We built this because we needed it ourselves.

Our founder had struggled with poor sleep and chronic stress for years. Despite trying melatonin, sleep apps, and expensive supplements, nothing seemed to stick. The melatonin worked occasionally but left a groggy, heavy feeling the next morning. Prescription options felt extreme. He kept searching.

After deep research, he discovered that studies show up to 68% of adults are deficient in magnesium — and that this deficiency is directly linked to poor sleep quality, increased stress response, muscle tension, and low energy. More importantly, he discovered that most magnesium supplements on the market use cheap magnesium oxide, which has only about 4% bioavailability. The body barely absorbs it.

Magnesium Glycinate was different. Binding magnesium to the amino acid glycine dramatically increases bioavailability and eliminates the laxative effect that gives other forms their bad reputation. Within two weeks of switching, the difference was undeniable — deeper sleep, calmer mornings, faster muscle recovery.

SELERA was created to make high-quality, genuinely bioavailable Magnesium Glycinate accessible and affordable. We work exclusively with suppliers who test every batch — not just for potency, but for heavy metals and harmful compounds, verified by independent laboratories in the UK, Europe and the US.

Today SELERA helps over 50,000 people sleep better, recover faster, and feel calmer. Our promise is simple: pure, tested, effective. No fillers. No gimmicks. No proprietary blends. And if it doesn't work for you, we refund you in full — no questions asked.
