Working out what you have comes before choosing what to take. The right remedy for the wrong condition is still the wrong remedy, however good the remedy happens to be.

The health food shop route usually starts with a self diagnosis, and that first step is the one worth slowing down. St John's wort will do nothing for a vitamin D deficiency that is showing up as low mood, whatever it does for depression. Get the question right, then argue about the answer. It matters for safety too, since several supplements interfere with prescribed medication.

Qur’an and Sunnah

Would you exchange better for worse? (Quran 2:61). The question is put to people who traded what was doing them good for what they fancied instead.

وَإِذۡ قُلۡتُمۡ يَٰمُوسَىٰ لَن نَّصۡبِرَ عَلَىٰ طَعَامࣲ وَٰحِدࣲ فَٱدۡعُ لَنَا رَبَّكَ يُخۡرِجۡ لَنَا مِمَّا تُنۢبِتُ ٱلۡأَرۡضُ مِنۢ بَقۡلِهَا وَقِثَّآئِهَا وَفُومِهَا وَعَدَسِهَا وَبَصَلِهَاۖ قَالَ أَتَسۡتَبۡدِلُونَ ٱلَّذِي هُوَ أَدۡنَىٰ بِٱلَّذِي هُوَ خَيۡرٌۚ ٱهۡبِطُواْ مِصۡرࣰ ا فَإِنَّ لَكُم مَّا سَأَلۡتُمۡۗ وَضُرِبَتۡ عَلَيۡهِمُ ٱلذِّلَّةُ وَٱلۡمَسۡكَنَةُ وَبَآءُو بِغَضَبࣲ مِّنَ ٱللَّهِۚ ذَٰلِكَ بِأَنَّهُمۡ كَانُواْ يَكۡفُرُونَ بِـَٔايَٰتِ ٱللَّهِ وَيَقۡتُلُونَ ٱلنَّبِيِّـۧنَ بِغَيۡرِ ٱلۡحَقِّۚ ذَٰلِكَ بِمَا عَصَواْ وَّكَانُواْ يَعۡتَدُونَ

Remember when you said, ‘Moses, we cannot bear to eat only one kind of food, so pray to your Lord to bring out for us some of the earth’s produce, its herbs and cucumbers, its garlic, lentils, and onions.’ He said, ‘Would you exchange better for worse? Go to Egypt and there you will find what you have asked for.’ They were struck with humiliation and wretchedness, and they incurred the wrath of God because they persistently rejected His messages and killed prophets contrary to all that is right. All this was because they disobeyed and were lawbreakers

What the research says

Even well supported treatments depend on who is taking them. Across randomised trials, omega-3 supplementation reduced depressive symptoms, with the benefit concentrated in people with diagnosed depression rather than in healthy volunteers. Same compound, same dose, and the effect largely disappears when the condition is not there.

Strength of evidence: one line of research. A single study, or a theoretical account.

Why it works

A treatment can only act on the thing it acts on, so getting the problem wrong makes the rest of the decision irrelevant.

When not to

Tell your prescriber about anything you buy over the counter, since St John's wort in particular interferes with a number of medications.

This one is still a draft. It is waiting on a scholar and a clinician to read it before it is published.
