Vit D should be 100-150nmol/L according to the Vit D Council. Continue with your spray until you reach that level, retest about April time, then you should find your maintenance dose. I don't tolerate the sun so I need to supplement all year round.
When supplementing with D3 we need it's important cofactors vitamindcouncil.org/about-v... Magnesium helps D3 to work and K2-MK7 directs the extra uptake of calcium from food to bones and teeth where it is needed and away from arteries and soft tissues where it can be deposited and cause problems.
Zinc is a bit on the low side, Mine was low and I take a multi mineral which contains some zinc.
Ferritin is fine and you should maintain it at that level, easily done if you are a meat eater, liver occasionally will help.
Folate is good.
B12 is OKish although an extract from the book, "Could it be B12?" by Sally M. Pacholok:
"We believe that the 'normal' serum B12 threshold needs to be raised from 200 pg/ml to at least 450 pg/ml because deficiencies begin to appear in the cerebrospinal fluid below 550".
"For brain and nervous system health and prevention of disease in older adults, serum B12 levels should be maintained near or above 1000 pg/ml."
If you feel OK with those thyroid levels then your dose is fine. Your FT3 is a tad low and supplementing with selenium should help conversion of T4 to T3 so may bring your FT3 up enough to be in balance with FT4.
Yes that's fine, the normal dose in supplements is 90-100mcg and that is enough for up to 10,000iu D3.
Sorry I didn't see your other reply or I would have linked to a good one for you. One that is oil based is best as the oil aids absorption. I'm using this one bigvits.co.uk/product.php?p... Very good quality, nice small softgel, minimal ingredients and no nasty fillers, 6 months worth so a decent buy.
They are a lot cheaper in the US but of course I don't know if they are available over the counter. All the decent quality supplements here in the UK tend to be online rather than in walk-in health shops or pharmacies.
Would recommend a good vitamin B complex plus sublingual B12 lozenge daily to improve both B12 and all the B vitamins
If you are taking vitamin B complex, or any supplements containing biotin, remember to stop these 3-5 days before any blood tests, as biotin can falsely affect test results
