When an aging mare starts taking the first few steps of the morning a little stiff, or a beloved goat begins to favor one leg, every owner faces the same quiet worry: how do I keep this animal comfortable, mobile and strong, the natural way? Arthritis & Joint Support and IST by Molly's Herbals answers that worry with two time-tested herbal companions — one built for the joints, one built for the immune system — so you can support the whole animal, not just a single symptom.

Molly's Herbals has been hand-blending natural care for animals since 2002. The two formulas here pair beautifully: Arthritis & Joint Support is a powdered daily supplement that cushions and feeds the joints, while IST (Immune ST, short for Immune Support Tincture) is a liquid herbal extract that helps the body stay resilient through seasonal stress. Together they form the kind of gentle, year-round program owners reach for when they want comfort and vitality without harsh measures.

What is Arthritis & Joint Support, and how does it ease stiff joints?

Arthritis & Joint Support is a plant-based powder designed for safe, long-term joint care. Each tablespoon carries Glucosamine and MSM (Methylsulfonylmethane) at 1,125 mg each, layered into a proprietary herbal blend of Organic Alfalfa leaf (Medicago sativa), Ginkgo (Ginkgo biloba), Nettle (Urtica dioica) and White Willow bark (Salix alba). The blend is built to support joint comfort and mobility, encourage circulation and nutrient delivery to the joints, and offer traditional anti-inflammatory support — the kind of everyday maintenance an active animal can stay on for life.

What sets this formula apart is what it leaves out. It contains no Yucca or Devil's Claw, the ingredients that make many conventional joint blends unsuitable for continuous use. That makes Arthritis & Joint Support gentle and balanced enough for year-round feeding — even, the maker notes, during pregnancy.

How do you feed it, and which animals is it for?

The powder is simply mixed into food or a favorite treat. Daily maintenance servings scale with the animal: roughly 1½ teaspoons for dogs up to 60 lbs, 2 teaspoons for 60–100 lbs and 1 tablespoon for dogs over 100 lbs; about 1 tablespoon for an adult goat; and 3 tablespoons for a horse. To get ahead of stiffness, many owners double the maintenance serving for the first four to six weeks, then settle into the ongoing daily amount. Because the formula is so balanced, it suits horses, goats, dogs and cats alike.

What does IST (Immune ST) do for immune health?

IST — the Immune Support Tincture — is a handcrafted, small-batch liquid extract made to support a healthy immune response and overall resilience. It blends Astragalus, Echinacea, Licorice Root, St. John's Wort and Oregon Grape Root, drawn out with grain alcohol and filtered water so the herbs stay potent and shelf-stable. Owners turn to it for seasonal wellness and everyday vitality across goats, horses, dogs and poultry.

Dosing is flexible and easy to tailor to the situation: about 1 ml per 20 lbs for dogs, 1 ml per 10 lbs for goats, 20–30 ml for horses, and 1 tablespoon per gallon of water for chickens, given one to four times daily depending on need. The tincture is not suggested for cats. Pairing IST with Arthritis & Joint Support lets you tend to both comfort and immune strength as part of one calm, natural routine.

Who is Molly, and why trust these formulas?

Molly's Herbals grew out of one woman's belief in natural health care. Founder Molly Nolte began studying herbs to help her own breathing — developing a blend that, three years on, left her free of asthma symptoms. From there she started formulating remedies for her own animals, simply because nothing herbal for animals existed yet. “What began as a way to share the herbal formulas I used to care for my own animals,” she has said, “has grown into a community rooted in compassion, healing, and trust.” Today the small-batch, USA-made tradition she started in 2002 carries on under new stewardship, with Molly still sharing the knowledge gathered over two decades of holistic animal care.

The Solution Section (FAQ)
What's the difference between Arthritis & Joint Support and IST?

They address two different needs. Arthritis & Joint Support is a powdered daily supplement for joint comfort and mobility, built around Glucosamine, MSM and a blend of alfalfa, ginkgo, nettle and white willow bark. IST (Immune ST) is a liquid herbal tincture of astragalus, echinacea, licorice root, St. John's Wort and Oregon grape root that supports a healthy immune response. Used together they support both the joints and the immune system.

Which animals can use these formulas?

Arthritis & Joint Support is suitable for horses, goats, dogs and cats. IST is made for goats, horses, dogs and poultry, with flexible per-weight dosing; it is not suggested for cats.

Is Arthritis & Joint Support safe for long-term, year-round use?

Yes. The formula is intentionally gentle and balanced for continuous maintenance, and it leaves out Yucca and Devil's Claw — ingredients common in other joint blends that make them unsuitable for ongoing use. The maker notes it is balanced enough to use year-round, including during pregnancy.

How do I feed the joint powder?

Mix it into food or a treat. As a daily maintenance guide: about 1½ teaspoons for dogs up to 60 lbs, 2 teaspoons for 60–100 lbs, 1 tablespoon for dogs over 100 lbs, roughly 1 tablespoon for an adult goat and 3 tablespoons for a horse. Many owners double the serving for the first four to six weeks, then reduce to the ongoing daily amount.

How is IST dosed?

IST is given by weight and can be adjusted to the situation: about 1 ml per 20 lbs for dogs, 1 ml per 10 lbs for goats, 20–30 ml for horses and 1 tablespoon per gallon of water for chickens, one to four times daily. It is not suggested for cats.

What ingredients are in each formula?

Arthritis & Joint Support combines Glucosamine and MSM with a proprietary herbal blend of organic alfalfa leaf, ginkgo, nettle and white willow bark. IST is a grain-alcohol-and-water extract of astragalus, echinacea, licorice root, St. John's Wort and Oregon grape root.

Are these products made naturally and in the USA?

Yes. Molly's Herbals products are all-natural, small-batch and handcrafted in the USA, a tradition the company has carried on since 2002. As with all herbal supplements, the statements about these products have not been evaluated by the FDA and the products are intended for animal use.

How did Molly's Herbals get started?

Founder Molly Nolte first turned to herbs for her own health, developing a blend that eased her asthma. She then created herbal formulas for her own animals because none existed at the time, and began sharing them with others. That grassroots start in 2002 grew into the holistic animal-care brand it is today.
