Superior Source Vitamin K2 MK-4 500 mcg, 60 Quick Dissolve MicroLingual Tablets, Supports Bones, Arteries, Immune & Cardiovascular Health, Non-GMO

Vitamin K2, taken sublingually, was a revelation for my health. Dealing with IBS often meant that my bone health was a concern due to malabsorption issues. K2 played a crucial role in calcium metabolism, directing calcium to my bones where it's needed, rather than depositing it in arteries. This not only helped in potentially reducing my risk of heart disease but also supported my bone density, an essential factor for my long-term health.

I recently tried Swanson's Natural Vitamin K2 in the form of 30 softgels, each containing 50 mcg. Swanson's Natural Vitamin K2 has been a game-changer for me. Easy to take, and I've noticed improved bone health and overall well-being. Highly recommend!

...but I gave them anyway, for the following reason: The instructions for the Now Foods Calcium and Magnesium advise also taking this, presumably for the following reason: Vit K makes the calcium go to your bones and not your arteries. I've gotten fabulous results from the "reverse" magnesium and calcium, so I gave both it and the K2 five stars.

I prefer to take sublinguals and this product is very good. I have not taken long enough to notice any difference yet, but I am hopeful. The quality is very good. The sublingual dissolves very quickly and the taste is pleasant. I have used other Superior Source products before and this one doesn't disappoint.

immediate benefit, amazing product. dissolves instantly! no artificial added ingredients and it tastes good. excellent for people like me who have problems absorbing fat soluble vitamins. mk-4 does not give me adverse reactions that i experrience with mk-7 form of k2

While I generally use both forms of K2 (Mk-4 and MK-7), I need more help with bone building, which is what this form is most helpful for, according to clinical studies. It's a small, quick dissolving tablet that can be swallowed whole, chewed, or dissolved under the tongue. The taste is pleasant and it generally dissolves in the mouth within 30 seconds. I chose this brand specifically because they offered a lower (500 mcg) dose that can be taken in divided doses. Research suggests MK-4 doesn't stay active in the blood for long, so I generally take 2 a day.

Great product. The only thing I don't like is that it is only a two month supply. I was using another product before which was just as good, but I got 90 tablets for less money. I cannot find that product anymore so was forced to switch. I am happy with this brand in every other way. Dissolves quickly. Taste fine. I think taking vitamin K has helped improve my recent bone scan numbers. It is a must have for me.

K2 is recommended to help taxi calcium out of the arteries where it shouldn't be and into your bones. Have been taking for several years along with d and magnesium with no complaints. No obvious effect , so it's hard to know if its working-but like that it's sublingual and especially that it's the mk-4 form of k2.

Decent option for MK-4 variant of vitamin K2. Supplements of this type are rare and either contain too small of a dose to even matter or come in big packages at high prices like Thorne K2 product or in combination supplements with K1 and MK-7. This one comes at 500 mg tablets of MK-4 only which for K2 is rather low dosage but sublingual route may increase its bioavailability. Acacia gum may be problematic additive though.

Tried this K2 MK4 in isolation for 7 days. Intense pain around neck/ear/chest and raised blood pressure. Had to throw it in garbage. Then I tried K2 MK7 in isolation for 15 days. Had the reverse but desired effect. The pain around neck/ ears/ chest eased up considerably and it appears it had a blood thinning effect. Now I realize why I was reacting badly to my multi which had k2 mk4 and k1 in addition to k2 mk7. Since them I am stocking to Only k2 mk7 in isolation without mixing it up with k2vmk4 or k1!!
