Product-by-Product Breakdown
1. Basic Nutrients 2/Day
Thorne’s flagship multivitamin uses active, methylated B vitamins (methylfolate, methylcobalamin) instead of the cheaper synthetic forms found in most drugstore multis. The 2-per-day serving keeps the pill burden low.
What stands out: Methylated folate and B12 are meaningful differentiators for people who have MTHFR gene variants. The capsule count is practical compared to brands that require 4–6 capsules per day.
Cost context: At $1.27/serving, this is roughly 2–3x what you would pay for a Kirkland or Centrum multi, but it undercuts brands like Pure Encapsulations ONE ($1.47/serving). See our Thorne vs Pure Encapsulations comparison for a deeper look.

2. Magnesium Bisglycinate
This is Thorne’s best-selling magnesium, and for good reason. The bisglycinate (chelated) form is known for being gentle on the stomach and well-absorbed. We have a full deep-dive review here.
What stands out: The powder form mixes cleanly, tastes neutral, and delivers 200 mg per serving. Many users report improved sleep quality and post-workout recovery.
Cost context: At $0.53/serving, it is competitive with other chelated magnesium options but notably more expensive than magnesium oxide alternatives from NOW Foods.

3. Super EPA Pro
Thorne’s high-potency fish oil delivers 1,100 mg combined EPA and DHA per serving in a concentrated softgel. It uses a re-esterified triglyceride form for absorption.
What stands out: NSF Certified for Sport. The EPA:DHA ratio is heavily weighted toward EPA (750 mg EPA, 350 mg DHA), which is a profile many practitioners prefer for general wellness support.
Cost context: At $1.87/serving, this is expensive. Nordic Naturals Ultimate Omega runs about $1.10/serving, and Life Extension Super Omega-3 comes in around $0.55/serving.

4. Vitamin D/K2 Liquid
A simple, effective combo of vitamin D3 and K2 (as MK-7) in liquid drop form. Each drop delivers 1,000 IU of D3 and 200 mcg of K2.
What stands out: The liquid format makes dosing flexible. The D3 + K2 combination is increasingly popular among wellness-focused consumers. At $0.14/serving, this is one of Thorne’s best values.
Cost context: This is competitively priced across the board. A genuinely strong value product from Thorne.

5. Creatine
Thorne’s NSF Certified for Sport creatine monohydrate is a staple among athletes subject to drug testing. The formula is straightforward: 5 g creatine monohydrate, no fillers.
What stands out: The NSF Certified for Sport label is the main differentiator. If you are a tested athlete, this matters. If you are not, generic creatine monohydrate at half the price works identically.
Cost context: At $0.38/serving, it is about 2x what bulk creatine costs. You are paying for the third-party testing guarantee.
6. Whey Protein Isolate
A clean whey protein isolate with 21 g protein per scoop, no artificial sweeteners, and NSF Certified for Sport status.
What stands out: The ingredient list is short and clean. Chocolate and vanilla flavors are palatable if understated. Mixability is average.
Cost context: At $2.76/serving, this is among the most expensive whey protein options on the market. Optimum Nutrition Gold Standard runs about $1.30/serving. Unless you need NSF Certified for Sport, the premium is hard to justify.

7. Zinc Bisglycinate
A straightforward 15 mg zinc bisglycinate capsule. The chelated form is gentler on the stomach than zinc gluconate or sulfate.
What stands out: The dosage is conservative (15 mg vs. the 30–50 mg common in other brands), which reduces the risk of copper depletion from long-term use.
Cost context: $0.23/serving is reasonable for a chelated zinc, though NOW Zinc Glycinate at $0.10/serving offers strong competition.

8. Berberine-500
A single-ingredient berberine supplement delivering 500 mg of berberine HCl per capsule. Berberine has become one of the most-searched supplements in recent years.
What stands out: Clean formula with no unnecessary fillers. Thorne uses the standard HCl salt form.
Cost context: At $0.60/serving, it is mid-range. Some brands offer berberine at $0.30–$0.40/serving, while premium formulas with enhanced bioavailability run $1.00+.

