Product Overview

Innovated Respiratory Support

Help your horse breathe easily with Lung EQ™ Pellets. With a palatable blend of antioxidants, herbs, and minerals to help fight airway irritation caused by allergies, bacteria, viruses, or environmental irritants, this targeted formula was specially designed to bolster your horse’s respiratory, lung, and immune health.

Each scoop of Lung EQ contains 20,000 mg of spirulina, an antioxidant-rich superfood algae known for its histamine-lowering and immune-assisting properties, as well as jiaogulan, a Chinese herb that assists in airway dilation for a balanced immune response. Other key ingredients include omega 3-rich flaxseed to promote a normal inflammatory response, plus MSM and vitamin C for lung support.

  • Antioxidant-rich Spirulina and vitamin C encourage lower histamine release while providing lung and immune support.
  • 1,500 mg of Jiaogulan helps to support healthy respiratory performance.
  • 10,000 mg MSM and omega 3 fatty acids from flaxseed support a normal response to inflammation.
  • Low-starch formula ideal for a wide range of horses.
Made in the USA.

Rated 5 out of 5 by from A must for Heaves! I purchased this for a 44 yr old Shetland pony with IR/Cushings who also has heaves. Every time the weather would change he would develop a cough which sometimes progressed into mucus production. He’s used steroids, antibiotics and nebulizers in the past for flare ups. Since using this supplement daily we haven’t had ANY flares yet and it almost been a 1/2 a year! Being a Respiratory Therapist for people I have to say I’m beyond impressed by this supplement!

Rated 5 out of 5 by from Great for Dusty Environments! My horse was on this supplement when we lived in Arizona. The environment there is VERY dusty and windy, and so my boy would get very wheezy. Once I put him on this supplement, the wheezing was GONE. I highly recommend this product to everyone I know who is dealing with heaves and other allergies. My boy is not a picky eater so gobbled this up no problem. Be aware, however, it’s stinky! If you scoop the pellets yourself, your hands will smell like this supplement for days lol!

Rated 3 out of 5 by from Not enough for some… I found this product was useful on horse horse but not enough support for my horse. Both horses are it well which was quite nice!

Rated 5 out of 5 by from Magic I have had a gelding for three years who suffers from seasonal allergies/heaves. In the spring and fall he gets wheezy, coughs and has a runny nose and eyes even with 24/7 turnout, clean soaked hay, and antihistamines. I started feeding this supplement in early March of this year. We are now almost to May and my allergies are horrible but my gelding is doing better than ever with 24/7 turnout, clean dry hay, and NO ANTIHISTAMINES! I can't say enough good things about this stuff. His eyes have never been cleaner and his breathing has never been better as it is today, in the middle of allergy season... I am amazed. I just hope it continues to work this well and it isn't a fluke! If you have a heaves horse, try this stuff.

Rated 5 out of 5 by from AMAZING!!! I have 2 horse that have developed some sort of allergy in the last 18 months; cough, weezing, and shortness of breath. I changed feed, hay turnout etc. I have tried SOOOO many different allergens that have not worked. I decided to give Lung EQ a try because well; I tried everything else. They have only been on it for 2 weeks and WOWZA they are improving already!!!! Not 100% but so much better; this stuff is a life saver/changer for my guys! I look forward to the next few weeks for more improvement. THANK YOU THANK YOU THANK YOU for this amazing product!!

Rated 5 out of 5 by from Uckele Lung EQ I've tried many different products to ease my horse's breathing issues. They didn't seem to make a difference or my horse wouldn't eat them. However, Lung EQ has really made a difference. Been using it for over 3 years now and have been very happy with the results!! Ebony is very comfortable now.

Rated 5 out of 5 by from cut the coughing Hay quality is never a given. This product is a wonderful all-around health supplement, but specifically has helped my equine partners "weather" marginal hay crops. My partner LuLu sends her Thanks! She's also VERY fond of the Equi Treats in Peppermint. Recently gave a bag to my Veterinarian, as they spoil her when we have an appointment.
