Frequently Asked Questions
What is the #1 recommended multivitamin by doctors?
Thorne Basic Nutrients 2/Day is most frequently cited by registered dietitians for its highly bioavailable forms — methylated B vitamins, vitamin D3, chelated minerals — and NSF certification. For budget buyers, Nature Made Multi (USP-verified) is the standard recommendation.
Do multivitamins actually work?
Evidence is encouraging. A large 2024 COSMOS clinical trial found that daily multivitamin use slowed cognitive aging by roughly two years over a 3-year period. Benefits are most pronounced for people with dietary gaps, older adults, vegans, and those with specific deficiencies.
When is the best time to take a multivitamin?
Take your multivitamin with food that contains some fat — fat-soluble vitamins A, D, E, and K require dietary fat for proper absorption. Morning with breakfast is ideal for most people. Avoid taking iron alongside calcium-rich foods as they compete for absorption.
Should I choose a multivitamin with or without iron?
Women of childbearing age typically need iron (18 mg/day). Men and post-menopausal women should generally avoid iron in their multivitamin unless a doctor confirms deficiency — excess iron can cause oxidative stress and digestive issues.
Are gummy vitamins as effective as capsules?
Gummies can be effective but often contain lower doses of key nutrients, more sugar, and fewer minerals. They are a good option for those who struggle with pills, but capsules and tablets typically deliver more complete nutrition per serving.
