1) Full disclosure: I haven't run blood tests to figure out exactly how much caffeine you absorb brushing with my toothpaste. Here's what I can tell you: in 1 ml of toothpaste there is just under 80 mg of caffeine. 1 ml is a bit more toothpaste than the pea-sized amount of toothpaste that you should use, but less than the amount you see put on a brush in a toothpaste commercial. You don't swallow toothpaste and brush for a brief period, so there is incomplete absorption. Based on the reported experiences of people who have used Power Toothpaste, it's faster acting, but say an hour later, it doesn't feel like you've had a full mug of coffee
2) (almost) immediate shipping. I have a few hundred units fully packed and ready to ship. I put a label on them and USPS picks them up! So it might be a day or two before it gets shipped. More inventory that needs to be packed before shipment.
3) Addressed this elsewhere in greater detail elsewhere, but as an adult you need less fluoride than children, and you may be getting fluoride in your water. I might suggest looking into a fluoridated mouthwash, sold at pretty much any pharmacy. I also don't reccomend Power Toothpaste before bed, so you might use a regular, fluoridated toothpaste :)
Thanks for all of the questions!
- femto 10y agoBy those numbers the 70 gram tube contains approximately 5-6 grams of caffeine? LD50 level for caffeine is estimated at 200mg/kg of body weight [2], so the tube could kill a 25kg person? I hope that the fresh minty taste isn't too attractive to children, as the lethal dose to a small child looks to be substantially less than one tube. By comparison, about two (100g?) tubes of fluoridated toothpaste could kill a 10kg (2yr old) child [2], so a child is unlikely to die from scoffing an open tube of toothpaste that they find in the house. Perhaps you should look at either the caffeine concentration or tube size, to ensure that an incidental poisoning can't occur due to a single open tube.

- schrodinger 10y agoIsn't caffeine a pretty strong acid? I'm really wondering if this is any good for your teeth.
- AstralStorm 10y agoIt is probably neutralised as otherwise the toothpaste wouldn't be effective. Increasing pH is one of the mechanisms killing bacteria and preventing decay.
