My wife suggested I used these as an alternative to energy drinks, I was sceptical about them being as effective as my favourite top brand daily energy drink. I have now been having 1 effervescent tablet a day in a litre bottle of water for a month now and I was shocked at how good it made me feel from day one. I’ve not drunk an otc energy drink since and haven’t missed them at all. Overall I’m feeling energised, focused and motivated throughout the entire day. They work out cheaper and are a lot healthier than what I was drinking. 10/10 from me 👍🏼
