“Although the findings of a large meta-analysis published in the journal Annals of Internal Medicine indicated that there was no evidence to support the notion that consumption of saturated fat increased the risk of heart disease, the studies on which their conclusions were based were primarily observational.”

“There is so much to say when we talk about the NRF2 pathway and isothiocyanates like sulforaphane that we had to pack it into 47 minutes and break it into a few key sections. Key sections: For a more in-depth breakdown click the timeline link at the top of this page!”

“Similarly, the timing of eating and exercise, especially in elite athletes, has not been studied and may, in fact, require self-experimentation by the athletes as they find the perfect interval of fasting to support their optimal performance.”

“A national survey analysis estimated 2.6% severe deficiency, 22% moderate deficiency, and 40.9% insufficiency among US adults, although prevalence changes with the threshold used. These categories should remain distinct because insufficiency is not the same as clinical deficiency.”

“A 12-month randomized controlled trial found that vitamin D supplementation improved cognitive function, intelligence quotient scores, telomere length, and lowered oxidative stress markers in older adults with mild cognitive impairment (compared to placebo), suggesting that not only does vitamin D supplementation improve biomarkers of aging, but also functional outcomes.”

“A meta-analysis restricted to direct regional measures from MRI, CT, or ultrasound found a very small average hypertrophy benefit when creatine was combined with resistance training, with uncertainty around the pooled estimate and variation across sites and populations.”

“In a four-month randomized trial of 88 overweight, untrained middle-aged adults, daily doses of 500 or 1,000 milligrams improved some muscle and mitochondrial measures, while the primary outcome of peak power did not significantly improve.”

“Choosing a supplement that contains both glucoraphanin (the precursor to sulforaphane), as well as myrosinase (the enzyme that converts glucoraphanin to sulforaphane), is crucial to ensuring optimal sulforaphane delivery.”
