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.

It's good for your gums.

Verified Purchase

It's been a few years since I started taking this product. I used to order from other places, but I finally settled on iHerb. My gums sometimes feel a bit off, so I take it whenever that happens. I don't take it consistently, but I still take a bottle, take a break, and then start again. It's not easy to take it three times a day, and the pills are rather large. I take it once or twice a day, whenever I remember.

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.

to lower cholesterol levels

Verified Purchase

I took beta-sitosterol to lower my cholesterol. The capsules are large, at first it was a bit difficult to swallow, but over time I got used to it. I take them during meals, especially when there is a lot of fatty food in the diet. I plan to take tests after the course to evaluate the effect. So far I have not noticed any side effects, the intake is going well. If my review was useful, I will be glad to like it!

gum

Verified Purchase

I heard it was good for my gums, so I bought it and took it... but honestly, I'm not sure if it really works. Maybe it's because my gums are weak and receding now, but... I'm just taking it because they said it was good. It's a bit big because it's a rectangular pill, so it's not easy to swallow.

I bought this for my parents who had gum pain.

Verified Purchase

The pills are a bit big, but not so big that I can't swallow them. I think I'll have to keep taking them to see if they're effective. There aren't any particular side effects. I trust the quality of Source Naturals, so I take them. The ingredient content is incomparable to that of Igatan.
