Tanning pills can pose serious dangers, dermatologists warn: 'Consumers should be aware'
Some people are trading UV rays for tanning pills, as numerous social media influencers have raved about how these supplements have given their skin a tan glow. But are they safe?
These pills contain a variety of ingredients – including L-tyrosine, beta-carotene and astaxanthin – that could potentially have a color-changing effect on the skin.
Doctors are warning that this alternative means of bronzing the skin can come with risks.
DOES SUNSCREEN CAUSE SKIN CANCER? DOCTORS DEBUNK CLAIMS GONE WILD ON SOCIAL MEDIA
As of a March 2022 notice from the U.S. Food and Drug Administration, there are not currently any FDA-approved pills for tanning the skin.
The FDA confirmed with Fox News Digital that this has not changed as of today.

“Nevertheless, pills bearing tanning claims continue to appear on the market,” the FDA wrote. “Consumers should be aware of risks associated with such products, as well as doubts about their efficacy.”
One of the biggest risks is that some people might assume they’re more protected from the sun based on their darkened skin tone, according to Dr. Alexis Young, a dermatologist at Hackensack University Medical Center in New Jersey.

“I can assure you [that] is not the case,” she said to Fox News Digital. “The effect of these pills provides no SPF protection from the sun’s damaging UV rays, which can increase our risk of skin cancer – including melanoma, the deadliest form.”
These pills often contain a pigment called canthaxanthin, which accumulates in the skin and eyes, the dermatologist added.
With prolonged use at high doses, this pigment can potentially lead to liver damage, Young warned.

“Symptoms may include fatigue, nausea, abdominal pain and jaundice,” she said.
“Canthaxanthin deposits in the retina can potentially cause blurred vision, night blindness and even permanent vision loss.”
Tanning pills may also cause other side effects, Young reported, including nausea, vomiting, diarrhea, headaches and allergic reactions.

In addition to canthaxanthin, tanning pills can also contain other elements, such as beta-carotene and L-tyrosine.
“While generally considered safe, excessive beta-carotene intake can be harmful, especially for smokers, as it may increase their risk of lung cancer,” Young said.
“L-tyrosine … may interact with certain medications and can worsen pre-existing conditions like hyperthyroidism.”

Board-certified dermatologist Dr. Mina Amin, of California Dermatology Specialists, also reacted to this trend in an interview with Fox News Digital, noting that carotenoids – which are often found in these supplements – are what gives fruit their color.
“As dermatologists, we actually see this when someone eats too many carrots,” she said. “They can also get a similar ‘tan’ effect that presents more as an orange color, which often starts to appear on their hands and feet first.”
“The safest approach is to avoid tanning altogether and embrace your natural skin tone.”
Amin echoed that an excess of carotenoids can cause liver damage, as they’ve been associated with an increase in alcohol-induced swelling and inflammation when ingested in high doses.
Manhattan dermatologist Dr. Brendan Camp also does not recommend the use of tanning pills, he told Fox News Digital, as they typically have to be taken at higher doses to induce visible changes in the skin’s pigment.

“And their results are temporary, which means you would need to continue taking them to maintain the ‘tan’ they provide,” he said via email.
The expert pointed out that astaxanthin has been associated with gastrointestinal side effects like abdominal pain and diarrhea.
With tanning pills, “the potential risks, particularly for skin cancer and liver damage, outweigh any perceived benefits,” a dermatologist commented. (iStock)
Tanning pills are “not considered safe” even if dosage instructions are followed, according to Young.
“The potential risks, particularly for skin cancer and liver damage, outweigh any perceived benefits,” she said. “It’s important to remember that the FDA has not approved any tanning pills as safe or effective.”

Amin agreed that there is “simply not enough evidence to support the use of these supplements to tan the skin.”
“Given the unknown safety profile, I recommend avoiding using these pills at levels that can lead to a tan,” she added.

For alternative tanning options, Amin suggested using an at-home self-tanner.
Young also prefers self-tanning products and sunless tanners, including lotions, mousses and sprays, which provide a temporary tan “without exposing your skin to harmful UV rays.”

