This has honestly provided me more focus and a feeling of alertness throughout the day. Most importantly in the morning. I was having a lot of brain fog, masking it with coffee and sleeping in wasn’t helping. This isn’t like a spark of energy thing, at least for me, but i feel more “up” and “awake” if that makes sense. No more brain fog and poor focus. Since I got my order, just now a week, I’ve been taking the Seamoss bitters and brain tonic as recommended and these will both be something l subscribe to. The results were fairly quick and noticeable. I’ve never had any issues with any products and the customer service is great, any issues get rectified quickly and it’s not uncommon to receive a free sample of something!
