Bests & Worsts Reviews from Amazon

No longer pharmaceutical grade. This product no longer contains the Sigma Tau logo. While I endorse taking ALC for those similarly afflicted, I cannot recommend the current version offered under the Jarrow brand. One should look elsewhere to brands sourced from either Lonza ("L-Carnipure" TM) or Sigma Tau ("Biosint" TM), another reputable pharmaceutical grade manufacturer based in Italy. (Doctor's Best source their ALC from Sigma Tau and carry its trademark on their labels. TwinLab, currently one of the most popular brands of ALC on Amazon, sources its product from Lonza -- at least for as long as its label retains the "L-Carnipure" trademark.) In most cases, the brand label will display the words "pharmaceutical grade." The premium charged here is relatively modest (~20%) and well worth it.
