Supplements query

Hi, I have Hashimoto's and I would like advice regarding some supplements I want to take and if it's a good idea to take them now. The only reason I ask is really because my 6-week thyroid blood test is in two weeks' time and as I haven't taken any supplements since being on the 50mcg Levothyroxine I'm worried that by taking the supplements now the results of my thyroid blood test may be skewed.

I was already found to have low ferritin at 28 (30-400), Vitamin D at 73 (>75), folate at 4.9 (4.6-18.7) and Vitamin B12 at 362 (180-900)

Here are the supplements I am looking to include as part of my daily routine:

Iron (liquid) - 2x 10ml dose per day. Iron: 19.2mg, Vitamin C: 20mg, Thiamin: 1.72mg, Riboflavin: 1.72mg, Vitamin B6: 1.72mg, Vitamin B12: 1.72mg

Multivitamin (effervescent tablet) - 1 per day. Vitamin C: 1000mg, Vitamin A: 700ug, Vitamin D: 10ug, Vitamin E: 45mg, Vitamin B6: 6.5mg, Vitamin B12: 9.6ug, Folic acid: 400ug, Zinc: 10mg, Iron: 5mg, Copper: 0.9mg, Selenium: 110ug

Multivitamin (chewable lozenge) - 1 per day. Vitamin A: 800ug, Vitamin C: 80mg, Vitamin D3: 5ug, Vitamin E: 12mg, Vitamin B2: 1.4mg, Vitamin B5: 6mg, Vitamin B6: 1.4mg, Flaxseed oil: 380mg, Omega-3: 171mg

Multivitamin (chewable lozenge) - 1 per day. Vitamin B2: 1.4mg, Vitamin B5: 6mg, Vitamin B6: 1.4mg, Vitamin B12: 2.5ug, Vitamin C: 80mg, Vitamin E: 12mg.

If the best thing for me to do is to hold off until the blood test is done that's fine but I'm just wondering if by taking the supplements 2 weeks before my blood test might skew the results.

Thanks!

Most iron supplements will constipate, unless it specifies on the package that it's non-constipating.

It looks like the only things you wouldn't be getting at least 100% of with the effervescent tablet (and some more than 1000% of) is the iron and copper and the others don't even mention those anyway.  In that case, 3 multi's just seem like a bit of overkill, not to mention unnecessary expense.

Some of us need extra calcium to prevent osteoporosis, some don't. I happen to be one that does.  Vitamin D is  necessary for the absorption of calcium (most multi's have some calcium), as is magnesium, which I also take separately.

If I have the chvostek sign then I know I need more vitamin D (needed to absorb calcium). I have enough calcium in my diet.  There is demo on youtube if you want to check it out: Positive Chvostek Sign showing Low Calcium Levels.

Thanks for your reply.

I was planning on adding 3 multivitamins because not all of them contain the same ones. Also I was under the impression that the RDA% is for those without autoimmune problems so I might have gotten this wrong.

I don't know if the iron is a non-constipating type or not. It's had good reviews and the reviews don't seem to mention constipation so maybe it's okay.

Multivitamin (effervescent tablet) - RDAs are:

Vitamin C - 1250%
Vitamin A - 87.5%
Vitamin D - 200%
Vitamin E - 375%
Vitamin B6 - 464%
Vitamin B12 - 384%
Folic acid - 200%
Zinc - 100%
Iron - 36%
Copper - 90%
Selenium - 200%

Multivitamin (chewable lozenge)
Vitamin A - 100%
Vitamin C - 100%
Vitamin D3 - 100%
Vitamin E - 100%
Vitamin B2 - 100%
Vitamin B5 - 100%
Vitamin B6 - 100%
Flaxseed oil - N/A
Omega-3 - N/A

Multivitamin (chewable lozenge)
Vitamin B2 - 100%
Vitamin B5 - 100%
Vitamin B6 - 100%
Vitamin B12 - 100%
Vitamin C - 100%
Vitamin E - 100%

Would I be likely to need a calcium supplement even though my blood results for that were normal? The levels were:

Serum calcium - 2.32 (2.20-2.60)
Corrected serum calcium level - 2.30 (2.20-2.60)

Why are you planning to add 3 multivitamins?  The amounts shown in the multi's don't look like what we, typically, see; what's the percentage of daily value in each one?  I find that taking the individual vitamins I need, works better than a multi.   For instance, I take vitamin D - 2000 IU/day, selenium - 200 mcg/day, calcium - 600 mg X 2/day, B-12 - 1000 mcg X 1 injection/week, etc.

Taking vitamins isn't really going to skew your thyroid tests.  Ferritin has been shown to be instrumental in helping with conversion of FT4 to FT3, but with only 2 weeks before your blood work, I doubt there will be that much difference if you start taking iron now.  

Make sure your iron is a non-constipating type.

All vitamins/minerals should be taken at least 4 hours from any thyroid medication as they can inhibit absorption of thyroid medication.