9. MediPro Vegan All-In-One
A vegan protein shake with added vitamins and minerals, intended as a meal replacement or post-workout option.
What stands out: Comprehensive formulation that combines protein, fiber, greens, and micronutrients. Convenient for people who want fewer bottles on the shelf.
Cost context: At $2.67/serving, this is premium pricing for a vegan protein. Garden of Life All-in-One runs about $2.00/serving.
Shop on Thorne: Medipro Vegan →
10. NiaCel 400
A nicotinamide riboside (NR) supplement marketed for cellular energy and healthy aging. NR is a precursor to NAD+.
What stands out: The 400 mg dose is higher than many competing NR products (which typically offer 300 mg). Thorne also includes betaine anhydrous to support methylation.
Cost context: At $1.03/serving, this is less expensive than Tru Niagen ($1.67/serving for 300 mg) but more than Life Extension NAD+ Cell Regenerator ($0.73/serving).

90-Day Experience: What I Actually Noticed
Over 90 days of daily use, here is what stood out:
Basic Nutrients 2/Day: The two-capsule format was easy to stick with. No stomach discomfort, which I have experienced with cheaper multis.
Magnesium Bisglycinate: The powder mixed well in water and had a very mild taste. I used it as part of my nighttime routine and noticed my wind-down felt smoother over the first few weeks. See our full article on magnesium supplements for sleep.
Super EPA Pro: No fishy aftertaste or burps. The softgels are large but manageable.
Creatine: No difference from bulk creatine I have used in the past. The product works as expected, but you are paying for the certification, not a different experience.
Vitamin D/K2 Liquid: Easy to dose. One drop in a morning smoothie. Zero taste.
The overall experience was consistent: Thorne products are well-manufactured, easy to take, and free of the off-putting tastes or stomach issues that sometimes come with cheaper supplements. Whether that justifies the price depends entirely on your priorities.

Frequently Asked Questions
Are Thorne supplements FDA approved?
No dietary supplement is FDA-approved. The FDA regulates supplements under DSHEA (Dietary Supplement Health and Education Act), which means it oversees manufacturing practices and labeling but does not approve supplements for safety or efficacy the way it does pharmaceuticals. Thorne manufactures in GMP-certified facilities and uses third-party testing through NSF International.
Is Thorne better than Pure Encapsulations?
Both brands occupy the premium tier and use high-quality, bioavailable ingredients. Thorne offers more NSF Certified for Sport products and a stronger direct-to-consumer model. Pure Encapsulations is widely used in clinical settings. See our full comparison for a product-by-product breakdown.
Why is Thorne so expensive?
Thorne’s pricing reflects bioavailable ingredient forms (chelated minerals, methylated vitamins), third-party testing (NSF, NSF Certified for Sport), clean formulations with minimal fillers, and US-based manufacturing. Whether the premium is justified depends on the specific product and your individual needs. We break this down in our cost analysis.
Can you buy Thorne supplements in stores?
Thorne sells primarily through their website (thorne.com) and Amazon. Limited retail availability exists through select healthcare practitioner offices and specialty retailers. They do not currently sell through major chains like Whole Foods or GNC.
What is NSF Certified for Sport?
NSF Certified for Sport is a third-party certification that tests supplements for banned substances, verifying that what is on the label matches what is in the bottle. It is the certification most recognized by professional sports leagues, the NFL, MLB, NBA, and NCAA. Read our full explainer on NSF Certified for Sport.
Are Thorne supplements third-party tested?
Yes. Thorne works with NSF International for third-party auditing and testing. Select products carry the NSF Certified for Sport designation. Thorne also conducts internal testing at multiple stages of manufacturing.
Final Verdict
Thorne is a legitimate premium supplement brand that delivers on ingredient quality, transparency, and third-party testing. Their best values are the Vitamin D/K2 Liquid, Zinc Bisglycinate, and Creatine (for tested athletes). Their weakest values are the protein products and Super EPA Pro, where competitors offer comparable quality at significantly lower prices.
If you prioritize clean formulations, bioavailable forms, and NSF certification, Thorne belongs on your shortlist. If you are budget-conscious and do not need sport-certified products, brands like NOW Foods and Life Extension offer strong alternatives at lower price points.
Bottom line: Thorne earns its reputation, but not every product in their line justifies the premium. Buy selectively, use subscribe-and-save, and compare on a product-by-product basis.
