“Some of the factors contributing to these variable phenotypes include persistent damage to our DNA and mitochondrial dysfunction, driven by an altered NAD:NADH ratio, the latter of which has recently been shown to be improved by certain dietary supplements like nicotinamide riboside.”

“Dr. Patrick also discusses glucose, HbA1c, fasting insulin, kidney and electrolyte markers, hs-CRP, fibrinogen, thyroid tests, CBC, vitamin D, sex hormones, IGF-1, and the Omega-3 Index.”

“Because red blood cells turn over slowly, the test provides a longer-term view of marine omega-3 status than a recent meal and gives people a measurable way to evaluate diet or supplementation.”

“A later Framingham analysis followed 2,240 adults for 11 years and found that a red-cell fatty acid model including the Omega-3 Index predicted all-cause mortality about as well as a model using several standard cardiovascular risk factors.”

“Dr. Patrick therefore favors lower-risk tools for focus, including high-quality sleep, exercise, cocoa flavanols, deliberate cold exposure, and modest caffeine, before considering an addictive stimulant. Nicotine is not equivalent to tobacco smoke, but that does not make chronic use benign.”

“A randomized-trial meta-analysis found a higher atrial-fibrillation risk with marine omega-3 supplementation, with a stronger signal at doses above 1 gram per day; the included populations generally had cardiovascular disease or elevated cardiovascular risk.”

“In contrast, a similar large trial, STRENGTH - which evaluated a free fatty acid formulation of EPA and DHA at 4 grams per day, was stopped early due to the unlikelihood of producing a favorable outcome. Scientists have speculated why these similar trials have had such different findings.”

“It remains unknown whether these levels are sufficient for optimal immunological functioning. A large meta-analysis of 32 studies, spanning nearly 50 years, suggests that 25-hydroxyvitamin D levels below 30 ng/mL are associated with a higher risk of death from all causes.”

“The effects of heat exposure are broad and include improved immunity, better cardiovascular health, improved mood, and extended healthspan, the number of years we live in good health.
