Geniposide is said to be an iridoid glycoside, extracted from the fruits of Gardenia jasminoides. Gardenia jasminoides is said to have been used as a dietary supplement in China for hundreds of years, for a variety of purposes, including mood support (Ye et al., 2018).*
Recent preliminary studies have indicated that geniposide may indeed play a role in helping to support a positive mood, although knowledge regarding the mechanism is limited and further research is needed (Cai et al., 2015, Zhao et al., 2018, Zhang et al., 2019, Sun et al., 2020, Yuan et al., 2020).* This is a research area of keen interest to certain companies and Zenstra does not wish to comment further on geniposide at this time. Further research may possibly be found online by searching for the term "geniposide mood," or by reading any of the aforementioned studies.

5-HTP (5-hydroxytryptophan) is said to be a compound that our body allegedly synthesizes from the amino acid tryptophan, which is said to be found in seeds, eggs, salmon and turkey. Our bodies are said to use 5-HTP to make serotonin.* Serotonin is thought to play a role in mood, appetite and autonomic functions.* 5-HTP may help to support a positive mood.* Studies have suggested it may also potentially play a role in maintaining reduced sugar cravings.* The 5-HTP we use is extracted from the seeds of the African shrub 'Griffonia simplicifolia.'
Polygala tenuifolia also known as Yuan Zhi, is a root which has been traditionally consumed in Asia to support memory, calmness and sleep.*
Bacopa monnieri is said to be an adaptogenic herb which has been traditionally used as a supplement to help maintain memory and support a calm mood.* Some research has suggested it may function by supporting the modulation of the dopaminergic and serotonergic systems.* Another study suggested it may help to support the regulation of cortisol.* Cortisol is thought to be a hormone linked to stress.* Other studies have reported that it may be beneficial for helping to maintain memory and support cognitive performance.*
Gotu kola (Centella asiatica), which has been referred to as the “herb of longevity,” is said to have been traditionally used in Asia to support calmness, a positive mood, brain health, skin health, as well as liver and kidney health.*
Phosphatidylserine is said to be a compound similar to a dietary fat which is thought to be prevalent in human brain tissue.* It is said to be vital for cognitive function and is thought to be synthesized naturally in our brains.*
Schisandra chinensis (five flavour fruit) is a vine which seemingly typically bears purple-red berries described by some as apparently amalgamating all five tastes: sweet, sour, salty, bitter and spicy. Schisandra berry is said to be categorized as an adaptogen, as it is thought to help the body maintain a healthy response to stress.* It may potentially help to support healthy energy levels by helping to support neural ATP synthesis, as well as brain function, relaxation and healthy blood circulation.* Additionally, it has been suggested that Schisandra may potentially help to support the liver.*
Very good formula, worth buying.
This has definitely improved my wife's outlook and mindset. She no longer gets upset over things beyond her control, and rarely reacts to other people's poor behaviour and manners! Will be placing another order very shortly. Thanks!
Very good, negative thoughts are decreasing and I just feel better overall
I have been taking Zen 1 for 6 months now and they work for me. With someone that deals with depression, they give me the energy boost that I need. I have also started taking Lemon Aid as I have been struggling to sleep and also find these help me relax. Great products and highly recommended.
Having been on way too many prescribed medications, some beneficial, others with umpteen side effects, it's a wonderful feeling to take a supplement that does what its claimed to do, I need mental clarity after all the brain fog of previous said meds and this does it !
Highly recommended this company to most people I know, great customer service, very knowledgeable and prompt delivery.
Best customerservice on the Internett ❤️Also Great product 👌👍
My wife takes these as a replacement for prescription antidepressants. She'd been on those for a long time and had to wean herself off those gradually whilst taking the Zen1 as well.
Now though, 4 months in, she has been completely free of the antidepressants, taking 1x Zen1 per day normally, or if she's having a particularly difficult or stressful day, she occasionally takes another one that day.
For her, it's been fabulous and I'm delighted for her and with her happiness levels.
as ever - all products are 5*
