<p><em>For the nights that won't switch off — and the mornings that pay for it.</em></p>

<p>If you're lying awake with a racing mind, waking through the night, or sleeping a full eight hours and still surfacing tired — the problem usually isn't that you need to "try harder" to sleep. It's that the pathway your body uses to wind down isn't being given what it needs.</p>

<p>This stack supports that pathway from two directions at once.</p>

<p>Sleep is the end of a chain that starts hours earlier. Your body builds serotonin during the day, then converts it to melatonin at night to signal rest. That conversion needs raw materials and the right minerals to run smoothly. Stress, poor diet, and modern life quietly drain both. The Sleep Stack is built to support the chain rather than knock you out — so your body does the work, the way it's meant to.</p>

<h2>What's inside</h2>

<h3>HTP-5 — sleep &amp; mood</h3>
<p>5-HTP is the precursor your body uses to produce serotonin, which it then converts to melatonin overnight. Paired with the cofactors your body needs to make the conversion, HTP-5 supports your body's own natural wind-down process rather than overriding it.</p>

<h3>Double Magnesium — deep sleep &amp; relaxation</h3>
<p>Magnesium supports the nervous system's shift from "alert" into "rest," and many UK adults run lower on it than they'd like — particularly during stressful stretches. Taken in the evening, it helps set the conditions for a calmer night.</p>

<h2>Why these two together</h2>

<p>HTP-5 supports the production side of the sleep pathway; magnesium supports the relaxation side. One gives your body the building block, the other helps your nervous system actually use it. Together they're designed for people whose sleep struggles sit alongside daytime stress — the classic "tired but wired" pattern.</p>

<p>Used consistently alongside the basics — a proper wind-down routine, less late caffeine, a dark cool room — they give your body a fuller set of tools to rest.</p>

<p><strong>No stimulants. No sedatives. No proprietary blends.</strong> Made in the UK to GMP standards, and backed by our money-back guarantee.</p>
