ThorneBasic Nutrients 2/Day

Overview

Most multivitamins are designed around price. Thorne's Basic Nutrients 2/Day is designed around forms and testing. A two-capsule serving provides 2,000 IU (50 mcg) of vitamin D3, 200 mcg each of vitamin K1 and K2 (as MK-4), 600 mcg of B12 as methylcobalamin, folate as L-5-MTHF, 15 mg of zinc and 200 mcg of selenium, with minerals in chelated bisglycinate forms. It contains no iron, which suits most men and many active women who get iron elsewhere, and it covers a broad spread of B vitamins, vitamin C, vitamin E, iodine, chromium and boron.

On paper, this is a thoughtfully formulated foundation. The standout for athletes is quality: the product is NSF Certified for Sport, which Thorne describes as testing for label claims and screening for nearly 300 substances banned by major athletic organizations.

What reviewers say

Reviewers are broadly positive. Athletic Insight's 100-day review praised the chelated minerals, active B vitamins and NSF testing, reported no digestive upset and called the price in line with other premium multis. Dr. Bell called it a well-designed daily multi without much filler, one Dr. Bell often recommends to patients. Fitness creator skfitness picked it after a mineral test showed gaps, citing Thorne's reputation. On TikTok, creator daddyczap highlighted the NSF certification and recommended taking it with food. The main caveats are the premium price and that people with nutrient-dense diets may only need one capsule.

Who it's for

Drug-tested athletes, lifters who want a no-guesswork daily foundation, and anyone who prefers active forms of B vitamins. If you take anticoagulants, the vitamin K content means you should talk to your doctor first.

Bottom line

Premium, but for good reason. If you want one multi you never have to second-guess, this is it.
