NOW Supplements, L-Lysine (L-Lysine Hydrochloride) 500 mg, Amino Acid, 250 Tablets

Arrived quickly, no gross taste, inexpensive and does the job.

Ive battled fever blisters forever, since I was a little kid. In doing some research I came across people saying that Lysine can help prevent them. At first sign of feeling one coming on, or even if I just know that Im feeling run down and I might have one pop up as a result, I take four of these. I havent had but maybe one fever blister since, and I was breaking out regularly for a while. Glad I found this.

These are a great vitamin supplement.

I have been reading a very useful book - ‘Restoring Your Digestive Health’ - by Jordan S Rubin and Joseph Brasco, both MDs. They have a section titled ‘Sub-Par Supplements’ in the book, and interestingly, this section lists amino acid supplements. Many Amino acid supplements are sold to athletes and bodybuilders to help them build muscle strength. The problem with these supplements, however, is that they are a far cry from the amino acids in food. In the protein from food sources, different kinds of amino acids are bound together in long molecule chains, but in supplements the amino acids are free form or unbound. Each type of amino acid is sold as an isolate. Research suggests that these isolate, free-form amino acids are not absorbed adequately. Cofactors present in food sources probably help the body metabolize amino acids, but those cofactors are not present in free form amino acids. As long as you are getting enough protein in your food, you do not need to take amino acid supplements. Consume lacto-fermented foods and take high quality digestive enzymes to improve your protein digestion if you feel that you are deficient in amino acids. In general, we do not recommend these supplements for most patients.

These keep my recurrent shingles under control. When I miss a day, I usually start to have a flare

Starting taking and I’m already feeling a lift in my mood and energy, maybe just the placebo effect but still solid.

Lower prices

I used this brand for two years but recently had to change. They’ve done something different and the last two auto deliveries I’ve gotten of this was not the same as the product I used for two years. It’s smells like rotten milk now and makes me gag . Save your time and money and stay clear of it.

Ive been taking L-Lysine since 1968 and dont get sick. Getting scheduled vaccines and a good diet also help.

Now is a reputable and fairly priced brand. Ive never experienced any problems with Now. I use L-Lysine as an immune system booster and this brand works well.
