Calcium, Magnesium, and Vitamin D: What the Research Says About the Ingredients in CHF #2 Cal Mag

By Jenn Resendiz

CHF #2 Cal Mag bottle with the Country Health logo

Calcium and magnesium are two of the body’s most familiar minerals for bones, muscles, and everyday calm. This article walks through each featured ingredient in CHF #2 Cal Mag 120 Capsules and what research has found about it.

Full ingredient list (per 2-capsule serving): Vitamin D (as cholecalciferol) 2.5 mcg (13% DV); Calcium (as citrate, chelate, ascorbate, glycinate & gluconate) 194 mg (15% DV); Vitamin C (as calcium ascorbate) 20 mg (22% DV); Magnesium (as oxide & aspartate) 190 mg (45% DV); and a proprietary blend 416 mg of betaine HCL, trace mineral blend, alfalfa leaf, dandelion root, and parsley leaf. Other ingredients: microcrystalline cellulose, magnesium stearate, and a gelatin capsule. The label suggests 2 capsules 2–3 times daily, or as directed by a qualified health professional.

Why do calcium and vitamin D work so well together?

The NIH Office of Dietary Supplements (ODS) explains that calcium makes up much of the structure of bones and teeth and also supports muscle function, nerve transmission, and blood vessel activity. Almost all of the body’s calcium is stored in the skeleton, which is constantly remodeling. Vitamin D promotes calcium absorption in the gut and helps maintain the calcium and phosphate levels needed for normal bone mineralization.

Adults generally need 1,000–1,200 mg of calcium a day depending on age and sex, and 15–20 mcg (600–800 IU) of vitamin D. Dairy foods, fortified beverages, leafy greens such as kale and broccoli, and canned fish with bones are classic calcium sources. Fatty fish, fortified milk, and sunlight help with vitamin D. Each two-capsule serving of CHF #2 provides 194 mg of calcium from several well-known forms plus 2.5 mcg of vitamin D3 (cholecalciferol).

What does magnesium add for muscles and bones?

ODS notes that magnesium is a cofactor in more than 300 enzyme systems, including pathways for muscle and nerve function, energy production, and bone structure. About half of the body’s magnesium sits in bone. Green leafy vegetables, nuts, seeds, legumes, and whole grains are rich food sources. Many people in the United States consume less magnesium than recommended.

Adult RDAs range from about 310–420 mg depending on age and sex. CHF #2 supplies 190 mg of magnesium per two-capsule serving as oxide and aspartate—forms commonly used in supplements—alongside calcium so the two minerals can support everyday muscle comfort and skeletal nutrition together.

How does a little vitamin C fit into a Cal Mag formula?

Vitamin C (as calcium ascorbate here) is best known for collagen synthesis, antioxidant activity, and immune support, according to ODS. Collagen is a major protein in connective tissue, so pairing a modest 20 mg of vitamin C with calcium and magnesium fits a “bones-and-tissues” pattern. Citrus, peppers, kiwi, and berries are familiar food sources; the ascorbate form also contributes a small amount of calcium.

What is the proprietary botanical and betaine blend for?

The 416 mg blend includes betaine HCL (a compound long used in digestive formulas), a trace mineral blend, alfalfa leaf, dandelion root, and parsley leaf. These botanicals are traditional companions in mineral formulas and add plant-based nutrients alongside the primary calcium–magnesium–vitamin D core. They are listed without individual Daily Values because they are part of a proprietary blend.

How do these ingredients work together?

CHF #2 pairs calcium with vitamin D for absorption support, adds a meaningful magnesium dose for muscle and bone biochemistry, and includes a little vitamin C plus a botanical mineral blend. The label’s split-dose suggestion (2 capsules 2–3 times daily) matches the idea that smaller, repeated calcium servings may be used comfortably through the day.

Who might enjoy it: adults looking for a daily calcium–magnesium routine, people whose diets are light on dairy or leafy greens, and anyone who prefers a Country Health formula that also includes vitamin D3 and supporting botanicals.

Who should check with a clinician first?

Please check with your clinician first if you:

  • Are pregnant or breastfeeding.
  • Have a history of kidney stones or are advised to limit calcium or vitamin D.
  • Take levothyroxine, certain antibiotics (such as quinolones or tetracyclines), bisphosphonates, or other medicines that ODS lists as possible calcium or magnesium interactions (timing doses apart may help if your clinician agrees).
  • Already use high-dose calcium, magnesium, or vitamin D products, so total intake stays appropriate for you.

Frequently asked questions

How much calcium and magnesium are in a serving?

Each two-capsule serving provides 194 mg calcium and 190 mg magnesium, plus 2.5 mcg vitamin D3 and 20 mg vitamin C.

How should I take CHF #2?

The label suggests 2 capsules 2–3 times daily, or as directed by a qualified health professional.

Why include vitamin D with calcium?

ODS explains that vitamin D is required for active calcium absorption in the gut and helps maintain calcium balance for bone mineralization.

Is the magnesium dose high?

190 mg per serving is a substantial contribution toward the adult RDA. The supplemental magnesium UL for adults is 350 mg from supplements; follow the label and your clinician’s advice.
