Is there such a thing as a K2 to calcium ratio?

For example, if one drinks 52oz of Fairlife skim milk daily to meet their protein and nutrient requirement, this is about 3000mg of calcium a day.

Would 100ug and 2mg of MK4 daily provide the same benefit of putting calcium in the right places? Or is the higher dose needed with higher calcium?

I don't know of any basis to suggest a ratio is important.

no one researched the half life of diffent K2 forms?

Like MK4 has a short half life in the body. Like around 10hrs after ingesting not much is left.

Chris, have you seen SuperK by Life Extension? K1: 1,500mcg K2MK4: 1,000mcg K2MK7: 100mcg The add ons are not fantastic, though. Any thoughts? Thanks!

Yes, I think the doses are too high for most people.

Cold pressed canola oil has slightly less oleic acid than high oleic sunflower and safflower, but a 2 to 1 omega 6 to omega 3 ratio. High oleic sunflower and safflower have negligible omega 3, and thus a very poor 6/3 ratio.

Hi Chris, what are the effects of vitamin K2 supplementation on someone with high Lp(a)? Thank you.

I don’t see how they are related.

High Lp(a) has been linked with blood clotting. I've been recommending lumbrokinase for the clot factor (and diet + time-released nicotinic acid for the Lp(a)), but I know some doctors recommend aspirin or an anti-coagulant. You discouraged K2 supplement for people on a blood thinner. If they're not on a blood thinner per se but have clotting potential due to the Lp(a), what would be your thoughts on that? Educationally speaking. Thanks.

There are some people who get heart palpitations when taking K2. Do you have any information on this (why K2 causes palpitations and what can be done to prevent it)?
