The Many Blessings… And One Fatal Flaw... Of Vitamin D3

Doctors around the country have been calling Vitamin D a "super vitamin," and for good reason. Research shows that Vitamin D helps support strong, healthy bones... an upbeat mood... a balanced immune response... and deep, restful sleep.

And since 80% of us are deficient in this super vitamin, it’s not a surprise that Doctors recommend it.  But there’s something that most of them don’t know:  taking vitamin D on its own may harm you more than help you. That's because one of Vitamin D’s many benefits is greater calcium absorption… the problem is, it doesn’t control where this calcium goes. And that can lead to: 

  • Excessive calcium build-up in your arteries
  • Reduced blood flow to your brain and heart
  • Formation of kidney stones
  • Excess calcium in the urine, blood, and joints

In other words, you need adequate Vitamin D to be happy and healthy... but standard Vitamin D supplements can create more problems than they solve. Isn’t there any way to optimize your Vitamin D levels, without risking dangerous side-effects?

D3 Shield: All The Benefits of Vitamin D3, Without The Cardiovascular Risk

Dr. Steve Sisskind believes in the fundamental idea that “you are what you eat.” Some foods can be incredibly healthful, while others can cause society’s most severe diseases — like diabetes, cancer, Alzheimer’s, and heart disease.

The good news is that anyone can use the power of nutrition to transform their health and vitality.

D3 Shield gives you the proper clinical dose of Vitamin D3, but it does more than that. It also gives you Vitamin K2, in its most bioavailable form MenaQ7. Vitamin K2 is the “Calcium Coach Of The Body”, which ensures the extra calcium goes to your bones and NOT your arteries, kidneys, or joints. So yes, D3 Shield can correct Vitamin D deficiency, but it also ensures that you don't wind up with dangerous calcium deposits in your soft tissues.

By combining these two ingredients, D3 Shield unlocks the full benefits of Vitamin D throughout your body. It ensures calcium gets placed in your bones, making them stronger... it naturally improves energy production in your cells... it can help strengthen brittle bones, and improve your walking-about comfort... it can help you achieve deeper, more restorative sleep... and it even promotes a balanced immune response, making you feel clearer and better than you have in years.

Vitamin D3

If you frequently feel exhausted or have trouble getting quality sleep... if you have occasional muscle pain or find yourself in a sour mood... if you experience uncontrollable fatigue... then you may already be suffering from Vitamin D deficiency.

That's not surprising. Our bodies are supposed synthesize Vitamin D3 from sunlight exposure. But thanks to our modern indoor lifestyles, 57% - 82% of adults are Vitamin D deficient... even in sunny states like Florida or Arizona. To make things worse, our bodies' natural ability to produce Vitamin D declines by as much as 75% as we age. That's why it makes so much sense to supplement with Vitamin D3 — as long as you also get its all-important partner, Vitamin K2.

Vitamin K2

Vitamin K2 is the “Calcium Coach Of The Body”. In other words, it’s the signal that makes sure calcium gets into your bones, instead of your arteries, kidneys, or joints. This is critical, because Vitamin D supplements increase the levels of calcium you absorb from your diet.

But keeping your arteries and joints free of excess calcium is not all Vitamin K2 does. Research has shown that Vitamin K2 also protects your mitochondria — the "energy batteries" of your cells – from damage by free radicals. Many doctors and researchers believe that damaged mitochondria are one of the leading reasons we feel the effects of aging. And that’s why being able to protect your mitochondria is one of the many reasons why Vitamin K2 is so exciting.

The One-Two Punch That Gives D3 Shield Its Powerful Effects

When your body doesn't have enough calcium in your blood, it sucks the calcium it needs out of your bones. Spongy, soft bones are easily fractured — and they can even cause discomfort or pain. But between the Vitamin D3 that helps you absorb extra calcium from your diet... and the most potent, bioavailable form of Vitamin K2 known as MenaQ7 that gets the extra calcium into your bones... D3 Shield will have you feeling like you have the strong, antifragile bones of a 20-year old. But that’s just for starters.

Numerous scientific studies have shown that Vitamin D3 and Vitamin K2 have positive effects throughout your whole body. From fighting free radicals, to promoting healthy reducing inflammation, to improving cardiovascular health, there’s nothing else like Vitamins D3 and K2.

Frequently Asked Questions

Does D3 Shield have any interactions or side-effects?

Every single ingredient in D3 Shield has been subject to numerous clinical trials, and has proven to be safe, effective, and without side-effects or interactions. Vitamin K2 in particular is safe to take with blood-thinning medication. The formula is non-addictive, and non-habit-forming. Of course, as with all supplements, you should check with your doctor to see what he or she has to advise.

How Does D3 Shield Actually Work?

If you’re suffering from low energy, fragmented sleep, unexplained aches and pains, or a sour mood, there's a very good chance you're also suffering from a Vitamin D deficiency. Vitamin D is critical for your whole body health — but odds are good that you’re simply not getting enough through sun exposure. D3 Shield helps correct this by bringing your Vitamin D levels into the optimal range.

But D3 Shield does more. It also contains Vitamin K2, in its most bioavailable and potent form, known as MenaQ7. This form of Vitamin K2 ensures extra calcium from Vitamin D supplementation goes directly to your bones — instead of stiffening up your arteries. The outcome is that with D3 Shield, you get all of the Vitamin D benefits, without any of the risks that standard Vitamin D supplements create.

Importantly, D3 Shield uses liposomal delivery. Here’s what this means: since Vitamins D3 and K2 are both fat-soluble vitamins, D3 Shield suspends these vitamins in oil. This allows the Vitamins to make it through your stomach, and into your bloodstream intact, so you get their full benefits each time you use D3 Shield.

Can you explain how the specific ingredients work?

Almost all cells in your body — including your heart, your brain, and your bones — have Vitamin D receptors. You need to have adequate Vitamin D levels in order for these receptors to get activated so your body can function properly. Without adequate Vitamin D, you can start suffering from various unpleasant symptoms, such as low energy, an overactive immune response, or painful, brittle bones. That's why D3 Shield contains the clinical dose of Vitamin D3 to make sure you have adequate Vitamin D levels.

D3 Shield contains a second superingredient — Vitamin K2, in its most bioavailable and potent form MenaQ7 — which works in tandem with Vitamin D3. One of the effects of Vitamin D3 is an increase in the calcium you absorb from your food. Vitamin K2 activates the proteins that prevent that calcium from settling in your arteries, kidneys, and joints and creating potentially dangerous and painful conditions. Instead, Vitamin K2 guides this extra calcium into your bones, making them stronger, more resilient, and healthier.

How Long Will It Take To Work?

Some customers report improvements in their health in four to six days, while for others it takes four to six weeks. It will depend on how deficient you are in Vitamins D3 and K2 to begin with. Our customers who report the best results typically take 2 sprays of D3 Shield every day on an ongoing basis. After all, if you are not getting adequate Vitamin D3 through sun exposure — and most of us are not — then you need to supplement with Vitamins D3 and K2 regularly. This is why we offer a VIP program for customers who want to make D3 Shield a daily part of their lives.

What If I Don’t Feel Any Different?

We'd be surprised, because we've created D3 Shield to have the best combination of Vitamins D3 and K2 — and most people are deficient in those vitamins. However, Dr. Sivieri knows that health isn’t “one size fits all.” So if you do try D3 Shield and find that it isn't elevating your mood, boosting your energy, or improving your all-around health, no problem. Simply write us an email or call us to ask for a refund, and we'll process your request quickly, professionally, and without hassle. And remember — your purchase of D3 Shield is guaranteed for a full year.
