    • I recently started using Organnact and WOW—what a difference I’ve seen in my horse! He now has more energy, speed, and rate coming out of the barrels. I’m absolutely in love with these products and will continue using them and sharing with others the impact they’ve had on my horse!

    • I had a reined cow horse/reining mare that really struggled with ulcers. No matter what I tried, she would still go off her feed and be cinchy. After using Organnact Lactobac, she was noticeably happier—fuller through her stomach and no longer cinchy. I highly recommend Lactobac or the GastroEqui pellets to anyone! She also ate them very well, despite being a picky eater in the past. Great products and super friendly people at the show booths. I’ve also used OM Turbo, which significantly improved her recovery after the summer shows.

    • I was hooked on Organnact after seeing the results from the very first product I tried. We have a barn focused on breeding, sales, and show horses, so Organnact has truly been life-changing for us. I’ve confidently recommended these products to friends and veterinarians, knowing they’ll be just as satisfied as I am with the results!

    • I’m very thankful for the results I’ve seen with various Organnact products I purchased from Alessandra. From fitting a 2-year-old filly in preparation for training, to preparing recipient mares for the breeding season, supplementing an orphaned foal, and giving newborn foals a strong start—she has supported me through it all and more. Alessandra has gone above and beyond by visiting my ranch to assess each horse individually and match them with the ideal supplement for maximum results!

      I would just like to say how impressed I am with Organnact products and their customer support! We have used Promun and Lactobac on our foals with great success. This summer, we had a very fast-growing yearling colt that developed tight tendons and soreness in his front legs. Alessandra came to the barn, reviewed the products with us, and recommended adding Corepore Form and Ortho Foals to his daily diet. Within two weeks, we saw a significant improvement in his comfort and structure. We’ve never seen such a big improvement with other ‘leg’ supplements we’ve tried over the years.

    What are the benefits of investing in Organnact® supplements?

    Organnact® is an established company in the Brazilian veterinary market, offering high-quality products for your animals.

    Investing in supplementation improves their nutritional status, appearance, and overall health. Additionally, it ensures significant results for athletic horses by enhancing their performance.

    Organnact® offers supplements for horses in all ages and activities levels. It’s possible to supplement for various reasons, such as nutrition support, foal development, energy during exercise, muscle recovery, support during challenging time, and more. That’s why is never too late to start supplementing your horse.

    Where should I begin?

    It’s possible to start as soon as the foal is a newborn. Promun Newborn is an Organnact® supplement indicated to be the animal’s first contact with supplementation. It contains essential vitamins, minerals, and amino acids to help overcome challenges during this stage.

    What’s the concept of ideal protein?

    All Organnact®’s products are formulated with the concept of ideal protein, which essentially means providing the exact amount of amino acids – without excesses or deficiencies – to optimize protein syntheses and, consequently, muscle mass development.

    What is high palatability?

    Our supplements are extremally palatable, which means they are more easily accepted by your horse. All Organnact® products undergo a rigorous palatability test to guarantee at least 95% acceptance. In other words, only 1 in 20 horses may possibly reject the supplement.

    What is the ideal supplementation dose for my horse?

    The dosage can vary depending on the product formula, the horse’s weight, life stage and level of physical activity. Therefore, it’s crucial to follow the usage instructions provided on the supplement label.

    Can I give a single dose of supplements instead of twice a day?

    We recommend following the dosage instructions provided on the product label. All of our recommendations are developed to attempted your horse’s needs in the best possible way.

    Can I combine two or more supplements at once?

    Absolutely, you can focus on multiple benefits for your horse the same time. There’re no contradictions in combining Organnact® products.

    At what age I can supplement my horses with Organnact®?

    From the very first day of live, as long as the products are suitable for the animal’s stage. At Organnact®, we offer a variety of supplements that can be given to your foal during this crucial stage of development.

    How should I administer Organnact® supplements? Directly on the feed? Can I give it pure? Diluted on water?

    It’s essential to follow the usage instructions on the product label. Most products can be given either pure or mixed with feed, but dilution in water is not always recommend. Therefore, it’s ideal to check the label for specific instructions.
