Not All Vitamin D Is Created Equal

 

Vitamin D is crucial for your immune system, bone health, and even mood and cognition. Surprisingly, most Americans are deficient in the total body-health supporter — don’t be one of them.

Vitamin D Benefits

Vitamin D is needed at every level for whole body health. In fact, every single type of tissue in your body has receptors for Vitamin D. Your bones, heart, brain, muscles, immune system, you name it, all require sufficient Vitamin D to function optimally. Vitamin D is also the only vitamin that also functions as a hormone in the body, making it even more important to be sure you are not deficient or insufficient in this all-important micronutrient. 

Vitamin D Deficiency Is More Common Than You Think

Vitamin D deficiency is unfortunately all too common… According to a 2011 study, 41.6% of adults in the United States are deficient in Vitamin D, easily making this one of the most common nutrient deficiencies in the United States. The % of those deficient goes up to 69.2% in Hispanics and 82.1% in African-Americans. This is due to the fact that those of us with darker skin absorb less UV light from the sun, making Vitamin D synthesis more difficult, making Vitamin D supplementation even more important in these populations.

Vitamin D Triage Theory

Have you heard of the ‘Vitamin D triage theory’? This theory states that while Vitamin D3 is essential to almost every single aspect of whole body health, it can ONLY support all of these areas of our well being if we have enough. When Vitamin D is deficient, or even suboptimal, it will ONLY play a role in its most basic life supporting functions, such as regulating calcium levels in the blood stream. Its role in immune function, neurotransmitter balance, genetic expression, and more, will be slowed or stopped completely until Vitamin D3 is brought back up to optimal levels!

Vitamin D deficiency is easy and inexpensive to tackle! While it’s entirely clear that Vitamin D deficiency runs rampant in the United States, and throughout the world, the good news is that Vitamin D deficiency is easy to treat. Supplementation with the right kind of Vitamin D, and at the right dose, has been shown to quickly turnaround insufficiencies quickly and easily in most people.

Vitamin K2: The Bone Health Super Sidekick

My Vitamin D3/K2 formula is essential for calcium absorption and bone health. Vitamin D facilitates calcium absorption from the GI tract into the bloodstream and thus plays an important role in maintaining bone density. Once Calcium is absorbed, Vitamin K helps transport calcium from the bloodstream into the bone. Together these two vitamins help maintain appropriate calcium skeletal distribution. Calcium is critical for optimal bone density as well as normal growth.

Vitamin D supports neurological health and a positive mood! Often called the ‘sunshine vitamin’, Vitamin D3 plays a unique role in helping to regulate neurotransmitter balance in the brain, and therefore, mood and outlook. Due to its function in regulating serotonin and dopamine production and release in certain regions in the brain, Vitamin D plays a big role in helping to support and maintain a positive and happy mood.

Vitamin K2’s role in supporting bone & cardiovascular health is crucial. We all know that calcium is critical for our overall health, especially that of our bones. One important fact you may not be aware of though is that calcium needs support from Vitamin K2 to actually make its way from your bloodstream into your bone.

By ferrying excess calcium from the bloodstream into the bone, Vitamin K2 helps maintain both cardiovascular AND bone health through ensuring that calcium goes where it is needed!

Vitamin D is Crucial for Optimal Immune Function

Vitamin D3 is essential for supporting healthy immune system function. If you’re finding yourself under the weather occasionally, that may be a sign that your Vitamin D levels are suboptimal. Vitamin D works hand in hand with your body to modulate immune activity. Many immune cells have receptors for Vitamin D including macrophages, dendritic cells, monocytes, as well as T-lymphocytes and B-lymphocytes. This means that Vitamin D plays a big role in modulating both innate and adaptive immune responses. 

My Vitamin D3/K2 Liquid formula are perfect for anyone who:

  • Does not or cannot get adequate sun exposure
  • Takes a calcium supplement
  • Wants to support healthy immune function
  • Wants to support bone health
  • Wants to support a healthy heart and cardiovascular system
  • Needs help supporting a positive mood
  • Cannot swallow pills or prefers liquid form nutrients

FAQs

Is it safe to take Vitamin D3 and K2 together?

Yes, taking my liquid Vitamin D3 with K2 is both safe and highly beneficial. Combining vitamin D3 and vitamin K helps your body absorb calcium effectively to ensure it is directed to your bones. This powerful duo works together to support bone strength, cardiovascular health, and overall wellness. Our liquid Vitamin D3/K2 formula blends seamlessly into smoothies and drinks, making it an effective way to maintain your D3 and K2 levels.

