Perri: about a month ago

Chewable. Pleasant tasting. Not really sold on it's efficacy as per all of it's claimed benefits but it does seem to modulate anxiety. It didn't seem to have any negative side-effects so I'd buy it again but, perhaps, only while on sale.

Ella: a few months ago

Nice flavour, seems to work well. A bit pricey.

Larissa: a few months ago

I LOVE THESE! They are so great. I usually just use them for panic attacks instead of prescriptions

Leslie: a few months ago

A side effect of Hashimoto's thyroiditis can be, for some, an impaired ability to handle stress. This product absolutely makes a difference for me in that regard. I'm so happy I found it. I seem to be sleeping better as well even if only taking 1 chewable early in the day.

Vivian: about a year ago

there was a period of time I stopped using this and I was noticeable more stressed and anxious. This product does a fantastic job at keeping the stresses of daily life at a manageable level without other side effects such as sleepiness. I bought another product with l-theanine to try but I didn't realize it was one that also makes one drowsy. So I can only use that one at night before bedtime.

Great product. Works well to calm anxiety.
Another amazing product from SISU!

Karen: more than a year ago

First time I used this I noticed a real calming effect. That was a couple years ago. I've used l-theanine periodically both in capsule and in lozenge form. I keep a bottle at work. I like the lozenges. Sub-lingual form gets into your system faster. Recommended to my cousin and she swears by it.

L-theanine is a very useful supplement for lessening stress and anxiety. It helps me enormously. This SISU formula is easy to take, seems to absorb rapidly and doesn't taste half bad either. Also, as a rural Canadian I truly appreciate having access to such a wide selection of supplements, body care and home care products...thanks!

Manuela: more than a year ago

Moira: more than a year ago
