  • Product Description

    Puur L-lysine

    Puur L-Lysine is a food supplement that supports the immune system. L-Lysine is an amino acid, which is important for the production of elementary bodily proteins. In addition, it promotes growth and supports the tissue thanks to its collagen-forming qualities and its ability to absorb calcium. The added Vitamin B6 supports a healthy immune system. In addition, Vitamin B6 supports the body's ability to absorb L-Lysine.

    Recommended for

    • Dogs, cats and horses
    • Weakened immune system
    • During recovery periods, for example after surgery
    • Change due to new environment

    Pure L-Lysine for dog and cat

    Pure L-Lysine is a supplement that can be used to boost your dog's or cat's resistance. Especially in the case of viral infections (herpes virus) of the upper respiratory tract, this is a good choice. Think, for instance, of kennel cough in dogs and sneezing disease in cats. 

    But besides increasing resistance, lysine has been proven to support stress, muscle weakness, improve iron and calcium absorption in the gut and a healthy musculoskeletal system. 

    For dogs and cats, choose the 50g jar with a 1g measuring spoon. If you want to use the product for longer, you can choose the larger 500-gram pack. The composition is the same. Keep the measuring spoon for easy dosing for dogs and cats. 

    Pure L-Lysine for horse

    As in dogs and cats, L-Lysine can be used to good effect in horses for anterior respiratory infections based on a herpes virus, such as rhinopneumonia. It can also be used in horses for tissue repair and strengthening of connective tissue, bone and muscles through collagen production and improved absorption of iron and calcium. 

    For horses, choose the 500-gram jar with a 5-gram measuring spoon.

    Note! The included scoops differ in size per packaging. Is this your first time using Puur L-lysine? Pay attention to which packaging is easier to use.

    Administration

    This supplement can be given with food. You can moisten the powder so that it cannot be blown out of the food bowl. During pregnancy or lactation, please consult with your veterinarian before use.

    Is it not possible to spread out the daily recommended dosage over multiple times a day? It's no problem to give the daily recommended dosage at once. Keep in mind that the desired result may take a while, even a couple of weeks. 

    Duration

    In acute situations, the treatment duration is relatively short. This may vary from a few days to 3 weeks. When you notice an improvement, you can continue to administer this product for a few more days. In the event of long-term discomfort, the effect is usually visible after 1 to 3 weeks. Once you notice an improvement, you can move to a maintenance dose. We recommend that you insert a stop week after every 6 to 8 week treatment period. This allows you to reintroduce the stimulant after the stop week. Resume treatment immediately if necessary. This product can be given indefinitely.

    Composition

    L-Lysine, magnesium citrate and Vitamin B6.

    The composition of dog/cat and horse is identical, only the contents are higher because a horse requires a significantly higher dosage. However, you can also use the 500 g version for your dog or cat.

    Storage

    Keep out of direct sunlight and store in a dry place with temperatures between 5 and 20 degrees Celsius. Keep out of reach of children. Expiration date is printed on the label and packaging.

    Puur L-Lysine - 50g

    British Shorthair male cat with a chronic sneezing condition. Following the vet's advice, I give him l-lysine daily. I mix it into a creamy treat. When he's doing well, I give a small scoop. If he has symptoms, I increase the dose or give it more often throughout the day.

    Puur L-Lysine - 50g

    After many examinations, it turns out the not eating behaviour is due to cat flu. Sneezing, breathlessness, the cat can’t smell her food, so she won’t eat. I now use L-Lysine daily, which is quite a drama to squirt into her mouth, but the symptoms are less severe. The illness can’t be cured.

    Puur L-Lysine - 50g

    This is the best lysine supplement yet - we tried a tuna flavour paste - worked for a while, then the cat started to refuse food with it added, we tried chewy 'treats' but he is an old boy and they were too tough to chew, so he stopped taking them too. This is a flavourless powder, easily added to food, and he is very happy to eat food with it added.
