  1. My contact with Cooper Clinic spans more than 35
    years. Service has always been terrific.

  2. Excellent! Also, I like the fact that Coopers contain 2000 IU of Vitamin A, instead of the excessively large amounts contained in other multiple vitamins, which is not good, especially for women. (Note: I began taking Coopers Vitamins after watching an interview with Orville Rogers, [ref. book: The Running Man], when he stated that he takes Coopers Vitamins. )

Frequently Asked Questions

Who should take Basic One With Iron?

Women who experience blood loss from a monthly period, those on blood thinners, and older adults (who often have diets low in iron) often need supplemental iron. Basic One With Iron contains 18 mg iron and is for adults who need more iron than what is consumed in food.

What time of day should I take Basic One With Iron?

The fat-soluble vitamins A, D, and E are in Basic One so it’s important to take this multivitamin and mineral formulation with a meal that contains fat to aid absorption of these vitamins.

Will the B vitamins in Basic One keep me awake?

The B vitamins in Basic One should not negatively impact sleep. However, we suggest this multivitamin and mineral supplement be taken with breakfast or lunch if sleep issues are a concern.

I notice vitamin D is now shown as 50 mcg (microgram) rather than 2,000 IU (International Unit). Why did you make this change?

The FDA has made changes to nutrition (food) and supplements facts panels to make it easier to understand, and the International Unit (IU) measure is going away. Multiply the vitamin D in IUs by 0.025 to convert to mcg. 2,000 IU vitamin D3 is equal to 50 mcg vitamin D3.

I notice vitamin A is now shown as 600 mcg (microgram) rather than 2,000 IU (International Unit). Why did you make this change?

The FDA has made changes to nutrition (food) and supplement facts panels to be easier to understand, and the International Unit (IU) measure is going away. To convert from IU of vitamin A or beta-carotene to mcg RAE (Retinol Activity Equivalents), multiply by 0.30. 600 mcg vitamin A is equal to 2,000 IU vitamin A.

I notice folate is now shown as 333 mcg DFE (200 mcg L-5-MTHF). What does this mean?

The FDA has made changes to nutrition (food) and supplement facts panels to make it easier to understand. To convert from mcg (microgram) to Dietary Folate Equivalents (DFE), divide by 0.60. (This conversion applies to both folic acid and folate in the 5-MTHF form.)

What is folic acid as Metafolin®, L-5-MTHF and why is it used in this formulation?

Metafolin® is a brand name for a patented form of 5-methyltetrahydrofolate (5-MTHF) made by Merck. A percentage of the population has a mutation in one of the enzymes involved in the metabolism of folic acid. 5-MTHF circumvents this mutation and allows the body to be better able to get the benefits from supplementation.

What is vitamin E as d-alpha-tocopheryl succinate?

Studies have shown that natural vitamin E (d-alpha-tocopheryl) is better absorbed and better retained in the body than the synthetic form, dl-alpha tocopherol.

Why is vitamin E reflected in mg (milligram) rather than IU (International Units)?

The FDA has made changes to nutrition (food) and supplement facts panels to make it easier to understand, and the International Unit (IU) measure is going away. To convert from IU of vitamin E to mcg of vitamin E, multiply by 0.67. 134 mg vitamin E d-alpha-tocopheryl is equal to 134 mg.

Why isn’t calcium in the Basic One Multivitamin?

Cooper Clinic physicians encourage patients to consume calcium through food rather than through supplementation so none of the Cooper Complete multivitamins contain calcium. If more calcium is needed than what is consumed through food and fortified-foods, Calcium Citrate as a standalone ingredient is available.

Can I cut or crush the tablets to make them smaller?

Basic One With Iron is safe to crush or cut.

Can I take Basic One With Iron if I am also a blood thinner such as Coumadin or Warfarin?

Basic One With Iron does not contain Vitamin K, which is known to impact blood clotting. However, please talk with your doctor or INR Clinic before adding this supplement to your diet.

How does Basic One impact C-reactive protein (CRP)?

C-Reactive Protein (CRP) is a marker of inflammation found in the blood which increases when there’s inflammation in the body. Your physician may order this blood test as part of your annual preventative exam. In a research study, Basic One (Iron Free) was found to lower C-Reactive Protein by 13 percent†.

Is it true that tea can reduce iron absorption?

Yes. Because tea reduces the absorption of iron, we recommend that you wait one hour after taking Basic One With Iron before drinking hot or iced tea.
