With 13 different bioavailable forms of magnesium, including glycinate and L-threonate, this formula targets cognitive function, mood balance, muscle recovery, and metabolism. It is particularly beneficial for those who experience stress, poor sleep, or muscle tension, as well as athletes and active individuals looking to maintain optimal magnesium levels.

The standout feature of this product is its advanced liposomal delivery system, which uses sunflower phosphatidylserine to enhance nutrient absorption. This technology ensures that the magnesium is transported effectively into the cells, maximizing its benefits. Users can expect improved relaxation, better sleep quality, and a sense of calm, especially when taken consistently as directed.

In terms of design, the supplement comes in a blue bottle containing 90 capsules, providing a 30-day supply.

The product is vegan, gluten-free, soy-free, non-GMO, and free from artificial fillers, making it suitable for a variety of dietary preferences. It is manufactured in a GMP-compliant facility and third-party tested for purity and potency, ensuring quality and safety.

However, some users may find the capsule size relatively large, which could be a challenge for those who have difficulty swallowing pills. Additionally, the 30-day supply per bottle might require frequent repurchasing, which could be a consideration for long-term use. As of now, there are no customer reviews available, so real-world experiences are yet to be seen, but the ingredient profile and brand reputation suggest a high-quality product.

Overall, the Plus+Ultra Magnesium Complex offers a well-rounded, highly absorbable magnesium supplement that addresses multiple health needs. Its unique blend of 13 forms and liposomal technology sets it apart from standard magnesium products. While the capsule size and supply duration may be minor drawbacks, the potential benefits for relaxation, sleep, and overall vitality make it a worthwhile addition to a daily wellness regimen.
