We conducted a randomized, double-blinded, placebo-controlled trial to explore how consuming catechins from green tea affects symptoms like headaches during upper respiratory tract infections (URTIs). Our participants were healthy individuals who either received a bottled beverage containing 490 mg of catechins or a placebo without any catechins.
Impressively, we observed that those in the catechin group reported significantly reduced headache durations compared to the placebo group. Specifically, our findings showed a substantial improvement, highlighting the positive influence of catechins on not only headaches but also other URTI symptoms such as nasal congestion and running nose.
By integrating daily catechin consumption from bottled drinks, we discovered that these compounds can indeed help alleviate some discomforts associated with URTIs. Overall, this suggests that a simple addition to our diets, like enjoying green tea, could be beneficial in reducing the severity of headaches when dealing with winter colds.

Tea triggers headache
6 people found this helpful
Taking with Green Tea causes headache. I often drink green tea, and when I take this brand with it, I always get a severe headache that lasts a very long time. If you don’t drink green tea, I believe it should be fine, as I had no issues when I didn’t combine them.

Headache issue

Like someone else stated, this also gave me a headache. It advises against taking on an empty stomach, presumably due to the green tea content. I primarily use this for relaxation at night, as I prefer not to eat before bed. NOW is a great company, but I believe they fell short with this product.

Theanine has been a lifesaver during a challenging time in my life. My pressure was erratic, leading to various health issues, but after a month of consistent intake, I feel much better. There are moments when the stress resurfaces, but they are less frequent and easier to manage. My sleep has improved, and my mind is clearer—minor forgetfulness is less bothersome. The pressure stabilised, which has lessened my headaches. I feel calmer and can handle everything with more ease. I might consider increasing to 200 mg of theanine in the future for even greater tranquility, as it holds a top spot in my first aid kit.

Improves sleep

The medication promotes dopamine and serotonin production, enhancing thought processes, reducing anxiety, and stabilising the nervous system. Recommended by Dr. Bloom, I find it effective as a sedative. Taken at night, it significantly improves my sleep. Remarkably, my headache has disappeared. It's worth trying.
