, which might contribute to feelings of increased energy and reduced bloating.
- The perceived benefits of NMN might be partially due to its effects on bowel movements.
