I am a freelance science and medical journalist, fascinated by how the scientific process leads to incredible discoveries, but also can lead to publication bias leaning toward positive findings and minimizing negatives. With a bachelor’s degree in neuroscience from Lafayette College and a Master’s in Science and Medical Journalism from Boston University, I’ve written about clinical trial transparency, organ donation, and basic molecular biology for publications like The Scientist, The Atlantic, Undark.org, Kaiser Health News, and more. At MedShadow, I research and write about the sometimes unexpected ways that medicines can affect us, and what we can do if and when it does.

Two years ago, a researcher who specializes in the safety of breast milk was in the midst of breastfeeding her own child when she experienced a serious bout of postpartum depression. She had a televisit with her doctor, who refused to write her a prescription for antidepressant medications as long as she was still breastfeeding, even though the drugs are considered safe to take during pregnancy and breastfeeding.  “A lot of times, [the] health [of the new mother] isn’t prioritized as much as that of the infant. And that’s something that we really worry about,” says Kaytlin Krutsch, PharmD, a…

In the last week of September 2021, a group of more than 90 doctors and researchers published a call to action, cautioning against the liberal use of Tylenol (acetaminophen) during pregnancy.

The authors added, however, that Tylenol has long been considered one of the few safer options to treat pain in pregnancy, since Advil (ibuprofen) and opioids are considered riskier. They pointed out that, in some cases, a woman’s condition (fever and pain, for example) could be worse for…

In 2020, the protein supplement market was valued at $18.9 billion, with a projected yearly growth rate of 8.4 percent. This protein-mania isn’t a fly-by-night trend, either. People buy protein supplements — in the form of protein powders, chips, and bars — because it’s a vital supplement for health and fitness.  Amino acids are the building blocks of protein which your body requires to build and repair muscle, produce hormones and enzymes.  Protein…

Lisa Torelli-Sauer, a 39-year-old vegetarian, used to be one tired woman. She put her two young sons to bed at 7:30pm, and says, “I could barely stay awake long enough to say goodnight to them.” Her most recent blood tests from her annual checkup had been normal, so her doctor hadn’t recommended she take any vitamins or supplements. Yet, as her exhaustion persisted, she started taking a vitamin supplement that contains iron, magnesium, potassium, zinc and B vitamins. “I’m amazed at how much better I feel,” she says. “I’m able to stay up hours longer in the evening and no…

Dietary supplements — vitamins, minerals, herbs, botanicals, and a growing list of other “natural” substances — have migrated from health food stores to supermarkets and into mainstream medicine over the past 25 years. They are widely touted and often hyped, taken regularly by some 100 million Americans — half the adult population — and now “prescribed” and even sold by some doctors.
