Description

MAG-8 Magnesium Complex is Double Wood's most comprehensive magnesium product, combining eight distinct forms, Citrate, Bisglycinate, Taurate, Oxide, Malate, L-Aspartate, Orotate, and Ascorbate, formulated to deliver 426mg of elemental magnesium per serving, approximately 100% of the recommended daily value for adult males. Each form is included for a different formulation reason: Bisglycinate and L-Aspartate are commonly used for tolerability and nervous system support, Taurate is studied in relation to cardiovascular wellness, Malate for its role in energy metabolism, Citrate for broad mineral replenishment, and Orotate is a less common form included for formulation diversity.*

Rather than relying on a single form, MAG-8 was formulated to provide comprehensive mineral support across multiple forms simultaneously. Every batch tested. Third-party tests by ISO/IEC 17025 accredited labs. COAs published openly. The product is Soy-Free, Gluten-Free, and Non-GMO.

The Science Behind Magnesium Complex (MAG-8 Blend) — 2,300 mg per serving (Magnesium Citrate, Bisglycinate, Taurate, Oxide, Malate, L-Aspartate, Orotate, Ascorbate)

Magnesium and Muscle Function

Magnesium plays a direct role in muscle contraction and relaxation by regulating calcium ion transport across cell membranes. When intracellular magnesium is insufficient, muscles may have difficulty completing the full relaxation phase following contraction. A 2015 review published in Nutrients (Gröber, Schmidt, and Kisters) affirmed magnesium's foundational role in neuromuscular function, noting that even subclinical insufficiency may affect muscle health over time.*

Magnesium and Relaxation Support

Several forms of magnesium have been studied for their role in supporting the nervous system's calming pathways. Magnesium is involved in normal nervous system function.*

Benefits

Magnesium Complex (MAG-8 Blend) — 2,300 mg per serving (Magnesium Citrate, Bisglycinate, Taurate, Oxide, Malate, L-Aspartate, Orotate, Ascorbate)

Magnesium is an essential mineral involved in over 300 enzymatic processes in the body, including muscle contraction and relaxation, nerve signal transmission, protein synthesis, and energy production via ATP.

The eight forms in MAG-8 were selected because each form pairs magnesium with a different co-factor, glycine, taurine, malate, citrate, aspartate, orotate, ascorbate, and oxide, reflecting different formulation reasons such as solubility, tolerability, and elemental yield. Bisglycinate and L-Aspartate are commonly used for tolerability and nervous system support. Taurate has been studied in relation to cardiovascular wellness. Malate is associated with cellular energy pathways. Together, they provide a broad mineral foundation.*

Frequently Asked Questions

What is a magnesium complex supplement, and why use multiple forms?

A magnesium complex combines multiple forms of magnesium, each with a different co-factor, to provide more comprehensive mineral support than a single form can offer. Double Wood's MAG-8 uses eight forms: Citrate, Bisglycinate, Taurate, Oxide, Malate, L-Aspartate, Orotate, and Ascorbate. Different forms are commonly used in supplements for different formulation reasons, which is why breadth of coverage matters for those building a well-rounded mineral foundation.*

What is magnesium complex good for?

Magnesium complex supports normal muscle function and relaxation, nervous system health, energy metabolism, and daily mineral replenishment. MAG-8 is particularly well-suited for those who want comprehensive magnesium coverage across multiple biological roles, from muscle and nerve function to energy production and cardiovascular wellness, without taking multiple separate magnesium products.*

When is the best time to take magnesium complex?

MAG-8 can be taken any time of day with or without food. Many people in intentional wellness routines prefer evening use because several of the forms included, particularly Bisglycinate and Taurate, support relaxation and calm, making MAG-8 a natural fit for a consistent wind-down routine. Those who experience mild digestive sensitivity are encouraged to take it with a meal.*

Is magnesium complex safe to take daily?

MAG-8 is formulated for daily use at the recommended serving of three capsules, which delivers 426mg of elemental magnesium, approximately 100% of the daily value for adult males. It is Soy-Free, Gluten-Free, and Non-GMO, and every batch tested. Those with kidney concerns or who take medications that affect mineral or electrolyte levels should consult a healthcare provider before beginning use.*

What pairs well with a magnesium complex supplement?

MAG-8 pairs naturally with L-Theanine as part of an intentional evening routine. Magnesium supports normal muscle function and nervous system relaxation, while L-Theanine supports mental calm and a composed end-of-day mindset. Together, they address both the muscular and mental dimensions of healthy unwinding, offering a more complete evening wellness pairing.*

How is Double Wood's MAG-8 different from a standard magnesium supplement?

Most magnesium supplements use one, two, or occasionally three forms of magnesium. MAG-8 uses eight distinct forms in a single serving, each with a different co-factor. It also delivers approximately 100% of the daily value of elemental magnesium (426mg) per serving. Every batch tested. Third-party tests by ISO/IEC 17025 accredited labs. COAs published openly. This combination of breadth, dosing precision, and transparency is central to how MAG-8 is formulated.*

Are there any side effects of taking magnesium complex?

MAG-8 is generally well-tolerated. Some individuals, particularly those new to higher-dose magnesium supplementation or with existing digestive sensitivity, may experience loose stools or mild digestive discomfort. Starting with one or two capsules and gradually increasing to the full serving can help minimize adjustment. Those with impaired kidney function or who are taking medications that affect electrolyte levels should consult a healthcare provider before use. As always, consult your provider if you have questions about suitability for your individual health profile.*
