We offer excellent value across our supplement range. How do we do it? It’s simple: we offer larger bottle sizes.
While many competitors sell bottles containing 30 or 60 capsules, we offer options of 120, 240 and 360 capsules. Buying in larger quantities reduces the cost per capsule and per serving, helping you save up to approximately 50% compared with smaller competing packs.
That means we can offer more affordable prices without compromising on quality, purity or manufacturing standards.

L-Theanine has been great for me, more people should know about it. It's not the most expensive, so worthy trying if you think it could help, IMO
I love your L-Theanine but want to order more. When are you expecting stock? I give it 5 big stars
So many benefits of green tea, due to the l-theanine. Love how you can just take the l-theanine itself.
