Best ADHD Supplements in the UK: What Actually Works (2025 Guide)

Why Supplements Matter for ADHD

ADHD isn’t just about focus — it can affect mood, energy, sleep, and emotional regulation. While medication is life-changing for many, nutritional deficiencies are often overlooked — even though they play a crucial role in brain health.

Whether you're managing ADHD with or without medication, the right supplements can support:

Dopamine production

Gut-brain communication

Executive function and mental energy

Calm, clarity, and sleep


What to Look for in a High-Quality ADHD Supplement

Here are the top research-backed ingredients to look for in any ADHD supplement:

🧠 Magnesium Glycinate

Helps improve sleep and muscle relaxation

Glycinate is gentle on digestion and highly absorbable

Iron & Zinc
