Mental-Mag™ · Magnesium for the Mind

A mind that won’t slow down? This is the calm your brain has been missing.

When the overthinking won’t quit, most magnesium either does nothing or leaves you foggy. Mental-Mag does neither. One patented form builds focus; one calms the over-excitation that keeps you wired. Quiet mind, clear head — not dulled.

  • The Builder — Magtein® L-Threonate (1,000 mg). The form developed from MIT research, clinically shown to cross the blood-brain barrier and raise brain magnesium — at the full clinical dose, not the under-dose most brands ship.

  • The Balancer — ATA Mg® Acetyl-Taurinate (450 mg). A second patented form that crosses through a different pathway and calms neural over-excitation — so your brain settles down without being shut down.

  • One simple system, three capsules a day. Replaces the day/night magnesium juggling act. No powders, no stack to manage.

Hear from our experts

“Black seed oil only works if what’s actually in the bottle is real. The compound everyone has read about is thymoquinone — so we cold-press the Nigella sativa to help protect it, and we standardize for it, so every softgel is consistent bottle to bottle. Then we put it in a softgel, because the single biggest reason people quit black seed oil isn’t the oil — it’s the taste. Potent enough to matter, easy enough to actually keep taking.”

Frequently Asked Questions

What is thymoquinone, and why standardize for it?

Thymoquinone (TQ) is the key compound in black seed oil — the one most of the research and reviews point to. Standardizing for it means every softgel is consistent bottle to bottle, so you know what you're getting instead of a mystery oil.

How is this different from the liquid?

It's the same cold-pressed Nigella sativa — just in a softgel. No taste, no burn, no spoon, and pre-measured at 1 a day. The format removes the single biggest reason people quit black seed oil.

How long until I notice anything?

Black seed oil is a daily-ritual supplement, so consistency matters most. Give it time as part of a steady routine rather than expecting an overnight change. Everyone is different.

Can I take it with my medications?

If you take medication, are pregnant or nursing, or have a medical condition, talk to your healthcare provider before starting. It's a simple question worth asking, and the right place to start.

How many do I take?

One softgel daily with a meal — 60 softgels is a 60-serving bottle. No measuring, no dropper, no aftertaste.

Is it tested?

Yes — it's third-party tested for purity and standardized to 5% thymoquinone, with a clean label and no unnecessary fillers. A Certificate of Analysis is available on request.

Why a softgel instead of the oil or a capsule?

The softgel protects the cold-pressed oil, doses it precisely, and — most importantly — has no taste or burn. It's the form people actually keep taking.

How should I store it, and what if the color varies?

Store at room temperature, out of direct sunlight. As a natural, cold-pressed oil, slight color variation between batches is normal and not a quality issue.
