Dr. Peter McCullough Is One of Several Physicians Now Recommending This to Their Patients.
Dr. John E. Lewis, Ph.D., spent over two decades running clinical trials and publishing peer-reviewed research at the University of Miami Miller School of Medicine — then left to build something with it. The formula is now used personally by physicians across the country, including internists, primary care doctors, and Dr. Peter McCullough, MD, MPH.
“Psychologically, I feel better now thanks to Dr. Lewis — that I am doing something about this. I have it at work. I put it in a small amount of water and drink it quickly. It tastes good.”
“As a physician researcher, knowing that the products I use with my patients are evidence-based is essential. The published science supporting Daily Brain Care’s formulation is among the most rigorous I’ve reviewed for a dietary supplement.”
“My patients want to stay mentally sharp and participate fully in life as they age. I appreciate being able to recommend a supplement with genuine published research behind the formulation. Patients who take Daily Brain Care consistently report improvements in focus and mental clarity.”
“I recommend Daily Brain Care to patients looking to support brain health and immune function. I take it myself every morning — it gives me reliable nutritional support backed by published research.”
Cognitive decline affects a large and growing share of older Americans, and most families know what that looks like up close. Dr. Peter McCullough is one of them — he’s spoken on his program about his own family’s experience with it.
He takes Daily Brain Care daily, and he’s said so publicly, to an audience of hundreds of thousands of readers.
At the close of one of their conversations together, McCullough addressed his audience directly. These are his words, unedited:
“Dr. Lewis, thank you so much for joining us. You’re one of the few repeat guests I’ve ever had on the program — because you are just filling such an important role that we need right now in nutritional science and in the whole field of neurodegeneration.”

McCullough also described how he keeps himself mentally active in multiple ways, including physically writing with pen and paper — a habit he cited as meaningful for brain health.
He then shared a link to Dr. Lewis’s website with his full audience. That is the sequence that brought many readers here.
Most brain health supplements lead with whatever ingredient is popular this year. Lewis built this one around what he’d spent two decades actually studying: polysaccharides from aloe vera and rice bran, almost entirely absent from a typical American diet. Every ingredient below is there because of what it does, not because it sells.
Pharmaceutical-grade extraction of the active polysaccharide fraction at the center of Dr. Lewis’s published research. Not the aloe gel at your pharmacy, which is roughly 99% water.
The layer removed when brown rice is processed into white.
Compounds studied for their role in immune function.
Choline, necessary for brain and heart health, and phosphatidylinositol, which supports healthy metabolism and cellular function.*
Replenishes glutathione, the body’s master antioxidant.
Many customers report sleeping better.*
“As a retired physician I approached this skeptically. I read the actual published study — not a summary, the study itself — and the data is legitimate. The methodology is sound. I’ve been taking Daily Brain Care for six months. My word recall feels better. My mental stamina during long reading sessions is better.”
“I’m 71 and I’d been noticing the kind of mental fogginess that just comes with getting older. Four months in — the brain fog I’d accepted as my new normal is lifting. I feel sharper. I don’t say that lightly.”
“I wanted a brain supplement with published science behind the ingredients — not just marketing language. Dr. Lewis’s research gave me that confidence. Three months in, my husband and I are both encouraged by what we’re noticing.”
Thousands of supplements are on the market. Almost no company built one the way Lewis did — spending two decades as a working research scientist before deciding the people who needed this deserved direct access to it, not just a credential on a label.
Lewis takes it every day. Has for over a decade. McCullough, after reviewing the published research, started taking it too. Neither is being paid to say so — the science is what earned the decision.
