Basic Nutrients 2/Day Ingredients
A line-by-line look at what's inside Thorne Basic Nutrients 2/Day, including active components and excipients.
Thorne's design philosophy on Basic Nutrients 2/Day is restraint — fewer mega-doses, more attention to the active forms of each nutrient, and deliberate omissions (no iron, no calcium) so practitioners can layer in those minerals separately based on labs. Each 2-capsule serving covers 23 nutrients in clinically-relevant doses without resorting to stimulant-style B-vitamin levels.
Active Ingredients
The active ingredients break into four functional groups: fat-soluble vitamins, water-soluble (B-complex + C), minerals in fully chelated forms, and a small set of trace elements.
- Vitamin A (as 50/50 retinyl palmitate + mixed carotenoids) — preformed and provitamin A, balanced
- Vitamin C (as ascorbic acid) — modest dose; Thorne assumes most users layer in additional C if needed
- Vitamin D3 (cholecalciferol) — 1,000 IU per 2 capsules; conservative dose, intentional
- Vitamin E (mixed tocopherols) — full-spectrum, not just alpha-tocopherol
- Vitamin K1 (phylloquinone) + Vitamin K2 (MK-4) — both forms; MK-4 is the version associated with bone and arterial calcification research
- Thiamin, Riboflavin, Niacin (as niacinamide), Pantothenic acid — standard B-complex backbone
- Vitamin B6 (as pyridoxal-5-phosphate, P5P) — active form, no conversion needed
- Folate (as L-5-methyltetrahydrofolate, 5-MTHF) — methylated active form, bypasses MTHFR variants
- Vitamin B12 (as methylcobalamin) — methylated active form
- Biotin — standard dose for hair/skin/metabolism
- Iodine (as potassium iodide) — supports thyroid function
- Magnesium (as bisglycinate, well-tolerated, well-absorbed) — chelated form
- Zinc (as bisglycinate) — chelated; balanced against copper
- Selenium (as Se-methylselenocysteine, SeMSC) — bioavailable selenium, not selenium yeast
- Copper (as bisglycinate) — small dose, balanced against zinc
- Manganese (as bisglycinate)
- Chromium (as nicotinate-glycinate chelate) — supports glucose handling
- Molybdenum (as glycinate) — cofactor in detox enzymes
- Boron (as glycinate) — bone/joint support trace mineral
Other Ingredients (Excipients)
Thorne is unusually clean on excipients. The capsule is hypromellose (vegetable-derived). Other ingredients are typically calcium laurate, silicon dioxide, leucine. No magnesium stearate (Thorne's house position is to avoid it). No artificial colors, flavors, or sweeteners. No common allergens.
Allergens and Sensitivities
Thorne explicitly markets Basic Nutrients 2/Day as free of major allergens: no wheat, dairy, soy, egg, fish, shellfish, tree nuts, or peanuts. The formula is also gluten-free certified. People with a sensitivity to methylated B-vitamins should still review the label — methylcobalamin and 5-MTHF are present and active. The capsule excipients are hypoallergenic but not zero — anyone with severe MCAS or histamine sensitivity should still test cautiously.
Sourcing and Quality Notes
Thorne operates from Summerville, South Carolina, with manufacturing at its Yuba City, California facility. The brand emphasizes a few quality-positioning differentiators that set it apart from drugstore multis: NSF Certified for Sport (which means the entire facility is third-party tested for banned substances and contaminants), partnership with Mayo Clinic Healthy Living Program, and independent third-party testing of every batch. The NSF Certified for Sport mark in particular is why Thorne is the reference brand for elite athletes, the U.S. Olympic & Paralympic Committee, and many professional sports teams.

How Ingredients Compare to Similar Products
Thorne Basic Nutrients 2/Day is most directly compared to Pure Encapsulations Polyphenol Nutrients, Designs for Health Twice Daily Multi, and Garden of Life Vitamin Code Raw Whole Food. Against Pure: similar quality bar, similar methylated B-vitamins; Pure adds more polyphenols. Against Designs for Health: similar foundational positioning; DFH includes a small amount of iron. Against Garden of Life: GoL is whole-food-form; Thorne is precision-form. Against Centrum (the drugstore reference point): Thorne uses active forms of B-vitamins (Centrum uses cyano- and folic acid), fully chelated minerals (Centrum uses oxides and sulfates which are cheaper but less absorbable), and is third-party-tested NSF Certified for Sport (Centrum is not). The price gap reflects that — Thorne is roughly 4–5x the price of Centrum per dose.
