Are there any adverse reactions i should be aware of taking 1000mg B12?

Question

Also is there some other supplement i should be taking to make sure my body absorbs the full amout or the most.

Answer 1

1 mcg = 0.001 milligrams buddy ... 1000mcg = 1mg ....1,000,000mcg = 1000mg ........ daily dosges most often used are 5 - 100mcg and the recommended adult daily dose is 2mcg ..............  1000mg per day will just give you really expensive peesh ............. The B complex of vitamins is essential for healthy neural, digestive and immune system functioning and helps you to better deal with the every day stresses of life ....... B12 is part of the B complex of vitamins and it is a water soluble complex hence, what the body doesn't use will simply be excreted in your urine ................Don't take any of the B complex of vitamins individually but rather as a whole complex as they work best synergistically (together) ........  get a liquid complex as it is the easiest for your body to assimilate ........  get one including all the B's ie ~ B1, B2, B3, B5, B6, B12 and folic acid etc...... B12 needs B6, calcium and vitamin D for effective assimilation by the body so pump up your intake of leafy and green vegies (calcium) and cold water fishes like salmon, sardines, whiting and tuna (calcium and vitamin D) .......  to get enough vitamin D on a daily basis all you need is 10 - 15 minutes of safe sun exposure .... vitamin D is known as the sunshine vitamin ......  if you choose to get a calcium supplement get one that contains vitamin D3 as D3 is the best form.

Answer 2

Your stomach should produce a substance called Intrinsic Factor that allows your intestines to absorb the vitamin B12.  Many people do not produce Intrinsic Factor on their own.  You can either take a B12 supplement that contains Intrinsic Factor, such as IntrinsiB12 by Metagenix, or you can take B12 sublingually (in a quick-dissolving tablet you hold under your tongue), or with a patch or a prescription injection, nasal spray, or gel.  These methods bypass the intestines.  There are different types of B12.  Methyl B12 is becoming more popular; it is the easiest for the body to utilize, however, some people cannot tolerate it.  Depending on your genetics, you may need a less broken-down form of B12 such as cynocobalamin or hydroxycobalamin (cobalamin is the name for vit. B12).  If your are an "over-methylator", you may get a headache from methyl B12 and therefore should try hydroxy B12 instead.
