Good product Effectively works for the purpose it was recommended January 17, 2014
Works for Me! As an addition to my sleep protocol, I found it helpful. I am happy with this product's performance. October 12, 2013
AS MANY LEAVES AS POSSIBLE L-Methionine is a great and wonderful nutrient. I would gladly give it as many leaves as possible, six or seven or eight, etc.. I use it as a Lipotropic Factor along with Choline and Inositol for my liver, heart, cardiovascular system, brain, --- you know, all those little things. Being a high sulfur nutrient, L-Methionine is also wonderful for hair, skin, nails, wellness, and more little things. All those little things add up, which is why I'm so disappointed that Swanson only offers this superior nutrient in small 30 capsule size bottles. What is up with that???? I just ordered 6 more bottles. I take 4, sometimes 6 capsules daily. Ecologically thinking, it would make lots more sense for Swanson to also sell their L-Methionine 500 mg. product in good size bottles, say 90 or 100 for average use, and 180 or 250 capsules for us serious users. It would save money for us customers, and also save on Swanson's packaging costs including bottles, labels, time, labor, etc.. Thirty capsules? That just doesn't make sense to me. What does make sense is taking L-Methionine 500 mg. capsules. . . . at least several every day. METHIONINE IS MARVELOUS. --- Under appreciated, under utilized, yet Uber Marvelous!!! July 7, 2013
Great product I love this product in only this brand. Tried the other brands and they do not work the same for me. If you want longer nails and great skin. This is a start. July 2, 2012
Reasonable product that works! I take this every day. It is helping me to feel better. Did I mention, the price is great. March 30, 2012
L-Methione A cheap mans cysteine. I only buy methione when I am out of cysteine and/or it's not on sale. The body does convert methione into cysteine, so it's a cheaper form of it. How much get converted? That I don't know, but it seems to be an adequate subsitute. July 18, 2011
Vegan delight Good vegan source of the sulfur bearing amino acid so necessary for thiamine,biotin,insulin,mRNA,iron-sulfur clusters in electron-transporting proteins and other important,but not discussed, functions. Few are concerned about sulfur deficiency, but this product will provide good supplementation. April 16, 2009
