    Both my husband and I have taken your supplements for many years and the last 3 years Dr. Terry has given us a “more healthy than all the years we have been coming to the clinic” (15+ years).
    I think that speaks for itself! I will keep ordering those supplements forever!
    I think taking them for so long has balanced our systems so well that Dr. Terry has been able to make that determination.
    Thank you offering the product!

    My physician requires me to take a multi-vitamin with no iron or potassium. Cooper Complete met all the nutritional guidelines my physician set; without iron or potassium. It was the only one that I found that met those characteristics.

    I have taken this for a number of years and depend on it for my daily vitamin !!

  13. verified purchase

    We’ve taken Cooper Complete for years. I don’t even look for alternatives because there is a level of trust that they are superior to other vitamins.

  14. Has been an asset to my lifestyle..

  15. verified purchase

    I have been taking Cooper Complete since it became available. It has the main things I need in a daily multivitamin, and I feel Dr. Cooper knew what he was doing to come out with it.
    Thanks, Dr. Cooper!

  16. verified purchase

    My doctor recommends the Cooper brand, and I have faith that it is a quality product. I appreciate that it is “physician formulated and scientifically founded.” I don’t know whether this contributes to the good results of my annual bloodwork and to the fact that I don’t seem to get sick, but I’d think that it has to have some effect!

  17. verified purchase

    These vitamins actually dissolve into your system. I can tell a difference in my energy level when I take compared to when I miss doses.

  18. All the Cooper products are of the highest quality.

  19. verified purchase

    When I was younger I took the Stresstabs brand of vitamin, then a once-per-day national brand. I stopped taking vitamins on a regular basis but decided that as I aged I needed to pay attention to the daily requirements my body needs. I’ve been taking the Cooper Complete Basic One Iron-Free (switched from the Original Multivitamin) and am very happy. My annual bloodwork is always good, I rarely get sick, and my doctor is happy as well. So easy to take one vitamin each day (along with Omega 3) as a routine and know that I am doing something good for my body. I live in Dallas and know/trust the Cooper products, but wherever I live I will always take my Cooper regimen with me!

  20. All the Cooper products are of the highest quality.

  21. verified purchase

    I buy this for my mother and she loves it. So glad it is Iron Free. Thanks.

  22. Been taking this for over 10 years and have never had a cold. Naturopathic doctors have been impressed with what’s in them too.

  23. verified purchase

    I routinely research before ordering supplements of any kind. Cooper products, especially Basic One, always measure up to the best and most thorough lab-tested evidence regarding essential ingredients included, and an appropriate unit measurement of each. A lot of multi-vitamins I review tout mega doses (or secondary ingredients that carry no health benefit) when in fact, more is not necessarily healthy. Basic One has just the right blend of vitamins and minerals. I’ve taken Cooper Basic One for years. Despite numerous health studies during all those years, Basic One has always stood up to every test and new recommendations. Plus, living in the DFW area, I implicitly trust the Cooper Health Organization!

  24. These multi vitamins (Basic One) are recommended by my doctor.

  25. Prompt service, good Product. The only multi-vitamin that does not upset my stomach.

    My husband and I switched from the Original Multi-Vitamin to the Basic quite some time ago. I like the ingredients included in the Basic. We are happy with the Basic.

  35. Great product! Great service! Thank you!

    I have taken these a long time. Glad for no iron or Vitamin K in them since I am on Coumadin. Because of many health problems, I do not see a lot of improvement. Wish that I did.

  37. verified purchase

    I just started taking the Cooper Complete Basic One Iron Free two months ago. I decided to give it a try based on Dr. Cooper’s great reputation. I knew the product would be high quality and based on the latest scientific research. I especially liked that the supplement contained superb levels of vitamins D3 and B12. I love the small size and vanilla flavor which makes it easy to swallow for a tablet.

  38. verified purchase

    I have taken the Basic One for many years and trust the product and the health benefits. As I have gotten older the pills are becoming more difficult to swallow. I wish the coating could be changed to make it easier to swallow or offer a chewable option. Thank you for all the great products and the health information you provide.