What is the optimal level of Vitamin D?

Optimal levels of Vitamin D have been hotly contested for decades, with ‘normal’ being described by many physicians as anything above 20ng/dl. These days, many progressive doctors are waking up to how important Vitamin D is, and how much is required to support optimal health, thus many have changed ‘normal’ to anything above 30ng/dl. In my Functional Medicine clinic, Austin UltraHealth, I prefer to see my patients between 55-80ng/dl. Speak to your qualified healthcare provider to find out what level is best for you based on your age, weight, and health history.

How can I find out my Vitamin D levels?

If you’d like to have your Vitamin D levels checked, all it requires is a simple and inexpensive blood test. Many doctors will order this test for you if you ask them to, and it is especially important to monitor your levels when you are taking higher amounts in an effort to raise your Vitamin D to optimal levels. You may also consider ordering a Vitamin D3 test for yourself at a reputable website such as www.ultalabtests.com/amymyersmd.

When is the best time of day to take Dr. Myers’ Vitamin D3/K2 Liquid? Should it be taken with or without food?

My Vitamin D3/K2 Liquid can be taken at any time of the day, morning or evening. I prefer my patients to take it while the sun is up as that is when your body produces the vast majority of your Vitamin D3. My Vitamin D3/K2 Liquid should always be taken with meals if possible as both Vitamin D3 and Vitamin K2 are fat soluble, and taking the formula with a meal will greatly improve its absorption.

Can I take Dr. Myers’ Vitamin D3/K2 Liquid if I already take The Myers Way® Complete Multivitamin?

Yes, my Vitamin D3/K2 is safe to take as directed alongside The Myers Way® Complete Multivitamin when used as directed, provided you have spoken to your physician first to ensure that you are not taking any prescriptions that may be contraindicated (especially blood thinners), or should not take it for any other reason. Keep in mind it is important to monitor blood levels when taking Vitamin D over longer periods of time.

Is Dr. Myers’ Vitamin D3/K2 Liquid safe for pregnant women and breastfeeding mothers?

My Vitamin D3/K2 formula is safe to take while pregnant or nursing when used as directed, provided you have spoken to your physician first to ensure that you are not taking any prescriptions that may be contraindicated (especially blood thinners), or should not take it for any other reason. Keep in mind it is important to monitor blood levels when taking Vitamin D long term.

Helps with redness and softens skin
I have sensitive, mild rosacea skin. Had a facial recently and the aesthetician suggested I get a serum to help with moisturizer as I am almost 40. I’ve tried a lot of serums and either they are sticky and not really hydrating or break my skin out in a rash. This serum is amazing. Helps calm the redness in my cheeks and my skin is moisturized and soft all day. It feels a little sticky at first but it goes away. I apply in this order OSEA sea mineral mist toner to prep the skin, this serum and top off with Chanel La Solution 10 for sensitive skin.

Sensitive skin
Such a good product. I use after micro needling when skin is sensitive. Also a great product to use as a barrier serum when starting tretinoin cream.

Saved my skin during an eczema flare up
This saved my skin! I had an eczema flare on my face, and my usual products weren’t working. A friend recommended the Avene brand and within 3 days of using this rescue barrier serum, my flare was almost completely gone! This saved my face!

PLEASE REVIEW — FORMULA CHANGED!!!
I wish I would’ve posted a review PRIOR to the formula changing but just know that I LOVED this serum. I’ve struggled with hormonal acne (PCOS) and eczema for as long as I can remember. Finally, last summer my dermatologist put me on (3) different RX including Spironolactone and Accutane. I was so tired so I stopped everything except for CeraVe cleanser, retinol (Tretinoin) and CeraVe healing ointment. My made up skin routine was working until I used too much Tretinoin and burned my face. I had read great reviews about this product so I thought, I might as well try it — and IT WORKED! I’ve been using this product for almost a year and I loved it. However, 3 weeks ago when I ordered it, I noticed the bottle had a green tint. I could tell after one use that the feel of the serum was different, more watery, not as thick as it used to be. The smell was also different. Still, I kept using it for nearly 2 weeks and I experienced 2 breakouts! Sure enough, I stopped the product and within a few days, my skin was back to normal. I am very upset because as someone who has extremely sensitive skin, this worked but unfortunately, the new formula isn’t for me.
