Very low vitamin D produces fatigue, low mood and a flatness that looks exactly like depression, and it is not part of routine bloods in most places. If you have never had it measured, it is a fair thing to ask for.

One clinician telling this story about himself had a level that was almost undetectable, and no antidepressant would have raised it, because what was…

The vitamin D in a general multivitamin is a maintenance amount, nowhere near what is used to correct a real deficiency. If your level is genuinely low, that is a prescribing conversation with blood tests behind it, not a shelf in the chemist.

Correcting a deficiency usually means a high dose for a defined period and then a steady daily amount, with the level rechecked to see where you have…

Before settling on depression as the whole story, ask for thyroid function and vitamin D to be checked. Both are common, both are cheap to test, and an underactive thyroid produces a picture that looks like depression from the outside.

An untreated thyroid problem also blunts how well antidepressants work, so missing it can mean months on a treatment that was never going to do the…

If a health habit keeps sliding, attach something immediate to it. The apps where you put real money on hitting a step target work for a reason: the payoff arrives now instead of in twenty years.

The natural reward for walking more is invisible and decades away, which is no use to a brain running on what happens next. A small stake, a streak,…

Before settling on a purely psychological account of months of anxiety or broken sleep, it is worth having the ordinary bloods done. Low iron, low vitamin D or low magnesium can produce symptoms that look exactly like a mental health problem.

This is not about swapping therapy for supplements. It is about not spending a year working on something a blood test could have partly explained. If…

A child struggling with attention, anxiety and daily reflux at once may be dealing with one problem wearing three coats. Undiagnosed coeliac disease and other food reactions can produce all of it, and the gut symptom is the clue worth following.

Symptoms that arrive together are worth asking about together. If reading, mood and stomach all went wrong over the same period, that pattern is…

If you are testing whether a food affects you or your child, the test has to be complete. Among children with suspected sensitivity to artificial colouring, most reacted to as little as 100 mg, so a bit left in is enough to blur the answer.

What usually happens is that a family removes the obvious sources, misses the ones hidden in medicines, sauces and cereals, sees no change, and…

Cutting artificial preservatives out can genuinely help a child who reacts to them, because a child who feels unwell behaves worse. What it does not do is treat the ADHD underneath, which will still be there once they feel better.

Worth being clear with yourself about what you are hoping for, because these diets are expensive and hard to keep up. If your child does have…

Gluten free and dairy free eating is essential in coeliac disease and in a genuine milk allergy. Neither one treats ADHD, and putting a child on them without a reason carries costs of its own.

The cost is not only money and nutrition. It is the birthday party where they cannot have the cake and the lunch table where their food is different…

If you are going to test whether a food matters, work out in advance where the plan will leak. School lunch swaps, a grandparent's biscuit tin, your own memory on a hard week: all of it decides whether the answer means anything.

Change one thing at a time and keep everything else steady, otherwise you cannot tell which change did what. Then be honest about who is running the…

If your body has something going on as well, try to get both looked after at the same time rather than in a queue. Therapy for what happened to you does not have to wait for your gut to settle, and it often goes better when the two run side by side.

Plenty of people park the physical thing while they do the psychological work, or the other way round, then wonder why progress keeps sliding back. A…

Low mood that arrives with bloating, fatigue and a foggy head is worth looking at from the food side too. An immune reaction to something you eat regularly can produce all three, and it gets labelled depression far more often than it gets tested.

The point is not to start cutting foods out on a hunch. It is to say the possibility out loud to a doctor, particularly if the gut symptoms and the…

When something has gone wrong across several systems, expecting one treatment to fix it is usually the mistake. Movement, processing what happened, changes to food and work on calming the body tend to add up in a way that none of them manages alone.

This is not an argument for doing everything at once until you are exhausted. It is an argument against giving up on the whole idea when the first…
