2. What types of magnesium are included in Opti-5 Magnesium?

3. Is magnesium without oxide better for absorption and digestion?
Magnesium oxide has lower bioavailability (absorption rate in the body) than many other forms of magnesium. Research indicates that other forms including magnesium citrate, magnesium lactate, and magnesium chloride offer better levels of absorption.
Magnesium oxide is an osmotic laxative, an effect related to its poor absorbability. It draws water into the intestines, which can cause digestive discomfort. Because of this, magnesium forms with higher bioavailability, like magnesium glycinate and chelated magnesium, may be a better choice to limit digestive concerns.
4. How much magnesium should I take daily?
The recommended daily intake of magnesium ranges from 310 to 420 mg for adults. This can vary based on age, sex, and life stage; for example, magnesium requirements are higher for adolescents and people with high physical activity levels.
5. Can magnesium help with occasional stress, relaxation, and muscle health?
There are many forms of magnesium, each one with unique effects on processes throughout the body. All forms of magnesium have been shown to support occasional stress, relaxation, and muscle health.*
