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 produce. 100+ Thorne employees are dedicated to ensuring quality.

Are Thorne supplements clinically Reviewed 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.

Heart palpitations

I loved this product as it is actually working. However it caused often heart palpitations and fast-beating which scared me a lot. After i stopped using the medicine symptoms has stopped. I wonder if someone else has faced this problem.

Sehr teuer und leider eine große Belastung für unsere Gesundheit. Nicht empfehlenswert.

Ich bin mit diesem Medikament überhaupt nicht zufrieden. Es war sehr teuer und meine Erfahrung damit war leider äußerst schlecht. Sowohl mein Mann als auch ich haben es eingenommen und hatten erhebliche gesundheitliche Probleme. Bei mir kam es zu starken Hautproblemen und einer deutlichen Verschlechterung meines Gesundheitszustands, sodass sogar der Notdienst kommen musste.Ich kann natürlich nicht beurteilen, ob alle Beschwerden direkt durch das Medikament verursacht wurden, aber meine persönliche Erfahrung war sehr negativ. Deshalb würde ich dringend empfehlen, vor der Einnahme unbedingt mit einem Arzt zu sprechen.Für mich steht die Gesundheit an erster Stelle. Nach meiner Erfahrung würde ich dieses Medikament niemandem empfehlen. Eigentlich würde ich dafür keinen Stern geben, aber ohne Sterne kann ich die Bewertung leider nicht abschicken.

Why Thorne?

VERY good product... I have been using different products for 30 yrs, but when it comes to L-Arginine, I'm pretty brand-loyal to Thorne. I can feel it working...and I know it is rigorously tested.
