Love the balance of calm focus from the L-theanine with a gentle caffeine kick. The added cocoa and matcha give it some extra balance Capsules are easy to take, and the energy boost is smooth without jitters. Great for morning productivity or afternoon pick-me-ups. I have it beside my bed so I can pop one in the morning if I'm feeling unmotivated.

I bought this as my mum recommended me to use it. It has lots of benefits for overall health support. The taste is ok. Good dosage, ingredients and the size are great. Good quality. I love this brand! I often buy their products and highly recommend them to everybody! They’re lovely.
My experience with California Gold Nutrition TheanineUP has been very positive. It has significantly helped reduce my stress levels and improve my focus, making my workdays more manageable and productive. I highly recommend it to anyone looking for a natural way to enhance mental clarity and calmness without any negative side effects.It is advisable to use it in the morning for the caffeine.
As a workout enthusiast, I take this as it has been shown to increase alertness and focus, dilates blood vessels for better blood flow, decreases the perception of fatigue, and may boost endurance, strength, and power performance. I get heightened focus during my training and increased energy. I sometimes take this with caffeine pills if I know that I'm going for an intense workout. I've always trusted GOLD brand for its quality ingredients.
First off, I really like California Gold Nutrition products. I think they offer good quality at good prices. The ingredients are good too, and provide lots of health benefits. This definitely helps with prolonged energy throughout the day, and for someone with chronic fatigue, that’s a huge help to me! And unlike a lot of caffeinated beverages, this formula doesn’t cause me any gastric discomfort or jittery feelings.
High-quality respected brand. Decent price for doses included. Easy to swallow capsule without aftertaste. Essential amino acid with demonstrated benefits in regard to anxiety & stress relief, tolerance. Improved cognition and focus. Caffeine included to counter balance any potential relaxing or sedating effect so that can remained alert with improved focus for better learning and memory.
Unfortunately always out of stock what a great combination and such high quality of potency in a great sized capsule, the packaging from iHerb is always at its best. Benefits of smooth caffeine shot that highly increase performance in demand without the unpleasant caffeine crash. Composition is the key factor in this supplement.Love it recommend it and want it again.
"I’ve been using TheanineUP™, L-Theanine & Caffeine plus Cocoa & Matcha for over 5 years, and it’s been a game changer for me. It boosts my energy and focus without any of the jittery feelings you get from caffeine alone. My productivity has been unbeatable since I started taking it. It provides a smooth and sustained energy boost that keeps me going throughout the day. Highly recommend it to anyone looking for a clean, effective way to enhance focus and stay energized!"
