K2 dosage

[Suzan62]

I take accrete D3 twice daily and have been taking one Vitamin K2 (90 ug) per day. Just wondering if this is enough? It says to take 1-2 a day on the box.

It seems unclear but the few references we have been able to find suggest 180-200mcg a day.

[Suzan62 in reply to PMRpro]

Ah right, maybe I should be taking 2 then. Not sure how much I’m getting from food though so it’s a hard one to decide.

[PMRpro Ambassador in reply to Suzan62]

Probably not a lot unless you eat kimchi or natto which is unusual in the west.

[Suzan62 in reply to PMRpro]

No I don’t eat that so I’ll take 2 - 90 ug. There doesn’t seem to be any side effects if you do have too much K2 from what I can see.

Not sure that’s guaranteed - and it probably depends on how much is too much… 😏

[Suzan62 in reply to DorsetLady]

True and since writing that I’ve read about possible side effects so I’ll stick to the one or find some with a bit more than 90 ug per capsule and just take the one.

For several years I have taken gelcaps Vit K2 120 mcg and Vit D3 1,000 IU combined. Easily found in pharmacies here ( Canada) Worth looking for where you live , perhaps ?

Melio guide says “Vitamin K2 MK7 dosage recommendation is 150 to 180 µg per day. This is based on the dosage used in most recent research studies.”

I take roughly 120-140 a day but also have kefir which contains some and your body will convert some vitamin K in leafy greens for example to K2 although how much is anyone’s guess.

Thought this was an interesting recent, mainstream, article from Dublin university

This is really interesting. Thank you for raising it.My Vitamin K2 supplement (from Healthspan) is 75µg and recommended dose is 1 per day but perhaps I should be taking 2 alongside my Adcal-D3. Though it does say "do not exceed the recommended dose". 🙂

[DorsetLady PMRGCAuk volunteer in reply to Positive__]

Mine is 100mcg - and says the same!

[Positive__ in reply to DorsetLady]

Please can I ask - do you take 1 or 2 a day? 🙂

[DorsetLady PMRGCAuk volunteer in reply to Positive__]

I just take one - always have. And the comment re not exceeding recommended dose is on everything nowadays - but that doesn’t make it any easier if there no accurate figure for what is daily dose, does it? 🤦🏻‍♀️

[Positive__ in reply to DorsetLady]

Thank You, perhaps I'll stick at just one too then. 🙂I'm a bit freaked out at having the Dexa scan showing Osteoporosis at the start of the steroid journey but keep thinking actually I'm very fortunate the osteoporosis has been discovered. If I hadn't had Polymyalgia Rheumatica I would not have had a DEXA scan at age 56.

So with the Adcal-D3, Vitamin K2 and the weekly Alendronic Acid (as well as lots of spinach, sardines, yoghurt etc - all of which I love eating) I feel I am helping. 🙂

Agree, you are doing all you can.. and yes if weren’t made aware of osteoporosis it could have been a lot worse down the line.
