Each ingredient in Stress Fighter has been extensively tested and clinically proven to support its effect on stress, sleep and energy. We only used the most potent herbs and amino acids that have been carefully sourced worldwide. NO FILLERS, NO ARTIFICIAL INGREDIENTS, Just good science. 


Ashwagandha has been coined the wellness world’s favorite adaptogen, and with good reason. This herb is native to India and Africa and has been used for over 2,500 years as a revitalizer. Ashwagandha can help regulate cortisol, which can make you feel more calm and potentially soothe adrenal fatigue.

Rhodiola Rosea

Rhodiola Rosea is a stress-fighting, sleep-boosting adaptogen traditionally used in Eastern European and Asian medicine. Rhodiola supports the body’s ability to combat stress and anxiety, promote cognitive function, increase athletic performance, and ease fatigue.


L-Theanine is a water soluble amino acid that’s found in tea leaves that has a calming-yet-focused effect. Consumption of l-theanine is known to promote relaxation without drowsiness, support healthy blood pressure and fight the negative effects of stress-induced adrenaline secretion.

Apocynum Venetum

Apocynum Venetum has long been used in traditional Chinese medicine to reduce anxiety, promote restful sleep, and treat hypertension. Studies have also shown that Apocynum Venetum can alleviate symptoms of depression and elevate mood.

So far loving it!

I've only been taking REBL Jane for a couple weeks, but I'm loving it so far! No side effects and I have been feeling more energized!


I bought two bottles of stress fighter and I've been really impressed so far. I gave the other bottle to my sister and she had the same positive effects. We both have slept better, have had more energy and just a general increase in wellbeing. Highly recommend!


I was looking for a cortisol reducing product and came across this brand. I've been taking it for about 3 weeks and I'm really surprised how well it works. I just feel calmer and I've lost about 5 lbs. I'm not sure if its from the supplement or the fact that I feel so much better that I've been to the gym more. Either way, I'm happy;)

Cool company

I initially bought this product because I thought the story behind the brand was cool. Once I started taking stress fighter, I immediately noticed a difference in sleep. After a few more days I felt more relaxed during the day and I wasn't getting as tired at night. My BF suffers from anxiety so I bought a second bottle for him. He takes one per day and it seems to mellow him out at work.

Saved my husbands life;)

Great product that really took the edge off. It took about 2 weeks of consistency to really feel the difference. Once it kicked in, I was sleeping better and just feeling more energy throughout the day.
