Sleep Support is one of our most popular products, and we think it's a genuinely useful formula for a lot of people. It's also the least fully-disclosed label in our lineup, and we'd rather tell you that directly than let you find out from a forum post. This is an honest, ingredient-by-ingredient look at what's actually in Sleep Support, where the dosing holds up, and where it doesn't — including a couple of things we think you should know before you take it.
What's actually on the label
Sleep Support has two parts. The first is a set of individually-dosed ingredients: Magnesium citrate, Vitamin B6, Calcium carbonate, and Melatonin at 10mg. Because these are individually dosed, you know exactly what you're getting from each one.
The second part is a 905mg "proprietary blend" containing 14 ingredients: L-Tryptophan, Lycium (goji berry), Chamomile, Lemon Balm, Passion Flower, L-Taurine, Hops, St. John's Wort, GABA, Chinese Skullcap, L-Theanine, Ashwagandha, Inositol, and 5-HTP. The label shows the blend's total weight, not what each ingredient contributes to it. That's a legal and common practice in supplements — and it's exactly the kind of formatting we're moving away from across our range. Sleep Formula, our other sleep product, already discloses every ingredient's individual dose; Sleep Support hasn't made that transition yet, and this post is partly about naming that gap plainly rather than glossing over it.
The melatonin dose is higher than what most research supports
Ten milligrams of melatonin sounds modest next to some of the mega-dose gummies on shelves, but it's well above the range that sleep-onset research typically studies. A 2024 dose-response meta-analysis of 26 randomized controlled trials found that melatonin's effect on sleep onset latency and total sleep time peaked around 4mg, with no added benefit shown at higher doses in the trials analyzed.1 An earlier meta-analysis of primary sleep disorder trials similarly worked from doses generally in the 0.3mg to 5mg range.2 The NIH's National Center for Complementary and Integrative Health notes that at doses above what the body normally produces, there isn't yet a clear picture of long-term safety.3
This isn't new information we're surfacing for the first time — Sleep Support's own product page already flags the melatonin dose and recommends talking to a doctor before use. This post is meant to reinforce that, not soften it. If you're melatonin-sensitive, take other medications, or you've never used a dose this high, that's worth a conversation with your doctor before you start, not after you notice next-day grogginess.
| Ingredient | Sleep Support label | Typically studied range (standalone) |
|---|---|---|
| Melatonin | 10mg | ~0.5–5mg for sleep onset; effect peaked near 4mg in meta-analysis1 |
| L-Theanine | Not disclosed (part of 905mg blend) | ~200–400mg in relaxation/sleep-quality studies |
| Ashwagandha | Not disclosed (part of 905mg blend) | ~300–600mg extract in most trials |
| 5-HTP | Not disclosed (part of 905mg blend) | ~50–100mg+ in most trials |
| St. John's Wort | Not disclosed (part of 905mg blend) | ~900mg/day standardized extract in most studied protocols |
The blend math doesn't work in most ingredients' favor
Here's the part we think matters most and gets glossed over most often in this industry: 905mg split across 14 ingredients averages out to about 65mg per ingredient if it were divided evenly. It almost certainly isn't divided evenly — proprietary blends are typically weighted toward whichever ingredients are cheapest, listed first, or most marketable — but even a generous, uneven split can't get most of these ingredients anywhere close to a full, typically-studied dose.
Look at the table above: L-theanine studies commonly use 200–400mg alone. Ashwagandha extract studies commonly use 300–600mg alone. Even a modestly-dosed ingredient like 5-HTP is usually studied at 50–100mg or more on its own. If any single ingredient in Sleep Support's blend is hitting one of those full research doses, it's taking up a large share of the 905mg total, which mathematically leaves very little room for the other 13. The honest read is that most of the 14 ingredients in this blend are almost certainly present at sub-clinical amounts — meaningfully below the doses used in the human research behind them.
A 14-ingredient, 905mg blend can list an impressive panel on the box. It can't give most of those ingredients a dose that matches the research behind them — the math simply doesn't allow it.
The interaction risk that's worth taking seriously
Two ingredients in this blend carry real, documented interaction risks, and we want to say this plainly rather than bury it in fine print: St. John's Wort and 5-HTP can interact with birth control, blood thinners, antidepressants, and anti-rejection medications.
St. John's Wort is a potent inducer of liver enzymes that metabolize many prescription drugs, which can make those drugs less effective — including hormonal birth control and warfarin-type blood thinners.4 The most serious documented cases involve organ transplant recipients: St. John's Wort has been linked to acute transplant rejection by speeding the clearance of anti-rejection drugs like cyclosporine, including a published case of acute heart transplant rejection in the medical literature.5 Separately, combining St. John's Wort or 5-HTP with SSRIs or other serotonergic antidepressants can raise the risk of serotonin syndrome, a genuinely dangerous condition — this isn't theoretical, it's been documented in published case reports involving a 5-HTP supplement and a prescribed antidepressant.67
If you're on hormonal birth control, a blood thinner, an antidepressant, or an anti-rejection medication, this is not a "check with your doctor" formality — talk to your doctor before taking Sleep Support. This is already noted on the Sleep Support product page, and we're repeating it here because it's a genuine safety point, not a footnote.
Why we're publishing this about our own product
The industry norm is to say none of this. Most proprietary-blend labels give you a total weight and a list of ingredients in descending order, and stop there — no dose math, no acknowledgment that a 10mg melatonin dose sits well outside the studied range, no flagging of interaction risk beyond the generic disclaimer everyone prints. We think that's the wrong standard, even when — especially when — the product in question is our own.
Sleep Support is exactly the kind of blend we're working to make more transparent over time, the same way we're approaching Cognitive Support. That work isn't finished, and we're not going to pretend it is just because the product sells well today. What we can do in the meantime is tell you clearly what's disclosed, what isn't, where the dosing looks reasonable, and where it doesn't — so you can make an informed call, and so your doctor can too.
Bottom line
Sleep Support works for a lot of people, and the individually-dosed ingredients on its label are exactly what they say they are. But the honest picture also includes a melatonin dose above the typically-studied range, a 14-ingredient blend that can't plausibly deliver full research doses of most of its components, and two ingredients with real prescription-drug interaction risk. None of that means don't use it — it means use it with the same information your doctor would want you to have. If you'd rather start with a formula that discloses every dose individually, Sleep Formula is our alternative built around that standard.
