Complete Daily Nutrition with Essential Iron Support

A quality multivitamin serves as nutritional insurance, filling the gaps that even the healthiest diets sometimes leave behind. Basic One with Iron delivers comprehensive daily nutrition in a single, easy-to-take tablet, formulated with premium forms of essential vitamins and minerals plus 18 mg of gentle, highly absorbable iron.

Iron is one of the most common nutrient deficiencies worldwide, particularly among women of childbearing age, endurance athletes, and those following plant-based diets. This essential mineral plays a critical role in producing hemoglobin, the protein in red blood cells that carries oxygen throughout your body. Without adequate iron, you may experience persistent fatigue, weakness, difficulty concentrating, and decreased immune function—symptoms that can significantly impact your quality of life.

Who Needs Supplemental Iron?

While many men and postmenopausal women get adequate iron from their diet alone, certain groups have higher iron needs. Premenopausal women lose iron monthly through menstruation, making supplementation important for maintaining healthy levels. Pregnant and nursing women have substantially increased iron requirements to support their baby’s development. Endurance athletes, particularly runners, can experience iron loss through foot strike hemolysis and increased red blood cell turnover. Vegetarians and vegans may also benefit from supplemental iron, as plant-based iron sources are less readily absorbed than iron from animal products.

Gentle Ferronyl® Iron That Won’t Upset Your Stomach

Many people avoid iron supplements because they’ve experienced the uncomfortable side effects—nausea, constipation, or stomach upset. Basic One uses Ferronyl® iron, a premium form specifically chosen for its superior absorption and gentle nature. This microencapsulated iron is easier on your digestive system while providing effective supplementation, allowing you to get the iron you need without the discomfort often associated with traditional iron supplements.

Premium Ingredients That Make a Difference

Beyond iron, 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. 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 with Iron 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.
