Caffeine(Natural from Green Tea 98%)
Caffeine (Natural from Green Tea 98%) is a natural source of caffeine derived from green tea. Green tea contains a relatively small amount of caffeine compared to black tea and coffee. Caffeine is a stimulant that can boost mood, energy levels, reaction time, and memory. Along with caffeine, green tea also contains L-theanine, an amino acid that positively affects mood, lowers stress, and boosts dopamine and serotonin production.
Caffeine and L-theanine work together to improve mood. Green tea has been shown to have positive effects on weight loss, liver disorders, type 2 diabetes, Alzheimer’s disease, and more. Some studies have suggested that green tea might help prevent dental cavities, stress, and chronic fatigue, treat skin conditions, and improve arthritis by reducing inflammation.
There are several case studies regarding the benefits of green tea. One study found that green tea may protect against cardiovascular diseases and lower the risk of heart attack and stroke. Another study found that green tea may lower the risk of developing type 2 diabetes and heart disease. Drinking green tea may even help you lose weight as the caffeine and catechins it contains have been shown to boost metabolism and increase fat burning.
As for the recommended dosage, one study found that the caffeine content of 1 gram of green tea ranged from 11–20 mg. Another source suggests that EGCG 200 mg twice daily with food for 1 year is safe.
Excessive consumption of green tea can disrupt sleep and cause headaches because of its caffeine content. People with severe caffeine sensitivities could experience insomnia, anxiety, irritability, nausea, or an upset stomach after drinking green tea. Consuming a high concentration of green tea extract may negatively impact liver health in rare cases. Too much caffeine can lead to heart palpitations, high blood pressure, anxiety and other issues.
