What about other benchmarks used by experts? There are no federal limits on the amount of lead that dietary supplements may contain. But the FDA does publish something it calls an “interim reference level”—a guideline for reducing the potential adverse effects of dietary lead exposure—which is 8.8 micrograms per day for women of childbearing age,…
“Sleeping on your stomach tends to worsen back pain,” says Nnaemeka Echebiri, MD, a physiatrist at the Hospital for Special Surgery in New York City. When your hips sink into the mattress, they force your lower back into a hyperextended or overarched position. This stresses the small joints that connect the vertebrae—known as the facet…

Retailers and manufacturers commonly cite the cold-cranking amps (CCA). This is a measure of the power available for 30 seconds at zero degrees. A higher number means more power, and this is typically found in batteries marketed as “northern” batteries and from pricey absorbed glass mat (AGM) batteries. (You can upgrade your car from a…
