Thorne Research is recognized by over 100 professional sports teams for its commitment to ingredient quality and transparency. This dedication extends to understanding exactly what are the ingredients in Thorne multivitamins, which are formulated with highly absorbable, pure nutrients to maximize effectiveness for various health needs.

Quick Summary

Thorne multivitamins utilize highly bioavailable, 'tissue-ready' vitamins and chelated minerals to maximize nutrient absorption and support overall wellness, with specific formulas tailored for different life stages and needs, from basic foundational support to athletic performance.

Key Points

Bioavailable Forms: Thorne uses active B-vitamins, like 5-MTHF instead of folic acid, and chelated minerals (TRAACS®) for enhanced absorption.
Comprehensive Nutrition: Standard formulas, like Basic Nutrients 2/Day, include a wide range of essential vitamins (A, C, D3, E, K) and chelated minerals (Calcium, Magnesium, Zinc, Selenium).
Targeted Formulas: Thorne offers specialized multivitamins for different demographics, such as Multi-Vitamin Elite for athletes and gender-specific 50+ formulas.
Clean and Pure: Thorne products are manufactured without unnecessary additives or coatings and undergo extensive third-party testing for purity and potency.
Specialized Blends: Certain products contain unique blends; Multi-Vitamin Elite includes Meriva®, Green Tea Phytosome, and Relora® to support energy and recovery.

Thorne's Formulation Philosophy: Bioavailable and Clean Ingredients

Thorne Research distinguishes itself in the supplement market by focusing on superior ingredient sourcing, clinically researched formulations, and rigorous manufacturing standards. Their multivitamin products are designed with high absorbability in mind, ensuring that the body can effectively utilize the nutrients provided. This commitment means avoiding unnecessary fillers and using specific, active forms of vitamins and chelated forms of minerals for optimal bioavailability. For instance, rather than standard folic acid, Thorne uses the active form, L-5-Methyltetrahydrofolate (5-MTHF), which doesn't require conversion by the body before it can be used.

Core Ingredients in Thorne's Multivitamin Formulas

A typical comprehensive Thorne multivitamin includes essential vitamins and minerals in highly bioavailable forms. For example, the Basic Nutrients 2/Day contains a full B vitamin complex with active forms, Vitamins A, C, D3, E, and K. Minerals are often chelated using Albion® technology for better absorption and may include Calcium, Magnesium, Zinc, Selenium, Copper, Manganese, Chromium, Iodine, and Boron.
