Each Revive Daily serving (2 capsules) encompasses:

• Arginine (1200mg) - L-arginine is an amino acid that acts as a building block of proteins, stimulates insulin and releases nitric oxide into the blood. In other words, the latter helps widen blood vessels essential for healthy circulation. A 2008 review set out to understand the effect of exercise and L-arginine supplementation on GH responses and summarized some interesting points.
• First, the authors found that GH responses increase over a dosage range of 5 to 9 g and, adding that the results are dose-dependent and any higher values ​​will not be well tolerated. Second, the combination of exercise and GH is more beneficial, as it has been shown to increase those levels by at least 300-500% compared to 100% at rest. A more recent randomized controlled trial found that acute arginine supplementation moderately increases GH at 1.5 hours, while also stimulating the production of thyroid hormones.
  
• Lysine (1200mg) - The second amino acid qualified for the Revive Daily formula is L-lysine. Unlike the former, which is naturally available through body productions, L-lysine is an essential amino acid, which means that the body does not produce it. A preliminary study from 1981 that examined the combined effects of 1200 mg of L-lysine and 1200 mg of L-arginine on GH secretion found significant results. They said that "the effect appeared to be specific to the combination none of the amino acids demonstrated appreciable stimulant activity."
• A recent study on the effect of L-lysine on 12 growing pigs during an 8-week study reported that the absence of lysine could be the reason for a reduced body protein synthesis, with an impact not only on the ratio gain-feeding and measures of average daily gain, but also cell signaling and metabolic pathways dissociated from GH.
  
• L-Theanine (200mg) - The next amino acid in the Revive Daily formula is L-Theanine, which is found mainly in green and black tea. In terms of benefits, existing studies have linked it to anxiety and stress relief, with symptoms relieved. When combined with caffeine, it could go so far as to boost focus and boost immunity. Interestingly, the same dosage found in this formula has been shown to reduce resting heart rate, which in turn could promote relaxation and help people fall asleep. This is because the amino acid interacts with brain chemicals that play a vital role in inducing sleep
• Ashwagandha Extract (150mg) - Ashwagandha is an Ayurvedic herb containing chemicals believed to be essential for calming the brain, reducing swelling, lowering blood pressure levels and increasing immunity. In general, this herb is perceived as an adaptogen, which means it is meant to help the body resist physical and mental stress. A study that looked at the efficacy and safety of weed in patients with insomnia and anxiety reported improvements in sleep onset latency, sleep efficiency, and scores on both the Pittsburgh Sleep Quality Index (PSQI) and Hamilton Anxiety Rating Scale (HAM-A)
• 5-Hydroxytryptophan (100mg) - 5-hydroxytryptophan (5-HTP) is a chemical in the body made from an essential amino acid called tryptophan. When the aforementioned conversion occurs, the chemical then transforms into serotonin, which is a type of neurotransmitter that transmits signals between brain cells. To put things in better context, increasing serotonin levels in the brain can help regulate mood, behavior, and possibly sleep, mood, anxiety, appetite and pain sensation. Another justifiable source in favor of 5-HTP, as it may work by increasing melatonin
• Melatonin (10mg) - The discussion of 5-HTP brings us to the next ingredient, which is an exogenous version of our sleep hormone called melatonin. Some research suggests that melatonin supplementation could help treat sleep disorders, particularly delayed sleep phase and relief from insomnia and jet lag. In addition to the reported benefits, melatonin is sought after because it will not cause addiction or induce a hangover effect. Common side effects include headache, dizziness, nausea, and sleepiness.
• Magnesium (50mg) - Magnesium is a mineral whose role is multi-fold. It has been linked with healthy muscle and nerve function, blood pressure levels and immunity. On average, the adult body contains 25g of magnesium, where an equal amount is stored in the skeletal system and muscles, soft tissues, and bodily fluids respectively. A deficiency is quite common, potentially putting people at risk of experiencing poor bone health, diabetes, anxiousness and migraines among others.
• Zinc (15mg) - Zinc is an essential trace mineral believed necessary for the chemical reactions of 100 enzymes. Predominantly, DNA production, cell growth, muscle building, healing of damaged tissue, and ensuring healthy immunity may not be completely possible with zinc as the missing piece of the puzzle. A study examining the effect of zinc supplementation on the growth hormone-insulin growth factor of 50 prepubertal Egyptian children (with a deficiency) found that the aforementioned parameter requires long-term zinc intake for rectification.
