Amid post-debate cognitive concerns, doctor recommends 3 natural supplements to boost brain power
As doctors continue to discuss President Joe Biden’s concerning speech patterns and behavior during Thursday night’s presidential debate, Dr. Nicole Saphier is focusing on natural remedies for cognitive function.
“Cognitive decline is a hot topic right now,” Saphier — who is an associate professor at Memorial Sloan Kettering Cancer Center in New York City and director of breast imaging at Memorial Sloan Kettering in Monmouth, New Jersey — said during a Sunday appearance on “Fox & Friends Weekend.”
A proponent of natural remedies and herbs for certain aspects of health, Saphier recommended a trio of supplements to help improve mental focus and prevent dementia.

“When it comes to improving memory and reducing the risk of cognitive decline, my three favorites are Bacopa monnieri, ginkgo biloba and ginseng,” she told Rachel Campos-Duffy of Fox News Channel.
In studies with human participants, all three supplements have been shown to improve memory, improve visual recognition and potentially decrease the risk of cognitive decline, according to Saphier.

Some of the studies have even linked these supplements to a longer life span, she said.
“Now as we know, when it comes to dementia, oftentimes it only gets worse and doesn’t get better,” Saphier said.

“So you want to be eating healthy and leading a healthy life before it happens, to try and decrease your risk.”
Bacopa monnieri, ginkgo biloba and ginseng are all natural plants, Saphier emphasized.
“I like to take them in liquid nutraceutical forms, because that gets absorbed the best,” she recommended.

The doctor also pointed out that all supplements are not created equal.
“A lot of herbal supplements don’t really have positive benefits — they’re more of a marketing scheme,” she said.
“But there are some things that are backed by science, and that’s the only stuff I talk about.”
Here’s a deeper dive into the three she recommends.
1. What is Bacopa monnieri?
Bacopa (Bacopa monnieri) — also referred to as Brahmi — is a plant that’s been used in traditional Ayurvedic medicine for centuries, according to WebMD.
The plant could help to increase chemicals in the brain that assist with learning, memory and other cognitive functions, the website stated.

It also could potentially serve as a protective mechanism against Alzheimer’s disease, per WebMD.
Bacopa is generally safe for adults to consume by mouth in doses of 300-600 mg daily for 12 weeks, and can be added to hot water to make tea.
WebMD recommends speaking with a doctor first to determine optimal dosage, potential side effects and interactions with other medications.
2. What is ginkgo biloba?
Ginkgo (Ginkgo biloba) is derived from an extract taken from the tree species’ fan-shaped leaves, according to Mayo Clinic’s website.
“While some evidence suggests that ginkgo extract might modestly improve memory in healthy adults, most studies indicate that ginkgo doesn’t improve memory, attention or brain function,” Mayo Clinic states.

Gingko can be consumed in a pill, extract, capsule or tea.
“Don’t eat raw or roasted ginkgo seeds, which can be poisonous,” Mayo Clinic warns.

While gingko is generally safe for healthy adults to consume in “moderate amounts,” experts say it is best to consult your doctor about potential side effects and drug interactions.
3. What is ginseng?
A popular herbal medicine, ginseng is a plant that has long been used in medical treatments in Asia and North America, according to WebMD.
Although more research is needed to confirm its benefits, some studies have linked ginseng to improved mental focus.

“There’s some early evidence that ginseng might give a small, short-term boost to concentration and learning,” stated WebMD.

“Some studies of mental performance have combined ginseng with extract from leaves of the ginkgo tree, another traditional remedy said to help with dementia. While these studies are intriguing, many experts feel we need more evidence.”

Ginseng can be consumed in the form of dried herbs, tea, capsules or powder, per WebMD.
As with any supplement plans, it’s always best to talk early on with a doctor about dosage, side effects and drug interactions.

One walking habit could signal a healthier brain after 80, scientists say
NEWYou can now listen to Fox News articles!
Older adults identified as “super movers” are about half as likely to develop cognitive impairment than their peers.
That’s according to a recent study led by Stony Brook Medicine in New York, which evaluated the cognitive function of 4,000 adults 80 and over who participated in multiple aging and longevity studies over several years.
Among this group, 6% to 10% were classified as super movers, which means they walk at a much faster pace than others of the same age and gender — at speeds comparable to people three decades younger.
COMMON VITAMIN MAY INFLUENCE BRAIN AGING IN WAYS SCIENTISTS DIDN’T EXPECT
The super movers were found to have about half the risk of cognitive decline compared to seniors with typical gait speed.
The findings were published in the journal Neurology on June 16.

“The study reinforces that mobility and brain health are closely connected,” lead study author Dr. Joe Verghese, MD, neurologist at Stony Brook Medicine, told Fox News Digital. “This suggests that preserving mobility may be an important marker of healthy brain aging and resilience.”
‘LONGEVITY GENE’ MAY PROTECT THE BRAIN FROM ALZHEIMER’S BY BOOSTING DNA REPAIR, STUDY FINDS
The most intriguing finding, according to Verghese, was that super movers maintained cognitive function despite having similar dementia-related brain changes as their peers.
In postmortem brain analysis, there was no difference in dementia-related pathologies between the super movers and the slower walkers, the study stated.

