What is the significance of "12.5". Is this your level? If so what is the unit of measurement - nmol/L or ng/ml?

Do you have Hashi's?

Total vit.D 55nmo1/L (50-75) = 22ng/ml

The Vit D Council recommends a level of 125nmol/L (50ng/ml) and the Vit D Society recommends a level of 100-150nmol/L (40-60ng/ml).

To reach the recommended level from your current level, based on the Vit D Council's suggestions you could supplement with 3,700iu D3 daily (nearest is 4,000iu)

vitamindcouncil.org/i-teste...

Retest after 3 months.

I don't think you've bought 12.5mg D3. It comes in mcg (micrograms) or International Units (IU).

If you've bought 12.5mcg then that is 500iu and that is a very low dose, the sort of thing they'd sell in a supermarket. It will be totally useless in your situation.

As you have Hashi's, then for best absorption an oral spray is recommended (eg BetterYou) or sublingual liquid. These are absorbed through the mucous membranes in the oral cavity so bypass the stomach.

When you've reached the recommended level then you'll need a maintenance dose to keep it there, which may be 2000iu daily, maybe more or less, maybe less in summer than winter, it's trial and error so it's recommended to retest once or twice a year to keep within the recommended range. You can do this with a private fingerprick blood spot test with an NHS lab which offers this test to the general public:

vitamindtest.org.uk/

There are important cofactors needed when taking D3 as recommended by the Vit D Council

vitamindcouncil.org/about-v...

D3 aids absorption of calcium from food and K2-MK7 directs the calcium to bones and teeth where it is needed and away from arteries and soft tissues where it can be deposited and cause problems such as hardening of the arteries, kidney stones, etc.

D3 and K2 are fat soluble so should be taken with the fattiest meal of the day, D3 four hours away from thyroid meds if taking tablets/capsules/softgels, no necessity if using an oral spray

Magnesium helps D3 to work. We need Magnesium so that the body utilises D3, it's required to convert Vit D into it's active form. So it's important we ensure we take magnesium when supplementing with D3.

Magnesium comes in different forms, check to see which would suit you best and as it's calming it's best taken in the evening, four hours away from thyroid meds if taking tablets/capsules, no necessity if using topical forms of magnesium.

Check out the other cofactors too (some of which can be obtained from food).

Hi - I also have a Vit D question. My result was 29, the range is 30-100 ng/ml. My dr said take 2000 iu. It that appropriate or should I be taking more? Would it benefit being retested sooner than 3 months?

No it's not enough.

If you look at the link to the Vit D Council that I gave above, you will see that they recommend 3,700iu D3 daily levels between 20 and 30ng/ml (nearest is 4,000iu).

All the information given about cofactors, retesting and adjusting to a maintenance dose once the recommended level has been reached in my reply above to Gettingoldnow apply to you also.

Not much point in retesting sooner than 3 months.

Looking at previous posts you have Hashimoto's confirmed as cause of your hypothyroidism by high TPO antibodies

Low vitamin D, folate, ferritin and B12 are extremely common

Have folate, B12 and ferritin been tested?

GP will only prescribe to bring vitamin D up to 50nmol. Aiming to improve by self supplementing to at least 80nmol and around 100nmol may be better .

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

Retesting twice yearly via vitamindtest.org.uk

Vitamin D mouth spray by Better You is good as avoids poor gut function.

It's trial and error what dose each person needs.

Frequently with Hashimoto's we need higher dose than average to raise levels

IBS is often improved by strictly gluten free diet

Changing to a strictly gluten free diet may help reduce symptoms, help gut heal and slowly lower TPO antibodies

While still eating high gluten diet ask GP for coeliac blood test first or buy test online for under £20, just to rule it out first

Assuming test is negative you can immediately go on strictly gluten free diet

(If test is positive you will need to remain on high gluten diet until endoscopy, maximum 6 weeks wait officially)

Trying gluten free diet for 3-6 months. If no noticeable improvement then reintroduce gluten and see if symptoms get worse

Best vitamins to take are the ones that absorb better,that our bodies recognizes as food. These are “ Isotonix” brand. They are same as our body fluid like tears,sweat etc. They are absorbed within 5-7 minutes after taking them. Vitamin D is the most critical vitamin needed in the countries where we don’t have enough sun or it’s cold to go out in the sun.

Can you sunbathe a bit? No complications - just go in the shade after 20-30 mins.

If you can't manage that, try to build up 5-10 mins at a time :)
