Overview

This episode explores the most vital nutrients for optimizing brain health in women with ADHD, delving deep into the connections between nutrition, hormones, mood, and neurodivergent wellbeing. Host Kate Moryoussef and guest Lucinda Miller (naturopath and bestselling author) blend science-based advice with lived experience—discussing how targeted dietary choices, supplements, and gentle lifestyle tweaks can dramatically improve cognitive function, mood regulation, and everyday life for women and girls with ADHD and related neurodivergent conditions.

Key Discussion Points & Insights

1. Lucinda Miller’s ADHD Journey

• Personal Experience: Diagnosed at 31 after observing symptoms post-pregnancy and inspired by her husband’s diagnosis ([02:14]).
• Early Approaches: Initially avoided medication due to pregnancy and limited information; sought out dietary and nutritional solutions as a trained naturopath ([02:14]).
• Midlife Challenges: Struggled in her 40s with memory, word retrieval, and overwhelm—coinciding with thyroid issues (Hashimoto's) and perimenopause ([04:02]).
• Quote:
  “I found it incredibly hard to manage my life...my brain wasn't being fed with those amino acids.” – Lucinda ([02:40], [06:55])

2. The Science of ADHD, Hormones, and Neurotransmitters

• Dopamine & Estrogen:
  • Dopamine is key for ADHD brains. Estrogen affects dopamine reuptake, especially during hormonal changes (teens, pregnancy, perimenopause/menopause) ([06:06]).
  • “When our estrogen is changing...oestrogen is really important for that reuptake of dopamine, which is what the medication does.” – Lucinda ([06:18])
• Protein & Tyrosine:
  • Tyrosine (amino acid in protein-rich foods) builds dopamine. High-protein breakfasts are essential for stable energy and focus ([06:36], [07:10]).
  • “The most important change that I personally made was switching to a very high protein breakfast... otherwise my brain went to mush.” – Lucinda ([07:22])

3. Iron: The ADHD Game-Changer

• Importance of Iron:
  • Essential for converting tyrosine to dopamine; most ADHD women and girls are iron-deficient ([08:50]).
  • Ideal ferritin (iron stores) for ADHD brains: 70-100 (higher than standard NHS ranges) ([08:50]).
  • “Most women we see...are often at 12, 13, 14, 15, 16—super low. So they're almost on the edge. There just isn't enough iron to convert that tyrosine into dopamine.” – Lucinda ([08:57])
• Iron Supplementation:
  • Typical iron intake from food (e.g., steak) often insufficient; supplements frequently needed.
  • Differences between types (Spatone liquid, beetroot-based capsules, tablets); absorption issues with gut problems ([10:32]-[13:05], [13:06]).
  • “There are lots of people who may think they might have ADHD, but it may just be low iron.” – Lucinda ([13:46])
  • Personal anecdote: Brain clarity returned when ferritin hit 70–80 ([13:53]).

4. Zinc: The Mood & Sensory Mineral

• Functionality:
  • Second most abundant CNS mineral. Impacts dopamine and GABA synthesis, calmness, sleep, anxiety, immunity, and emotional regulation ([14:37]).
  • “Zinc can help with mood swings...this emotional dysregulation is all over the shop, then sometimes it's a high need for zinc.” – Lucinda ([15:23])
• For Selective Eaters:
  • Zinc drops/sprays are practical; can lead to more curiosity around food and gradual dietary expansion. Hide in juices, apple sauces etc. ([17:23]).
  • Sneaky nutrition strategies: add zinc- & iron-rich ingredients into favourite foods (e.g., brownies, pasta, pesto) ([17:23]-[20:00]).
  • “You could bake with them at the weekend...there are ways of getting things in through crunchy, beige, chocolatey things.” – Lucinda ([18:55])

5. Adapting Nutrition as Overwhelmed Parents

• Importance of realistic progress ("drip feed" changes rather than total overhaul) ([16:23], [38:28]).
• Engage kids in choosing and making recipes—foster control and positive associations ([18:55], [38:28]).
• “Even for someone like us who knows quite a bit, it's really overwhelming...do what you can, when you can." – Kate ([16:25])

6. Saffron: The Natural Calmer

• Supplement Praise:
  • Acts as an adaptogen—lowers anxiety, balances hormones. Shown to be as effective as certain ADHD meds for some individuals ([25:36]-[26:12]).
  • Especially supports premenstrual and perimenopausal anxiety, mood swings ([27:09]).
  • “Saffron helps to bring that right down...it has been used compared with methylphenidate and found to be as effective without the side effects.” – Lucinda ([25:40])

7. GABA: The Anti-Anxiety Neurotransmitter

• Role:
  • Calms the brain, reduces risk-taking and repetitive thoughts, improves sleep ([28:10]-[28:36]).
  • Deficiency linked to anxiety, OCD, and impulsivity ([28:36]-[29:57]).
• How to Support GABA:
  • Supplements: GABA not over-the-counter in UK, but L-theanine (from green tea), magnesium, zinc, B6, and certain cheeses (Gouda, Emmental) all help ([29:57]-[31:23]).
  • Lifestyle: Epsom salt baths, exercise, yoga, meditation, time in nature ([31:23]-[34:00]).
  • “Even small amounts really count.” – Lucinda ([34:07])

8. Minimizing Glutamate (Anxiety Trigger)

• Glutamate in Ultra-Processed Foods:
  • Heightens anxiety and dysregulation; frequently hides in natural flavourings, yeast extract ([32:57]-[34:00]).

9. Melatonin: Sleep, Pain & Inflammation

• Optimizing Naturally:
  • UK: melatonin available only by prescription.
  • Natural supports: Avoid screens before bed; eat cherries (all forms), tryptophan-rich foods (turkey, chicken, bananas, cashews, avocados) ([35:31],[38:04]).
  • Homemade “sleepy cherry smoothie” recipe is a highlight (helped many ADHD/autistic children sleep through the night) ([37:24]-[38:04]).
  • “Optimizing melatonin, so optimizing your sleep, could well help with your pain.” – Lucinda ([35:31])

10. Self-Compassion & Empowerment

• Incremental changes count; there’s no such thing as perfect nutrition.
• Free/affordable steps matter (e.g., Epsom salt baths, mindful moments, single recipe at a time) ([38:28]-[42:00]).
• Importance of parent modelling & legacy—kids will remember holistic health skills taught at home ([42:20], [43:50]).
• “The right nutrition helps how you feel and not who you are. You’ll still have your ADHD, you’ll still be yourself, but you’ll just all feel so much better and live a better life.” – Lucinda ([42:02])

Notable Quotes & Moments

• On the societal and personal impact of memory and executive function losses in midlife: "If we're perceived as scatty or chaotic or disorganized, that has a huge impact on our confidence." – Kate ([05:03])
• On nutritional hope and empowerment: “If we can spend £20 or so on your book, that is giving us the tools and ammunition to reclaim a bit of control.” – Kate ([41:45])
• On navigating overwhelm: “Do what you can, when you can... just start with little things—cherry smoothie, bliss balls. We can feel that we are doing something.” – Kate ([38:28])
• On holistic healing vs. medication: “It has been used (saffron), compared with methylphenidate, and found to be as effective without the side effects.” – Lucinda ([25:40])
• On why nutritional investigations can help neurodivergent individuals: “We spend lots of time with you... discussing your diet, your life, what your issues are, what you'd like to get better... it gives you a really good snapshot of what is going on right now and which areas are priority.” – Lucinda ([44:04])
