I see that the source of K2 is mk-4 but how is it derived? Soy, natto, chickpeas??

I wondered too because the picture showing the ingredients mysteriously cut off what type of menaquinone it is. I learned it contains menaquinone-4, aka mk-4, or menatetrenone. There was no info regarding its source. In fact, although the product description here fully explains its source of vitamin D3, it omits saying anything about their K2 source. I found this as odd as the ingredients picture, and it was only for this reason that I decided I'd better check. Menaquinone-7 (mk-7) is the long-chain version (menaquinone-4 is short-chain) and it's generally accepted as a superb source, often derived from fermented natto. Even though natto is made from soybeans, by the time mk-7 is synthesized from this, realistically, no soy remains. This is from an NCBI study: "The current study shows that MK-4 has a poor bioavailability at a nutritional level dose, whereas MK-7 is well absorbed and detectable in the blood at nutritional levels. " I am so surprised Seeking Health is not using mk-7. They're usually a trusted manufacturer for me, but not in this instance. Be sure to check the type of K2 in whatever supplement you get because there are also synthetic forms that should be avoided. Anyway, it's good someone questioned this, and I almost missed it completely by assuming Seeking Health would use only the best sources. 🤷♂️ It pays to check every detail.

Is this supposed to have a bitter taste?

I love Seeking Health however the vitamin D3 K2 is terrible tasting.. Yes it’s bitter. I believe it’s the olive oil they use. Very bitter and makes my throat burn. I switched to Thorn Vit D3 K2 and have not had the same issue. Hope that answers your question.

What is the source of the K2 in this supplement ?

Seeking Health has a D3 with K2 now in pill form. It states 100 mcg of K2 (as menaquinone-7). The liquid bottle just lists K2 and has no other source listed on the label.

Is this product gluten-free? I know it doesn't contain any gluten ingredients, but is cross contamination a possibility?

We have gluten issues in our home and I have not seen a reaction. Unfortunately I’m just a customer so I can’t say what their practices are to prevent cross contamination, if any.

Because that’s the carrier instead of ubiquitous seed/vegetable oils. This product is the only D3 K2 I could find that didn’t have inflammatory oils or fillers. It comes in a dropper bottle. We keep it in the fridge to prevent the olive oil from going rancid. This means we have to leave it on the counter or warm it in our hands to melt the oil. Seems to work and is easy to take.
