I understand you are hesitant to consume GMO's. The part of the soy that is modified is the part that makes certain proteins in the plant. This vitamin is extracted from the natto and the questionable proteins are left behind. I've been taking this vitamin for years.

Soy has several issues unrelated to the GMO. I don't consume it regardless of whether it is GMO.

Good Luck,

  Hi Vanessa H,
I already discarded the bottle of Vit K2, so I cannot be sure that the soy component is organic. However, I have bought many Vitaming Shoppe products over several years and so far none of them contained GMO components.

  That's a good question! I don't know the answer to that but I would guess that if it is not listed as organic, you can assume it is not. Being organic is a good selling point and I assume it would be labeled if it was. Vitamin K2 doesn't have to be made from the fermentation of soybeans. There are two types of K2 and both are very good for you. I have made the switch from the fermented form (MK-7) to the fat-soluble form (MK-4) which is made from animal fats. I don't digest anything fermented very well and there is also the GMO concern that you raised which is why I made the switch. And of course there is K1, which is from plant sources. It is also good but maybe a little harder for the body to convert. Carlson's makes the MK-4 version. Don't be alarmed by the higher dosage (5mg) because this form of K2 requires this. It is a safe dose to take.

  How many micrograms does this contain?

  If Taking a Vitamin D Supplement, Remember K2 and Magnesium, Too -

If you opt for a supplement, be sure to take vitamin D3—not synthetic D2—and take vitamin K2 and magnesium in conjunction with it. Vitamin D is fat-soluble, so taking some form of healthy fat with it will also help optimize absorption. The biological role of vitamin K2 is to help move calcium into the proper areas in your body, and without sufficient amounts, calcium may build up in areas such as your arteries and soft tissues. This can cause calcification that can lead to hardening of your arteries—a side effect previously thought to be caused by vitamin D toxicity. We now know that inappropriate calcification is actually due more to lack of K2 than simply too much vitamin D.

Magnesium is also important, both for the proper function of calcium, and for the activity of vitamin D as it converts vitamin D into its active form. Magnesium also activates enzyme activity that helps your body use the vitamin D. In fact, all enzymes that metabolize vitamin D require magnesium to work. As with vitamin D and K2, magnesium deficiency is also common, and if you’re lacking in magnesium and take supplemental calcium, you may exacerbate the situation.

Vitamin A, zinc, and boron are other important cofactors that interact with vitamin D. When taking supplements, it can be easy to create lopsided ratios, so getting these nutrients from an organic whole food diet and sensible sun exposure is generally your best bet. Dietary sources of magnesium include sea vegetables, such as kelp, dulse, and nori. Vegetables can also be a good source. As for supplements, magnesium citrate and magnesium threonate are among the best.

  I have been taking K2 for years. I take it, and other supplements, for my bones. I have not had any side effects. I am 90 years old, and I have not broken any bones. I have not noticed any changes in my teeth.

  I have not noticed any side effects from this product. I purchased it to combat osteoporsis. I don't know if it had any effect on that condition.

  Ordered it for a friend so have no information on what it does. Sorry

  To my knowledge, yes you can take K2 with other vitamins. It's often included in multivitamin formulas, but at a lower dose. This form, VITAMIN K2(AS MENAQUINONE 7)is probably the most bioactive. K2 controls blood clotting, but that affect doesn't increase with dose. Also important, K2 encourages the deposition of calcium into the bones, and not the arteries, where it may contribute to atherosclerosis. However, don't take k2 if you're taking prescription blood thinners like koumadin or warfarin without consulting your physician..

  My physician asks that I take K-2, D-3, B-complex and fish oil. I take them all together after my evening meal and have had no issues. My physician has no problem with my routine, so I can only assume it is okay. I can't answer if you are asking about any other vitamins or medications. Probably best to check with your doctor.

  Yes, but if you are taking it with a multivitamin,
make sure you are not exceeding your limit.

  Yes. It works best when taken with D3.

  Don't know if it is or not, since that's not an issue for me. Sorry that I can't help with your question.

  No, but usually vitamin k-2 is derived from Natto, a fermented soy product that is totally vegan.

  The container says so.

  Yes, it's vegan.

  I take 400 IU of D3 in Summer and double up on that in the Winter. My multivitamin contains 300mg calcium and 100mg magnesium - on the advice of my doctors I discontinued taking an additional calcium supplement. However I take the K2 as it is supposed to enhance the absorption of calcium into the bones instead of the arteries.

  I think it's a personal choice I take the K2, 2000ui of D3 and one magnesium at bedtime

  The label does not say and until you asked this question, I hadn't realized it contained soy. Vitamin Shoppe, you need to address this question. And WHY is there soy in there?

  It doesn't say how much soy is in this product just that it has soy in it.
