Zen Coffee, London Nootropics' adaptogenic coffee with L-theanine and Ashwagandha, is available at SuperKure, shipped from France within 24 to 48 hours, with no customs fees in Europe and free delivery on orders over €60. Ordering from a French site avoids import delays and lets you ask your questions to a French-speaking customer service team.
Each Zen sachet contains 153 mg of L-theanine and 110 mg of KSM-66® Ashwagandha root extract (5% withanolides), in an instant coffee made with 6% finely ground roasted coffee and a natural flavouring. According to the brand, the Ashwagandha extract is vegan. The box contains 12 sachets, with no preservatives or artificial sweeteners.
L-theanine is an amino acid naturally found in green tea. Its combination with caffeine is one of the most studied for attention: published work points to sustained attention with less jitteriness than caffeine alone. Ashwagandha is an adaptogenic plant from Ayurvedic medicine, associated with managing everyday stress.
Zen contains 80 to 110 mg of caffeine per sachet, a regular cup of coffee: it is not decaffeinated. The brand states it is popular with people sensitive to caffeine thanks to L-theanine and Ashwagandha, which promote calm, balanced energy. If you are very sensitive, start with half a sachet and avoid drinking it after 3 pm.
Add 1 sachet to a large mug with about 300 ml of hot water and stir to dissolve. Drink it black or with the milk of your choice. It tastes like a regular coffee, with a slight earthy note. The sachets are individually sealed, giving the brand a 12-month shelf life.
Zen is best drunk in late morning or early afternoon, for calm, steady energy during a busy day. The brand recommends 1 to 2 adaptogenic coffees a day. Zen is not a sleep product: it contains caffeine, so do not drink it in the evening.
Caffeine kicks in within about 30 to 60 minutes, with a feeling that L-theanine tends to make smoother. For Ashwagandha, allow several weeks of regular use before taking stock: most studies run 4 to 12 weeks.
Ashwagandha is authorised in food supplements in France, but ANSES issued precautionary recommendations in 2024. It is not recommended for pregnant or breastfeeding women, children and teenagers, or people with a thyroid or liver condition. If you are on medication, ask for medical advice before drinking Zen, which provides 110 mg of extract per sachet.
Yes, Zen is vegan. Like any caffeinated product, it is not recommended for children, pregnant or breastfeeding women, or in cases of high blood pressure or heart conditions. The brand does not guarantee the absence of traces of allergens (nuts, eggs, wheat): if you have an allergy, contact our customer service. Ask your doctor for advice before starting a new supplement routine.
Zen (L-theanine + Ashwagandha) suits you if you want calm energy, Flow (Lion's Mane + Rhodiola) if you want concentration and mental clarity, Mojo (Cordyceps + Siberian Ginseng) if you aim for physical energy and endurance. All three contain 80 to 110 mg of caffeine. The Selection Box lets you try all 3 blends in 12 sachets.
