ANSIWELL FAST is a food supplement manufactured by Y Farma, a Portuguese specialist producer. ANSIWELL FAST has two main applications: 

  1. It stimulates concentration and mental focus, helping you to work or study through long hours with high output; 

  2. It reduces stress, anxiety, irritability and nervousness, enabling you to succeed in tasks such as presentations, meetings, and general activity. 


  1. L-Theanine is a patented molecule. This is an amino acid which occurs naturally in tea. L-Theanine counteracts the stimulating effects of the nervous system and has the ability to induce a feeling of natural relaxation and mental alertness, without causing drowsiness.

  2. Magnesium is a mineral critical for learning processes, formation of neuronal connections and in memory.

  3. Vitamin C acts as an antioxidant, protecting cells from damage. The body also requires Vitamin C to make collagen; to absorb iron from plant-based foods and to support the immune system. 



L-Theanine stimulates the production of alpha brain waves, which provides a peaceful state of mental alertness and an improvement in intellectual productivity. This means you can concentrate on your task for longer and be more productive, always in a relaxed way.

L-Theanine also decreases the production of beta brain waves. These are the predominant waves in individuals with stress, excitement and anxiety. L-Teanine promotes general brain relaxation, without causing drowsiness.

L-Theanine has an anti-stress effect and induces relaxation and mood stabilization, as it is involved in the process of regulating neurotransmitters (serotonin and dopamine), which are responsible for the states of excitement and relaxation in the brain. 


For Concentration and Focus  

Take 1 capsule in the morning, after breakfast, every day. If necessary, take one more capsule during the day.


For Restful Sleep

Take 1 capsule 1 hour before bedtime. ANSIWELL FAST promotes quality sleep with restful sleep. For an effective emotional stabilisation, a minimum treatment of 4 months is recommended, with no defined period regarding the maximum duration of the dose.


For Stress and Anxiety

Take 1 capsule in the morning + 1 capsule, 30 minutes before the anxiety-generating situation or as necessary. You should start taking ANSIWELL FAST preferably 5 days before the anxiety-generating situation).


The effects of ANSIWELL FAST start after 30 minutes, being perfect for situations of greater stress or anxiety, such as an exam day, or when you have to speak in public. Taking ANSIWELL FAST helps to control anxiety and feel more confident (less tachycardia, less sweaty hands).
