What is BioShield MD?

BioShield MD is an immune system supplement from Sun Coast Sciences. The supplement claims to support a healthy immune system using ingredients like curcumin, cherry extract, and resveratrol.

Just take two capsules of BioShield MD daily, then enjoy a strong immune system, youthful energy, sharp mental clarity, and relief from joint pain, among other benefits, according to the official website.

BioShield MD is priced at around $50 per bottle. You can buy BioShield MD through or, where the supplement has an average rating of 4.8 stars out of 5 among verified purchasers.

BioShield MD was created by a medical doctor named Dr. Mark Rosenberg. Dr. Rosenberg specializes in immunity research. He used his experience as a medical doctor to build BioShield MD’s formula, and he now recommends the supplement for supporting immune function.

BioShield MD was marketed under the name BioShield+ in 2020. In 2021, Sun Coast Sciences rebranded the supplement as BioShield MD.

Sun Coast Sciences and Dr. Rosenberg have specifically marketed BioShield MD online during the COVID-19 pandemic. Here’s how Dr. Mark Rosenberg explains how his supplement could support the body’s defense against COVID-19:

“…it’s my duty to help as many Americans as possible right now. There’s a big immune health issue right now. It’s a tiny little protein called a ‘cytokine’. And every study I’ve read shows that cytokines are directly linked to the health situation we’re currently fighting.”

By taking BioShield MD daily, you can purportedly support cytokines and immunity in your body.


How Does BioShield MD Work?

BioShield MD claims to use natural herbal extracts and anti-inflammatory compounds to help your immune system do its job.

By taking two capsules of BioShield MD daily, you can purportedly enhance your body’s self-defense mechanisms, among other benefits:

  • Support a strong immune system
  • Improved energy, clarity, and mobility
  • Support relief for overworked joints
  • Support key immunity pathways
  • Support cellular wellness and healthy aging

The BioShield MD website is filled with customers who claim to have experienced significant benefits after taking BioShield MD. Sun Coast Sciences claims their formula is linked with staying healthy, improving cellular aging, boosting mental acuity, and relieving overworked joints, among other benefits.

Too much inflammation makes it harder for your immune system to do its job. Too much inflammation is linked with a higher risk of illness and disease. BioShield MD claims to support normal inflammation, making it easier for your immune system to function.

To do that, BioShield MD contains ingredients common in other inflammation-supporting immune formulas, including turmeric, cherry extract, and resveratrol. These are some of the most popular and proven immune boosters in the natural world. BioShield MD has packaged all of these ingredients into one convenient formula.

Because of all of these benefits, Dr. Mark Rosenberg insists that “This is the immunity formula that every American needs right now.”

What is the 1-Minute Immune System Test?

BioShield MD is marketed online with claims of a 1-minute immune system test. By testing your immune system in 60 seconds, you can determine if you need to take an immune support supplement like BioShield MD.

In that video, Dr. Rosenberg explains simple steps you can take to test your immunity. There isn’t really a 60-second test you can perform at home to test your immunity. However, Dr. Rosenberg describes other strategies you can use to support immunity, including:

  • Three foods that stress your immune system
  • Guidelines for keeping patients safe
  • How the ingredients in BioShield MD can support immunity and provide other benefits

Overall, the goal of the 1-minute immune system test video is to decide if you have immune dysfunction – and that taking BioShield MD can help support immunity in multiple ways.

What Does BioShield MD Do?

BioShield MD contains seven flavonoids that support the benefits listed above. Flavonoids are natural compounds linked to healthy inflammation. Flavonoids have antioxidant effects: they neutralize free radicals throughout your body, which could lower inflammation.

By targeting inflammation, BioShield MD could support immunity. Dr. Rosenberg claims that BioShield MD specifically helps immunity because it has “been proven to support a healthy, balanced cytokine response.”

Cytokines are immune system components that your body sends to areas of infection or disease. When you have a healthy immune system, your body has a healthy cytokine response. It sends an appropriate number of cytokines to the affected area, and those cytokines do their job and heal your body.

If your body has an unhealthy or imbalanced immune system, then you might have an overactive cytokine response. Your body may have too many cytokines at the area of infection, for example, leading to excessive inflammation. In extreme cases, cytokines can overwhelm your body’s natural defenses entirely, and your immune system works against you to cause serious health problems.

Dr. Rosenberg also claims his formula targets “micro toxins” in your body. Dr. Rosenberg claims that your body is filled with small doses of toxins throughout the day. Over time, these toxins build-up, which could cause problems for your immune system. BioShield MD claims to help your body eliminate mycotoxins, making it easier for your immune system to do its job.

Meanwhile, to support mental clarity, BioShield MD uses ingredients that target overactive microglia in your brain. Dr. Rosenberg claims that poor immune system function can lead to overactive microglia in your brain. This can feel like mental fogginess or an overall feeling of poor cognitive function.

Finally, for joint function, Dr. Rosenberg added flavonoids that reduce post-movement soreness and help your body produce new collagen. Flavonoids can support healthy inflammation within your joints and between your bones. Collagen is the most abundant protein in the body, and higher collagen levels are associated with better joint health.

By taking BioShield MD daily, you can purportedly enjoy all of the benefits listed above.

BioShield MD Ingredients

BioShield MD contains seven flavonoids linked to inflammation and oxidation throughout the body. Some people take these ingredients individually for inflammation and immune function. Many people take daily turmeric or resveratrol supplements, for example, because they’re linked to immunity. With BioShield MD, you get all of these ingredients in one convenient place.


