Frequently asked questions

How does JitterShield work with coffee?

Simply drop a tablet into your hot or iced coffee, stir, and enjoy. The active ingredient (L-Theanine) works with caffeine to provide smooth, balanced energy.

Will it change the taste of my coffee?

No. JitterShield has a neutral flavour designed to complement your coffee without altering its taste. However, we're working on flavoured JitterShield tablets for those that love to spice things up!

What's in JitterShield?

JitterShield contains just five ingredients. No weird preservatives, flavour enchancers or processed junk.

Each dissolvable tablet contains:

80mg L-Theanine: A natural amino acid found in tea leaves that promotes calm focus. It balances the stimulating effects of caffeine, helping reduce jitters and anxiety while keeping your mind alert and clear.

Mannitol: A naturally derived sugar alcohol that gives the tablet a smooth, non-sticky texture.

Crospovidone: A super-efficient disintegrant that ensures the tablet dissolves quickly in your coffee.

MCC (Microcrystalline Cellulose): A plant-based binder that holds the tablet together.

Magnesium Stearate: A flow agent that prevents the ingredients from sticking during production, ensuring consistent quality.

How many tablets should I use per cup?

One tablet per cup is recommended for optimal results.

Does it get me "high", or contain mind-altering ingredients?

Nope. JitterShield isn't a mushroom or THC product, and it doesn't have any weird ingredients. The main active ingredient is L-Theanine, which is a well studied supplement which has been proven to lower stress and decrease the side effects of caffeine. L-Theanine is highly heat soluble, so none of the benefits are lost by high temperature water.
