Your Foundation for Daily Wellness

A quality multivitamin serves as nutritional insurance, filling the gaps that even the healthiest diets sometimes leave behind. Basic One delivers comprehensive daily nutrition in a single, easy-to-take tablet, formulated with premium forms of essential vitamins and minerals that your body can actually use.

This iron-free formula is specifically designed for adults who don’t need supplemental iron or who need to avoid it due to certain health conditions. Many men and postmenopausal women fall into this category, as their iron needs are typically met through diet alone. For those with hemochromatosis or other conditions requiring iron restriction, an iron-free multivitamin isn’t just preferred—it’s essential.

Premium Ingredients That Make a Difference

Not all multivitamins are created equal, and the forms of nutrients matter just as much as the amounts. Basic One uses methylated folate (5-MTHF) rather than synthetic folic acid, which is particularly important for the estimated 40% of the population with MTHFR gene variations that make it difficult to convert standard folic acid into its usable form. Similarly, the vitamin B12 comes as methylcobalamin, the active form your body can use immediately without conversion.

The formula includes 2,000 IU of vitamin D3, recognizing that most Americans don’t get adequate vitamin D from sun exposure alone, especially during winter months or for those living in northern climates. You’ll also find meaningful doses of magnesium and zinc—minerals that play critical roles in hundreds of bodily functions yet are commonly deficient in modern diets.

Clean, Thoughtful Formulation

Basic One contains no biotin, which is an intentional choice. While biotin is beneficial for many, it can interfere with certain blood tests, potentially leading to inaccurate results for thyroid function and other important health markers. By excluding biotin, this formula ensures your lab work remains accurate when you need it most.

The formula is also free from artificial colors, gluten, and GMOs. Each ingredient is carefully selected and proportioned based on current nutritional science, providing levels that support optimal health without excessive mega-doses that can sometimes do more harm than good.

Simple, Effective Daily Support

Taking just one tablet daily with food provides comprehensive nutritional support for your immune system, energy production, bone health, cardiovascular function, and overall wellness. Each bottle contains 60 tablets, providing a two-month supply when taken as directed.

This product is gluten-free, non-GMO, and undergoes rigorous third-party testing to ensure purity, potency, and quality. Cooper Complete stands behind every bottle with lot verification and Certificates of Authenticity available upon request.
