Description

Magnesium Glycinate Basic Nutrients Creatine Super EPA Zinc Picolinate 30 mg Berberine Magnesium Bisglycinate What makes Thorne supplements high quality? 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.

  • A Great Addition to My Evening Routine
Size: 90 Count (Pack of 1)
A Great Addition to My Evening Routine I've been taking Thorne Magnesium Glycinate for quite a while now, and it's become a regular part of my evening routine. I started taking it to support more restful sleep, and I've been happy with it. Since becoming pregnant, getting a good night's sleep has been more challenging, so I've especially appreciated having this in my routine. I've also noticed that I seem to have fewer nighttime leg cramps, although I can't say for sure whether that's due to the magnesium. Overall, this has been a high-quality supplement that has worked well for me, and I plan to continue taking it. ... show more

  • Quality Brand!
Size: 90 Count (Pack of 1)
I take this to help me sleep at night and does wonders! I bought it because my other brand was not available and strangely I feel like Thorne is slightly better than my usual brand. I’m sleeping just a bit better than usual - which is helping out with my overall wellbeing! ❤️

  • Best product in the market
Size: 90 Count (Pack of 1)
Best product in the market. I tried the same product from Pure Encapsulation and I had to stop after 2 weeks and switch back to Thorne. My sleep has immediately improved again. The Thorne brand absorbs better.

  • I Like It!
Size: 90 Count (Pack of 1)
Great overall supplement. It doesn't taste too bad, it is rather easy to swallow and I appreciate the fact that the smell isn't too strong. This is a great option for magnesium glycinate!

  • Reliable
Size: 90 Count (Pack of 1)
The brand has a good reputation. I prefer to order products with the Thorne brand than others, because of its reputation. The magnesium by Thorne is well worth the price. It is reputable and for sleep it works well. Other health benefits are included so not just for sleep but overall health. Good product. ... show more

  • Helps with sleep
Size: 90 Count (Pack of 1)
I bought this because I wasn’t sleeping through the night, waking up at 3/4am every night. After two nights of taking this I was sleeping through the night! No side effects, and I have a sensitive stomach. Now I feel 100% better and can tell it’s because I’m getting a full nights sleep.
