Product Information

One of the best nutritional treatments for the Herpes simplexvirus is L-Lysine, a well-known amino acid. L-Lysine is one of the nine essential amino acids that the body needs to manufacture proteins. It is considered "essential" because the body cannot manufacture L-Lysine.

As an amino acid it is involved in tissue repair, production of hormones and enzymes and in the synthesis of collagen and bone health. Most persons get adequate L-Lysine in their diet but those who have problems with the herpes virus may need supplemental L-Lysine to keep the virus in check.

This approach originally came from research showing that lysine has anti-viral activity against the Herpes simplex virus in test tube studies. L-Lysine works to inhibit the growth of the virus by blocking its use of another amino acid - arginine.

In order for L-Lysine therapy to really be effective in preventing cold sores and outbreaks of genital herpes it is important that the diet also is low in arginine. Avoid foods high in arginine like chocolate, peanuts, almonds and other nuts, and seeds. It is also a good idea to focus on foods that are high in L-Lysine such as most vegetables, legumes, fish, turkey, and chicken. Follow these dietary guidelines and take one gram of L-Lysine three times daily with meals for maximum benefit. In one double-blind study, after 6 months, L-Lysine was rated as effective or very effective in 74% of cases compared to only 28% for those receiving the placebo.

L-Lysine also plays a role in helping the body to absorb and conserve calcium, so it may also be important for those who have a predisposition to osteoporosis.

L-Lysine should be an essential part of a nutritional protocol to prevent flare-ups of the herpes simplex virus, in whatever form it may take. Combine therapeutic dosages of L-Lysine with a low-arginine diet and extra nutritional help from vitamin C and zinc for effective control of this virus.

Very pleased with my purchase
Color: Brown, Size: Mid Back
Easy to put together - instructions are good - excellent quality and the chair is comfortable. Far from being flimsy it's a heavy chair which rolls perfectly as needed. You won't find that many good chairs (if any!) at this excellent price. As always the ultimate question is: would I buy it again? The answer is YES, definitively. Great purchase.

superb, worth 2x the pricez
Color: Brown, Size: High Back
While this may appear to be an average run of the mill copycat sort of generic office chair, it's actually very comfortable with perfect lumbar support. Looks great, and the leather (or leather equivalent) feels durable. This sucker will last me in my WFH setup for years I do not doubt. Save yourself a few hundred bucks getting this versus some "premium" office chair... I doubt you'll notice much if any difference.

22 year old gamer approved.
Color: Black, Size: Mid Back
So far so good!! I bought this chair for my gamer son, he sat the springs out of his last one, so this one making it this long has me very pleased. It was easy to put together, and the quality is pretty notable, especially the wheels, super smooth rolling. It was definitely worth what we paid for it, and he finds it very comfortable, providing plenty of back support, and a stable seat for hours of gaming.

The back of the chair is not supportive
Color: Brown, Size: Mid Back
Really nice casters that truly roll quietly. The faux leather is stitched well and sturdy. The only problem i have is that the back is not adjustable and gives 0 back support. The whole back of the chair is hollow inside so your lumbar gets no help. The seat is comfy but super wide like a lot of other reviews mentioned

Stick with Name Brands
Color: Grey
Product arrived as described. I am 47, 5'9" and 195 lbs. I suffer from lower back pain. I am a graphic designer that spends hours in front of the computer. I purchased a less expensive chair, but it made my back feel like it was on fire and I was hobbling around the home like an elderly man. It wa sa gaming chair, with a cool look, but horribly uncomfortable—about $75 less than this chair. I decided on Serta due to the brand recognition and quality of build. The chair arrived without blemish. It's very easy to assemble, taking me about 20 mins. I am very pleased with the look and quality of the leather. The seat cushion and back rest is quite comfortable. Firm, but soft, not too firm, but not too soft. I spend long hours at my desk and so far my back feels great. No burning, no hobbling. It's worth the extra $50-100 in cost. Happy customer.
