The pills are definitely small and red. I am currently using 1000 mcg once or twice a month. I was taking 5000 mcg once a week, which gave me insomnia and prostate pain. High levels of B12 apparently increases prostate cancer risk. Without blood tests, it's hard to know the right dose. These are very low in sugar. The bottle has a screw cap with cardboard in the cap. There is an absorbent in the bottle. It was messy opening the bottle - the cotton piece pulled out a few pills and red dust got all over the bottle. The foil seal peels off fairly clean with no sticky residue. I might try capsules next time, since I don't think sublingual tablets are necessary for most people.
