Puritan's Pride says, Directions: For adults, take one (1) microlozenge daily, preferably with a meal. Place microlozenge under tongue for 30 seconds before swallowing.

I thought B12 should be taken on empty stomach?

Also, they cost $12.99 for 120 - 5mg or 0.22 per pill which is pretty good?

Jarrow Has Xylitol as the first other ingredient in it of which I am not a big fan.

Wow - Kirkland Signature™ Sublingual B-12 5000 mcg., 300 Tablets $19.99. We do not have a CostCo -- gotta see what it costs to order online.

BTW, I have been taking MetaNx daily. I was going to do the same with B12, but double the dose. However, you say you take it twice a week. Will I be over doing it?

Thanks.