She also recommended professional spray tans that offer a “more natural-looking” custom tan.
“Remember, the safest approach is to avoid tanning altogether and embrace your natural skin tone,” she said. “Protecting your skin from sun damage is crucial for maintaining long-term health and preventing skin cancer.”
Fox News Digital reached out to several tanning pill manufacturers requesting comment on potential safety risks.

A highly contagious digestive virus is surging across the U.S., experts warn.
Rotavirus, a double-stranded RNA virus, causes acute gastroenteritis — inflammation of the stomach and intestines — which can lead to severe diarrhea, vomiting, fever and stomach pain.
The virus primarily affects infants and young children, but there have also been outbreaks in elderly populations, such as nursing homes.
AT LEAST 46 CHILDREN DEAD AMID MEASLES OUTBREAK AS VIRUS SPREADS GLOBALLY
Data from the Centers for Disease Control and Prevention shows that in the week ending April 4, out of 2,329 rotavirus tests, 7.3% were positive for the infection. Last year’s highest infection rate was 6.77% as of the week ending April 19.

“We’re seeing a lot of rotavirus in the wastewater right now,” Dr. Marc Siegel, Fox News senior medical analyst, confirmed to Fox News Digital. “Testing for rotavirus is way down, but the percentage of positive tests is up.”
While the virus typically peaks in the spring, it is not currently slowing down, he noted.
Why cases may be rising
Patricia Pinto-Garcia, M.D., a medical editor at GoodRx who is based in California, said there are several possible reasons for the rotavirus spike.
“Vaccine rates are down overall among young children, as they decreased during COVID,” she told Fox News Digital. “This means there’s a growing number of infants and young children who are vulnerable to infection.”
The rotavirus vaccine series must be completed by the time a child is 8 months old, she noted.
HEALTH ALERT ISSUED FOR DENGUE OUTBREAKS SPREADING IN TRAVEL HOTSPOTS
As a result of the declining vaccinations, herd immunity isn’t protecting vulnerable children, according to Pinto-Garcia. “Children who haven’t finished the vaccine series yet, are too young to get vaccinated, or can’t get the vaccine due to medical illness are more likely to get exposed to the illness because other children aren’t vaccinated,” she said.
Siegel noted that before the vaccine became available, rotavirus resulted in 55,000 to 70,000 in the U.S. per year.

“I am concerned that the vaccination rate has been declining over the past seven years and is continuing to decline in the current climate of vaccine skepticism,” he said.
Surveillance methods are also much better than they used to be, Pinto-Garcia noted, which means public health experts are able to pick up and track cases better than ever before.

“But we see that rotavirus-related healthcare visits are also up, so improved detection is not the only reason we are seeing this spike,” she said.
The COVID pandemic also disrupted the pattern of infections, according to Pinto-Garcia, so it’s “tricky” to compare the current levels against older cycles.
“It’s possible that what we are seeing is still some post-pandemic rebound, but it’s unlikely that this year’s pattern is fully explained by just this factor,” she added.
Transmission and risk
Dr. Zachary Hoy, a pediatric infectious disease specialist at Pediatrix Medical Group based in Nashville, Tennessee, often sees young patients with rotavirus.
“Rotavirus is spread via the fecal-oral route, meaning that a person comes into contact with virus droplets from contact with other children or adults, or from contact with objects such as toys that have been contaminated with the virus from someone who is sick,” he told Fox News Digital. “This can lead to outbreaks, especially at schools where many young children share the same toys.”
“It’s possible that what we are seeing is still some post-pandemic rebound, but it’s unlikely that this year’s pattern is fully explained by just this factor.”
Rotavirus is associated with many dehydration cases in the hospital due to the degree of diarrhea, according to Hoy.
In some severe cases, the virus can lead to seizures due to electrolyte imbalances from dehydration and loss of electrolytes in the stool.

