Supports Immune Balance & Vitality

Helps Maintain Resilience Under Stress

Vet-Developed, TCVM-Rooted Approach

Immune Support That Builds Over Time

Astragalus and Codonopsis are renowned in Traditional Chinese Medicine for strengthening the body’s natural defenses without overstimulation. Support Immunity offers a gentle, daily way to maintain well-being — ideal for pets who need immune reinforcement, seniors, chronically stressed pets, or those recovering from challenges.

For Immune Compromised Dogs/Cats

Supports a steady, balanced immune response for pets needing extra immune reinforcement.

For Running on Empty

When pets seem depleted — low stamina, recovering from stress, or needing more day-to-day resilience — these herbs help support healthy energy and vitality.

For Extended Stress or Seasonal Challenges

Travel, guests, schedule changes, boarding, weather shifts — prolonged stress can tax the immune system. Support Immunity helps maintain homeostasis.

For Pets Under Long-Term Medical Stress

Especially useful when pets are navigating extended care plans and need extra immune steadiness alongside broader support.

Support Immunity

vs The Rest

Most immune supplements rely on long ingredient lists or mushroom-heavy blends designed for broad wellness. Support Immunity takes a more focused approach: two time-honored herbs selected to reinforce immune strength, support vitality, and help the body stay steady during prolonged stress or immune challenge.

Immune Support

Supports Healthy Vitality

Focused Two-Herb Formula

TCVM Approach (Qi-Supporting Herbs)

Stress-Resilience Support

Vet Formulated & Owned

Targeted, Not Overloaded

Only two meaningful herbs for steady, long-term immune balance.

Long ingredient lists that can dilute potency or aren’t ideal for daily use.

Supports the Body During Ongoing Demand

Built to reinforce immune steadiness during prolonged stress, recovery, or seasonal challenge.

Many immune blends focus broadly on wellness without the same stress-supportive herbal intent.

How to Feed

If you're using powder, you can sprinkle the recommended amount right over every meal. Or you can feed it as a treat– scoop the proper dosage into a small meat patty and roll it up, mix the powder with a small amount of cottage cheese and serve. Or put the recommended scoop into an ice cube tray, add water or broth, and freeze. Give twice a day.
Prefer tablets? Add them right to their bowls at every meal. Or roll them in a prized treat like cheese, a meatball, or dipped in coconut oil.

Why Give it Every Day?

The immune system works around the clock, and these Qi-tonifying herbs work best when provided consistently. Daily use helps maintain balanced immune function, steady energy, and resilience during stress, seasonal changes, and everyday life.

Frequently Asked Questions

Product Questions

Can I give Support Immunity every day?

Yes — this formula is designed for daily, long-term use to help maintain balanced immune function and vitality.

Is this safe for puppies and kittens?

Yes, but start slowly. These herbs are gentle, but young pets should always begin with a half dose and work up as needed.

Can I use Support Immunity alongside other Herbsmith formulas?

Absolutely. Support Immunity pairs well with almost every Herbsmith formula, and many pet parents use it as part of their daily regimen. The only exception is Clear AllerQi, which has a different herbal profile and isn’t intended to be combined with Support Immunity.

Should I choose tablets or powder?

Both provide the same herbal support. Tablets are convenient for dogs; powder is easy to mix into meals for cats or picky eaters.

How long until I notice a difference?

Most pet parents see changes in vitality or resilience within 2–4 weeks, with continued improvement over time.