The seven flavonoids in BioShield MD include all of the following:

480mg of CherryPURE Montmorency Tart Cherry Skin Powder: BioShield MD contains 480mg of tart cherry skin powder, which is one of the most powerful antioxidants in the natural world. Cherry skin is particularly rich with vitamin C and other antioxidants, making it a popular ingredient in supplements like BioShield MD. Some people take cherry extract daily for inflammation and immunity. BioShield MD contains a strong dose of CherryPURE, a patented type of tart cherry skin extract.

400mg of Longvida Curcuma Longa Rhizome Extract (With 23% Curcuminoids): Longvida is a patented type of curcumin extract that works differently from the curcumin in a standard turmeric supplement. The Longvida curcumin in BioShield MD is surrounded by a liposome, a fat molecule that protects the active ingredients. That means more curcuminoids reach your digestive tract instead of being destroyed by stomach acid or absorbed by your body. Many people take turmeric supplements daily to support immunity and inflammation. The 400mg of Longvida curcumin in BioShield MD could provide significant support for immunity, energy, mental clarity, and more.

100mg of Boswellia Serrata Resin Extract (with 65% Boswellic Acids): Boswellia serrata has been used for centuries for inflammation and immunity. Today, studies show that Boswellia serrata works by regulating an inflammatory cytokine called TNF-alpha, or tumor necrosis factor alpha. Other flavonoids are unable to regulate this cytokine, according to Dr. Rosenberg. By regulating this inflammatory cytokine, the Boswellia serrata extract in BioShield MD can purportedly support immune function.

90mg of EGCG (As Green Tea Leaf Extract): Green tea is linked with health benefits. Today, studies show that green tea extract seems to work because it contains EGCG, a flavonoid linked with inflammation and immune function. EGCG is a catechin, and studies show it can influence immunity, inflammation, energy, and mental clarity, among other benefits. Some people even take EGCG for weight loss, and it’s a popular ingredient in many diet pills sold online today.

50mg of Quercetin (As Quercetin Dihydrate): Quercetin is a popular natural ingredient for antioxidant effects. Studies show that quercetin can limit the inflammation caused by fat cells. It also improved the bioavailability (absorption) of our next listed ingredient, resveratrol.

25mg of Resveratrol 50% (As Polygonum Cuspidatum Root Extract): Found in grape skin extract and red wine, resveratrol is a popular natural antioxidant linked to longevity, anti-aging, and other effects. Many people take resveratrol supplements daily for the purported benefits.

20mg of Cocoa Seed Extract (With 10% Theobromine): You may have heard that chocolate is good for you. This can be true. Cocoa is rich with theobromine, a flavonoid linked with inflammation, longevity, and immune function. Although BioShield MD does not contain a significant dose of cocoa seed extract, it could support longevity and immunity in various ways.

Other (inactive) ingredients in BioShield MD include a vegetable capsule (made from cellulose and water), rice flour, magnesium stearate, and silicon dioxide (as fillers, binders, and preservatives to hold the formula together).


Scientific Evidence for BioShield MD

Sun Coast Sciences has not completed any clinical trials on BioShield MD to verify it improves immunity, mental clarity, energy, or inflammation. The company has also not published its research in a peer-reviewed journal.

However, BioShield MD contains science-backed ingredients that have completed trials and studies. And, the formula was created by a genuine medical doctor: Dr. Mark Rosenberg. Although BioShield MD has not been individually studied to verify its effects on immunity, the supplement could support immune function and inflammation in various ways.

In this 2011 study, for example, resveratrol was linked to cytokine activity, blood sugar, and anti-diabetic benefits. Resveratrol is one of the most popular natural antioxidants in the world, and many people take resveratrol supplements daily for their purported health benefits.

Other studies have linked chocolate, cocoa, and theobromine to benefits. Cocoa bean is rich with a flavonoid called theobromine. In this 2000 study, researchers found that regular consumption of cocoa and chocolate was linked with longevity. Researchers found that cocoa reduced the expression of IL-1 beta, which could support immunity.

BioShield MD contains more cherry extract than any other ingredient. Cherry extract, including the specific CherryPURE used in BioShield MD, has been shown to support inflammation, endurance, and overall health in multiple studies. In this 2016 study, for example, researchers found that short-term supplementation of tart cherry extract in athletes improved performance in an endurance challenge. After taking tart cherry extract, athletes ran a half marathon. Athletes in the tart cherry group had 13% faster half marathon race times, on average, compared to a placebo.

Dr. Rosenberg claims his formula specifically targets cytokines. Cytokines are components of your immune system that target inflammation and disease throughout your body. In this study, researchers analyzed the effects of cytokines and their role in disease. Researchers concluded that targeting cytokine imbalances can help control disease.

Many people take curcumin and turmeric supplements daily for immunity. BioShield MD contains a strong dose of Longvida curcumin, a specific type of curcumin wrapped in a fat molecule for protection. Multiple studies have linked turmeric and its active ingredient curcumin to immunity. It’s been used for centuries in India for that reason, and research shows that curcumin could “spice up” your immune system by supporting antibody responses in various ways. One study found that curcumin has beneficial effects in arthritis, allergy, asthma, heart disease, diabetes, and cancer because of its ability to impact the immune system.

It’s possible that taking an antioxidant supplement like BioShield MD over a long period could weaken immunity. New research published in Nature found that “excessive use of the antioxidative supplements may compromise microbial defense.” However, researchers found that normal consumption of antioxidant supplements was not linked to poor immune function.

Overall, studies show that the ingredients in BioShield MD could support immunity and inflammation in various ways. You may be able to find larger doses in competing supplements, but BioShield MD contains transparent ingredients linked to immune function in multiple studies.
