Ingredients explained
Magnesium (from oxide, glycinate, taurate, citrate, and Aquamin seaweed minerals)
Magnesium participates in hundreds of enzymatic reactions, helping regulate muscle and nerve signaling, energy production, and the balance of calcium in bones and soft tissues.
Caution: High intakes may cause loose stools, especially from magnesium oxide; take with food and split doses to improve tolerance.
Calcium (from Aquamin seaweed minerals and calcium citrate)
Calcium provides the mineral building blocks for bones and teeth and supports muscle contraction and nerve transmission.
Caution: Space away from certain minerals and some medications because calcium can reduce their absorption.
Vitamin D3 (cholecalciferol)
Vitamin D3 enhances intestinal absorption of calcium and magnesium and supports normal mineral balance for bone structure.
Caution: Avoid combining with high-dose vitamin D from other supplements to prevent excessive intake.
Zinc (from L-OptiZinc monomethionine)
Zinc serves as a cofactor for enzymes involved in bone remodeling and cellular function, and the monomethionine form is designed for efficient absorption.
Caution: Take with food to reduce stomach upset, and separate from high-calcium doses to avoid competition for absorption.
How they work together
Magnesium and calcium supply complementary minerals for muscle and bone needs, with magnesium helping regulate calcium movement into tissues. Vitamin D3 supports intestinal uptake of both minerals, while zinc contributes to normal bone remodeling processes.
Safety and tips
Label Warning: For adults only. Consult a physician if you are pregnant or nursing, taking medication, or have a medical condition. Natural color variation may occur.
Who should be cautious: People with kidney concerns, a history of kidney stones, or who are on thyroid medications or certain antibiotics may need to separate dosing due to possible absorption issues with calcium and magnesium. Those on anticoagulants may need to consider vitamin K content if present in other products taken concurrently. If you use medications that may interact with calcium or magnesium, discuss with a healthcare provider before use.
Storage: Store in a cool, dry place after opening.
