I had my B-12 blood level checked by my physician because I wanted to know the efficacy of the Sam's B-12 I was taking. My level was excellent and it makes me feel confident that the medication contains what it says on the label. Immune systems need to be top notch in today's world.

I normally take 2500mcg. One tablet every 12 hrs is generally recommended per day. 5000mcg is the very max that should be taken within a 24hr period. I've never taken 5000mcg in one tablet before. Will one tablet of 5000mcg cover me all day? I don't know.

I would not take this ever again and decided to just get my Vitamin B12 from eggs Egglands Best People wake up, I realized these vitamins are not FDA approved and they can put stuff in there to kill you. Read the first two ingredients. Microcrystalline cellulose is a term for refined wood pulp and is used as a texturizer, an anti-caking agent, a fat substitute, an emulsifier, an extender, and a bulking agent in food production. The most common form is used in vitamins. Adverse reactions more commonly reported during or after the infusion of mannitol (mannitol (mannitol injection) injection) include: Pulmonary congestion, fluid and electrolyte imbalance, acidosis, electrolyte loss, dryness of mouth, thirst, marked diuresis, urinary retention, edema, headache, blurred vision. This is pure crazy!! If you can’t pronounce the words or they are very complicated words you don’t know what they mean. Don’t take the drug.
