We Weren't Made For These Times

Georgetown M.D. Mark Sivieri is one of America's leading experts on treating chronic conditions. He's a "doctor of last resort" for his patients - the one they find after seeing four or five other doctors.

Dr. Mark Sivieri

After two decades, of treating thousands of patients who came in feeling tired, foggy, moody and achy, Dr. Sivieri came to a surprising conclusion:

Many of these conditions were caused by chemicals in the very food they ate, the water they drank, the air they breathed, and the personal care products they used. What kind of chemicals?

Pesticides on fruits and vegetables. Meat and fish raised on synthetic feed, and treated with hormones. Chlorine in tap water. Aluminum in anti-perspirants. Parabens and Pthalates in the bathroom. BPA in water bottles and can liners. The list goes on, and on.


The human immune system was designed to respond to foreign invaders like bacteria, viruses and fungi... not chemicals like these. But because these chemicals weren't around when the immune system was designed, it often mistakes them for "foreign invaders"... and sends inflammatory proteins in to attack.

So while these chemicals are not always harmful in small doses, daily exposure leads to what Dr. Sivieri calls an "overactive inflammatory response" in the body and brain. That's when too many inflammatory proteins cycle through the bloodstream for too long. They get stuck in joints, organs, muscles, and even the brain... where they go into "attack mode." And the results are predictable - and exactly what Dr. Sivieri sees in his patients, and measures in their bloodwork:


Too many inflammatory proteins in the bloodstream means less energy for the things we love. It means less mental clarity, and an uneven mood. It means we get achy more easily, and don't move quite as well as we used to. It means greater susceptibility to colds, viruses and bacterial infections. According to Dr. Sivieri, it feels like being "a little bit sick, all the time," which is exactly what can be expected when the immune system is stressed.


Daily Defense For The Body & Mind


Dr. Sivieri formulated VitaCell+ to help the human body and mind thrive, in the face of inescapable toxins in the food supply and environment.

VitaCell+ contains seven, clinical-grade plant extracts called flavonoids, which exist in nature to protect their host plants from environmental stresses. Each extract has been the subject of dozens of clinical trials. And Dr. Sivieri selected each extract for the real-world results they delivered to his patients: in both their bloodwork, and their subjective experiences.

These seven plant extracts have been shown to limit production of dangerous, inflammatory proteins. That means that the immune system gets a chance to rest, and save energy for the really bad stuff like viruses, bacteria and fungi. And when there are fewer inflammatory proteins in organs, muscles, joints and the brain, people simply feel better.

Energy is returned from an overstressed immune system. Mobility is restored, as inflammatory fires cool down in the joints and muscles. Mental clarity and an upbeat mood come springing back, as the brain stops hosting inflammatory battles. It's a huge life upgrade for anyone whose body and brain are awash with inflammatory proteins... and now, VitaCell+ is finally available to the public.

The Powerhouse Flavonoids That Give VitaCell+ Its Kick

 Flavonoids are the miraculous healing compounds found in nature’s most vital plant foods, including deep red cherries, bright golden turmeric, lush purple grapes, soothing green tea, and rich raw cocoa1. Originally discovered in 1936, we now know that flavonoids exist to protect their host plants from environmental stresses.

 And thousands of robust scientific studies2 have proven - beyond a shadow of a doubt - that flavonoids are the most powerful feel-good, mood-enhancing, energy-boosting compounds created by nature. After years of tests and experimentation, Dr. Sivieri found the seven same flavonoids kept on delivering results that his patients could feel… sometimes in three months, but often, in just a few short days. 

LongVida® Optimized Curcumin

Everyone knows that they should take curcumin, but what most don't know is that it often gets destroyed by the stomach. That's why Dr. Sivieri choose a UCLA-developed liposomal curcumin. The liposomal layer preserves and protects the curcumin from the harsh environment of the stomach, dissolves it in the GI tract, and delivers the free curcumin into target tissues. This exact curcumin has been the subject of over 30 clinical trials, and is 95x more bioavailable than standard, off-the-shelf curcumin.

