Nighttime Supplements for Quality Sleep with ADHD (My Stack)

(My Current Stack I Use Nightly)

Sleep was one of my biggest ADHD struggles for years. Since building a consistent nighttime supplement stack, I fall asleep faster, sleep more deeply, and wake up feeling more restored.

My Nighttime Sleep Stack (Taken 30–60 min before bed)

Core supplements I take every night:

Magnesium Glycinate (300–400 mg) + Magnesium L-Threonate Calms the nervous system and supports deeper sleep.
Glycine (3–5 g) Helps me fall asleep faster and improves sleep quality.
GABA Quiets racing thoughts.
Myo-Inositol Supports calm and mood stability.
5-HTP Boosts serotonin (which helps with melatonin production).
Krill Oil with Astaxanthin Anti-inflammatory benefits that may support sleep over time.

What the Research Says (Quick Highlights)

Magnesium: Strong evidence linking magnesium deficiency to worse ADHD symptoms and sleep issues. Supplementation often helps with relaxation and sleep.
Glycine: Multiple studies show 3g before bed improves subjective sleep quality, reduces fatigue, and helps with next-day alertness.
5-HTP: May support sleep by increasing serotonin/melatonin.
Astaxanthin: Emerging research suggests it may help with sleep quality by reducing inflammation and oxidative stress, especially in people with higher stress or low mood.
