Pros: Cats like the taste ..
Cons: They treats get hard after awhile and cats won't eat them ..
They are expensive too ..
Pros: Better value than Enisyl-F; cats love them; includes DMG
Cons: Brewer's yeast is an inactive ingredient
Because using lysine in the form of treats is not cost-effective, I typically don't use lysine treats for my indoor-only cats, I use the powder (which has the added benefit of no additional "inactive" ingredients). I care for a feral colony, and two of the cats have ongoing problems with herpes flare-ups. I needed a solution that works for them, and most people feeding ferals provide dry food so powder doesn't work, and when feeding canned or raw, there's no guarantee any one cat will finish any given meal. So lysine treats it had to be.

Many on TCS use Enisyl-F by Vetroquinol. Perhaps it was the first one available. But in comparing the cost, even though the Vetri-Science Vetri-Lysine treats are 120 bite-sized chews vs.180 bite-sized chews for the Enisyl-F, and the Vetri-Lysine bag weighs 5.29 ounces, and the Enisyl-F bag weighs 6.35 ounces, the Vetir-Lysine treats are more cost-effective because of the amount of Lysine.

Vetri-Lysine Plus treats: 2 chews = 250mg of lysine. 120 chews per bag means there are 60 "doses" with a total of 15,000mg of lysine in the bag. On Amazon, the cost per bag is $13.23 (excluding shipping, which is free if you order more than $25 worth of product), or $0.22 per 250mg dose (as of March 23, 2013).

Enisyl-F treats: 5 chews = 250mg of lysine. 180 chews per bag means there are 36 "doses" with a total of just 9,000mg of lysine in the bag. On Amazon, the cost per bag is $11.94 (plus $2.91 shipping, doesn't qualify for free shipping). Excluding shipping, the cost is $0.33 per 250mg dose (as of March 23, 2013).

I've tried both, and the cats love both. But not only are the Vetri-Science Vetri-Lysine plus treats more cost-effective, the "Plus" is because the product includes Dimethylglycine, "an intermediary metabolite that is naturally produced in the body in small amounts during the methylation process. Vetri-Science[emoji]174[/emoji] Laboratories holds four U.S. patents on DMG, backed by 20 years of extensive research."

As Vetri-Science explains, "DMG provides essential building blocks, including methyl groups, that in turn support the body’s production of such important substances as hormones, vitamins, neurotransmitters, nucleic acids and antibodies. It supports the immune response through contributing those methyl groups to bodily processes which require them.

DMG is not an immune system booster. Instead, research indicates that DMG supplementation works to support oxygen utilization on a cellular level, meaning it supports cell health, membrane elasticity, etc. It does not up or down regulate the immune system, but instead is referred to as an adaptogen."

So with the Vetri-Science Lysine Plus treats for cats, you provide both lysine and DMG that helps support - but not "boost" immune system function.

The only drawback is the inclusion of brewer's yeast as an inactive ingredient. Some kitties are allergic or sensitive to yeast, so this should be noted.

Comments

It's ever so much easier an cheaper to get the lysine in human capsules which yu can open and sprinkle some in their food.  It has lottle taste, a little salty.  TWIN LABS sells it in capsule form and can be found in the HEALTH section of Kroger (the lysine in their regular section is always the tablets).
