Liposomal Magtein® Magnesium L-Threonate

100% Money Back Guarantee

  • Product Description

    Magtein is magnesium L-threonate, a form of magnesium developed by MIT researchers to raise magnesium levels in the brain. In a study of adults with sleep complaints, a daily gram of magnesium L-threonate improved sleep quality and daytime energy and focus.¹ ²


    This one is made by Quicksilver Scientific. We only carry a few products we don't make ourselves, and we chose this one because it pairs a full 1,000 mg of Magtein with 450 mg of phosphatidylcholine in a liposomal liquid.


    May support:

    • Restful, high-quality sleep

    • Memory and focus

    • A calm, steady mood


    Ingredients: Per serving (15 mL): 1,000 mg magnesium L-threonate as Magtein (72 mg elemental magnesium) and 450 mg phosphatidylcholine, in a liposomal liquid with natural citrus oils. See the label photo for the complete ingredient list.


    If you are pregnant or breastfeeding, please check with your healthcare professional before using this one (here's why). The same goes if you have a health condition or take medication.


    These statements have not been evaluated by the FDA. This product is not intended to diagnose, treat, cure, or prevent any disease.

  • How to Use

    One serving is 15 mL a day, split in two: 5 mL (1 teaspoon) during the day and 10 mL (2 teaspoons) about an hour before bed. Each bottle holds 30 servings.

    It's best taken on an empty stomach.


    Keep the bottle in the fridge after opening.

THE MAGNESIUM MADE FOR YOUR BRAIN

Magnesium is involved in hundreds of processes in the body, but most forms do little to raise levels in the brain. Researchers at MIT developed magnesium L-threonate for exactly that, and in their studies it raised brain magnesium and improved learning and memory.¹


In a 21-day study of adults with sleep complaints, 1 gram a day of magnesium L-threonate, the same amount in one serving of this formula, improved deep sleep and REM sleep scores along with daytime energy, mood and alertness.²


WHY WE CARRY IT

Almost everything on our shelves is made by us. When we do carry another company's product, it's because it fills a spot in your routine that we think matters and we trust how it's made. Quicksilver Scientific is a Colorado company known for its work with liposomal delivery.


We use this one on busy days when our minds won't slow down. A teaspoon during the day and two before bed is an easy routine, and the liposomal liquid is gentle on the stomach.

Frequently Asked Questions

  • Q: How much should I take?

    15 mL a day: 5 mL (1 teaspoon) during the day and 10 mL (2 teaspoons) about an hour before bed. Each bottle holds 30 servings.

  • Q: How is Magtein different from other magnesium?

    Magtein is magnesium L-threonate, a form developed to raise magnesium levels in the brain, which most forms of magnesium don't do well.

  • Q: Why split it into two doses?

    The daytime dose is the smaller one, and the larger dose goes in the hour before bed. That's how Quicksilver suggests splitting it.

  • Q: Can I take it with other magnesium?

    Many people do. If you take a lot of magnesium from several sources, check the totals with your healthcare professional.

  • Q: What does "liposomal" mean?

    Liposomes are microscopic bubbles made from phospholipids, the same kind of material your cell membranes are made of. They wrap around the nutrient to help it get absorbed.

  • Q: Who should check with a doctor first?

    If you are pregnant or breastfeeding (here's why), have a health condition or take medication, check with your healthcare professional before use.

  • Q: Why should I refrigerate it?

    Cold keeps the liposomes stable once the bottle is open, so keep it in the fridge after opening.

  • Q: Is this an Addictive Wellness product?

    No. It's made by Quicksilver Scientific. We carry a small number of their products that we think are a great fit alongside ours.
