Q1: What is L Theanine supplement used for?
L Theanine supplement supports relaxation without causing drowsiness, helps maintain mental focus and cognitive clarity, and supports a healthy stress response. It also helps maintain healthy sleep quality when taken before bed and supports alpha brain wave activity associated with relaxed alertness. L Theanine is one of the most researched natural amino acids for calm, focused mental performance, Health Canada licensed with NPN 80068090.
Q2: What is L Theanine and where does it come from?
L Theanine (gamma glutamylethylamide) is a non protein amino acid found almost exclusively in the leaves of Camellia sinensis, the plant used to produce green, black, white, and oolong tea. It is the compound primarily responsible for the calm, focused mental state associated with green tea consumption, distinct from the stimulating effects of caffeine. L Theanine crosses the blood brain barrier and exerts direct effects on neurotransmitter activity and brain wave patterns.
Q3: How does L Theanine support relaxation without causing drowsiness?
L Theanine promotes alpha brain wave activity (8 to 14 Hz), the brain wave frequency associated with relaxed alertness, creative thinking, and focused calm. Unlike sedatives, L Theanine does not suppress central nervous system activity. Instead, it modulates GABA, serotonin, and dopamine pathways to promote a balanced, calm mental state while maintaining full alertness and cognitive function. Research using EEG has consistently demonstrated increased alpha wave activity within 30 to 60 minutes of L Theanine ingestion.
Q4: Can L Theanine be taken with caffeine?
Yes. L Theanine is widely studied for its ability to complement caffeine by supporting mental focus and cognitive clarity while helping reduce the jitteriness and anxiety sometimes associated with caffeine consumption. Research suggests that L Theanine and caffeine together support attention, working memory, and reaction time more effectively than caffeine alone. This combination is one of the most well researched pairings in cognitive performance supplementation.
Q5: Is L Theanine good for sleep?
L Theanine helps maintain healthy sleep quality by promoting relaxation and supporting GABA activity, the primary inhibitory neurotransmitter involved in sleep onset and nervous system calming. Unlike sedative sleep aids, L Theanine does not cause grogginess or impair cognitive function the following day. For sleep quality support, take 30 to 60 minutes before bed as directed by a healthcare practitioner.
Q6: What are alpha brain waves and why do they matter?
Alpha brain waves (8 to 14 Hz) are the brain wave frequency associated with a state of relaxed alertness, creative thinking, and focused calm. They are typically observed during meditation and in states of wakeful relaxation. L Theanine is one of the few natural compounds shown in EEG research to reliably increase alpha wave activity, supporting a calm, focused mental state without sedation or stimulation.
Q7: Is this L Theanine supplement licensed by Health Canada?
Yes. This product is a licensed Natural Health Product with NPN 80068090, approved by Health Canada under the Natural Health Products Regulations. It is manufactured in a GMP certified facility in Canada.
Q8: Why is 250mg of L Theanine significant?
At 250mg per capsule, this formula provides a high potency, clinically relevant dose of L Theanine. Most clinical research on L Theanine and cognitive performance, relaxation, and stress support uses doses in the range of 100mg to 400mg. A 250mg dose provides meaningful support at the higher end of the commonly studied range, making it suitable for adults seeking more pronounced relaxation and focus benefits.
Q9: Is this L Theanine supplement vegan and gluten free?
Yes. This product uses a hypromellose vegetable capsule with no gelatin or animal derived ingredients. It is also gluten free and non GMO, with no artificial colours, flavours, sweeteners, or preservatives.
Q10: How long does one bottle of L Theanine 250mg last?
Each bottle contains 60 vegan capsules. At 1 capsule per day it provides a two month supply. At 2 capsules per day it provides a one month supply.
Q11: Can L Theanine be taken every day?
L Theanine is formulated for daily adult use. It is non habit forming and does not cause dependence or withdrawal. For guidance on long term use or use alongside medications, consult a healthcare practitioner.
Q12: Where is this L Theanine supplement manufactured?
This product is made in Canada in a GMP certified facility operating under Health Canada oversight. NPN 80068090.
