The Top Reasons To Take BioShield MD™

According To The Clinical Studies

Top Reason icon


When your immune system is stressed out, it can overreact to threats… releasing destructive proteins called cytokines which can damage healthy organs and tissue. But the seven flavonoids in BioShield MD™ have been proven to support a healthy, balanced cytokine response, in the face of dangerous environmental risks. This special formula delivers the targeted help that your immune system needs right now.

Natural Energy

The immune system is the “master switch” for your energy levels, which is why you get so tired when you’re sick. And if your immune system has become stressed over the years – from diet, lifestyle, and exposure to micro-toxins - then you’ll really start to feel the fatigue. That’s why BioShield MD™ is such a potent energy booster. It can help regulate your cytokine response, taking your immune system from “frayed, and on fire” to “calm, cool, and collected.” That means more energy for all the things you love and the feeling that you’ve got your life back.

Mental Health & Clarity

Immune system stress can make its way to your brain, where it activates microglia – just like what happens when you get a concussion. In the short term, it can mean fogginess and a depressed mood. And if this goes on for too long, it can mean really big brain health problems down the road. So the targeted immune support that you get with BioShield MD™ won’t just deliver better mental clarity today, but it can keep your brain sharp and healthy for the many decades ahead.

Relief For Overworked Joints

When immune system stress produces too many inflammatory cytokines, they often get deposited in your joints. Combine this with the years of overuse, and even simple movements become painful and tedious. Yet the flavonoids in BioShield MD™ have been clinically proven to reduce post-movement soreness. Not only that, but they can even help the body produce the new collagen, and extracellular proteins, it needs keep joints healthy with age.

Designed With Care

By Dr. Mark Rosenberg

All Sun Coast Sciences formulas are carefully designed by Dr. Mark Rosenberg, to ensure clinical dosing, of the best ingredients, with superior bioavailability. In BioShield MD™, you'll find...



It's the star of the show in BioShieldMD. This all-star flavonoid is shown to promote healthy, balanced levels of inflammatory cytokines in the lungs and joints. According to one double-blind, placebo-controlled study of 50 women, 500mg of Quercetin per day led to a “significant decrease” in early morning discomfort, post-activity discomfort, and swelling. And Quercetin can also suppress the growth of malignant cells, and cause them to self-destruct.


Elderberry Extract

A patented Elderberry Extract shown in clinical studies to have immune health properties including supporting healthy upper respiratory function. It’s prepared using a meticulously clean, lengthy process - so it retains all of the natural flavonoids and polyphenols that can support healthy immune function. It’s 100% free of solvents, cyanide metabolites, maltodextrin, and all the other nasty stuff that you’ll find in the drugstore brands. It has been paired with SunFiber, a patented prebiotic. This ensures that every capsule of BioShieldMD gets digested and not destroyed by your stomach acid.


Curcumin Extract

A proven antioxidant and inflammation-balance powerhouse, we've selected a high-grade, 95%-curcuminoid turmeric extract. It's a turmeric you'll feel with improved mental clarity, energy and joint comfort.


Cocoa Extract

Out of the top 1,000 flavonoid-rich foods, cocoa contains the highest amount of flavonoids per milligram. The specific flavonoids found in cocoa work by supporting healthy, balanced production of an inflammatory protein called Interleukin 1-Beta.


Boswellia Serrata

Boswellia has been shown to regulate production of an inflammatory cytokine called TNF-alpha, through pathways that other flavonoids are unable to regulate. It’s also been shown to support neurons as the brain gets older, and to promote feelings and calm and wellbeing.



This flavonoid is produced by grapes, to protect them from harsh sunlight, and is most often found in red wine. Multiple studies have shown that it support healthy, balanced production of an inflammatory cytokine called NF-kB. And Resveratrol has also been shown to promote stable blood sugar levels... for cleaner energy throughout the day.


Green Tea Extract

It's the best source of a flavonoid called a “catechin,” which supports everything from detoxification, to targeted immune response management, to the release of natural energy stores. And just as exciting, multiple studies have shown that the active ingredient in green tea - EGCG – is highly effective at targeting fat deposits.


