Keeping a senior horse fit: Mobility and joint health in old age

Why we find this topic so important: From practical experience, for practical use

Katja and Andrés are the people behind nuvallo. With over 20 years of practical experience in equestrian sport, we know only too well how significantly the needs of horses change as they age. In this article, we give you scientifically sound answers straight from practical experience about what happens in the ageing horse's body and how you can support them in the best possible way.

The knowledge base: What happens in the horse's body as it ages

To understand how we can help our seniors, we need to take a quick look beneath the coat. A horse's joint is a biological masterpiece. Imagine it like the suspension of a car: the articular cartilage acts as a shock absorber that cushions the immense force of every step. The synovial fluid (synovia) is the engine oil that ensures everything glides smoothly and the cartilage is supplied with nutrients.

In younger years, this cycle of wear and regeneration works entirely on its own. But the older the horse gets, the slower its metabolism works. The body naturally produces fewer essential building blocks such as its own collagen or hyaluronic acid. The synovial fluid becomes thinner, the cartilage loses elasticity and becomes brittle.

The treacherous thing about this is that these processes initially happen completely silently. Many of us only notice it in the cold, wet season. The older horse is stiff when coming out of the stable in the morning or needs significantly longer in the paddock to warm up. We also often observe, with a heavy heart, that the older horse finds it harder to get up after lying down to sleep.

These changes are part of the natural ageing process. However, the problem for us as owners is that our basic forage – i.e. hay and grass – simply does not contain sufficient quantities of these highly specific building blocks, which the joint now urgently needs from the outside. This is where targeted feeding comes into play.

What does the science really say?

When we look around the market for feed supplements, big terms are often thrown around. But what is proven fact and what is merely clever marketing? To shed light on this, we must honestly divide the research landscape into three areas.

a) What is proven in laboratory studies

The biological foundation of many active joint ingredients is exceptionally well researched. Cell cultures (so-called in vitro studies) have been investigated at numerous renowned institutes worldwide. Here, scientists apply active ingredients such as glucosamine or hyaluronic acid directly to isolated cartilage cells (chondrocytes). The results here are often impressive: the cells are stimulated, produce more synovial fluid, and cartilage degradation is slowed down.

However, the honest truth also includes this: a petri dish in a laboratory is not a 500 kg horse. When a horse eats an active ingredient, it first has to survive the long journey through the gastrointestinal tract, be absorbed by the blood, and finally transported into the joint. So, laboratory results are a wonderful indicator that a substance works, but they do not yet guarantee an effect on the yard.

b) What has been studied in the living horse

Things get more exciting with clinical studies on real horses. Universities such as Texas A&M or Michigan State University have been conducting research in the field of equine joint health for years. In practical field studies, often conducted over a period of 8 to 12 weeks with groups of 15 to 30 horses, vets measure parameters such as stride length, gait, or the reaction to flexion tests.

Many of these studies confirm: horses that were specifically fed high-quality joint building blocks showed improved mobility values in objective measurement procedures compared to control groups. This picture is complemented by huge human studies. In the well-known GAIT study (Glucosamine/chondroitin Arthritis Intervention Trial), for example, over 1,500 human patients were examined. Such large-scale studies scientifically underpin the effectiveness of the substances. However, we must also be honest about the limits of equine research: for cost reasons, many equine studies have rather small sample sizes or lack huge, independent control groups.

c) An honest conclusion

Overall, the research landscape is very positive and the biological foundation is absolutely solid. But let's not kid ourselves: joint supplements are not miracle cures. Anyone who claims that a feed supplement cures advanced arthritis and turns a 25-year-old pensioner back into a Grand Prix horse overnight is lying. Destroyed cartilage cannot simply be magically restored.

However, especially for the joints of a senior horse, these nutrients are an extremely valuable building block to support the remaining tissue in the best possible way, stimulate the production of synovial fluid, and promote a general joy in movement. Research strongly suggests that these active ingredients work best when they are intelligently combined.

Dosage and practice: What you need to look out for

A glance at the back of many supplements often causes horse owners to frown. How much of an active ingredient does my horse actually need?

In isolated studies, where only a single active ingredient (e.g. pure glucosamine) was tested, researchers often work with very high single dosages of up to 10 grams per day. In practice, however, it has been shown that such mono-preparations are often less effective than intelligent combinations. Due to the synergy effect of different active ingredients (more on this in a moment), the single dose per substance in a combination product can be significantly lower to achieve the same or even a better effect.

In practice, we often recommend a clear distinction between a maintenance dose and an acute phase (course). If you want to maintain the mobility of an older horse, you continuously feed a moderate daily dose. However, if the horse is experiencing acute phases or if you are just starting with the supplement, it makes sense to give double the amount for the first 2 to 3 weeks to initially replenish the body's reserves.

