CHF #4 Vitamin E bottle with the Country Health logo

Vitamin E is the body’s classic fat-soluble antioxidant vitamin, and Country Health pairs it with a few supporting micronutrients. This article walks through each ingredient in CHF #4 Vitamin E 100 Capsules and what research has found about it.

Full ingredient list (per serving): Vitamin E (as d-alpha-tocopheryl succinate) 120 mg (800% DV); Riboflavin (as R-5-P) 900 mcg (69% DV); Magnesium (as chelate) 5.8 mg (1% DV); Selenium (as selenomethionine) 2.5 mcg (5% DV); and Chromium (as chelate) 50 mcg (143% DV). Other ingredients: magnesium stearate, microcrystalline cellulose, silica, and a gelatin capsule. The label suggests one capsule daily or as directed.

What does vitamin E do as an antioxidant?

According to the NIH Office of Dietary Supplements, vitamin E is a fat-soluble antioxidant that helps stop the chain reaction of free radicals formed when fats oxidize. Alpha-tocopherol is the form that meets human requirements. ODS also notes roles in immune function and cell signaling. Nuts, seeds, and vegetable oils such as sunflower, safflower, and wheat germ oil are among the best food sources.

Adults need 15 mg of alpha-tocopherol a day. CHF #4 provides 120 mg of vitamin E as d-alpha-tocopheryl succinate—the natural stereoisomer labeled “d-alpha”—in an ester form that the body can absorb after hydrolysis. That serving is well above the RDA and still under the adult upper limit of 1,000 mg of supplemental alpha-tocopherol.

Why include selenium with vitamin E?

Selenium is an essential mineral that becomes part of selenoproteins, including glutathione peroxidases that help protect cells from oxidative damage, ODS explains. Seafood, meat, poultry, eggs, and Brazil nuts are notable food sources. The adult RDA is 55 mcg. CHF #4 includes 2.5 mcg of selenium as selenomethionine—a small complementary amount that sits naturally beside vitamin E in many antioxidant-minded formulas.

What about riboflavin (vitamin B2) and chromium?

Riboflavin is a B vitamin that helps enzymes turn food into cellular energy and supports antioxidant recycling pathways. ODS lists dairy, eggs, lean meats, and fortified grains as common sources. Adults need 1.1–1.3 mg daily. CHF #4 supplies 900 mcg (0.9 mg) as riboflavin-5-phosphate (R-5-P), an active phosphate form.

Chromium is a trace mineral that contributes to normal insulin action and carbohydrate, fat, and protein metabolism. The formula provides 50 mcg as a chelate (143% DV), plus a small 5.8 mg of chelated magnesium.

How do these ingredients work together?

CHF #4 centers on a robust natural-form vitamin E dose and surrounds it with selenium, riboflavin, chromium, and a touch of magnesium. The pattern reads like an antioxidant-forward daily capsule rather than vitamin E alone.

Who might enjoy it: adults who want a dedicated vitamin E capsule, people whose diets are light on nuts and seed oils, and anyone who prefers d-alpha-tocopheryl succinate with mineral companions in one Country Health soft-style capsule routine.

Who should check with a clinician first?

Please check with your clinician first if you:

  • Are pregnant or breastfeeding.
  • Take anticoagulant or antiplatelet medicines (ODS notes that high-dose vitamin E can affect clotting).
  • Are scheduled for surgery.
  • Already use other high-dose vitamin E products, so total intake stays appropriate for you.

Frequently asked questions

How much vitamin E is in CHF #4?

120 mg of vitamin E as d-alpha-tocopheryl succinate per serving (800% DV), plus riboflavin, selenium, magnesium, and chromium.

Is 120 mg of vitamin E a high dose?

It is above the 15 mg adult RDA and below the 1,000 mg adult upper limit for supplemental alpha-tocopherol. Follow the label and your clinician’s advice.

Should I take it with food?
