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

Suggested Use: Take 1 to 5 drops per day for 2 months (1 drop = 1,000 IU Vitamin D3). Consult your physician before use and recheck blood levels after 2 months.

Instructions for Use: Slowly squeeze the dropper top drawing the solution into the dropper tip, then dispense each drop in 1-second increments.

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.

Not Chuck-It Durable
Color: Orange & Blue Squirrel, Size: 4.7 inches (1 Pack), Color: Orange & Blue Squirrel, Size: 4.7 inches (1 Pack)
Sadly only lasted an hour. My dog likes to pull apart toys over the course of a few months, with the exception of Chuck-It toys. They usually never get destroyed by him. I think its a good product but if you are looking for the durability like other toys from Chuck It - just wanted to share this is not the toy for you! Made him happy so not regretful of buying it, just wish it lasted longer. Here is him posing with it after he took bites of it like it was an apple.

1st one lasted over 3yrs, 2nd started falling apart in less than a week....
Color: Orange & Blue Roller, Size: 7.5 inches (1 Pack), Color: Orange & Blue Roller, Size: 7.5 inches (1 Pack)
My dog really loves this toy. He’s a 5yr old border collie. He doesn’t work at tearing up his toys but he does shake his toys. I bought his 1st Chuckit it indoor football over 3yrs ago. It held up very well and had normal wear and tear I’d expect from a chuckit toy to have. It developed a small tear in fabric about 6months ago. As it was still mainly intact, I let him continue to play with it. Then the tear widened and I felt good time to replace, so I ordered one from Amazon. He was ecstatic to have a new one. I was quite disappointed though as in under a week from giving it to him(he’s always supervised during play so I do know what he does with his toys and he doesn’t work at them to tear them up) I noticed a tear down the seam that was bigger than the other one had for 6months. Over the next few days, tear widened. Now cover is completely off of inside. I’m really disappointed in the quality. I’m not sure if the quality of the toy is less than when I got his first one(which I bought in a pet store such as petsmart) or if for some reason because I purchased on amazon, they are of lesser quality. I do know for a fact as I supervise his play and with his favorite toys(and usually his spendier toys) they get put up when it’s not play time. He has his other toys that he can play with anytime. I have ran also into Kong toys (Wubba) that has come apart quickly in under a month,but those were both bought on amazon and at a retail store, so I don’t know if amazon is distributing toys of lesssr quality or if toy brands that have held up in past (Kong Wubba & this Chuckit football) are just being made of lesser quality. My dog’s style of play hasn’t changed nor has his supervision. That being said, my dog absolutely LOVES this toy. I want other users to be forewarned that I’ve had 2 of this product for my dog, they both developed a tear down seam, that eventually led to outer fabric shell coming off of the inner part of the toy. Yes my dog does shake his toys but 1st lasted over 3yrs, 2nd lasted less than a month and is in worse condition than the first. I may purchase this toy again as it’s one of his favorites just to see if the 2nd one was a fluke. Had I paid more than $6.19(I’m a prime member and it was an add on product) I most likely wouldn’t purchase a third one. I’m willing to see if the third one will last at least a yr. if it starts coming apart in less than a week again, I’ll have my answer which would be that chuckit has resorted to making their toys of lessor quality. I hope that’s not the case because they are one of only a couple of brands I hold in high regard for their good quality and durable dog toys. Please see picture. It’s his toy in less than a month. The outer material came off during play last night. It lasted less than a month from time I gave it to him to play with. 5/22/18 update. I bought him a 3rd indoor fumblr, it last almost 3 months...I ordered him a 4th one. I gave it to him Friday, today is Tuesday, his 4th one is already coming apart at the seams. When I ordered 4th fumblr, I bought 2 at the same time, they were $5.19 each(prime member add on price). I’m glad I did because now they are twice the price at now over $10. I very highly doubt I will buy another indoor fumblr unless price drops in half again. This last one that I gave him 4-5days ago, it hasn’t been his daily favorite toy. He’s maybe played with it a couple hrs each day. My dog really LOVES this toy. I’m moving my rating down to a 1 Star from 2 as this toy has consistently come apart rather quickly. I’m very disappointed in the quality of this toy. He’s 5 1/2yrs Old now. 1st fumblr last over 3yrs, he’s gone through the other 3 in under 6months...had I paid over $10 each time, I probably would’ve stopped after the 3rd fumblr came apart. as it is now, I won’t but any more fumblrs by chuckit at this price....if price drops, after he’s gone through the 5th one I have put up...I may consider it...but not at over $10 for a toy that comes apart through normal play in under 5 days...

Dogs favorite toy
Color: Orange & Blue Roller, Size: 7.5 inches (1 Pack), Color: Orange & Blue Roller, Size: 7.5 inches (1 Pack)
I buy 4 of these every month for my dog. He won’t go anywhere without this ball. He sleeps with it, swims with it, goes to the vet and carries it around in his mouth to show off. It’s borderline a problem. My dog is a large breed and plays hard so I do purchase often because the strings unravel and the ball itself is foam so breaks down into little pieces after a few days of playing. I love that it is fragile on his teeth and jaw. We can play catch indoors because it is soft.
