B12 Supplement Question

Hi, I just wanted to ask a question. I plan to continue with a maintenance dose of at least 5,000 B12 a week. It is cheaper for me to take two 2500mg sublinguals a week rather than at least 5 1000mgs. Is there any difference in the efficiency? Thanks.

I would ask the question over on the Pernicious Anameia Society forum.

With oral tablets, I think it would make a difference.

You'd need to do some price comparisons to know that. I've not seen any 2500mcg ones, only 5000, 1000 and 500, but that doesn't mean they don't exist.

I prefer to take 1000mcg x 5 days a week, but that's just my preference as I want to take my B Complex those days as well.

Why 5 days, Susie?

BadHare Because my B12 got up to 1145 when supplementing 7 days a week, so as I want to keep it around the 900-1000 I've just dropped it to 5 days.

Ah, that makes sense, thanks Susie!

Check the prices on Amazon. They have a full range of brands and dosages.

FYI I use solgar 5000mcg methylcobalimin sublinguals and just ordered 2 x 60 for £22.95

before supplementing - are you experiencing symptoms of B12 deficiency?

Please take a look at the PAS forum as suggested by helvella

My B12 levels were barely in range last summer and since then as I first supplemented 5000 daily and then 1000 daily, the last two tests have seen my B12 above the range >1476. So as I continue to find the correct thyroid hormone dosage I'd like to have a maintenance dose for the B12.

suggest that you look at and join the PAS forum if you have concerns about B12 - as it is all about B12 deficiency.

Being 'barely in range' doesn't necessarily mean that you were deficient - 5% of people are actually perfectly okay with levels lower than the bottom of the range - back to serum B12 not being a test that can be used as a single indicator. If you have a B12 absorption problem supplementing at the levels you are currently supplementing is going to make getting a diagnosis impossible - take a look at the pinned posts on the PAS forum

I take B12 & Bs daily as they're water soluble, so won't build up in the body.

We can store fat soluble vitamins such as D, but not water soluble as excess is excreted.

Not what you're looking for?
