Thorne L Arginine
I used to be able to noticeably tell when the L-Arginine was working, but after taking it consistently, I think I’ve simply gotten used to the effects. I continue to take Thorne L-Arginine daily because I feel it’s beneficial and has become a regular part of my routine.

Not Proven- But For me- helps Blood pressure
I understand that there’s not proven studies about BP with this stuff. I can say this…. I use Thorne stuff quite a bit, have been for several years. Let me say this…. When I’m on my BS and taking horrible care of myself…. I have prescription meds like Losartan for that…. But when I take this daily, it drops my BP a few points. Nothing crazy, but noticeable.

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.

Outrageously overpriced
Good product, but the price has shot up from £40 last month to £80 this month. That's just shameful profiteering. Less than half that price elsewhere, so don't fall for it - check out BigVits and Dolphin.

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.
