Vit D duration

[oily1601]

Hi all

Hope everyone is doing ok.I’ve been supplementing Vit d for approximately 5-6 months.Question is,how long should I leave it before testing,and do most people just keep supplementing anyway?

Cheers

I think you can just keep taking it. Are you doing blood testing for any other reason’s, if you are you can probably add it in. Check Dr Sarah Myhill’s website. I pretty sure she says it’s impossible to overdose. You should certainly carry on through the winter. Maybe check next summer?

No, you can reach toxic levels although thats highly unlikely unless dosing crazy amounts. Regular testing key.

You should test now or asap to see how well you are absorbing and avoid toxicity (which is unlikely unless youre taking extremely high doses). Test ~2 times/year although you may eventually be able to reduce if you notice stable serum figures e.g. plot on a graph. See a link below for target dose calculation etc if you dont have one.

Yes here in UK daily supplements needed (except if you manage to get outside on our relatively few sunny days) to maintain.

You can definately over dose on vit D so noooo don't just keep taking. You cannot excrete excess vit D. So if you were deficient you should retest after 3-6months of supplementing. If you are then optimal you may need an maintenance dose or you may need to top up periodically. Therefore test Vit D level annually after that. GP will check every two years for you.

What level would vitamin D toxicity be in the blood levels?

[waveylines in reply to HealthStarDust]

You should aim to stay in range. I aim towards the top of the range.

Ah. So near 150? Interesting when I have researched this I have not found a definitive answer. And, sometimes when I see people posts results, the company seem to suggest 70-250 is optimal like this person’s healthunlocked.com/thyroidu....

[waveylines in reply to HealthStarDust]

It depends on what vit D blood test you are using. Ranges can vary.

[Lynneypin]

I take it every day and retest every six months to make sure I’m at the right level.

[oily1601]

Thanks everyone for the advice….will get tested and go from there

Cheers

An overdose can feel like sunstroke, quite distinctive symptoms of nausea and dizzyness. Some people once optimised only take it in autumn and winter, topping up with natural sunlight (hopefully) in the summer !

How much vitamin D are you taking

What was vitamin D level when you started supplementing

Test twice year.

At last annually including folate, B12 and ferritin as well

When did you last test these?

GP should advise on self supplementing if over 50nmol, but under 75nmol (but they rarely do)

But with Hashimoto’s, improving to around 80nmol or 100nmol by self supplementing may be better

Once you Improve level, very likely you will need on going maintenance dose to keep it there.

Vitamin D mouth spray by Better You is very effective as it avoids poor gut function.

There’s a version made that also contains vitamin K2 Mk7.

One spray = 1000iu

I’ve tested regularly around every 2/3months to make sure my levels are where I want them, and any signs of vitamin d toxicity (although how we judge this is up for debate) especially as I started taking 4000ui per day. When my levels reached 100, I take the 4000ui every few days a week accounting for the fact that it’s winter now and there’s no sun to top it up.

Hope that helps.

As with all deficiencies, you'll have to test to see what you Vit D levels are before and after supplementation. "IF" you numbers keep dropping then you'll have to continue to take it. Getting to the ''real" root of why your body is potentially not holding onto it is the fun part..
