“Using a Mendelian randomization analysis, scientists determined that people carrying genetic variants associated with low vitamin D levels have higher mortality from respiratory tract infections and higher all-cause mortality.”

“While Dr. Rhonda Patrick’s first video focused primarily on the micronutrients found in the various fruits and vegetables she put in her smoothie, this one, in addition to offering some modest changes on the recipe, instead focuses on the beneficial “hormetic” compounds that are NOT micronutrients.”

“A meta-analysis of resistance-training trials found that protein supplementation produced modest additional gains in strength and fat-free mass, with average fat-free-mass benefit plateauing near 1.62 g/kg/day. This is a group estimate, not a precise requirement for every older adult.”

“In a small immobilization trial, five grams per day of omega-3 fatty acids reduced the loss of muscle volume in young women compared with sunflower oil, supporting continued research on omega-3s and disuse atrophy. Heat is the fourth proposed tool.”

“The question of whether NAD+ is derived directly from NR or NMN in certain tissues rather than being salvaged from nicotinamide may, in particular, have implications for whether or not oral administration may be hampered in achieving maximal NAD+ status due to the fact that the process of salvaging NAD+ from nicotinamide is subject to feedback inhibition.”

“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.”

“EPA and DHA play particularly important roles in heart health because they participate in pathways involved in the production of hormones that regulate blood clotting and inflammation, help maintain healthy heart rhythms, and influence the contraction and relaxation of arteries.”

“Dr. Bruce Ames' Triage Theory Dr. Ames proposed that the body does a strategic rationing so that those proteins and enzymes in the body which are essential for short-term survival get their share of vitamins and minerals at the expense of other proteins and enzymes that are essential for long-term survival.”

“A few examples of genes with common polymorphism discussed are MTHFR and folate, NBPF3 and vitamin B6, FUT2 and vitamin B12, BCMO1 and beta-carotene, FADS2 and omega-3 fatty acids, CYP2R1 and vitamin D, PEMT and choline as well as APOE4 and FOXO3.”
