Coffee drinkers may be getting more than an energy boost. A Finnish study found that people who drank more coffee tended to have less total and abdominal fat, more muscle, and healthier metabolic markers despite having similar BMIs. Higher coffee intake was also linked to lower levels of certain amino acids associated with insulin resistance and type 2 diabetes risk.
I was trying to find out why caffeine anhydrous is so much cheaper per serving than a cup of coffee or tea when the source is coffee or tea. My only conclusion is they must use un-saleable types of coffee beans and tea leaves for caffeine extraction. Anyway, DIY energy drinks are stupendous, I can’t countenance paying so much for a can. What’s your preferred carbonation method, a Soda Stream or similar?
In fact, that’s natural caffeine since it comes from the bean or leaf; I use synthetic, which is derived by reacting urea and chloroacetic acid into barbituric acid, from there into theophylline by reacting with dimethylurea and formaldehyde, and finally methylated to get something chemically almost identical to pure caffeine:
I started with the synthetic because I wanted to observe the effects alone, and with l-theanine added; I didn’t want other compounds along for the ride and polluting my results. Natural is much more expensive, too; I find synthetic plus theanine sufficient. For carbon dioxide refills, there’s a guy in my area who exchanges the gas bottles and refills them himself. You could see if you have anyone like that nearby, or, often paintball shops and sports shops that sells paintball gear will be able to refill your cannisters for you.
Carbonator is a “drink mate” - unique from sodastream in that it can carbonate other liquids, not just water, without messing up the mechanism. Of course, I pretty much only carbonate water with it anyway… I’m certainly not gonna try it with milk! (jokes aside I have done juice, that was pretty cool)
