Thorne produces high-quality supplements through rigorous testing, well-researched ingredient sourcing, and strict manufacturing standards. We avoid unnecessary additives, binders, and fillers that may interfere with nutrient absorption. How does Thorne test its supplements for quality? To confirm the purity of our ingredients, the potency of our formulas, and the absence of all contaminants, we carry out a minimum of four rounds of testing on every product we manufacture. 100+ Thorne employees are dedicated to ensuring quality. Are Thorne supplements clinically tested and safe? Thorne partners with researchers and conducts clinical trials to support the efficacy of our products. Our team of doctors and medical experts substantiate each ingredient in every formula based on extensive clinical research and medical literature. Why are Thorne products more expensive than other supplements? When it comes to the health of our customers, we never settle. Thorne products may be priced higher than some others because of our commitment to quality at every step. We don’t simply meet the standard in dietary supplements — we set the standard. Where are Thorne supplements made and where are the ingredients sourced from? Located in South Carolina, Thorne manufactures supplements in the USA using globally sourced ingredients. When it comes to ingredient sourcing, we seek out only the highest-quality ingredients, selecting each one for its purity and effectiveness.

  • Clean ingredients!
Size: 90 Count (Pack of 1)
Thorne is a wonderful brand with clean ingredients. We take this magnesium before bed and it is wonderful. We have been sleeping better, and it has also helped my husband's blood pressure!

  • Fantastic brand, fantastic benefits!
Size: 90 Count (Pack of 1)
I have been taking Thorne magnesium glycinate nightly for about two months now, and it has become a non-negotiable part of my health routine. Since I am not a big fan of vegetables, making sure I get a highly absorbable, top-tier mineral supplement is incredibly important to me. This chelated formula is fantastic because it is completely gentle on the stomach and absorbs beautifully without causing any digestive issues. The only challenge is that the capsules themselves are quite large. After having them get stuck in my throat a few times, I decided to take matters into my own hands. Now, I simply open the capsule and empty the powder into a half bottle of water, adding a half packet of true lemon crystals to mask the natural chalky taste, give it a shake and drink. The natural citric acid in the True lemon completely cuts through the flavor and makes it incredibly easy and almost pleasant to drink before bed. If you struggle with large pills, this trick works perfectly and doesn’t change how well the supplement works! At almost 59 years old, I have been and still am completely prescription – drug free despite a very heavy family history of early heart issues. My father, Brother and sister all had heart surgeries in their 40s. I am the only one out of the four of us that has had no heart issues. So even if you don’t feel an immediate shift, this high-quality magnesium works quietly behind the scenes to keep your blood vessels relaxed, your heart healthy, and your muscles functioning exactly as they should. Thorne is an incredible brand, and this magnesium is worth every penny for anyone looking to take proactive, independent control of their long-term health. As you can see in the photo, this capsule is quite a bit larger than an average extra strength Tylenol. ... show more

  • Clean Ingredients, Great Price, BEST SLEEP
Size: 90 Count (Pack of 1)
I’m very intentional and particular about the products I use, and compared several brands before purchasing. I’ve been supplementing for 10+ years, using premium quality brands like Nutrilite. I decided on Thorne Magnesium Glycinate because of their clean ingredients, manufacturing integrity, 3rd party quality testing, concentration of magnesium dose and minimal unnecessary ingredients (preservatives, stearates or flow agents). My husband and I have been taking Thorne Magnesium Glycinate for almost 2 months now, and I sleep SO much better at night! I take it about 30 minutes before bed, and I fall right to sleep once I hit the pillow. My husband is more of a night owl and tends to have a harder time falling asleep, but when he takes this he’s out within an hour or two (which is an improvement for his standards!) Great value for the price and great supplement, and about to purchase our next bottle! ... show more

  • Sleep
Size: 90 Count (Pack of 1)
If you’re using this for sleep I’d recommend it, it does put me out within 10 minutes I’d say and lessens up my REM sleep into DEEP sleep, or LIGHT. Some experience “crazy” dreams which I did the first month of using this but afterward you get accustomed and you barely experience any crazy dreams

  • Good quality magnesium supplement
Size: 90 Count (Pack of 1)
I like the quality of this magnesium glycinate and the capsules are easy to take. I’ve been using it as part of my evening routine and it has worked well for me. Thorne is a brand I trust for supplements, and I also appreciate the simple ingredient profile. So far, I’m happy with the purchase.
