Your vitamin D level?

(B Creighton) #23

I take almost none during the summer, and 10,000 IUs in the winter - about 5 months where I live. That maintains a vit D level of about 60 in me. I think someone suggested also supplementing with vit K2. I have been doing that for 5 years now. Vit D is critical for liberating calcium in your system, and Vit K2 interacts with GLA matrix protein to make sure that calcium goes where you need it rather than into arthiritis. I take at least 100 mcg/day

Your body tries to make Vit D from cholesterol through sunshine on your skin. Some people have more difficulty with that genetically. If you get sun, and your D level is 28, you will require daily supplementation. Don’t worry about Calcifediol unless you are getting sick. It is true that Calciferol will take about 30 days to get converted for use in your immune system, but calcifediol is basically considered prescription here in the states. I have ordered it from Canada though. It is too expensive for daily use. I keep it in case my wife is getting sick because she tends not to supplement calciferol on a daily basis…

I take my Vitamin D and K2 pretty seriously. Honestly, much of the stuff you guys talk about (various measurement and tests) I have no idea of.

I take a K2 that has both MK4 and MK7. Also, many don’t realize there are “trans” and “cis” forms of K-2. Most are “cis” but the “trans” ones are better. Go ahead and search: “K2, trans vs cis” and probably you’ll learn all about it. I know it’s always something but if you take K2 you probably want to know this.

I take this one. Though there is also an Innovix brand which I sometimes take and its good too.

Vitamin K2, specifically the MK-7 form, exists in two primary isomeric configurations: trans and cis. The trans isomer is the naturally occurring, biologically active form that is essential for activating vitamin K-dependent proteins (VKDPs), which play critical roles in bone mineralization and preventing vascular calcification.35 The trans configuration features a linear structure that allows it to fit properly into the binding sites of enzymes like γ-glutamylcarboxylase (GGCX), which is necessary for the carboxylation and activation of VKDPs.36 In contrast, the cis isomer has a kinked or distorted structure due to its different geometric arrangement, which prevents it from effectively binding to these enzymes, rendering it largely inactive.

Also - and sorry but this is important. Most K2 sold is cis. If your K2 doesn’t specifically say “trans” or “bioactive” then it is cis. If its cis, then its not doing what you think its doing.

In this case trans is good.

I did not know that about vitamin K. Reminder to self: eat some natto that you made and that’s hiding in the fridge.

Well, I took a weekly Calcifediol (supposed to take once per week) and also took 15-20,000 IU of D3 every week (5000Iu capsules, 3-4 times per week) for a month, and went from 28 to 39. Not that large of an increase.

So, I may have to up my D3 intake to 10,000 IU, and try that basically daily.

My recent VitD level was 110. Yo!! I now very rarely get sick. When I do feel not great it usually lasts only a day or 2, and it is very mild. The body’s immune system working as it should.

Mine was 32 or so last Oct 1st. I’m requesting another test this Tuesday.

Have no idea what is in my system. I take 10,000 units of D3 and 100mcg of K2 daily

#32

My Vitamin D level was 80 in October, which is Spring here. Like @Alecmcq I live in a sunny part of Australia. Even winter is sunny.

I think that chronically low VitD levels is one of the most important hidden “pandemics” that exist in the world right now (along with diabetes, autoimmune diseases, and obesity… although obesity is hardly “hidden”!!).

I think it is worth almost overdosing on VitD, especially if you don’t see much sun exposure. Sunbathing is horribly unfashionable right now, but a judicious amount of sunbathing is IMHO incredibly healthy in ways we hardly understand… and it is not just VitD… I reckon there are many benefits of being in the sun that we don’t appreciate (yet).

Was actually 33 October 1st. Today it’s 40 per lb yesterday’s test result.

Guess I can go up to 6000-8000 per day and see how it goes. Perhaps 10000.
