FAQs About Integrative Therapeutics L-Theanine Capsules

Q: Does this make you sleepy during the day? A: Usually not. L-theanine is more for relaxation without that groggy feeling, so a lot of people take it during the day without a problem.

Q: How many capsules should I take? A: I'd start with 1 capsule and see how you feel. The suggested use is 1 capsule up to 3 times a day, and some people take 2 capsules 3 times a day if they want stronger support.

Q: What's actually in this one? A: The active ingredient is L-theanine. This one uses Suntheanine®, which is a branded form a lot of people specifically look for. The other ingredients are pretty simple: cellulose, a vegetable capsule, and magnesium stearate.

Q: Should I take it with food or on an empty stomach? A: Either is usually fine. Most people do well taking L-theanine with or without food, so I'd just go with whatever feels easier on your stomach.

Q: I've heard L-theanine helps with sleep. Can I use this at night? A: Yes, a lot of people do. It isn't the kind of thing that knocks you out, but taking a capsule in the evening may help you unwind if your mind keeps going at bedtime.

Q: My doctor said to be careful with supplements. Are there any medication concerns with this one? A: Yes, I'd still check first if you're on medications or have a health condition. The brand recommends talking with your doctor if you're pregnant, nursing, or taking any medications.
