We've tested our gummies up to 115°F in shade conditions without melting. However, if gummies are exposed to extreme heat for extended periods, some clumping may occur.

We suggest storing gummies in the refrigerator during hotter months to maintain optimal texture and quality.

The natural flavor in our Magtein gummies includes black cherry and a proprietary blend of natural, FDA/FEMA GRAS substances for a pleasant taste.

Our gummies have a very light sprinkle of sugar to help prevent sticking.

Magtein® is the patented, trademarked name for magnesium L-threonate, which is a mineral salt of magnesium and a brain-bioavailable form of magnesium.

Magtein® has been studied for cognitive health and mood support, with additional clinical data for sleep and occasional anxiety/stress support.

Improves Learning & Memory: Magtein® has been shown to significantly increase magnesium concentrations in the brain, improving learning capacity, short- and long-term memory, working memory, and synaptic connections in individuals of all ages.*

Improves Cognitive Ability: Magtein® demonstrated significant improvements across four major brain domains. It was shown to reduce the effects of the aging brain by nine years.*

Improves Attention & Mood: Research suggests Magtein® may help with coping with stressful events and with emotional responses to fear and anxiety.*

Most magnesium compounds on the market have low bioavailability in brain tissue because they cannot readily cross the blood-brain barrier. Magtein® is better absorbed than other magnesium compounds and has clinical research showing it is highly effective in crossing the blood-brain barrier, unlike other magnesium forms.

Key differences:

• Superior brain bioavailability through blood-brain barrier crossing
• Well tolerated by the GI tract (unlike other forms that can cause stomach upset and diarrhea)
• Effective at lower doses due to better absorption
• Clinical studies show it increases the number and density of synapses in the brain, correlating with improved cognition

Magtein® is well-tolerated. In multiple clinical trials, no significant adverse effects were reported. Magtein® is better absorbed in the GI tract and effective at lower doses than other oral magnesium products, reducing the chance of GI events (upset stomach, cramping, and diarrhea).

However, as individual responses to supplementation may vary, always consult your physician before starting any dietary supplement. Keep out of reach of children. Consult a physician if pregnant or nursing. Do not use if the safety seal is damaged or missing. Store in a cool, dry place.

In clinical trials, participants reported results after 6-8 weeks of consistent daily use. Effects of Magtein® vary; however, users have reported greater recall, improved focus, better judgment, reduced "after lunch sleepiness," feeling more relaxed, more energy and control, and a better mood when taken as part of a daily supplement regimen.

Since each person is unique, responses to supplementation can vary. Magtein® works best when taken as part of a daily supplement regimen.

The recommended dosage varies by product formulation. Generally, it is recommended to divide daily dosing into two doses (morning and evening). Clinical trials are typically conducted with divided doses, which allows flexibility based on your preferences, lifestyle, individual health, and circumstances.

It is recommended to consume Magtein® within 30 minutes of eating a meal and with a full glass of water.

Dietary supplements are recommended for adult use. As with any dietary supplement, consult with your physician before use, especially for children.

Yes, Magtein® is the patented, trademarked name for magnesium L-threonate. When you see "Magtein®" on a product, you're getting authentic, clinically studied magnesium L-threonate.

MagteinPRO is a patented formula comprised of two ingredients: Magtein® (magnesium L-threonate) and ATA Mg® (magnesium acetyl taurinate), specifically designed for enhanced neurological support. This dual-magnesium formula delivers comprehensive cognitive benefits beyond what Magtein® alone provides.

All raw materials are inspected and tested for quality and purity upon arrival at the warehouse, prior to blending and manufacturing. Magtein® is manufactured in a GMP facility that is routinely audited by third parties (NSF and FDA). Once the capsules are manufactured and bottled, they are tested for quality and purity before being released for sale.

Magtein® is not certified vegan or non-GMO by a third party; however, no GMO or animal products are used in its manufacture or contained in the product.

Yes, Magtein® is FDA GRAS (Generally Recognized As Safe).

Yes, Magtein® is both Kosher and Halal certified.

There is extensive published literature on magnesium L-threonate. See the nih.gov PubMed database for a complete list of research studies and clinical trials.
