Quick answer
200mg capsules give you more flexibility (you can follow the label in smaller steps), 400mg capsules give a higher amount in a single capsule, and 400mg gummies are flavoured and need no water. Compare the amount per serve and price per serve to choose.

When the 200mg capsule makes sense
A lower-strength capsule lets you follow the label directions in smaller steps. A 120-capsule pack also lasts a long time.
When the 400mg capsule makes sense
If you want a higher amount without taking multiple capsules, a 400mg capsule keeps things simple: one capsule, no taste.
When gummies make sense
Gummies are a good fit if you struggle to swallow capsules or simply prefer a chewable. They are flavoured and often contain sugar or sweeteners, so check the label if that matters to you.
How to compare value
- Find the price of each pack.
- Divide by the number of serves.
- Compare the milligrams of L-theanine per serve.
Tip: Capsules usually cost less per milligram than gummies.
