- Product Information
Introducing our new double-strength L-Theanine capsules. L-Theanine supports a sense of calm, contentment and well-being. It crosses the blood brain barrier and has been shown to increase brain alpha waves in less than 40 minutes. Alpha brain waves are an indication of a state of relaxation and mental alertness similar to that achieved through meditation, this promotes a feeling of relaxation but with an alert state of mind. This is particularly useful to know as it can be taken during the day to support relaxation without a sedating effect.
Theanine is an amino acid found predominantly in tea. When you have a stressful moment or a shock the immediate thought (well for us Brits anyway) is to have a 'cuppa'! A joke to some maybe, but is there a real reason as to why? Yes, it's L-Theanine, which is believed to be responsible for the calming and relaxing effect brought about by a good old cup of tea.
L-theanine facilitates the production of GABA (a neurotransmitter that has a calming effect on the brain), it has also been shown to support quality sleep and may have a positive effect on memory and learning.
