The length of time for the expiration date or "best used before" date depends on the type of product, as well as the brand.
Perishable items (such as flax oils or certain probiotics) generally have shorter expiration dates. Although our warehouse is fully air-conditioned, these more fragile items are put in cold storage (freezer or refrigeration unit) for maximum freshness.
Our receiving department does its best to verify and then enter the correct expiration dates for all incoming products. However, discrepancies do occur from time to time. This being said, the exceptionally high turnover at iHerb ensures that our inventory is among the freshest in the industry.
Formerly Bioactive-B12
Are You Getting Enough B12?
Normally, vitamin B12 is easily attained from foods like fish, meat, poultry, eggs, and milk. But if you're a vegetarian or are unable to absorb B12 from food, you're likely not getting the amount you need, which can leave you feeling fatigued.
B12 Infusion uses the most natural, bio-identical form of vitamin B12, which is immediately available for use in the body and doesn't have to be converted first. One daily dose of B12 Infusion provides 1,000 micrograms of B12—a clinical dose that absorbs quickly to help keep you energized and kick fatigue...fast!
Recommendations: One tablet daily; chew and dissolve in the mouth before swallowing.

Not all methylcobalamin is the same, there are huge differences in potency and it's not about the mg's. This is the best B12 I've tried. Most sublingual methylcobalamin has no noticeable effect on me. (No B12 alleviates my tiredness, but good B12 products make me sleep deeper.) This works better for me than some 10 mg products. Combined with some adenosylcobalamin the effect is very noticeable. Just don't chew it, but place it under your tongue or lip for maximal absorption.

I've used a couple of brands of methyl-b12 and this on seems to work best for me. Don't know where I'd be without it (bed probably). Delivered on time and as described.

I have a mthfr gene mutation and was recommended to use this for energy. It is fantastic! At first I only had 1 tablet, but after reading other reviews, I space out between 1-4 tablets a day, depending on how I feel. I believe you're body can't absorb too much B12 at once, hence why I like to space it out. The tablets taste nice and are easy to chew/absorb via your mouth. I just wish they sold bigger bottles of it! I highly recommend it if you need methyl b12.

I take one pill a day in the morning with jarrows methyl B12 and it is definitely working. Gives me a lot of boost.

The is an easy way to get B12, but I did not feel any energy.
