I experience severe discomfort without any specific diagnosed diseases or injuries. When I take 6g of arginine jelly and a 200mg caffeine caplet, I feel completely fine after about 30 minutes. Does this make sense, or could it just be a placebo effect?
ChatGPT’s answer is:
This reaction can indeed make sense, as both L-arginine and caffeine can have physiological effects that might temporarily alleviate feelings of discomfort or low energy.
L-arginine Effects: Arginine is an amino acid that helps increase nitric oxide production, which can improve blood flow and enhance oxygen delivery to tissues. This process can lead to feelings of improved energy or reduced fatigue, which may contribute to your overall sense of relief.
Caffeine Effects: Caffeine is a central nervous system stimulant that can improve alertness, reduce perceived fatigue, and elevate mood temporarily. The 200mg dose is considered moderate and can boost energy levels, often providing relief if discomfort is related to low energy or mental fog.
Placebo Factor: While these effects are likely real and based on the substances’ mechanisms, the placebo effect could still play a role, especially if your body has come to expect relief from this combination. The mere anticipation of feeling better can amplify the effects, making the combination feel even more effective.
In summary, it’s plausible that both physiological effects and placebo may be contributing to the relief you experience.
metabolized to produce catecholamines such as dopamine (DA) and norepinephrine (NE) taken as a supplement to help increase catecholamine levels depleted during stressful or challenging conditions
used in the production of thyroid hormones
benefits
related to its ability to replenish catecholamine levels in the brain, which can become depleted under stressful conditions
Multiple studies have demonstrated that L-tyrosine can help to prevent declined cognitive function under stressful, cognitively demanding conditions
Although it has not been shown to improve memory under resting conditions, L-tyrosine supplementation has been shown to alleviate reduced memory under acutely stressful conditions.
Overall L-tyrosine appears to be safe and well-tolerated at moderate doses, with one 2-week human trial using a dose of 2500 mg, provided three times per day, and another trial using single doses of up to 150 mg/kg of body weight (around 10,000 mg for a 68 kg/150 lb individual), both with no adverse effects.
drawbacks
Although L-tyrosine has shown beneficial effects in some studies, it has a mixed track record for efficacy, with some studies failing to observe positive effects on cognition.
This may be partially explained by the fact that L-tyrosine increases catecholamine synthesis only when catecholamine levels are depleted, limiting efficacy to sufficiently stressful or challenging conditions. Efficacy may also vary in different individuals, as highlighted by one study that found that the effects of L-tyrosine on cognitive function become detrimental with older age.
There are also possible contraindications for L-tyrosine supplementation in people with hyperthyroidism or anyone taking L-dopa or monoamine oxidase inhibitors. If this applies to you, consult with your physician before supplementing with L-tyrosine.
works
used in the body to make the catecholamines dopamine (DA) and norepinephrine (NE), which can become depleted under stressful or cognitively challenging conditions.
After supplementation, L-tyrosine levels in the blood peak after one to two hours, and stay elevated for up to eight hours.
then passes through the blood-brain barrier, where it is absorbed by brain cells and converted in a series of enzymatic reactions to DA, which can be converted to NE through the action of another enzyme.
The ability of L-tyrosine to enhance catecholamine synthesis only in neurons that are actively firing may explain its ability to reverse the effects of neurotransmitter depletion during stress
dosage
tends to be taken in doses of 500–2000 mg approximately 30–60 minutes before any acute stressor (this tends to be exercise)
Studies in humans showing most anti-stress promise for acute supplemental L-Tyrosine use a dosage range of 100–150 mg/kg of bodyweight which can be taken 60 minutes before exercise; this is a dosage range of 9–13.5 g for a 200 lb person and 7–10 g for a 150 lb person.
If using higher doses and finding digestive issues, this may be split into two doses separated by half an hour (30 and 60 minutes prior to acute stress).

Possibly up to 1,500 American officials at home and abroad have suffered brain and other injuries in recent years from a mysterious malady that is reported to have begun in Havana in 2016 and has since been known as Havana Syndrome.
While aspects of these health incidents remain a mystery, they recall a series of historically documented Soviet technical operations against the US embassy in Moscow that began in 1953 and lasted for decades, providing credible evidence of serious harm to numerous diplomats and other US officials.
Since the fall of the Soviet Union, President Vladimir Putin and Russian military officers have publicly bragged about developing weapons that could cause health effects similar to Havana Syndrome. After attacks on officials of successive administrations, CIA Director William Burns may finally have put an end to such incidents by threatening the Russians with retaliation.
But the policy of tolerating, denying, and concealing decades of Russian attacks, at the expense of American officials, has harmed the credibility and weakened the power of the US government to deter other acts of aggression.

A yearlong investigation by The Insider, in collaboration with 60 Minutes and Der Spiegel, has uncovered evidence suggesting that unexplained anomalous health incidents, also known as Havana Syndrome, may have their origin in the use of directed energy weapons wielded by members of Russian GRU Unit 29155. Members of the Kremlin’s infamous military intelligence sabotage squad have been placed at the scene of suspected attacks on overseas U.S. government personnel and their family members, leading victims to question what Washington knows about the origins of Havana Syndrome, and what an appropriate Western response might entail.

CIA physician Dr. Paul Andrews was one of the first people sent to Havana, Cuba, to investigate a spate of mysterious health incidents that were impacting embassy and agency personnel in 2017 when he was struck by the same set of debilitating symptoms, he told CNN Chief Medical Correspondent Dr. Sanjay Gupta in his first public interview for a CNN Special Report: “Immaculate Concussion: The Truth About Havana Syndrome.”

A definitive diagnosis of CTE can only be made during an autopsy, as it cannot be confirmed in living individuals. While some researchers link certain signs and symptoms to CTE, no conclusive test exists to identify it in living people. Additionally, the signs often resemble those of other neurological conditions like Alzheimer’s.
이런 종류로 가장 평이 좋은 것이 Brydge 12.9 MAX+이다. 나는 iPad가 이 장치로부터 떨어져 있을 때에도 보호되는 것이 좋은데 11inch나 Air용과 달리 12.9inch용은 그렇지 않다. (이 문제로 iPad 주문 후 바로 이 제품도 주문했다가 곧 취소했더랬다. 최근에 이보다 내게 더 나은 넥스텍 프로를 발견하여 잘 취소했다는 생각.)
이 제품은 두 개의 hinge로 부착된 iPad의 각도, 높낮이 조절을 자유롭게 할 수 있고 아래와 같은 회전을 360°할 수 있다.
이 장점은 특수 key들과 함께 이 제품을 Apple이나 Brydge 제품보다 더 훌륭하게 한다. Apple 제품의 trackpad를 따라갈 수 있는 것은 없을 것이라고들 하나 그것과 비교하지 않으면 충분히 좋은 trackpad를 가지고 있고 가능한 touch gesture들이 모두 지원된다.
무겁지만 무게는 포기한 것이니 기억만 하고 지나간다. 970g. (Brydge 것도 같은 무게, Apple 것은 710g)
