Melatonin, magnesium, ashwagandha, GABA, L-theanine, and more. After 7 months of sleep testing, here's what I actually recommend.
The Health Guy's Rating
I'm a bad sleeper. Always have been. Mind races at night, wake up at 3am, stare at the ceiling doing mental math on how many hours of sleep I'll get if I fall asleep right now.
So I decided to be systematic about it. For 7 months, I tested one sleep supplement per month. I tracked sleep with an Oura Ring throughout, so this isn't just vibes — I have the data.
Here's everything I found.
My baseline numbers:
My Rating: 9.0/10
If you take nothing else from this article, take this: magnesium glycinate is the real deal.
After 30 days on 400mg of magnesium glycinate (taken 30-60 min before bed):
These numbers are actually significant. Magnesium is involved in hundreds of enzyme reactions and most adults are genuinely deficient. It activates GABA receptors (the calming neurotransmitter), regulates cortisol, and helps muscles relax.
The glycinate form matters — glycine itself has calming properties and the glycinate chelate form has better bioavailability and is gentler on the stomach than magnesium oxide (the cheap stuff).
Recommendation: Thorne Magnesium Bisglycinate or Doctor's Best Chelated Magnesium. ~$25-35/month.
My Rating: 8.5/10
L-theanine is an amino acid found in green tea. It promotes alpha brainwave activity — the same state you're in during meditation. Calmer, not sedated.
My results were surprisingly good:
The biggest benefit was subjective: I felt less wired at bedtime. For people whose sleep issues come from racing thoughts and anxiety, L-theanine is excellent.
Dose: 200mg. I stacked it with magnesium glycinate and the combo was even better than either alone.
Recommendation: Now Foods L-Theanine or Jarrow L-Theanine. ~$15/month.
My Rating: 8.2/10
Ashwagandha doesn't work the same night — it's a cumulative adaptogen. By week 3, though, I noticed a real shift. My HRV improved significantly (from 52ms to 64ms average), I was less reactive to stress during the day, and bedtime felt less like fighting my brain.
Results:
The mechanism: ashwagandha lowers cortisol and has anxiolytic effects. If stress or anxiety is driving your sleep problems, this is the supplement for you.
The KSM-66 branded extract is what's used in most clinical trials — don't settle for generic ashwagandha powder.
Recommendation: Jarrow KSM-66 Ashwagandha or Nootropics Depot. ~$25/month.
My Rating: 7.0/10
Here's the thing about melatonin that nobody tells you: you're probably taking too much of it.
Most melatonin products are 5-10mg. Research suggests 0.3-0.5mg is actually the effective dose for most people. Taking 10mg isn't "more effective" — it floods your receptors and can actually make sleep quality worse while also causing morning grogginess.
My results with 0.5mg (I cut tablets):
Melatonin is excellent for resetting your circadian rhythm — jet lag, shift work, or getting your schedule back on track. For chronic insomnia, it's less effective than magnesium or ashwagandha.
Recommendation: Pure Encapsulations Melatonin 0.5mg. Use it for schedule correction, not every night.
My Rating: 5.5/10
GABA is the brain's main inhibitory neurotransmitter. In theory, supplementing it should calm the nervous system and improve sleep. In practice, GABA doesn't cross the blood-brain barrier well when taken orally.
My results were minimal. Some people swear by it, but I think those results are mostly placebo or may involve a different mechanism. The Pharma GABA form has slightly better evidence but still underwhelming.
If you want to support GABA activity, L-theanine and magnesium glycinate do it better.
My verdict: Skip it. Spend the money on better-evidenced alternatives.
My Rating: 6.5/10
Valerian has been used as a sleep aid for thousands of years. Clinical evidence is mixed to positive. My personal results were mild — some reduction in sleep latency but nothing dramatic.
The big downside: it smells and tastes terrible. The capsules are fine but valerian tea is genuinely challenging.
If you want something herbal and prefer to avoid more potent options, it's a reasonable choice. I just didn't find it compelling compared to magnesium.
My Rating: 7.8/10
Phosphatidylserine (PS) is a phospholipid that supports brain cell membrane integrity. More relevant here: it reduces cortisol in response to physical and psychological stress.
This one surprised me. By week 2 I noticed significantly reduced mental chatter at bedtime. Sleep latency improved by about 25% and my HRV improved. It's particularly good if your sleep issues are tied to overtraining, work stress, or high cortisol.
The downside: it's expensive. A quality 100mg/day dose runs ~$40-50/month.
Recommendation: Jarrow Formulas Phosphatidylserine or Swanson PS.
After all this testing, here's what I actually use now:
Nightly (30-60 min before bed):
Ongoing:
Total cost: ~$55-70/month. Significantly better results than anything I spent on sleep aids before.
For melatonin: I keep 0.5mg on hand for travel and schedule resets, but I don't use it every night.
