VetCur Vivo Flex – Advanced Cellular Support for Joints, Mobility & Connective Tissue
Vivo Flex is for the animals who no longer bounce up off the bed, hesitate on stairs, or move with less ease than they once did. It is built for deeper mobility challenges, where the issue is not just stiffness on the surface, but how the body maintains and renews its own tissues over time.
Rather than acting as a quick, feel-good joint formula, Vivo Flex focuses on cellular maintenance and healthy inflammatory balance. It supports the body’s own systems for tissue renewal so joints, muscles, and connective tissues can be better maintained from the inside out.
Every ingredient serves a precise function. No fillers. Built to support mobility, connective tissue maintenance, and healthy inflammatory balance at the cellular level.
Ingredients: Brewer's Yeast, Devil's Claw, Flaxseed, Rhodiola, Dragon Tree Resin, All Heal (Prunella vulgaris).
An animal’s ability to maintain healthy joints and connective tissues is influenced by diet, environment, workload, and internal balance—a concept often described through epigenetics. Over time, chronic physical stress and an imbalanced inflammatory response can change how the body maintains normal tissue function, contributing to stiffness and reduced cushioning.
Vivo Flex is formulated to support the body’s natural gene-expression patterns related to tissue maintenance and healthy inflammatory response. The goal is to help the body sustain more comfortable movement from within, rather than relying only on external or short-term approaches.
Best fed in the evening to align with the body’s natural nighttime repair and regeneration processes, but can also be given before periods of increased physical stress when needed.
Horse Dosage
Adult Horses: 1 scoop (~0.21 oz) per day (~21 days per bottle).
Light Use or Alternating with Other Supplements: 1/2 scoop (~0.11 oz) per day (~41 days per bottle).
Q: Why is Vivo Flex more expensive than standard joint supplements?
A: Vivo Flex is built around a cellular and epigenetic approach to mobility, using a focused combination of herbs and nutrient sources chosen for tissue renewal, inflammatory balance, and resilience. It is designed for animals with more significant or long-standing mobility challenges, and many guardians use it as a targeted protocol rather than a forever supplement.
Q: How can I support my dog’s or horse’s stiff joints naturally?
A: Internal support that addresses inflammatory balance, connective tissue integrity, and cellular maintenance often plays a key role. Vivo Flex is formulated with this whole-body approach in mind, and can be a gentle complement to movement, weight management, and other wellness strategies recommended by your veterinarian.
Q: My dog has arthritis. Is Vivo Flex an alternative to NSAIDs?
A: Vivo Flex is not a replacement for veterinary-prescribed medications. Many guardians seek natural complementary support when they are concerned about long-term pharmaceutical use. Vivo Flex is designed to support healthy inflammatory balance and tissue maintenance alongside veterinary care, not instead of it. Always consult your veterinarian before making changes to your animal’s treatment plan.
Q: What makes Vivo Flex different from a standard joint supplement?
A: Most joint supplements focus on adding structural compounds from the outside. Vivo Flex is built to support the body’s own cellular maintenance processes and internal signaling, helping it sustain healthier tissue function over time rather than simply supplementing around the issue.
Q: Can Vivo Flex be used with other VetCur formulas?
A: Yes. Vivo Flex pairs especially well with ReVet Dog and ReVet Horse for everyday joint comfort, and with foundational protocols such as ViVet or balanced base nutrition.
Q: Is Vivo Flex safe alongside my animal’s existing wellness support?
A: Vivo Flex is formulated with natural ingredients intended to work with the body’s own processes. However, any supplement should be considered in the context of the whole animal. Consult your veterinarian if your animal has existing health conditions or is receiving other medications or supplements.
This product is not intended to diagnose, treat, cure, or prevent any disease. Always consult your veterinarian before starting any new supplement.

Pick a few moments you know well: getting up after a rest, enjoying a walk or reaching a favourite spot. Vivo Flex supports normal joint and muscle maintenance, so those everyday movements are useful things to watch. Keep activity comfortable and compare with your animal’s own starting point.
Sprinkle the label-directed amount over their food. The powder usually clings well to dry kibble; a little water or wet food can help it mix in.
Picky eater? Start with a small amount and build gradually toward the label serving. If it suits their diet, mix with a little plain heavy whipping cream, half-and-half, or a light drizzle of olive oil. Our own dogs often lick the mixture straight from a spoon with a little cream or oil.
Dietary fat helps the body absorb fat-soluble nutrients and some plant compounds. Their regular meals may already provide enough, so added fat is optional.
For dairy-sensitive pets or those needing a low-fat diet, use a little water or familiar wet food instead.
Start with the amount that feels comfortable for your routine and budget. Each product comes in one standard size; the serving guide helps you work out how long it will last. Buying more is optional—you can start with one container and see how the routine suits your animal.
Choose what suits you near Add to Cart: a one-time order, or regular deliveries if a subscription is available. You’ll see the current price and delivery choices before you add it, so there’s no guessing.
Build the routine around what your animal actually needs, using formulas suitable for their species. You don’t have to add everything at once. If you’d like a hand choosing, tell us what they already use and what you’re hoping to support.
If your animal takes medication, is pregnant or nursing, or has a medical condition, check that the ingredients fit their care plan before starting. New, persistent or worsening symptoms deserve a veterinary check; nutritional support works alongside appropriate care.
Before a show, check the current ingredients against the FEI prohibited-substance rules and USEF Drugs & Medications guidance. Some herbal ingredients or their metabolites may be prohibited or detected in testing. Rules can change, so confirm this formula and any withdrawal plan with your veterinarian and governing body. We suggest pausing supplements three days before showtime; however, this cannot guarantee they won’t show up in blood work or urine.
We often suggest the Vivo range when an animal has needed support for a long time—particularly a year or more—and you’d like a more targeted routine. You don’t need to wait a year to ask for help. Tell us what’s been going on and we’ll help you explore the options.
Our suggested routine is ReVet one day and Vivo Flex the next for complementary nutritional support of long-standing mobility needs. Each brings botanical nutrition for normal joint, muscle and connective-tissue maintenance. Use the correct species-specific ReVet and each product’s own label amount. If medication or injury recovery is part of the picture, confirm the plan with your veterinarian first. Explore ReVet and Vivo Flex joint support.
