THE amino acid L-theanine is my new obsession.

That may sound a bit strange but after trying everything for my , this actually works.

L-theanine is found in various types of tea – especially green tea – and certain mushrooms.

It can also help you deal with stress. If you’re anxious, go for between 200mg to 400mg a day.

PILLS

SO, these are the pills I took, and now take every night, which made me realise how much I love this stuff.

L-theanine is an amino acid that has a natural, calming compound to reduce stress, improve focus and aid sleep.

It counter-balances cortisol’s effects on the nervous system, too.

These Willpowders Calm capsules consist of 200mg L-theanine with a bit of a natural bulking agent, so they are pure, simple and effective.

I wouldn’t be without them now.

If you don’t like capsules, you can empty the powder into drinks or food.

TEA

L-THEANINE is mainly found in green and black tea and some mushrooms.

And one of the best ways to consume it, if you’re kicking off your day, is by having a cup of matcha tea – like green tea but with a slight aftertaste of green veg.

Dirtea’s Matcha Mushroom Super Blend combines L-theanine with matcha to produce a sustained calm focus lasting up to six hours.

Thanks to the coconut sugar, coconut milk and mango, it tastes fab. Add some milk for a luxe drink. On offer, £39 plus a free scoop for a 30-serving pouch.

CAPSULES

THESE Calm Capsules from Revive Active contain the same amount of L-theanine as the Willpowders capsules but also have other ingredients to help relax you.

There is 30mg of saffron from the crocus flower, praised for its mood-boosting properties, and 300mg of ashwagandha that is said to help the body cope with stress.

The capsules also contain calming lemon balm and magnesium bisglycinate.

Vitamin C, B6, B12 and D are in the mix for stress, mood and adrenal support, and I found them good for aiding sleep, too.
