Momentous Magnesium L-Threonate Supplement

Magnesium L-Threonate can be taken at different times depending on your wellness goals. For sleep and relaxation, take all three capsules 30 to 60 minutes before bed. If you're using it for cognitive support, consider spreading the dose throughout the day — ideally one capsule with each meal — to promote mental clarity and focus without drowsiness.

Momentous sources its Magnesium L-Threonate from the United States. Domestic sourcing helps ensure consistent quality, purity, and adherence to rigorous manufacturing standards from raw material to final product.

The vegetable-derived cellulose used in Momentous Magnesium L-Threonate comes from plant sources and is used to form the capsule that delivers the active ingredients. While the cellulose is plant-based, it may not be corn-free. If you have a corn allergy or sensitivity, consult with your healthcare provider before use.

Rice flour is used as a natural alternative to magnesium stearate, helping improve capsule consistency and ingredient blending while keeping additive levels low. It’s hypoallergenic, supports clean-label preferences, and ensures quality without synthetic fillers.

Sleep benefits may become noticeable after a few weeks of consistent use, though individual results vary. Some people feel more rested within days, while others may need several weeks for the supplement to take full effect.

Magnesium L-Threonate is generally well-tolerated. In some cases, higher doses can cause mild digestive issues like bloating, cramping, or diarrhea. Sticking to the recommended dosage and taking it with food can help minimize discomfort.
