Most people--
 

--also take a B-complex (which may have some B12 in it), but take it at a different time of day than they take their megadose of B12.

Can some one please recommend a suitable B complex. Is this completely safe. I've had so many problems with medications in the past. I'm terrified.

I've often used--
 

--The Swanson in house brand, which is a B-complex with reasonably high, but not enormous amounts of the B-vitamins.

It comes in capsule form, and in varieties both with 500mg of Vitamin C or without.

I have noticed it does tend to make one's urine quite golden--the body does not tend to store B-vitamins that are not used immediately metabolically, and excretes them--but that is not much of a worrisome side effect. And it does seem to help me with overall energy.

The brands I like are Thorne Research, Jarrow and Life Extension. They make a B complex with the bio-available forms of B12, Folate and B6. Thorne has different variations of their complex. An example would be the one where the B12 contains two different bio-available forms of B12. Thorne tends to be more expensive of the three.

Hi. Thanks everyone. I have started a B12 supplement. In my recent blood test I had a red blood cell count over the top of the range at 6.3. It usually sits at 5.7-6.0. Is this still ok to take b12 with my RBC at this level.

Also I realised our b12 is measured in different units to the U.S.. My US equivalent is about 380.

Anthony,

I would not stop the B12 based on your RBC. IMO, your B12 at 380 is in the lower range so I would continue. Regarding blood counts, it's best not to rely on just one test and only one aspect of your CBC. That small rise could easily be attributed to how much or how little you hydrated before your test. If you are dehydrated then there is usually a higher concentration of RBCs when they check. Your doc would be looking at the CBC results and any symptoms you are having versus just a lab result. If you are concerned, then have them check again and watch for trends.

Also, it's best to stop your B12 supplements a few days prior to testing otherwise your B12 serum result could be falsely elevated.
