Hypnozan 8H Program is not one supplement but two, taken at different points of the evening: a magnesium bisglycinate capsule after dinner and a botanical capsule half an hour before bed. It is sold only on the brand’s own site, so instead of a customer-rating sample we ran a 30-day trial ourselves.
What is in the two bottles
The physical label matches the website, which is the first thing we check and the thing that most often fails.
The magnesium side gives 200 mg of elemental magnesium from bisglycinate in two capsules, with 4 mg of vitamin B6. Printing the elemental figure rather than the compound weight is worth noting: a great many magnesium products lead with a number like 1,800 mg, which is the weight of the salt rather than the mineral inside it. Here the number on the label is the number that matters.
The botanical side lists valerian root extract, lemon balm, motherwort and hops, each quantified twice — once for a single capsule and once for two — alongside B6 and B12. There is no proprietary blend anywhere on either product.
One gap, and it is the reason transparency does not score higher. The botanical extracts are listed in milligrams with no extract ratio. A 100 mg valerian extract at 4:1 and a 100 mg extract at 10:1 represent very different amounts of plant material, and without that ratio the figure cannot be compared to anything — not to research, not to a competitor, not to a herbal medicine on a pharmacy shelf. For a label that gets everything else right, its absence stands out.
The pack carries a batch number and a September 2029 expiry. A certificate of analysis for this specific batch was not supplied; the site publishes a general Agrolab certificate, which speaks to the manufacturer’s practice rather than to the box we opened.
Is the dose right
For the magnesium half, yes. The published trials on magnesium and sleep are small and few, but the most relevant recent one used 250 mg of elemental magnesium as bisglycinate daily for four weeks and reported a modest improvement in insomnia severity scores against placebo. A pooled analysis of the three randomised trials available found sleep onset shortened by roughly 17 minutes, on evidence the authors themselves rated low quality. At 200 mg this product sits just under the trial dose and comfortably inside the 400 mg the NHS considers unlikely to cause harm from supplements.
That last point matters more than it looks. Because this is a 200 mg dose rather than the 380 mg some products carry, it leaves room for magnesium arriving from a multivitamin or an electrolyte drink, which the higher-dose products do not.
For the botanical half we cannot say. Without the extract ratio there is no honest way to compare 100–200 mg of valerian to the doses used in research, and motherwort in particular has little human sleep evidence behind it in any amount. This is not a mark against the formula — it is a question the label leaves unanswered, and we have scored it as unknown rather than as a shortfall.
Why it is split in two
Most sleep supplements are a single capsule taken once. This one asks for two products at two different times: magnesium with food after dinner, botanicals on an empty stomach half an hour before bed.
There is a logic to it. Magnesium is better tolerated with food, while the botanicals are aimed at the wind-down and are timed accordingly. Splitting them also allows larger amounts of each than would fit in one capsule taken once.
Whether that is worth the extra step is a personal question. It is two bottles, two moments, and one more thing to remember on a tired evening — and it is the main reason practicality does not score higher.
Our 30-day trial
The trial ran for 30 days across July and August 2026, following the label exactly: two magnesium capsules after dinner, one to two botanical capsules half an hour before bed. The product was bought through the site’s subscription plan.
The pack arrived sealed the day after ordering. Capsules were odourless and tasteless, no digestive discomfort appeared at any point in the month, and the timing never had to be adjusted around meals. The 30-day pack lasted exactly the 30 days promised, which is worth saying because supplements sold as a month frequently run out in three weeks. The subscription was clearly separated from the one-off purchase at checkout and cancelled without friction through the link in the order email.
Verdict
- Works
- The product does what it promises
- Elemental magnesium printed rather than compound weight
- No proprietary blend — every active quantified twice
- Batch number and long expiry on the pack
- Dose leaves room for magnesium from other sources
- 30 days of supply against 30 days promised
- Subscription clearly labelled and easy to cancel
- Doesn’t
- Two bottles and two timings every evening
- Sold on one website only
Worth it if you want a fully quantified label with no blend, you prefer a moderate magnesium dose that leaves headroom for other sources, and the two-step evening routine does not bother you.
Skip it if you want one capsule rather than two products, if you are buying primarily for the magnesium — a standalone bisglycinate costs a fraction of this — or if you need to know the strength of a herbal extract before you take it.
Check with a pharmacist before taking it alongside prescription sedatives or other sleep medication. The manufacturer states it should not be combined with alcohol or sedative drugs.
How we score
Every supplement in this section is judged on the same six criteria, weighted as below. We score the product that left the factory — the formula, the dose, the pack — not the way a retailer has written the listing. Marketing wording is worth pointing out, and we do, but it does not move the score.
Each criterion is scored out of 10 against the norm for its category, not against an ideal: 10 is best practice, 8 solid with minor gaps, 7 neutral or not verifiable from the evidence available, 6 works but with a real limitation, 4 a serious shortfall, 2 should not be on the shelf. The overall figure is the weighted average, printed to one decimal place, and the paragraph under the table explains where the marks went.
