How much vitamin b should i take?!


Question: How much vitamin b should i take.?
i have read on internet that Vit B is good for depression. however the recommended amounts online are a lot higher than what is available in the shops.
For example on line it says to take 25mcg of B12 but the shops only have 1mcg and pharmasist says it is dangerous to take more than that. I am confused as to how much to take to relieve depression. I feel i would be wasting my cash by buying from shops if level is too low to do any good. It is the same with other B vitamins as well, anyone tried this .?

Answers:
It sounds like there might be some misunderstanding in the dosages. 25 mcg is a very low dose of B-12... it's only about 4 times the RDA (which is VERY low for most B Vitamins) and a normal dose is 500-1,000 mcg, but is taken up to 5,000 mcg. Now, the misunderstanding may be that 1,000 mcg is the same as 1 mg. I can honestly say I've never seen less than a 6 mcg dose of B-12, and that was in a combination with a bunch of other nutrients.
No, it's not dangerous to take 1 mg (or even 5 mg) as long as you aren't allergic to it (which is rare), plus the fact that the B Vitamins are water-soluble, so your body will excrete what it can't use.
That all being said, B-12 is great for energy and mood among other things. Good luck!Health Question & Answer

i dont know the answer to your question but during a disatrous depression in the peri menopause i took the vitamin b complex - i am told that vitamin b6 is the womens vitamin for pmt etc., b6 and b12 re good for nerves - if yu cant get to grips witih the amount of supplements how about taking brewers yeast or eating the food with plenty vit b - try liver, porridge oats, spinach, do a google for vitamin b sources this will help. the amount of supplements has always caused confusion and its best to have a natural source if poss, magnesium ok is good too for depression a mix of vit b and magnesium good for pmt too. hope i have helped.Health Question & Answer

B helps with depression only in people who are depressed as a side effect of a B vitamin defeciency.... which is not that many people.Health Question & Answer

First you must consider how much B vitamins you are absorbing. A healthy gut is required for the absorption of (absorbable) vitamins and minerals. With healthy gut integrity and a healthy diet (whole organic: meat, vegetables, fruits, nuts, grains) you should be getting all the B vitamins you need.

Certain pathologies can block the absorption of vitamins. An example is malabsorption of vitamin B12 due to autoantibodies to parietal cells in your stomach. Parietal cells secrete intrinsic factor which is needed for the absorption of B12 in the distal ilium (sm. intestine). The result of this pathology is pernicious anemia.

If your doctor finds that you have deficiencies in B vitamins he/she may prescribe therapeutic doses (TD). The following is for your information and is not a recommendation. Ask your doctor before taking any of the following TDs.
