Not all forms of magnesium are equal. Magnesium oxide — the most commonly sold form in pharmacies — is only absorbed at around 8% by your body. The rest passes through without ever reaching your nerve cells.

Bisglycinate, on the other hand, is bound to glycine — an amino acid that your cells recognise and absorb directly. The result: bioavailability of up to 64%, which is 8 times more. That's why so many people take magnesium every evening without ever feeling a difference: the problem isn't the magnesium. It's the form.

Some people feel a calming effect from the very first nights. For others, it takes one to two weeks — the time your body needs to replenish its stores.

Magnesium contributes to normal nervous system function and normal muscle function, but every body has its own rhythm. That's exactly why our guarantee covers 60 full nights: the time you need, without any pressure.

We understand. You may have already tried several things. That's exactly why we offer a 60-night guarantee, with no proof required.

If after two months you feel no difference, we'll give you a full refund. You have nothing to lose — only calmer nights to gain.

Magnesium bisglycinate is one of the best-tolerated forms, precisely because it does not cause the typical laxative effect of magnesium oxide. No known dependency. No artificial drowsiness like with melatonin.

It's an essential mineral your body already uses every day — Purylin simply gives it the form it can truly use.

In the evening, your nervous system should naturally wind down to prepare for sleep. When magnesium is lacking — or not properly absorbed — muscles remain contracted and the nervous system stays on alert at the very moment it should be relaxing.

It's precisely this unregulated nerve signal that manifests as restlessness in the legs. The glycine bound to bisglycinate helps reduce this nerve excitability.

Magnesium bisglycinate generally combines well with most everyday supplements. However, if you are following a medical treatment, we always recommend speaking with your doctor or pharmacist before adding it to your routine — as a simple precaution, not because any particular known risk exists.

The Discovery Pack (7 nights) is perfect for a light introduction. The 60-night Pack is our best-seller — it's the time generally needed to feel the full benefits, and includes free delivery.

The 90-night Pack goes further with a complete PDF guide included. In all cases, you're covered by our 60-night guarantee.

One capsule, in the evening, before bed. That's it. No complicated dosage calculations, no new routine to learn. You simply add it to what you're already doing before you sleep.

By selling directly, without intermediaries or pharmaceutical distribution margins, we can use a higher-quality form of magnesium — bisglycinate — at a fair price, rather than the cheap oxide found on most pharmacy shelves.

Women in perimenopause and menopause are among the profiles most commonly reporting increased leg restlessness in the evening, linked to hormonal fluctuations. Magnesium bisglycinate fits naturally into an evening routine during this period of life, with no hormones or controversial ingredients.

Simply contact us, with no proof required, within 60 nights of your purchase. It's that simple. We'd rather refund you than leave you with a product that doesn't suit you.

Your order is dispatched quickly after confirmation. You receive a tracking number to follow every step until it arrives at your door.
