This is magic on earth.
Size: 30 Count (Pack of 1)
These pills are actual magic. It’s not a placebo. I genuinely feel so much more calm and relaxed when I take one of these. It takes about 30 minutes to kick in, and I immediately feel my anxiety ease away. I usually take them on a stressful day or when I feel uneasy. They don’t upset your stomach, but you will be burping the smell of lavender.

Best alternative to other anxiolytics and anti-depressants
Size: 90 Count (Pack of 1)
As a healthcare professional, extensively studied this supplement. It's one of the best available in market to treat Generalized anxiety disorder along with other subthreshold anxieties. It really worked for me. Far better alternative to SSRI and benzodiazepines.

For Anxiety and Sleep
Size: 30 Count (Pack of 1)
Definitely recommend, a family members psychiatrist prescribed it vs big pharma medication as it's been proven to work as well as many anxiety meds without the side effects, it helped with the anxiety that my family member was diagnosed with, take before bed to calm the mind and for better sleep, and take it consistently

they're decent supplements
Size: 30 Count (Pack of 1)
my psychiatrist recommended these to me to help with my stress & anxiety induced insomnia but so far they don't really help a whole lot aside from making me a bit sleepy. it wore off pretty quickly the first few nights but overall i'd say they're pretty decent, just a bit on the spendy side to be getting regularly. they do cause some burping, though i expected that much going off of the reviews and it was only the first night i tried them.
