Zen1 is our mood support formula, containing geniposide. Geniposide is a relatively recently discovered natural compound, extracted from the fruits of Gardenia jasminoides. Zen1 combines geniposide with 6 other ingredients which research suggests can help to support the functioning of central serotonergic pathways associated with mood.* A number of these ingredients can also be beneficial for maintaining composure and mental clarity, among other benefits.*
Further details on the Zen1 formula can be found on the scientific research page.
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.*
I haven't received it yet
Purchased item several weeks ago, item was returned to sender by DHL, DHL say contact seller. seller customer service email bounces back, very disappointing because order regularly on this site and the products are genuine really good
Hi Raymond, we are terribly sorry about the issue with DHL. The EU recently changed customs labelling requirements and our UK fulfillment centre was unaware of the new changes. We have updated our package labelling and your order has been reshipped. We are so sorry once again Raymond.
Taking Zen1, Lemello and Invictimmune daily for more than a year. All great products!
Dies ist bereits meine 3. Bestellung der ZEN-Tabletten. Absolut empfehlenswert!
These supplements have massively improved my wellbeing through times that I have felt stressful. They massively help with brain fog, allowing me to get through the day with much more energy and an overall more optimistic view on life. I can’t thank the team at Zenstra enough for these life changing supplements
I am so happy that a friend recommended Zen 1 to me, this has been a game changer, for my mental and emotional health and has reduced anxiety, enhanced mental focus and clarity and general feeling of wellbeing.
Bought zen 1 for myself and my daughter and we bought havd found it has really helped us deal with our stress . I find this a great company to deal with and all their products are excellent.
I take 1 a day. I didn't notice any immediate effect, but after a few days there was a gradual improvement in overall mood & reduction in stress levels. For me the gradual change was preferential to something that has an immediate effect, which can result in ups & downs, whereas with Zen 1 you're on an even keel.
