Incredible value for money

L Theanine

100% L-theanine powder, providing 200mg of this non-essential amino acid in a 200mg serving.

L-Theanine is a non-essential amino acid that’s naturally found in green tea. It’s gained increasing popularity in recent years as an alternative to the Kava Kava herb. This L-theanine powder provides an easy way to increase your L-theanine intake, perfect for mixing into your favourite formula.

L-Theanine is a non-essential amino acid, which means it can be produced in the body with help from essential amino acids. However, we generally only consume small amounts of L-theanine in our diet, so some people prefer to up their intake with supplements.

The Purpose

Our L-Theanine powder is an ideal supplement for anyone who wants to increase their dietary intake of L-theanine. And because it’s unflavoured, it’s easy to mix into your favourite shake or smoothie blend.


  • Made for Mixing
    Ideal for mixing with your favourite shakes.
  • Incredible Price

Mix 1 scoop (approximately 200mg) with 50ml water in a Bulk™ Shaker Bottle, 1-2 times daily.

L-Theanine is best taken on an empty stomach. It also makes an excellent addition to a pre-bedtime shake.