“Younger children do not have the reserves that older children and adults have, so they can become more dehydrated quicker and develop more severe electrolyte imbalances, leading to more severe infections,” Hoy said.
“Patients with problems with their immune systems or on medications that can decrease their immune systems can have more severe and prolonged infections, too.”
Treatment and care
Because rotavirus is a viral infection, antibiotics are not effective against it. There is no specific antiviral treatment for the condition, with doctors typically recommending supportive care.
“The mainstay of treatment is hospitalization for rehydration via intravenous (IV) fluids,” Hoy told Fox News Digital. “Sometimes it can take up to two to three days of IV fluids to help get patients rehydrated.”

Blood draws are often necessary to evaluate patients’ electrolyte levels, such as sodium, potassium, calcium and magnesium, according to the doctor.
“If these electrolyte levels are significantly low, sometimes patients need special IV solutions or individual electrolyte medications,” he added.

Dr. Daniel Park, medical director of the Pediatric Emergency Department at UNC Health in Chapel Hill, North Carolina, noted that most children recover with supportive care, but parents should seek medical attention if a child shows signs of dehydration. Those include decreased urination, lethargy or inability to keep fluids down.
“While rare, rotavirus can be life-threatening in vulnerable populations, especially very young infants or children with underlying medical conditions,” Park told Fox News Digital.

Prevention strategies
Given the lack of antiviral medications for rotavirus, doctors emphasize the importance of prevention, primarily the vaccine.
There are two rotavirus vaccines – Rotateq (a three-dose series) and Rotarix (a two-dose series). They are given starting at age 2 months as oral drops, not injections, according to Hoy.

“It’s important to get the rotavirus vaccines on schedule, because these younger infants are at greatest risk if they get rotavirus,” he advised.
Other recommended prevention methods include handwashing with soap and water.
Every day we’re faced with a zillion small choices: Go to sleep early, or watch one more episode of that Netflix drama. Call an old friend to catch up, or cruise social media. Of course, no single action will guarantee a long, healthy life or doom you to an early grave. But those little daily decisions do add up, and over the long term they can make a difference when it comes to both your longevity and your health span, the amount of life spent in relatively good health.
Scroll through this theoretical “day in the life” and select the option that best fits your typical day. Not every situation will apply perfectly, but think about which choice you’d be most likely to make. This isn’t a formal scientific assessment. The goal here isn’t to assign you a “good” or “bad” score, but to help you understand the central factors that shape the way we age and how long we live.

A study from Harvard Medical School indicates natural selection has favored the red hair gene, resulting in a potential increase in the number of redheaded people as humanity continues to evolve.
By analyzing nearly 16,000 ancient genomes spanning 10,000 years, researchers identified a list of traits that nature is actively pushing forward. Among the most prominent were the genetic variants for red hair.
“Perhaps having red hair was beneficial 4,000 years ago, or perhaps it came along for the ride with a more important trait,” the authors noted.

The study, published in the journal Nature, relied on a large database of ancient DNA from West Eurasia. Using new computing methods, the team was able to filter out random fluctuations in DNA to identify what it called “directional selection.”
Directional selection happens when a particular version of a gene gives an organism a strong survival or reproductive advantage, causing it to become more common in a population faster than it would by chance, according to experts.

Prior to this study, scientists only knew of about 21 such instances in human history, one of which was lactose tolerance. This new research uncovered hundreds more.
“With these new techniques and a large amount of ancient genomic data, we can now watch how selection shaped biology in real time,” Ali Akbari, first author of the study and senior staff scientist in the lab of Harvard geneticist David Reich, said in a press release.
COMMON EATING HABIT MAY TRIGGER PREMATURE IMMUNE SYSTEM AGING, STUDY FINDS
The data showed that genetic markers for red hair are among 479 gene variants that have been strongly favored over the past 10,000 years. One likely explanation, the researchers said, is a major shift in human history: the transition to farming.

As humans moved away from hunting and gathering and settled into agricultural societies, their environment and behavior changed radically, triggering an evolutionary “acceleration.”

While the Harvard study provides the first definitive statistical proof that red hair was actively selected during the rise of farming, the researchers noted that the exact prehistoric benefit still requires more study.
However, scientists have long pointed to vitamin D synthesis as a likely driver for the rise of these light-pigmented traits in northern climates.
