| **Also Known As** | 5-hydroxytryptophan, 5-HTP, L-5-hydroxytryptophan, oxitriptan, Griffonia extract, 5-hydroxy-L-tryptophan, serotonin precursor | Adenosine 5'-diphosphate precursor, ADO, Adenine riboside, 9-β-D-ribofuranosyladenine, Adenosine nucleoside, ATP metabolite, Cellular energy nucleoside |
| **Overview** | 5-Hydroxytryptophan (5-HTP) is an amino acid derivative that directly converts to serotonin in the brain, bypassing the rate-limiting enzyme tryptophan hydroxylase. This mechanism makes 5-HTP more effective than L-tryptophan for increasing central nervous system serotonin levels. | Adenosine is a naturally occurring nucleoside that binds to adenosine receptors (A1, A2A, A2B, A3) throughout the body. It primarily regulates cardiovascular function, sleep-wake cycles, and cellular energy metabolism through cyclic adenosine monophosphate (cAMP) pathways. |
| **Mechanism of Action** | 5-HTP crosses the blood-brain barrier and converts directly to serotonin via aromatic L-amino acid decarboxylase, bypassing the rate-limiting tryptophan hydroxylase enzyme. Increased serotonin activates 5-HT1A, 5-HT2A, and 5-HT7 receptors involved in mood regulation. Additionally, serotonin converts | Adenosine activates four G-protein coupled adenosine receptors (A1, A2A, A2B, A3), with A1 and A2A being most clinically relevant. A1 receptor activation decreases heart rate and atrioventricular conduction, while A2A activation promotes vasodilation and sleep regulation. These actions occur through |
| **Dosage** | Commonly taken in doses of 50-300 mg per day, divided into multiple doses. Consult a healthcare provider before use. | Typical dosage ranges from 10-30 mg per day in supplement form. Consult a healthcare provider before use. |
| **Safety** | Common side effects include nausea, diarrhea, and drowsiness, occurring in 10-15% of users at doses above 200mg daily. 5-HTP significantly interacts with SSRIs, MAOIs, and tramadol, potentially causing serotonin syndrome. Contraindicated in individuals with carcinoid syndrome due to risk of serotoni | Adenosine supplementation may cause flushing, chest discomfort, and transient heart rhythm changes due to its cardiovascular effects. It can interact with methylxanthines like caffeine and theophylline, which block adenosine receptors and reduce its effectiveness. Individuals with asthma should avoi |

## Adenosine — Full Health Benefits

- Supports cardiovascular health by regulating heart rate and blood flow, reducing the risk of arrhythmias and hypertension. This promotes a healthy heart function. - Enhances sleep quality by modulating neurotransmitters like adenosine, leading to deeper and more restorative sleep. - Supports cellular energy production by facilitating ATP synthesis, which is essential for all cellular processes. - Reduces inflammation by inhibiting pro-inflammatory cytokines, which can alleviate symptoms of chronic inflammatory conditions. - Enhances cognitive function by improving cerebral blood flow, potentially reducing the risk of cognitive decline. - Supports respiratory health by relaxing bronchial muscles, which can improve breathing in conditions like asthma. - Promotes skin health by increasing blood circulation, leading to a more radiant and youthful complexion.
