The Science behind FLOWSTATE

We believe in transparency. That’s why our FLOWSTATE™ blend is built on ingredients with credible research, not marketing buzzwords. Each glass delivers measurable amounts of active ingredients, and two glasses provide the functional range supported by scientific studies.

L-Theanine

  • What it is: An amino acid found naturally in green tea.

  • Why it matters: Research shows that 200–400 mg of L-theanine can promote relaxation without drowsiness, and help with focus and mental clarity.

  • In FLOWSTATE™: Two glasses provide 200 mg, right within the studied range.

Magnesium Glycinate

  • What it is: A gentle, bioavailable form of magnesium.

  • Why it matters: Magnesium supports the nervous system, helping regulate stress response and relaxation. Studies suggest it can reduce mild anxiety and improve resilience to stress.

  • In FLOWSTATE™: Two glasses provide 240 mg magnesium glycinate, a meaningful addition to your daily intake.

We've combined well-chosen ingredients, in real amounts, backed by science. FLOWSTATE™ is designed to work with you, so you can enjoy the ritual of wine in a way that supports both mind and body.

L-Theanine

100 mg per glass (200 mg in two glasses)

What it is:
An amino acid found naturally in green tea leaves.

What the science shows:

  • L-theanine crosses the blood–brain barrier and influences neurotransmitters including GABA, dopamine, and serotonin, which are linked to calm and focus.

  • Randomized controlled trials show that doses in the range of 200–400 mg can reduce stress responses and promote relaxation without drowsiness.

  • L-theanine has also been studied for its ability to improve attention and mental clarity in both relaxed and stressed states.

Magnesium Glycinate

120 mg per glass (240 mg in two glasses)

What it is:
A chelated form of magnesium bound to glycine, prized for its gentle effect on digestion and superior absorption compared to common forms like magnesium oxide.

What the science shows:

  • Magnesium is essential for the nervous system, acting as a natural NMDA receptor antagonist to prevent neuronal overstimulation. This is an important mechanism in stress regulation.

  • Supplementation has been shown in clinical studies to reduce perceived stress and support mood stability.

  • A Phase IV randomized controlled trial confirmed that magnesium supplementation significantly lowered stress scores in adults with both low magnesium and high stress.

  • Systematic reviews suggest magnesium may help alleviate anxiety and stress-related symptoms, particularly in people with higher baseline stress.
