Some theorize that organic supplements may be more effective at raising blood levels of vitamins and minerals than synthetic formulations. A randomized controlled trail published in the journal Current Developments in Nutrition in April of 2026 found this is not the case.
Organic vitamins are derived from organically grown foods or from algae or microorganisms. They are extracted and filtered and undergo quality-assurance procedures. Synthetic vitamins are made from nonfood materials. Vitamin molecules may be formed through chemical processes in labs to match the naturally occurring molecular structures. Minerals (like iron and zinc) can’t be synthesized in the lab but may be extracted from rocks, for example.
The study gave 62 healthy participants either an organic or synthetic multi-vitamin-and-mineral supplement for 30 days. Both supplements provided 60 percent of the recommended dietary allowance (RDA) of each vitamin (vitamin B12, biotin, vitamin C, vitamin D3, and folate,) and mineral (calcium, chromium, iodine, iron, selenium, and zinc). Blood levels of these vitamins and minerals were measured before the supplementation period, two hours after ingestion, and at the end of the 30-day study period.
