Key Benefits

  • Helps relieve stress and anxiety.

  • Promotes relaxation.

  • Supports restorative and better sleep quality.

Calm My Brain is a sceintifically formulated supplement designed to support relaxation and a balanced response to stress. Whether you're feeling overwhelmed, struggling with anxious thoughts, or finding it hard to unwind, this advanced formula works to calm the mind and body naturally.

This formula combines four highly absorbable forms of magnesium— threonate, bisglycinate, malate, and citrate—to ensure the body gets the most out of every dose. Each type plays a role in supporting brain function, nerve signalling, and muscle relaxation. Often called the "relaxation mineral," magnesium helps regulate neurotransmitters and stress hormones, promoting a sense of calm and balance. 

L-Theanine, an amino acid found in green tea, enhances alpha brain wave activity, encouraging relaxation without drowsiness. It helps ease tension while maintaining focus, making it ideal for daytime use. KSM-66® Ashwagandha is a clinically studied adaptogen that helps the body manage stress. Traditionally used in Ayurvedic medicine, ashwagandha supports cognitive function, reduces anxiousness, and promotes restorative sleep.

Together, these ingredients work synergistically to restore balance, ease mental tension, and support emotional wellbeing.

Calm My Brain delivers fast-acting relief, thanks to its potent 400 mg dose of L-theanine, which enhances alpha brain wave activity for a sense of calm without drowsiness. Clinical studies show that L-theanine takes effect within 30 minutes, helping to quiet overactive beta waves linked to stress and tension. This rapid action allows Calm My Brain to deliver noticeable results within 40–60 minutes, helping you feel more relaxed and focused when you need it most.

BrainMD optimises brain health with science-backed supplements. Founded by Dr Daniel Amen, the brand formulates solutions with clinically researched ingredients in scientifically determined dosages to help the brain function at its best. Their range includes high-quality nootropics, multivitamins, omega-3 supplements, and more—each designed to nourish the brain, the control centre of the body, for better overall health and wellbeing.
