Recently, headlines have proclaimed that vitamin D is ineffective, that we shouldn’t bother testing for it, and that most people shouldn’t bother taking it. Pushing back on those assertions is Dr. William Grant, one of the world’s foremost vitamin D researchers with over 60 published studies. His latest paper explains why research on vitamin D is plagued by methodological errors and colored by bias against nutritional supplements that might supplant pharmaceutical drugs. Dr. Grant explains how vitamin D, far from being just a “bone vitamin”, can impact a wide range of conditions ranging from dementia and Alzheimer’s, cardiovascular disease, diabetes, mood disorders, and cancer; studies have shown it improves pregnancy outcomes and extends life; the latest research suggests a benefit for respiratory infections and Covid. We also discuss the important role sunlight exposure plays in vitamin D synthesis, and how wrong-headed health authorities have stigmatized sun exposure to great detriment. What levels are best? How much to take? Is there an upper limit? Dr. Grant is currently the director of the Sunlight, Nutrition, and Health Resource Center. Click HERE for part 2.
Two supplements. Two clinical trials. One company that does the research.
Magnesium is crucial for over 300 processes in your body — from energy production and muscle recovery, to sleep quality and stress response. Yet most Americans don’t get enough. In fact, in a peer-reviewed clinical trial published in the Journal of the American College of Nutrition, more than 75% of participants showed suboptimal magnesium levels before the study began.
Those who took Jigsaw MagSRT®— a time-release magnesium malate tablet — saw magnesium rise 30% over 90 days, and deficiency symptoms drop by 63%. Remarkable results, backed by real science!
For sleep and recovery, Jigsaw MagSoothe® delivers! In a 4-week clinical trial, participants saw a 17% improvement in sleep quality, felt 34% less stressed, and rated their satisfaction 85 out of 100. 82% said they’d buy it again.
MagSRT® for daily magnesium replenishment. MagSoothe® for calm, restorative sleep.
