CogniMag* - Your favorite is back, improved

CogniMag* from EssentialSeries is a dietary supplement based on magnesium and pantothenic acid.

In the improved formula of CogniMag, we combined two next-generation forms of magnesium (Magtein® and ATA Mg®) along with vitamin B5, with a clear focus: day-to-day cognitive performance. We bring together the prestige of Magtein® with ATA Mg®, backed by pantothenic acid (which contributes to normal intellectual performance), for a complete formula.

The improved CogniMag* formula keeps all the good stuff from the original, with a renewed and optimized composition.

Why is CogniMag* back and what’s changed?

Because it’s a well-known classic in our catalog that’s been a big hit: many of you asked for its return. We worked hard to bring you an improved version, with an ingredient setup that leverages the value of two leading patents on the market: Magtein® and ATA Mg®. The goal is clear: to deliver a top-quality magnesium-based formula for cognitive support. This goes from selecting raw materials to the final product, crafted by HSN’s specialists.

If you’re looking for other high-purity magnesium options with excellent tolerance, but less focused on cognitive properties specifically, you can find plenty of alternatives in HSN by checking out our category: Magnesium.

Next-generation magnesium: Magtein® + ATA Mg®

Magtein® is the registered trademark of ThreoTech LLC for magnesium L-threonate, a patent widely recognized among the most demanding users of this mineral, as it’s considered a high-tech, highly nutritional form of magnesium threonate. ATA Mg® (raw material from Synapharm SA) provides magnesium acetyl taurate, an alternative mineral salt, excellent for maximizing CogniMag’s properties.

The combo of both sources isn’t random: we aim for balanced action profiles with both mineral salts, along with the support of vitamin B5, which boosts the product’s overall effect

Pantothenic acid (Vitamin B5)

  •  Contributes to normal intellectual performance.
  •  Helps to reduce tiredness and fatigue.
  •  Contributes to normal energy metabolism.
  •  Contributes to the normal synthesis and metabolism of steroid hormones, vitamin D, and some neurotransmitters.

Magnesium

  •  Contributes to the normal functioning of the nervous system.
  •  Contributes to normal psychological function.
  •  Helps to reduce tiredness and fatigue.

Why buy CogniMag* from HSN?

Patent value: more than just a logo

The chosen raw materials matter, and they’re not just a marketing tool.

Magtein® and ATA Mg® guarantee traceability, standardized quality, and consistency of the ingredients used. We picked these forms for their technological profile and how they fit our goal: a product aimed at top-quality cognitive support, backed by the technological development of its ingredients, in a perfectly dosed and optimized formula by the HSN development team.

High concentration with easy use

Each daily dose of 2 vegetable capsules delivers what you’d expect from the quality standard of an HSN formula: magnesium L-threonate and magnesium acetyl taurate in significant amounts, whose combination provides 128,9 mg of elemental magnesium. We designed it so you can effortlessly integrate it into your routine, since just one daily serving lets you forget about it.

Why this selection of magnesium salt forms?

At HSN, we care about every detail, and CogniMag isn’t “Cogni” for nothing. The choice of magnesium forms affects its bioavailability, tolerance, and ultimately how it works in the body. With CogniMag, we bet on the duo Magtein® + ATA Mg®, a selection that raises the bar compared to magnesium formulas without Threonate or Acetyl Taurinate.

In CogniMag* we select top international raw materials to support intellectual performance and cognitive support.

Suitable for vegan diets

It’s a 100% vegan formula in vegetable capsules. No animal-derived ingredients.

What to combine the product with?

Depending on your goal, you can pair it with other compounds like caffeine, different forms of choline, or L-carnitine.

Quality and transparency – The HSN seal

At HSN we work with a “clean label” approach. That means our formulas, including CogniMag, contain no unnecessary ingredients, are allergen-free, and GMO-free, all with clear labeling. Manufactured following the highest industry quality standards. Our commitment is to offer you premium quality supplements at a fair price.

Frequently asked questions (FAQ)

Why combine two forms of magnesium?

Because we want to complement nutritional action profiles: we combine the base features of L-threonate with the alternative approach of acetyl taurate. The result is a balanced and complete formula, designed for cognitive support with everyday use.

What role does vitamin B5 play?

It’s the perfect support: vitamin B5 contributes to normal intellectual performance. In a formula designed for studying, working, or staying focused, it makes total sense.

How “strong” is the magnesium dose?

We prioritized quality of the forms used and a significant but not excessive amount. The daily dose reaches 128,9 mg of elemental magnesium, a comfortable amount for maintaining daily intake, with the option to use products that provide complementary magnesium, like multivitamins or electrolyte-based formulas.

It's a bit cheap, but it works. I gave it to my son to help him prepare for exams, and watching him from the sidelines, it seemed to me that it had a noticeable effect on his brain function.

Carillo pero es efectivo. lo he dado a mi hijo para preparar examenes y observando desde fuera, ma ha parecido que tuviera efecto modulador cerebral nortable.

A bit expensive

A bit expensive to maintain indefinitely at two capsules a day, but certainly compared to other brands it is well priced.

Un poco caro de mantener indefinidamente a dos capsulas al día, pero seguramente en comparación con otras marcas está bien de precio.
