As a lot of you will know, many companies bulk up their capsules with fillers. And, let's be honest, who wants this? Nobody.These capsules, according to the packaging, contain taurine powder and nothing more, so that's already a positive!You also get a high amount of taurine in one capsule. This is excellent as too often a company will market their product as offering, for example, 1000 mg of taurine. But when you look closely, you realise it takes two capsules to attain that dose. Not so with this company.Most importantly, I can tell when I've taken these taurine capsules. They help keep my heart calm and reduce my anxiety. This is especially helpful for those days that you take a little too much coffee. They also appear to increase my energy levels during the day, while helping me obtain a deeper sleep at night. I say "appear" as the placebo effect could be at play; but even if it is, it's working!All in all, my experience has been positive.