CherryPure® Tart Cherry Extract

CherryPure’s clinical studies are exciting for anyone who wants more energy or mobility. In one study, weight lifters who trained with CherryPure were stronger, and less sore, following their workouts. Another study showed that endurance athletes who ran a half-marathon performed 13% faster, and reported a 34% reduction in post-race soreness. If CherryPure delivers these benefits to athletes, imagine what it can do for the rest of us!

Cocoa Extract

Cocoa was revered as a superfood by the Mayans, but even they didn’t know just how powerful it is. Out of the top 1,000 flavonoid-rich foods, cocoa contains the highest amount of flavonoids per milligram. The specific flavonoids found in cocoa, which are different than those found in curcumin, work by limiting production of a dangerous inflammatory protein called Interleukin 1-Beta. That’s why Dr. Sivieri chose it for VitaCell+.

Boswellia Serrata

Boswellia Tree extract has been a staple of Ayuverdic medicine for thousands of years, to improve mobility and flexibility. But it wasn't until recently that Western scientists came to understand just how powerful this tree resin extract really is. Boswellia has been shown to limit production of an inflammatory protein – TNF-alpha – through pathways which other flavonoids are unable to regulate. It’s also been shown to protect neurons as they age, to reduce unnatural anxiety, and to promote feelings and calm.


Resveretrol is produced by grapes, to protect them from harsh sunlight, and is most often found in red wine. Multiple studies have shown that it slows production of a dangerous inflammatory protein called NF-kB, which was the first reason Dr. Sivieri included it in VitaCell+. But resveretrol is also a voracious scavenger of free radicals, and has been shown to promote stable levels of sugar in the blood... for cleaner energy throughout the day.


Several landmark studies have shown that Quercetin specifically limits the inflammatory output of fat cells - a risk that Dr. Sivieri knew he had to target. Not only that, but Quercetin has been proven to increase the bioavaialability of resveratrol. Quercetin has also been called "nature's own histamine blocker," and it can be very helpful for people with food allergies. And perhaps best of all: when combined with Resveratrol, Quercetin can lead to a decrease in fat deposits.

Green Tea Extract EGCG

To round out his VitaCell+ formula, Dr. Sivieri selected Green Tea extract. It's the best source of a flavonoid called a “catechin.“ Study after study have revealed the wide-ranging benefits of catechins, 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.

Vit D 3

My husband of 32 years passed last Nov and the last 2 mos I have felt depressed and drowsy and down right lonely from Covid 19. With God in my life I will make it through this. I have felt less anxious since taking it. When I purchased it before I did notice less depression and anxiety and increased energy.

Amazing results with VitaCell+

VitaCell+ has saved my life! At least my quality of life! I've had super bad inflammatory syndrome for years and VitaCell+ brought it under control in only 2 weeks. I did have to double the dose for those 2 weeks, but now take only the 2 capsules a day as suggested. I also had my aging athlete husband start taking it and his aches and pains have gone away. We were so grateful to have VitaCell+ during this pandemic time. It has been a great immune support for us.

It's a miracle

I started taking VitaCell+ about 2 years ago and was amazed at being able to move without any pain, then I stopped taking it, why? I don't know, maybe I thought it was all in my head. Never should have stopped, all the joint pain returned. I'm back on it and will never stop, joint pain is gone and I feel like I'm in my 40's again.

Lots more energy!

I have been taking Viticell for about 6 months every morning with breakfast. I no longer have troubles waking up and getting started in the mornings nor have that afternoon “I need a nap feeling.” I have a lot more energy since taking Viticell.

Back to taking it regularly and feeling awesome! Also really appreciate knowing about the Cytokine's/Cytokine storms, related to CV19, and how this product works to reduce that inflammatory freak out.

