Frequently Asked Questions (Q&A)
What is this product?
NOW Foods Magtein is a US original import supplement featuring Magtein®, a patented form of magnesium (Magnesium L-Threonate). While magnesium is best known for its role in bone and nervous system function, research shows it is also critical for normal brain health and cognitive function — yet most forms of magnesium are not easily absorbed into the nervous system. Magtein® was developed to readily cross into the brain. The bottle contains 90 vegetarian capsules.
What are the key ingredients and their benefits?
Each 3-capsule serving provides 2,000mg of Magtein® Magnesium L-Threonate, delivering 144mg of elemental magnesium. The formula supports memory and learning and promotes brain health. Vegetarian/vegan capsules, made without wheat, gluten, soy, milk, egg, fish, shellfish, tree nut or sesame ingredients.
Who is this product suitable for?
Suitable for adults who want to support normal brain health and cognitive function, students and professionals with mentally demanding routines, and anyone whose diet may not provide enough magnesium.
How should I take it?
Take 3 capsules daily in divided doses — 1 capsule in the morning and 2 capsules two hours before sleep.
Are there any cautions or ingredient notes?
For adults only. Like other magnesium products, Magtein® may induce sleepiness, drowsiness or headaches at first — reduce the dosage, consult a doctor, or discontinue use if these conditions persist. Consult your physician if pregnant or nursing, taking medication, or have a medical condition. Keep out of reach of children.
How should I store it?
Store in a cool, dry place after opening. Do not eat the freshness packet — keep it in the bottle to help maintain quality.
