Quality is good, ingredients are helpful, size is enough, composition are good
I love this stuff. So good. Helps with energy, focus, makes you feel calm and alert. I take one every day. Sometimes two. On an empty stomach in the morning. Gives me a good boost with no crash. Better than coffee in my opinion. Good for adhd if you want natural options
I have HPA dysfunction, (Hypothalamus, pituitary, adrenal axis) Diagnosed by saliva testing. Cortisol is too high in morning and during the day, going down to normal late afternoon, then spiking in the middle of the night, with awakening then and early morning awakening. I can get very tired during the day, even when clocking up enough hours of sleep. Mid morning, a few hours after getting up, I often get tired. I took 1 capsule with a glass of milk at 11 a.m., but didn't feel more wake up at all. Tried again taking without and also before a meal, and my tiredness disappeared within about 20 minutes on both those days. Took again recently, not near food, and it didn't work. So not getting consistent results.
This is the Best Caffeine Theanine Blend ever! I've tried other brands to give my energy a boost. This works the best somehow even though the ingredients are the same. It is definitely quality and benefit me greatly on days I need to study. Don't worry about taste because there is not jarring aftertaste at all.
If you're looking for an energy boosting supplement then this is the perfect product for you, I sincerely thought that this is really the most effective energy supporting capsule here in the market, great for mental focus as it makes you lively and active the whole day, great quality product from iHerb!
