Magtein® Stress-Less

Why do these ingredients matter?

Magnesium supports normal nervous system and psychological function and helps reduce tiredness. Inositol is involved in cell membrane structure and intracellular signaling. Ashwagandha is an adaptogen studied in stress and sleep. The formula combines all three for a routine spanning the active day and evening.

What research informs Magtein® Stress-Less?

Randomized trials of magnesium L-threonate have assessed sleep quality, waking behavior, energy, alertness, and selected memory and reaction-time measures. Ashwagandha studies explore perceived stress, cortisol, and sleep. These research areas informed the morning-and-evening routine, with inositol completing the formula. Ingredient studies do not establish the same results for the finished product.

FAQ / Magtein® Stress-Less

Good questions. Clear answers.

Talk to us ↗

How does Magtein® Stress-Less differ from a standard magnesium supplement?

It combines Magtein® magnesium L-threonate with inositol and ashwagandha root extract. The formula is designed around a daily nervous system routine and an evening wind-down, rather than magnesium alone.

Why does the serving contain 116 mg of magnesium?

The serving contains 1,500 mg of Magtein® magnesium L-threonate, providing 116 mg of elemental magnesium—31% of the EU Nutrient Reference Value. It combines this specific form with inositol and ashwagandha.

Why take one capsule in the morning and two before bed?

The schedule follows the formula's day-and-evening concept. Take one capsule in the morning and two about two hours before bed. Follow this schedule and do not increase the serving on your own.

Does the product act as a sleeping pill?

No. Do not treat it as sleep medication or expect an immediate drug-like effect. It is a supplement for regular use according to the directions. If you take sedatives or sleep medication, do not use it without your doctor's approval.

What does 9 mg of withanolides mean?

Withanolides are characteristic compounds found in ashwagandha. The daily serving provides 30 mg of ashwagandha root extract, including 9 mg of withanolides. Specifying their amount gives more detail than the extract's weight alone.

How long does a bottle last, and are the capsules vegan?

Each bottle contains 90 capsules, providing 30 days at three capsules daily. The pullulan capsule shell is suitable for vegans.