…And The Doctor Behind The Formula

About Dr. Mark Sivieri

Dr. Sivieri’s life has been dedicated to the pursuit of great health... starting with his own. A competitive runner in high school and college, Mark was nearly derailed by an inflammatory injury. But when a chance visit with an unconventional doctor turned his life around, Mark knew that his life would be devoted to medicine.

After graduating from the Georgetown School of Medicine, and completing his residency at the University of Arizona, Mark moved back east, and quickly established himself at his clinic outside of Washington D.C. Patients with conditions as serious as Lyme and fibromyalgia came to know him as “the doctor of last resort” – the one who was able to help them, when everyone else had failed.

Now, in partnership with Vitalifi, Mark has become “the doctor of first resort” for countless Americans who have discovered his medical-grade formulas, as well as his cutting-edge advice for health and longevity.

Frequently Asked Questions

Does VitaCell+ have any interactions or side-effects?

The seven flavonoids in VitaCell+ are all extracted from Non-GMO, organic plants… they’re the “good stuff” that everyone can benefit from. All seven have been rigorously studied, and none have been shown to have any side effects or interaction risks.

And beyond the clinical studies, we’re proud to say that we’ve now sold over 100,000 bottles of VitaCell+, to happy customers across America. Not a single one has reported having experienced any adverse effects. Of course, as with all supplements, you should check with your doctor (and don’t be surprised if he or she is impressed!)

How Does VitaCell+ Actually Work?

If you’re suffering from low energy, brain fog, or aches and pains that won’t go away, there’s a very good chance that you’re also suffering from out-of-control inflammation. There are millions of little inflammatory wars going on in your organs, your joints, and your brain, and it’s making you feel awful. And while it’s tough to avoid the microtoxins and chemicals that start these wars, VitaCell+ can help prevent them from spreading. Its seven flavonoids shut down your body’s overactive, inflammatory response. That helps restore your natural energy levels, your mental clarity and mood, and the flexibility of youth.

Can You Explain How The Flavonoids Work?

When your body is exposed to stuff that it doesn’t recognize, it mounts an attack, with a protein called a cytokine. Think of cytokines as the policemen, who rush to the scene when there’s an attack. You want them there when the “bad guys” are really bad guys (like viruses and bacteria), but you don’t want to live in an oppressive police state, where they go after anyone that looks slightly suspicious. Yet that’s exactly what it’s like when your body’s inflammatory response is overactive. The flavonoids in VitaCell+ force an early retirement on the hyper, aggressive members of the cytokine police… and those who remain are able to do their job effectively.

How Do I Know If I Have An Overactive Inflammatory Response?

You can start by asking your Doctor to test your C-Reactive Protein and Sedimentation Rate. These are the two best tests that exist. But Dr. Sivieri has found that even when the tests come back “clean,” it doesn’t mean that a patient is out of the woods. In fact, many of Dr. Sivieri’s toughest cases manage to pass these tests with flying colors. That’s why we suggest that anyone who could be struggling with these issues give VitaCell+ a try, to see how it works for them.

How Long Will It Take To Work?

Some customers report feeling better in three or four days, others in three or four weeks. Our customers who report the best results have typically been taking it for three months. That gives VitaCell+ the time it needs to bring the inflammatory response back into balance, across the whole body, and for things to “cool down.” That’s why we offer 3-month and 6-month supplies, which are both backed up by our lifetime guarantee – we want customers to have the chance to make VitaCell+ a daily habit, and see just how much better they feel.

What If I Don’t Feel Any Different?

We’d be surprised, but it does happen for about 6% of our customers! That’s ok though – Dr. Sivieri knows that health isn’t “one size fits all.” No matter which VitaCell+ package you purchase, you’re protected by our lifetime guarantee. All you have to do is send us an email, or call us to ask for a refund, and we’ll process it quickly, professionally, and without a hassle.
