"BioShield MD is by far the best vitamin I've taken in a very long time. I'm a poor eater and often live on less-than-ideal food (aka junk food and Pepsi). Frequently unhealthy and tired. Looked for a vitamin but had poor luck finding one that seemed to "click" with me. A friend told me about BioShield MD and how much better they felt taking it. They sounded like a walking advertisement for BioShield and I accused them of being paid by you to "talk it up"! Negatively, I began taking BioShield and noticed an improvement in my energy and attitude. Figured it was all the hype from my friend until I missed a couple of days of no vitamins. What a nice difference in my energy level with BioShield every morning. Been taking it daily since that day. GOOD STUFF! Ran out recently and dragged my butt around until my shipment arrived. Boy, was I glad to see that box arrive! Won't run out again!"

How Strong Is Your Immune System?
Most of us don’t realize just how drained our immune systems are.
There’s chronic immune stress… that’s caused by things like weight gain, pre-existing conditions, too many antibiotic treatments, and plain old aging.
Then there’s acute immune stress… that happens when we don’t eat right, don’t get enough sleep, or when our nerves are frayed from work, the news, or lack of sleep.
(smoking and drinking don’t help, either)
Here’s the problem: immune stress builds up slowly. Over the years and decades, it saps your energy, clouds your thinking, makes you achy, and drains your desire.
It’s that unmistakable feeling that something’s “off” in your body, and your brain.
It’s like a battery, losing its strength over the years.
Most doctors would say that these are “normal” signs of aging. But they’re not - they’re the surest signs that your immune system needs support.
"The real deal! I am a 65 year old dentist and I know it sounds crazy but for years, I had at least two colds a year and a number of sinus issues. I started taking BioShield during 2021 and have now gone almost 2 years without even a cold. I am a big believer in this product, try it for six months and see if it does not, make a difference. It is worth your time and money!"

Support During Times of Immune Stress
Getting Full Immunity Support in One Formula
Frequent Travelers
What to Expect...
BioShield MD® is a daily use formula, especially during times of peak immune stress. Here’s what you might notice as you use BioShield® consistently:
Day 7-10
You may begin to feel a subtle but noticeable shift, like your body is finally exhaling after years of immune “overdrive.” Energy stabilizes. Fog lifts. You breathe a little deeper.
Day 30
You’re waking up sharper, lighter, and more mobile. The full-spectrum flavonoids, especially Quercetin, Curcumin, and Resveratrol, are supporting healthy cytokine activity in your joints, your lungs, and your brain. You feel calmer, clearer, and more like yourself.
Day 60
The transformation accelerates. Movement feels freer. Breathing is easier. Your mood and motivation are higher, and digestion feels smooth and predictable. It’s as if your immune system is finally working for you, instead of against you.
Day 90
You’re fully in sync. Most people report steady, consistent energy all day long, minimal aches and discomfort, and a sense of clarity that hasn’t been there in years. Immune balance becomes your body’s new default, and that means better resilience, less inflammation, and a feeling of strength and vitality that shows up in everything you do.
Beyond...
Many customers say they didn’t realize how much better they felt… until they stopped. That’s because a calm, balanced immune system supports everything: brain, joints, digestion, and mood. Keep going, and enjoy your best life along the way.

Dr. Rosenberg on BioShield MD®
“I’ve spent the last two decades studying how immune stress silently affects our health. Most people think of the immune system as something that only matters when we’re sick, but that’s a myth. When it’s out of balance, even slightly, your body begins releasing cytokines that trigger fatigue, joint discomfort, mental fog, digestive issues, and more. And over time, this occasional immune stress can compound.
So I designed BioShield MD® to give you full spectrum immune support. I take it every day, and so do my loved ones. In my clinic, it’s become the go-to foundation for anyone who wants to feel strong, think sharp, and stay active, no matter what season.
Dr. Mark Rosenberg, M.D.
Frequently
Asked Questions
Think back to a day when you were really stressed out… you were probably “on edge” and quick to anger, right? Maybe you even picked a little fight with a loved one, or even said something you regretted?
Well, it’s the exact same with your immune system. When it’s stressed out, it can become overaggressive, attack stuff that it shouldn’t, and make you feel worse.
So you can think of the flavonoids in BioShield MD® like “therapy” for your immune system. They help it relax, chill out, and refocus its strength on real threats.