Immunity Complex

We've included Vitamins C, D and Zinc in the BioShieldMD formula, to make sure you're getting your daily dose of these key immune support ingredients!

Frequently Asked Questions

With Dr. Mark Rosenberg

How does BioShield MD™ help with immunity?

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.

How does the immune system get stressed out?

These days, we’re exposed to a lot of stuff that wasn’t around when our immune system evolved. For example: the smoke and carbon pollution that we breath, the chlorine in our tap water, and the pesticides on our food. Frankly, the list goes on and on… our modern lives are practically a bath of micro-toxins.

Now think of what would happen if you swallowed a glass of pure chlorine or pesticide? You’d have an immediate, intense response, as your immune system tried to purge this poison from your system.

And that’s exactly what’s happening – but at a much lower level – every day. These daily “assaults” push your immune system to work overtime, leaving it stressed and unable to defend against bigger threats. You might not feel it at first, but over the years and decades, it really adds up!

How can BioShield MD™ give me more energy?

Your immune system is the “master switch” for how you feel. So when it’s overworked and stressed out, you never quite feel like you’re “at your best.” And it’s not the sort of fatigue that you can overcome with coffee!

But the flavonoids in BioShield MD™ can give your immune system crucial, targeted support. That allows it to “calm down.” And that means that all of the energy it was sucking up gets redirected back to your overall vitality.

How can BioShield MD™ give me more mental clarity?

When your immune system is stressed, it can also wear your brain down. Immune stress causes your brain’s glial cells – which constitute about 50% of its mass – to go into “attack” mode. Your brain doesn’t have any pain receptors, so you experience this attack as brain fog and moodiness. It’s unpleasant on a day-to-day basis, but if it goes on for years, it can lead to real problems and decline.

But as with energy, mental clarity can return when the immune response is calm, healthy and balanced – which is exactly what the flavonoids in BioShield MD™ can do.

How exactly do the flavonoids work?

Let’s talk about cytokines. They’re little immune system proteins that are sort of the “front lines of defense.” When your immune system is working well, they pick their targets carefully, and then go back into “standby.” But when your immune system is stressed, these cytokines can start to run rampant, and attack everything from harmless allergens, to your own healthy tissue!

The flavonoids in BioShield MD™ have been clinically proven to promote a healthy, balanced cytokine response to threats. They can send “signals” to your cytokines about how best to respond to threats. Because yes… you do want your cytokines to be ready to attack – you just don’t want them roaming your body like immune vigilantes.

Is there anything I should take to get better results?

To start, there are some things that you can stop doing: eliminate as many “assaults” to your immune system as possible. I’ve created an “Immune Health” ebook which goes into great depth on this, but two quick wins are: eliminate as much processed and non-GMO food as possible, and stop smoking.

Beyond that, yes: I recommend a good probiotic, since all health starts in the gut. I also recommend a high quality fish oil, which can balance our unhealthy, modern Omega 3:6 ratio (more on this in the eBook, but short version is that it causes immune system stress). That is my ultimate “immune system stack,” and since we typically don’t get these from a healthy diet, they’re key to supplement.

Then of course, I recommend high quality Vitamin C, a Vitamin D3/K2 combo, and a good magnesium supplement. Those are the “immune system basics” – they’re possible to get with a healthy diet, but if that’s not possible, then supplements are a good addition.

I don’t feel comfortable ordering online, can I talk to someone?

Of course you can! Just call us at 1-888-281-6816. You’ll speak to one of our incredibly friendly Customer Happiness Agents (seriously, they’re really great to talk to), and they’ll be happy to answer your questions and help you place your order.

How long will it take me to start seeing results with BioShield MD™?

Most people report increases in mobility and flexibility right away, and many experience the rapid natural enhancements in energy and clarity, as well. The best results are achieved by people who regularly take BioShield MD™ for 8 weeks. Please use as directed.