“This suggests they may possess resilience mechanisms that help preserve brain function even in the presence of age-related changes,” he said. “Understanding these resilience factors could lead to new strategies for promoting healthy brain aging.”
As the study was observational, there were some limitations, and it does not prove that walking faster prevents dementia, the researchers noted.

“Other factors, such as cardiovascular health, physical fitness or genetics, may also contribute to both faster walking and better cognitive outcomes,” Verghese said.

This study adds to growing evidence that what’s good for the heart and muscles also benefits the brain, he noted, adding that “staying physically active remains one of the most effective, evidence-based ways to support healthy aging.”
“Walking speed is best viewed as a marker of overall health, not a treatment.”
“The broader message is that physical activity is important at any age,” Verghese said. “Walking is an easy step-up point because you don’t need any special equipment. You can do it inside or outdoors, and you can do it on a regular basis. You can walk with a dog, you can walk with a friend.”
Any activity is beneficial if it’s done regularly and with the right intensity, he added.

Rather than just trying to walk faster, the neurologist recommends that seniors focus on maintaining mobility through regular physical activity, strength training, balance exercises and good cardiovascular health.
“Walking speed is best viewed as a marker of overall health, not a treatment,” Verghese noted.
Major public health guidelines from the CDC and U.S. Physical Activity Guidelines recommend at least 150 minutes of moderate-intensity aerobic activity each week, such as brisk walking.

This can be achieved by walking 30 minutes a day, five days a week, or about 20 to 25 minutes most days. Another option is to engage in shorter sessions that add up over the day.

“You have to do it within your health limitations and medical conditions,” Verghese advised. “So if there are any medical concerns, I would get your physician to clear you before starting exercise.” The good thing about walking, he added, is that you can start at a slow pace and then gradually build up to a brisker pace.
“And then adding on strength and balance training, whatever age you are, I think is also important.”

Dr Oz warns Medicare scammers are stealing billions — and your personal information could be next
NEWYou can now listen to Fox News articles!
Washington, D.C. – Medicare fraud is a multibillion-dollar problem that government officials say threatens both taxpayer dollars and Americans’ personal identities.
In a July 6 interview with Fox News Digital at the Great American State Fair in Washington, D.C., Dr. Mehmet Oz warned that every dollar stolen through Medicare fraud is a dollar taxpayers lose – a problem that has worsened since the COVID pandemic.
“If I had to just pick one thing to focus on to make healthcare more affordable in America, I’d go to health fraud and all the waste and abuse that accompanies it,” said Oz, who is the administrator of the Centers for Medicare & Medicaid Services. “And just to put this in perspective, we think it’s about $100 billion a year.”

Medicare fraud can include billing for services that were never provided, overcharging for medical equipment, using stolen patient or doctor information, or performing unnecessary procedures, according to the U.S. Government Accountability Office.

As the Trump administration ramped up efforts to combat fraud, CMS reported $41.9 billion in Medicare program integrity savings in 2025, up 59% from $26.3 billion in 2024.

Medicare fraud not only harms the federal budget and steals from taxpayers, but exposes seniors to identity theft, unnecessary care, higher premiums and reduced access, Oz cautioned.

Removing corruption from the healthcare system will have the greatest impact among seniors, since “so much of the fraud is perpetrated against them,” the administrator said.
“I’m talking about people tricking seniors to give up their Medicare beneficiary numbers, which is like a credit card basically,” he said. “These scammers can take those numbers and use them for all kinds of illegitimate purposes.”

“People are stealing from you by pretending to send you drugs you don’t want, wheelchairs you don’t need, [and] services you never asked for or don’t benefit from,” Oz added.
To prevent this, he shared his top advice for seniors: Do not give your Medicare beneficiary number to anybody, do not answer questions on a phone call from an unknown person and do not give away personal information.

“These scammers are calling seniors, tricking them, and once they have key information, they can steal it,” he said. “And I won’t know it and you won’t know it.”
“We want to protect people who need these programs the most,” Oz went on. “You do that by making sure scoundrels don’t corrupt the systems and steal money out of the till that is designed to help folks in dire straits when they’re vulnerable and in need of services.”
Seniors should never share their Medicare information with unknown people, the administrator advised. (iStock)
Removing fraud could “double the life expectancy of the trust fund that makes all this possible,” Oz predicted.
“If you’re worried about Medicare being there when you’re ready to retire in a couple decades, depending on how old you are, and you’re concerned that it might not last because of all the fraud that’s hitting it … you’ve got a good [reason to] worry,” he said.

“If we take the fraud out, we could double the life expectancy, which means you, your kids, your kids’ kids … they could all benefit from this beautiful safety net program.”
