Sleep & Recovery: A South African Apothecary's Guide

If you're reading this at 1 a.m. on your phone, you already know the problem. Bad sleep isn't a personality flaw — it's a downstream signal that something in the body is mistuned. This guide is what 30 years on the health store floor in Centurion has taught us about what actually helps, in what order, and what's just clever marketing.

Who this guide is for

If you fall asleep fine but wake at 3 a.m. with a racing mind; if you take 90 minutes to drift off; if you sleep through but wake unrested; if you're on shift work, peri-menopause, or just a stressful year — this is for you. If you've been sleeping badly for more than three weeks straight, this guide is the first step but not the last (more on that further down).

The short version

• Magnesium glycinate at 300–400 mg, 60 minutes before bed — quiets the nervous system and is the closest thing supplements have to a reliable foundation.
• Glycine at 3 g — drops core body temperature, which is the actual physiological trigger for sleep onset.
• Ashwagandha at 300–600 mg of a standardised extract (KSM-66 or Sensoril) — lowers cortisol over weeks, not minutes.
• 5-HTP at 50–100 mg — only if mood is also low. Not a sleeping pill.
• Melatonin at 0.3–1 mg (not 5 mg) for circadian reset — useful for jetlag and shift work, less useful for ongoing insomnia.

Below is the longer version, in the order we'd discuss it with you in the store.

What we actually know about sleep

Sleep is a two-system problem: a circadian rhythm (when you sleep) and a homeostatic drive (how badly the body needs sleep). Most supplements act on one or the other — none act on both. That's why people who switch from melatonin to magnesium and back keep failing: they're solving the wrong system.

If you can't fall asleep, you have a sleep-onset problem. If you wake at 3 a.m. and stay awake, that's a sleep-maintenance problem (often cortisol-driven). If you sleep eight hours but feel unrested, that's a sleep-quality problem (often magnesium, sleep apnoea, or alcohol). Different problems, different stacks.

The foundation: magnesium

You will see magnesium in every sleep stack we recommend, and there's a reason. Magnesium is a co-factor in over 300 enzymatic reactions, including the ones that regulate GABA — the brain's main calming neurotransmitter. South African soils are increasingly magnesium-depleted, and the average diet here delivers maybe 60% of the daily target. Most people are walking around mildly deficient and don't know it.

The form matters. Magnesium oxide (the cheap supermarket kind) is poorly absorbed and tends to cause diarrhoea. Magnesium citrate is better. Magnesium glycinate (also sold as bisglycinate) is the one we actually keep at the front of the shelf for sleep — it crosses the blood-brain barrier and the glycine itself is calming. Start at 200 mg an hour before bed and build to 400 mg over a week.

What we take ourselves: 400 mg magnesium bisglycinate an hour before bed, with a glass of water. We notice the difference in our 3 a.m. wake-ups within a week.

Glycine — the quiet underdog

Glycine isn't trendy, which is why it works. Studies dating back to 2007 show 3 g of glycine before bed reduces sleep-onset latency and improves next-day alertness. The mechanism is unglamorous: it lowers core body temperature, which is the actual signal your body uses to know it's time to sleep. If you've ever noticed you sleep better in a cold room, this is why.

You can take it as a powder dissolved in water (slightly sweet, easy to drink). It pairs well with magnesium glycinate — they don't compete, they compound.

What we take ourselves: 3 g of glycine powder in the same glass as the magnesium. Tastes faintly sweet, doesn't need flavouring.

Ashwagandha — for the 3 a.m. wake-up crowd

If your problem is waking at 3 a.m. with a racing mind, magnesium and glycine alone usually aren't enough. That pattern is almost always cortisol — the stress hormone that should be lowest at midnight is spiking too early. Ashwagandha (Withania somnifera) is the most researched adaptogen for this. KSM-66 and Sensoril are the two standardised extracts with the best clinical data. 300–600 mg daily, taken in the morning or with dinner.

One caveat: ashwagandha works on the HPA axis over weeks. You'll see real benefits at the 3–4 week mark, not the next day. People give up on day five and conclude it doesn't work. It does — give it a month.

What we keep on the shelf: KSM-66 is our default — 300 mg twice a day for the first month, then 300 mg once a day after. Sensoril is the alternative for people who do better with the evening-only dose.

5-HTP — for the mood-and-sleep overlap

5-HTP is a precursor to serotonin and then melatonin. If your sleep problem comes with low mood, irritability, or PMS, 5-HTP at 50–100 mg in the evening is worth trying. Don't combine it with prescription antidepressants without checking with your doctor — there's a serotonin-syndrome risk that's rare but real.

Melatonin — what people get wrong

Melatonin is sold in 3 mg and 5 mg doses, which is roughly 20× the dose your body actually uses. At those levels, melatonin overshoots and you wake up groggy. The clinical-trial dose for circadian shift is 0.3–1 mg, taken 4–5 hours before your target sleep time, not at bedtime. If you're using melatonin and feeling worse, this is usually why.

Melatonin shines for jetlag, shift work, and resetting a wrecked sleep schedule. It doesn't shine for ongoing insomnia — you adapt to it within weeks.

What we'd suggest: if a customer asks for melatonin without travel or shift-work in their day, we usually walk them back to magnesium first. The melatonin shelf is small and stays small on purpose.

What's overhyped

• CBD for sleep — mixed evidence, expensive, often under-dosed in retail products.
• Valerian — works for some people, smells terrible, and the studies are mostly mediocre quality.
• Sleep gummies with 10 ingredients — usually too little of anything to matter.
• L-tryptophan as the headline ingredient — it doesn't cross the blood-brain barrier well on its own.

When this isn't a supplement problem

Supplements are not the answer if any of the following apply: you snore loudly and wake gasping (suspect sleep apnoea); your insomnia started suddenly without a clear trigger; you're on antidepressants, blood thinners, or thyroid medication; you're pregnant or breastfeeding; you've been sleeping badly for more than six weeks. In those cases, supplements may help but the underlying issue needs proper diagnosis. Our store consultants will tell you the same thing — we'd rather refer you out than sell you something that won't work.
