Practices

The amount in a capsule can vary from bottle to bottle, and sometimes between capsules in the same bottle. Undeclared fillers have been found in them too.

This matters most when you are trying to work out whether something helps you. A good month followed by a flat one may be two different products…

Kava can damage the liver at a high enough dose, badly enough that some countries have banned it. Herbal is not a synonym for gentle.

The unnerving part is how quiet liver damage is. Someone self medicating anxiety with kava can be accumulating harm and feel nothing at all until it…

Vitamin C cannot really be stockpiled, since the excess leaves in your urine. A, D, E and K are stored in fat, so a large daily dose keeps adding to itself.

Vitamin D is where this bites at the moment, after a lot of people started taking big amounts on their own during the pandemic years. If you are…

Omega supplements thin the blood, so they usually do not belong alongside warfarin. Bruising easily is often the first thing anyone notices.

One clinician worked out that her husband's bruising came from taking omegas on top of his Coumadin, and it settled once his doctor told him to stop.…

If fish oil gives you those horrible repeats all afternoon, that is a fixable problem rather than a reason to stop. Keep the capsules in the freezer, ask about an enteric coated version, or try a flavoured liquid.

Sticking with something usually fails for small unglamorous reasons like this. Someone with a sensitive palate will not last four weeks with an…

Brain training games make you better at the game. Sadly, that improvement tends to stay inside the game.

Sorting shapes faster or planning a conveyor belt more smoothly comes from learning the task, not from stretching a capacity, so the classroom and…

The fair test for anything offered alongside medication is whether it adds something on top. In one small imaging study, cognitive training added to a stimulant left inhibition no better than the stimulant on its own.

Add on designs are unkind to hopeful ideas, which is exactly why they are worth running. About twenty children took part, so this is one small piece…

If someone has genuine positional vertigo, get it treated, and do not expect the treatment to touch their ADHD. Both things can be true at the same time.

Benign paroxysmal positional vertigo often follows a sinus infection or a bang to the head, and it responds well to repositioning manoeuvres that…

Sensory processing difficulties are real and worth accommodating, and they are not a standalone diagnosis. The proposal for one was turned down for lack of evidence that it stands apart from the conditions it appears with.

In practice it usually shows up alongside ADHD or autism, so it is best written up as a feature of the person: what they cannot tolerate, what they…

Turn the socks inside out so the seam sits away from the toes, cut the label out and print the size onto the fabric instead, and look at seamless clothing. These cost pennies against a course of therapy and they work by teatime.

A scratchy seam or a stiff tag is a small thing that keeps announcing itself all day, and every announcement takes a piece of attention with it.…

Since 1994, supplements have not had to satisfy a regulator before going on sale. Nobody checked the bottle in your hand the way they check a prescription.

The gap is wider than most people expect. Drug factories get unannounced inspections and can be shut down on the spot; supplement makers do not face…

Natural is not a regulated word: anyone can print it next to a picture of a leaf, on anything at all. Organic in the USDA sense does have a legal definition sitting behind it.

The same goes for the reassuring line about following good manufacturing practices, which describes what a company aims at rather than what an…

Kava, valerian, St John's wort, ginkgo, ginseng and the proprietary blends have not shown benefit for ADHD in trials that matched the amount in every capsule and kept both the person handing them out and the person rating behaviour unaware of who got what.

Those two design details are most of the story. Ordinary use has dose wobble and expectation running through it, and expectation is powerful,…

If a stimulant that was working suddenly is not, ask what else the person has started taking before deciding the dose needs to go up.

One woman's Adderall went flat while she was on a herbal supplement and came back to its usual self once she stopped it. Herbs can shift stomach…

If a little helps then a lot must help more is not really a supplement thought. It is an addiction shaped thought that has wandered into the vitamin aisle.

Moderation tends not to be a natural strength with ADHD, and this is one place where that costs something. Name it early, before a safe dose has…

People with ADHD tend to have lower omega-3 in their blood, and bringing low levels up has been linked with some improvement in symptoms. No convincing difference has shown up between DHA and EPA for this.

Omega-3 comes mostly from oily fish and krill, and fish is exactly what many people with texture sensitivity will not eat. Whether the shortfall…

In one trial, children were given omegas with a multivitamin, omegas alone, or neither, and after fifteen weeks everybody got both. The omega groups gained on set shifting and attention, and the children who started with nothing caught up once they crossed over.

Two features of that design are worth understanding. Everyone receiving the treatment eventually shows that the improvement follows the treatment…

Sixty two children took methylphenidate with either vitamin D or a placebo, and both groups improved. The two ADHD rating scales showed no difference between them, which leaves the positive headline resting on the clinician's judgement rather than on what parents reported.

That shape repeats all over this literature, so it is worth learning to spot. When a study reports an effect on one measure and not another, the…

People with ADHD are reported to run low on both tryptophan and homocysteine. Low homocysteine is a good thing to have, since it is the high version that damages hearts.

The reflex to correct any number under the reference range is worth resisting. Levels can be tested where there is a reason to test them. Eating a…

Omega supplementation for ADHD began with encouraging results, including a Swedish study where about a quarter of inattentive children seemed to improve. Blinded, placebo controlled work did not reproduce it, and a Cochrane meta-analysis found no effect.

The manufacturers themselves largely moved on to other conditions, which tells you something. None of this makes omegas worthless, and levels do run…
