Nature NatureMin

Bone, teeth and skeletal health
The calcium, phosphorus, magnesium content helps maintain bone density, strength of teeth, and proper skeleton structure. 

Muscle function and cramps
Minerals like magnesium play a role in muscle contraction/relaxation and may help reduce cramping. Calcium and magnesium both are involved in normal muscle work.

Electrolyte / fluid balance
Helps regulate fluid and ionic balance in the body since some minerals are needed to regulate osmotic pressure and fluid between cells. 

Thyroid and metabolic function
Because of iodine and selenium, components in Nature-Min support normal thyroid function, which is important for metabolism, energy levels, and hormonal balance.

Immune system support
Some of the trace elements (e.g. zinc, selenium, copper) help with immune defense, protecting cells from oxidative stress, helping in healing, etc. 

Preventing mineral deficiencies
As soils and diets in many places are deficient in certain minerals, a supplement helps fill nutritional gaps.
