Scientific Evidence

改善脱发研究

Improves concentration and improves ADHD*

Magnesium helps reduce the symptoms of attention deficit and hyperactivity disorder (ADHD) by regulating the balance of neurotransmitters and maintaining normal brain function. Magnesium's anti-anxiety effects also help improve concentration, allowing people to focus better at work and school. A trial focusing on patients with ADHD showed that 47% of the subjects met the response criteria and achieved improved concentration after magnesium supplementation.

提升睡眠质量研究

Promotes brain health*

Magnesium enhances synaptic plasticity—crucial for memory formation and storage. L-Threonate is especially effective, crossing the BBB to raise brain Mg and boost memory and learning.

延缓生理衰退研究

Improves sleep quality*

In seniors with primary insomnia, dietary Mg significantly increased sleep time, efficiency, serum renin and melatonin, while reducing sleep latency and cortisol.

缓解血管僵硬研究

Eases depression & anxiety*

Mg modulates neurotransmitters such as serotonin and dopamine to balance mood; deficiency may cause irritability and anxiety.

Research evidence on the substance L-Threonate magnesium

The efficacy marked with * has been partially substantiated by research, and effects may vary among individuals.
