Summary
- Nicotinamide adenine dinucleotide (NAD+) is central to cellular energy and mitochondrial health, driving redox reactions that produce ATP. Declining levels are linked to metabolic disorders, sarcopenia, and diabetes
- Alzheimer's disease has strongly associated with disrupted NAD+ balance, and research suggests restoring intake can reverse cognitive decline rather than merely slowing disease progression
- Animal studies show restoring NAD+ fully reversed advanced Alzheimer's features, including memory loss, inflammation, tau pathology, oxidative stress, and DNA damage, even after severe disease was established
- NAD+ functions as an upstream regulator of brain resilience, coordinating energy production, DNA repair, inflammation control, and protein processing, reframing Alzheimer's as a systems-level energy failure
- Practical strategies emphasize testing NAD+ status and supporting production safely via niacinamide alongside adequate intake of other B vitamins

| 0:58.3 | Hello and welcome to Dr. Mercola's Cellular Wisdom. |
| 1:03.3 | I'm your host, and today we are stripping away the noise of the wellness industry to focus on, well, the signal. |
| 1:05.1 | And as always, I'm joined by my co-host, who's here to make sure we actually understand |
| 1:08.9 | the biochemistry before we get too excited. |
| 1:29.4 | Good to have you. It is wonderful to be here. And frankly, excited is probably the right word for today. We aren't talking about a trend or, you know, a biohack. Yeah. We are talking about the machinery of life itself. Right. The mission for this deep dive is to unpack a specific analysis by Dr. Joseph Mercola. He's looking at a small molecule, his words, |
| 1:35.2 | that acts as the absolute engine for our biology. And I have to say, looking at the source material, the claims here are, well, they're aggressive. They are bold, but they're grounded in |
| 1:40.5 | something very, very fundamental. Okay, let's get right into it. The headline that caught my eye |
| 1:44.4 | reads, this small molecule reverses Alzheimer's disease progression. Study shows. Now, usually when I see |
| 1:52.0 | the word reverse next to Alzheimer's, my skepticism meter, it goes through the roof. Of course. |
