Good product
Verified Purchase
I've been using this for years to help lower my total cholesterol. My numbers have gone down below 200. Some of that is due to diet and some exercise. I plan to continue taking it. The tablets are a bit large but I don't think there's any way around that. The dosage is very good - hey it's MEGA. I hear it's good for the prostate too but I can't see any difference there.

For healthy and vital gums
Verified Purchase
I bought this to help manage stress and maintain healthy gums. I've been taking it regularly, and my gums feel healthier than before. It's a bit heavy, but it's easy to swallow. I think it's important to take it consistently.

Daily work essentials
Verified Purchase
As a surgeon, maintaining higher-order cognitive function and emotional homeostasis is a core requirement in the dual pressures of high-difficulty, long-duration surgeries and the professional environment of passing the external specialist examination (surgical specialist qualification examination). Traditional reliance on caffeine for alertness can easily lead to over-regulation of the sympathetic nervous system (such as palpitations, anxiety, or subsequent compensatory fatigue). To achieve a state of "awake yet relaxed" focus under high clinical pressure, I chose TheanineUP™, which features a patented synergistic ratio. The most outstanding aspect of this product is its "neurochemical antagonistic and synergistic mechanism." L-theanine can smoothly cross the blood-brain barrier (BBB), promoting the production of alpha waves in the brain and downregulating glutamate excitatory toxicity, while perfectly antagonizing the vasoconstriction and peripheral nerve excitation caused by caffeine. The combination of these two factors significantly extends time-on-task focus. In practical use, it demonstrates excellent "neuroprotective support," significantly improving the foggy feeling in the brain after continuous ward rounds without causing drastic fluctuations in morning heart rate. For colleagues who also need to make precise decisions in extreme clinical environments and pursue ultimate brain performance, this is a highly scientifically proven daily preparation tool.

It truly works to "normalize" men's comfort. After the course, you feel less discomfort and irritation, especially in the evening, when it's important to relax and unwind.

For gum health...
Verified Purchase
I bought it because I was worried about my gum health. I took it for a month and it was good, so I will continue to buy it. It seems to be more effective than I thought. The packaging and delivery were good, and the expiration date was good. I am satisfied.
