NTA Mineral Balance & Hydration

Question 1

Which nutrients are key cofactors for proper calcium absorption and utilization?

Accepted Answer

Vitamin D and magnesium

Answer

Vitamin D increases intestinal calcium absorption, and magnesium is required for vitamin D activation and calcium regulation. Without these cofactors, calcium may not be used properly.

Question 2

Why is adequate stomach acid (HCl) important for mineral status?

Accepted Answer

It ionizes minerals, which helps their absorption

Answer

An acidic stomach environment helps free and ionize minerals such as calcium, iron, and zinc from food, making them absorbable. Low stomach acid (hypochlorhydria) is a common driver of mineral deficiency.

Question 3

Which hormone raises blood calcium by pulling calcium from bone when levels fall?

Accepted Answer

Parathyroid hormone (PTH)

Answer

PTH is secreted when blood calcium drops. It stimulates bone resorption, renal calcium reabsorption, and vitamin D activation. Calcitonin has the opposite effect.

Question 4

A common NTA hydration guideline is to drink roughly how much water daily?

Accepted Answer

Half of body weight (in pounds) in ounces

Answer

The general guideline is half your body weight in pounds, expressed as ounces (for example, a 160 lb person drinks about 80 oz). Additional water is advised to offset dehydrating beverages.

Question 5

Which group of minerals functions primarily as electrolytes that regulate fluid balance and nerve conduction?

Accepted Answer

Sodium, potassium, chloride

Answer

Sodium, potassium, and chloride carry electrical charge in body fluids. They drive fluid distribution, nerve impulses, and muscle contraction.
