There are a lot of different reasons you may choose to take L-Theanine each day, and your specific needs will affect when you should take your L-Theanine dose. Some factors that may impact your decision include:
Although there is some leniency in when you should take L-Theanine, here are some of the most common reasons and times it is used:
If you're using l-theanine to boost your focus or energy levels, we recommend taking it first thing in the morning, ideally about 30 minutes before breakfast.
If you intend to use L-Theanine to help you sleep at night, take your dose about 30-60 minutes before bed.
Some sources suggest that L-Theanine may have benefits for anxiety. If you intend to take L-Theanine for anxiety, you may try taking L-theanine in multiple doses spaced evenly throughout the day. Some people take a small to moderate dose of L-theanine every 3-4 hours for these purposes.
L-Theanine may take about half an hour to be absorbed, and it may take up to an hour to feel the full effects of your L-Theanine dose. Moreover, L-Theanine relies on a systemic response that helps create balance within the body, so you may need to take it daily for 2 to 3 weeks to experience optimal benefits.
On average, people take between 100-500 mg of L-theanine daily, and the total dosage may be divided into three smaller doses taken throughout the day.
We recommend you start with small doses and increase slowly as needed, allowing several days to evaluate the effects before changing your dosing routine. An L-theanine powder makes it easy to adjust your dosage. Talk to your doctor for help adjusting your wellness routine. Taking the correct dosage is the best way to avoid L-theanine side effects.
