Gary Brecka on NMN (Nicotinamide Mononucleotide) — 44 claims
“I typically start clients at 500 milligrams in the morning — NAD+ has an energizing effect and taking it at night can disrupt sleep for some people.”
Brecka typically starts clients on 500 milligrams of NMN in the morning, as NAD+ has an energizing effect and taking it at night can disrupt sleep for some people.
The published research provided (PMIDs 39531138, 36482258, 36797393, 33888596, 36002548, 38789831, and several reviews) does not contain extractable key findings, populations, or limitations in the da…
“I also stack NMN with resveratrol because resveratrol activates SIRT1, a sirtuin that requires NAD+ as a cofactor. They're synergistic — NMN provides the fuel, resveratrol turns the ignition.”
Brecka stacks NMN with resveratrol because resveratrol activates SIRT1, a sirtuin that requires NAD+ as a cofactor, making the combination synergistic.
The mechanistic premise of the claim — that SIRT1 requires NAD+ as a cofactor and that NMN raises NAD+ levels — is biochemically established and supported by several reviews and RCTs in the provided l…

Brecka stacks NMN with resveratrol because resveratrol activates SIRT1, a sirtuin that requires NAD+ as a cofactor, making the combination synergistic.
The expert's claim rests on two mechanistic premises: (1) that NMN raises NAD+ levels, and (2) that resveratrol activates SIRT1 in a way that is meaningfully enhanced by elevated NAD+. While several o…

Brecka stacks NMN with resveratrol because resveratrol activates SIRT1, a sirtuin that requires NAD+ as a cofactor, making the combination synergistic.
The provided research corpus focuses on NMN supplementation outcomes (glucose/lipid metabolism, arterial stiffness, insulin sensitivity, safety) and NAD+ biology, but none of the listed studies direct…
“I typically start clients at 500 milligrams in the morning — NAD+ has an energizing effect and taking it at night can disrupt sleep for some people.”
Brecka typically starts clients on 500 milligrams of NMN in the morning, as NAD+ has an energizing effect and taking it at night can disrupt sleep for some people.
The 500mg dosing recommendation has some basis in the literature: the multicenter RCT (PMID 36482258) used dose-dependent NMN supplementation in middle-aged adults and established safety across doses,…
“I also stack NMN with resveratrol because resveratrol activates SIRT1, a sirtuin that requires NAD+ as a cofactor. They're synergistic — NMN provides the fuel, resveratrol turns the ignition.”
Brecka stacks NMN with resveratrol because resveratrol activates SIRT1, a sirtuin that requires NAD+ as a cofactor, making the combination synergistic.
The provided research corpus consists entirely of NMN-focused RCTs and reviews examining NAD+ metabolism, glucose/lipid outcomes, and safety — none of which specifically study the NMN-resveratrol comb…
“I typically start clients at 500 milligrams in the morning — NAD+ has an energizing effect and taking it at night can disrupt sleep for some people.”
Brecka typically starts clients on 500 milligrams of NMN in the morning, as NAD+ has an energizing effect and taking it at night can disrupt sleep for some people.
The claim contains two distinct components: a specific 500 mg starting dose recommendation and the assertion that morning timing is preferable to avoid sleep disruption. While the available RCTs (e.g.…
“most of the human trials have used 250 to 500 milligrams per day. Some researchers use up to 1,000 milligrams.”
Most human trials have used 250 to 500 milligrams per day of NMN, with some researchers using up to 1,000 milligrams.
The published studies listed include RCTs and reviews that broadly align with the claim that human trials have used NMN in the 250–1,000 mg/day range. For example, the dose-dependent RCT (PMID: 364822…
“studies in mice show reversal of aspects of vascular aging, improvement in muscle function, and metabolic benefits.”
Animal studies on NMN show reversal of aspects of vascular aging, improvement in muscle function, and metabolic benefits.
Brecka's claim specifically concerns animal studies showing vascular aging reversal, improved muscle function, and metabolic benefits from NMN. The published research provided consists predominantly o…
“studies in mice show reversal of aspects of vascular aging, improvement in muscle function, and metabolic benefits.”
Animal studies on NMN show reversal of aspects of vascular aging, improvement in muscle function, and metabolic benefits.
The expert's claim specifically references animal studies showing vascular aging reversal, muscle function improvement, and metabolic benefits from NMN — this framing is broadly consistent with the an…
“There's published data now showing NMN supplementation raises NAD+ levels in humans and improves certain markers of metabolic health and physical performance.”
