“It activates the sirtuins and the sirtuins are these defensive enzymes that, like the Pentagon, send out the troops.”
Main Takeaways:
- NAD activates sirtuins, which are enzymes involved in cellular defense.
- Sirtuins play a crucial role in cellular response to stress and aging.

“a lot of the press is oriented around this, the sexiness of things like rapamycin and Metformin and sirtuins and the like, which is very different than the kind of longevity science that you're interested in and focused on.”
Main Takeaways:
- Rapamycin, Metformin, and sirtuins are often highlighted in media discussions about longevity.
- These substances are associated with the more glamorous side of longevity research.
- The speaker contrasts these substances with other aspects of longevity science that may be less publicized but are of interest.

“well there are three main longevity mechanisms that we know of, they have certain names one's called sirtuins there's seven of those genes in our body and we've been working on them for 25 years another one's called mtor the other one's called ampk”
Main Takeaways:
- Three main longevity mechanisms are identified: sirtuins, mTOR, and AMPK.
- These mechanisms are activated by dietary practices like caloric restriction.

“They called 'sirtuins' and there are five of these genes in yeast and seven in our bodies. And they respond to low energy. They're respond to other stresses as well, such as high heat, low amino acids, high salt.”
Main Takeaways:
- Sirtuins are genes that respond to various stressors including low energy, high heat, and nutrient scarcity.
- There are different numbers of sirtuin genes in yeast and humans.

“What we know from studies of mTOR and AMPK, sirtuins is, tells our cells that times are tough. This triggers this metabolic shift into a different form of energy, and all of that, not all of that, but much of that we know from animal studies that we mentioned before.”
Main Takeaways:
- mTOR, AMPK, and sirtuins are involved in signaling metabolic shifts in response to environmental stressors.
- Much of the research on these pathways comes from animal studies.

“the other is to be hungry either a couple of times a week or every day you know skip a meal or two and then your body will turn on these sirtuins make more of that fuel nad for the enzymes”
Main Takeaways:
- Intermittent fasting or meal skipping can activate sirtuins, enzymes linked to longevity.
- This dietary practice increases NAD levels, fueling beneficial enzymes.

“So what you want to do is so naturally boost the activity of these sirtuins. They are genes, but they also make proteins. That's what genes typically make or encode. And then those proteins take care of the body in many different ways as we've discussed.”
Main Takeaways:
- Sirtuins are genes that produce proteins involved in various bodily functions.
- Boosting sirtuin activity can be beneficial for health.

“Well, the first activator of the sirtuins that we discovered that acts on the enzyme to make it do a better job of cleaning up the body and protecting resveratrol”
Main Takeaways:
- Resveratrol is identified as an activator of sirtuins, enzymes involved in cellular health.
- Sirtuins play a role in cleaning up the body and protecting it from damage.
Notes: Speaker discussing the discovery and function of resveratrol in activating sirtuins.
Tone: Informative

“And you can think of it as the accelerator pedal on a car. It revs it up, but there's something else that the sirtuins need to work and that's NAD and is a really small molecule, little chemical in the body that we need for life.”
Main Takeaways:
- Resveratrol is compared to an accelerator pedal for sirtuins, enhancing their activity.
- NAD is essential for sirtuins' function and is crucial for many bodily chemical reactions.
Notes: Speaker explains the role of NAD in conjunction with resveratrol for sirtuin activation.
Tone: Explanatory

“neuroplasticity might actually be regulated by these things like the sirtuins.”
Main Takeaways:
- Sirtuins, a group of proteins, are suggested to have a regulatory role in neuroplasticity.
- Sirtuins are also known to control memory in neurons.
Notes: Discussion on the role of sirtuins in neuroplasticity
Tone: Neutral