  39. verified purchase

    I have been taking this for many years and can see the difference it makes in my hair and nails. I used to have brittle nails and very slow growing hair plus hair loss due to an autoimmune disease. Now my nails are almost as strong as the acrylics I used to pay a small fortune for and my hair loss has greatly diminished. To me, these are signs of improved health.

  40. Basic One Iron Free has the amounts I like.

  41. verified purchase

    I have been taking these for years after seeing them recommended in the book-Eat, Drink, and Be Healthy. They definitely increase my energy levels and focus. I can tell a difference in how I feel when I run out. They are the most complete men’s multivitamin I have ever found and I think they are reasonably priced for the benefits.

  42. Great product and service. High-quality products that I feel can be trusted in an industry that is not carefully watched.

  43. verified purchase

    Although I don’t sense a profound health improvement while taking these, I do “miss them” when I forget to take them, that must mean something. They do not upset my system and I trust Cooper to make quality products.

    I would have bought this as it does not have vitamin K, which promotes blood clotting, but it contains 500% of the daily for B-6, which causes blood clotting. Bummer.

    • Hi Reed,
      Our physicians specifically formulated Basic One so that individuals on Warfarin or Coumadin have a comprehensive and safe multivitamin to take. We have not seen the research indicating B-6 increases blood clot risk, and would greatly appreciate you contacting us with your references. Our phone number is 888-393-2221 and email is We look forward to your feedback.

    This is a must have for anyone over the age of 40. There are so many key ingredients that you simply can’t get from just your diet alone. It helps my entire family to stay in tip-top shape and not to mention now I can use my treadmill every day without any joint pain!

  52. verified purchase

    I take Cooper Complete supplements because I trust Dr. Cooper. Before Cooper Complete, I never knew which vitamins to take. I can work out at a higher level than I ever thought possible and I hardly ever get sick.

  53. verified purchase

    Cooper Complete helps anyone involved in the marathon we all run. It’s called life. Cooper Complete multivitamins have played an integral role in both my personal training and my sports medicine practice. I believe that Cooper Complete Original multivitamins and Cooper Complete Basic One can enhance the health of non-athletes as well.

Frequently Asked Questions

How is Basic One Iron Free different from Basic One With Iron?

Basic One Iron Free and Basic One With Iron are identical formulations with the exception of iron. Research shows most adults do not need more iron than what is consumed in food.

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

Because Basic One contains the fat-soluble vitamins A, D, and E, it is important to take this multivitamin and mineral formulation with a meal that contains fat so these vitamins will be absorbed.

Will the B vitamins in Basic One keep me awake?

While the level of B vitamins in Basic One should not disrupt sleep we suggest this multivitamin and mineral supplement be taken with breakfast or lunch if this is 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 made changes to nutrition (food) and supplement facts panels to make it easier to understand, and the International Unit (IU) measure is going away. 50 mcg vitamin D is the same amount of vitamin D as 2,000 IU. To convert from IU of vitamin D to mcg of vitamin D, multiply by 0.025.

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

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

The FDA made changes to nutrition (food) and supplement facts panels to make them 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 5-MTHF.)

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

D-alpha-tocopheryl succinate vitamin E is a natural (non-synthetic) form of vitamin E. Studies have shown that natural vitamin E is not only better absorbed but also 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 made changes to nutrition (food) and supplement facts panels to make it easier to understand, and the International Unit (IU) measure is going away. 134 mg vitamin E d-alpha-tocopheryl is equal to 134 mg. To convert from IU of vitamin E to mcg of vitamin E, multiply by 0.67.

What is folic acid as Metafolin®, L-5-MTHF?

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.

Why isn’t calcium in the Basic One Multivitamin?

Cooper Clinic physicians encourage patients to consume calcium through food rather than through supplementation.

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

Yes. It is safe to crush or cut the tablets into a smaller size.

Can I take this product if I am also taking Coumadin or Warfarin?

Vitamin K is known to impact blood clotting and is not included in Basic One Iron Free. 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 exam. Basic One has been found to lower C-Reactive Protein by 13 percent†.
