Many people with focus and attention challenges are looking for the same thing: clearer thinking without feeling overstimulated, and calm without feeling flat.
We spoke with Jane McKenzie-McHarg, Naturopath, Nutritionist & Herbalist, about how she approaches ADHD and attention regulation in practice.
The Nervous System First
Jane explains that focus is closely linked to how well the nervous system is supported.
“Mental clarity relies on nervous system balance, optimal nutrition and healthy circulation. Magnesium, B-vitamins and herbal adaptogens can support cognitive performance, especially during periods of stress or hormonal change.”
Attention improves when the whole body is regulated and well nourished. Stress, nutrient depletion, and nervous system overload can all make focus harder to access, particularly for people with ADHD traits.
Supplements to support focus and calm
Jane focuses on nutrients and herbs that support both brain chemistry and nervous system regulation:
- Omega-3 fatty acids to support brain structure and communication
- Magnesium to support nervous system and stress response
- L-theanine to promote relaxed focus without sedation
- Saffron for mood support and cognitive balance
