Let’s talk about the potential benefits of taking vitamin D3 and vitamin K2 at the same time.

Vitamin K2 and vitamin D3 work closely together. Vitamin D3 supports the absorption of calcium in the small intestines. Vitamin K2 takes calcium from the blood and transports it to the bones and teeth. It also activates a protein that keeps calcium out of the arteries, joints, and other areas of the body where it shouldn’t be.

Vitamin K2 has many additional potential benefits, from supporting healthy blood sugar levels to improving wrinkles.

Animal fats are a great source of the MK4 version of vitamin K2. A different form of vitamin K2, called MK7, comes from bacteria in foods like cheese and fermented foods. People who cut fatty foods from their diet are at risk for a vitamin K2 deficiency.

Foods high in vitamin K2:
• Grass-fed butter and ghee
• Hard and soft cheeses
• Egg yolks
• Goose liver, chicken liver, and beef liver
• Hot dogs
• Salmon

If someone chooses to take a vitamin K2 supplement, they may want to consider the MK7 version. For every 10,000 IU of vitamin D3, I suggest taking 100 MCG of vitamin K2.

    Thank you, Dr. Berg. I appreciate this information very much. I have been dealing with osteoporosis for the past year. I have been on medications to treat my bone loss but ended up with some serious stomach issues. I have been taking D3 with K2 the mk7 version for years however still having osteoporosis. I can’t take calcium supplements because they end up like you mentioned in my blood and heart. I’m stummed as to know what to do. The supplements D3-k2 is 5000 to a 100mcg ratio I will up my D3 without the k2 and see what happens. Is there anything else you could recommend? I broke my ankle recently and believe it’s because of my osteoporosis. I really would appreciate your feedback 🙏

I may increase, especially if get toe or leg cramps). you also get D3 from fatty fish, cod liver oil, small amts from eggs, cheese and beef liver. I ran out of cod liver oil and am now just taking D3 5000 IU along with K2 100 mcg as menaquinone 7.

  5. @CA-nm7mb on December 18, 2023 at 1:58 pm

    It’s crazy because I was just researching vitamin K2 because my doctor recommended me taking K2 along with vitamin D3 because as a 40 year old male, I was diagnosed with osteopenia after my Dexa Bone Density scan was done.

    Very abnormal for a guy my age to even have mild bone loss, it’s mostly a woman’s issue especially older woman, and very old men. The reason why I believe I have some miles bone loss is because I believe I have Hyperparathyoridsim.

    My serum calcium levels have always been high, actually they are too elevated which is not normal. So even though I have very high calcium levels in my blood, like 10.5 and sometimes higher, I have bone loss. The only explanation for the high calcium is that one of my parathyroid glands has a tumor which is causing my body to suck excess amounts of calcium from my bones even though my PTH levels are normal.

    So for now before doing more testing on my parathyroid glands, and to help remove that excess calcium from my blood, and put it back into my bones where it belongs, is to start taking K2 on a daily basis.

    I have dealt with chronic fatigue for years and slow memory processing, brain fog, lack of energy, and I believe it all has to do with the elevated calcium levels in my blood which can cause brain and nerve connection problems.

    In many ways vitamin K2 should be way more popular and talked about when it comes to cardiovascular health from cardiologist. If one has high blood pressure, some plaquing of the arteries already, cardiologist should start telling their patients to get on a vitamin K2 supplement ASAP, and not a stupid statin. K2 will help remove the plaque buildup in the arteries, unlike a statin or any other type of drug that doesn’t do a damn thing to actually fix or cure the problem.

    I am hoping after a few months of taking K2 and D3 together, that my serum calcium will go down into the 9’s where it should be, not in the 10’s especially the mid 10’s. Hopefully my energy levels, and cognitive function will improve even if I might possibly have a parathyroid tumor.
