Oral methylcobalamin (and cyano) need to be taken on an empty stomach. Otherwise the micrograms are lost in food and not absorbed properly.
1000mcg of B12 yielded only 13mcg absorption into the blood stream in a trial that measured oral absorption. So taking less than 1000mcg may not yield much results.
You can now by methylcobalamin in stores, Costco and Walgreen's now sell it. iherb.com has several brands and so does
Amazon now.
