Focus Support for Horses

Looking for focus support for your horse? We start with ImmuBiome Focus—daily nutritional support for a cooperative, settled horse through training, travel, shows, and barn stress. Nerve Boost is a good add-on when nerve support is part of the picture.

These supplements are for nutritional support only. They are not intended to diagnose, treat, cure, or prevent disease. Work with your veterinarian for clinical care.

EQUINE FOCUS · STEADY MOOD · NERVE SUPPORT

Training days, trailering, and busy barn routines go better with a settled, cooperative horse. Two formulas live here, and they overlap a little: Focus is our everyday pick for focus and a steady mood, with Reishi, Chaga, and magnesium, while Nerve Boost adds extra Lion’s Mane for horses whose sensitivity seems to come from the nerves themselves. Start with one, and let your veterinarian help shape the plan.

Not sure which formula fits? Answer three quick questions about your horse and we’ll point you to the right place to start.

For the horse who needs help settling in

Show nerves, trailer days, and busy barns—everyday support for a steadier, more focused ride

Steady focus

Daily nutritional support for a settled mind and cooperative attitude during training, handling, and barn routines.

Travel and show stress — gray horse looking out of a trailer

Travel & show stress

Help your horse stay composed when trailering, shows, new environments, or busy schedules add stress to the day.

Nerve and balance support — Reishi, Lion’s Mane, Chaga mushrooms, and Nerve Boost

Extra support for show days

Some horses need focus support; others are more sensitive and reactive. Nerve Boost brings organic Lion’s Mane and prebiotics for everyday nerve function, and it can sit alongside Focus when you want both.

Why ImmuBiome Focus for horse focus and mood

Our go-to for focus and a steady mood

We start with ImmuBiome Focus because it pairs gentle botanicals with mineral and mushroom support—Reishi and Chaga mushrooms, magnesium proteinate, and complementary ingredients designed for everyday emotional balance and trainability.

Where does Nerve Boost fit? It overlaps with Focus on the mushroom side, but its job is different: extra Lion’s Mane for healthy nerve function. Pick Focus when attention and mood are the main goal, Nerve Boost when sensitivity or nerve comfort is the bigger worry, or feed both if your vet agrees.

Use either as part of consistent feeding and your veterinarian’s wellness plan. For diagnosis, treatment, or medication decisions, always partner with your veterinarian.

Great results for anxious 8 yr. old QH

I started my 8 yr old green off-the-track QH on Focus 8 weeks ago because he was extremely watchful (watchy) and highly reactive to new sights and sounds. He also had a bad case of separation anxiety. Focus has soothed his behavior tremendously, and his training has progressed wonderfully. Thank you!

Focus! It really helps

I have been adding Focus to my mare’s feed for a few months now and I truly believe that it is helping her stay more relaxed and focused. She will always be her “looky” and spicy self, but now I am able to redirect her and keep her attention so much better. She is a joy to ride now and not such a challenge! Thank you Immubiome!

Amazing Supplement

This is the first product that has actually helped with my geldings anxiety. I have tried every other calming supplement but this is the first and only one that has worked for his anxiety. Highly highly recommend it for anyone with an anxious horse!

Emotional Balance

Focus has been a great supplement for, what appears to be, calm on the outside, but introverted Dales Pony who is aware of everything. The worry made gut health fragile. It's a great balance of exactly what she needs and seems to be less worried about things too

Great product. Horse is eating it daily and it’s helping the baby brain stay focused. She’s also on lean muscle and seeing fast improvements in body scale

Happy with this

My mare just finished a weekend-long away show. She's always an easy traveler, but she handled the travel and stabling better than ever. She has had a small setback with her hunters over fences. She was way more focused this show and handled "mistakes" with a great attitude. It all paid off in the show ring. In the top ribbons all weekend!

Great for Rehabs

I started my mare on the Focus supplement since she was having a hard time staying calm after she was injured. The Focus has made her much easier to handle and reduced the risk of reinjury.

Love Love Love

My horse has a lot of anxiety, she tilts her head, and will pull on the reins. She has been using the FOCUS for 3 weeks and I swear she has stopped the rein pulling. She seems calmer and happier!

The natural ingredients are what sold me. She loves it and so do we 💜💜💜💜

High quality, reliable results

I have had my mare on Focus for more than 5 years. I increase her dosage a small amount when she is cycling and notice an improvement in her demeanor in general. I am very happy with Focus. I especially like that there are no unnecessary ingredients in this product. Thank you.

Focus

I’ve been using the focus supplement for a little over a year now. It helps my now 6 year old Dutch Harness gelding tremendously. He used to be very tense and anxious but with the focus supplement he is able to *focus* more on me and allow me to guide him through his training. I don’t know what I would do without it!