A critical look at the market is essential here: unfortunately, EU Regulation 767/2009 on the placing on the market of feed allows manufacturers to hide the exact amounts of active ingredients per kilogram or per daily dose behind vague phrasing. Often, only percentage ranges or general compositions are stated. As a consumer, however, you should know exactly how many milligrams of a valuable substance actually end up in your horse. Transparency is the be-all and end-all here.

Furthermore, patience is required. Articular cartilage and tendons belong to the so-called bradytrophic (slowly nourished) tissues. It often takes weeks for the nutrients to reach the joint and for the gait to show noticeable support. Expect at least 8 to 12 weeks of consistent feeding before making a final judgement. Many owners often observe the first positive changes after just 4 to 6 weeks.

Why individual active ingredients alone are often not enough: The power of combination

If we want to support our horse's joint holistically, it is not enough to just turn one screw. Imagine a house: if the roof is leaking, the foundation is wobbly, and the windows are missing, it is no use buying tonnes of bricks for the roof but forgetting the cement for the foundation.

Different joint structures need different nutrients. This is exactly where we come in with the nuvallo move Snacks. In the recommended daily ration (6 snacks, approx. 30 g for a 500-kg horse), we specifically combine four essential building blocks:

1. Glucosamine (1,500 mg): The most important building block for cartilage formation. It supports the natural shock-absorbing function of the cartilage.

2. Collagen (2,550 mg): An essential structural protein that provides the necessary elasticity and stability in the connective tissue, ligaments, and cartilage.

3. MSM (2,250 mg): Organic sulphur that plays a key role in the body in the regeneration of tendons, ligaments, and muscles.

4. Hyaluronic acid (150 mg): The main component of the synovial fluid (synovia). It makes the "engine oil" smooth again.

That such a combination of different ingredients is superior to isolated high single doses is proven, among other things, by a well-known crossover study by the British Animal Health Trust. In this elaborate study design – where the horses alternated in phases between a placebo and a combination supplement – the synergy effect was clearly evident. The combination of different joint building blocks led to measurably better results in gait than isolated administrations. A well-coordinated combination product therefore does not need extreme single doses, because the ingredients mutually support each other in their bioavailability.

The biggest challenge in practice: Feeding

We can lecture for hours about milligram amounts, hyaluronic acid chains, and studies. But all that theoretical knowledge vanishes the second we stand in the stable in the evening and our horse simply refuses it. Anyone who has ever tried to get a joint powder into their horse knows exactly what we are talking about.

The feeding problem

Most effective joint supplements have one thing in common: to the horse, they taste bitter, smell strong, or have an unpleasant sandy texture. So, what do we do? We start using tricks.

You stand in the feed room and elaborately mix up some mash. You mix the powder in. You serve it to your horse, they sniff it – and turn their head away. The next day you grate an apple or painstakingly hide the powder in half a banana. Sometimes this works for a few days. But horses are masterful sorters. They manage to unerringly eat the apple and leave the powder lying around it. In the end, you scrape the fine, sticky powder residue from the bottom of the feed trough and have no idea how much of the outrageously expensive supplement your horse has actually ingested.

The emotional frustration is huge. You want to do something good for your old partner, you buy expensive products, and every evening you stand questioning in front of the trough. Aside from that, many powders are enormously dusty, irritate the respiratory tract, or alter the consistency of the hard feed so much that even greedy horses go on strike.

Why we did away with powder

Exactly out of this frustration, which we have shared with our own horses and in conversations with hundreds of horse owners, we completely rethought things at nuvallo. The crucial question for us was not: "How do we make a powder that tastes a bit better?" The question was: "How do we ensure that every horse ingests the full dose reliably, accurately, and with joy?"

The solution is our nuvallo move Snacks. We have turned the highly dosed active ingredients into a functional joint snack that you can simply feed directly from the hand like a reward. When looking for the right joint supplement for your older horse, this means: no more weighing out, no more dusty powder, no more sorted-out leftovers in the trough.

Our snacks are absolutely gentle on the stomach and free from wheat and corn. The base consists of linseed cake, rice bran, and linseed, supplemented by natural ingredients such as banana, apple, and carob powder. This recipe ensures an extremely high acceptance and palatability. The horse no longer sorts anything out because they simply view the snack as an absolute highlight of the day.

With every single snack, you have absolute control over the dosage. If you feed a horse weighing around 500 kg the recommended 6 snacks a day, you know down to the milligram that the glucosamine, collagen, MSM, and hyaluronic acid have 100% ended up inside the horse's body. For lighter horses, you reduce this to 4 to 5 pieces; for heavier draught horses, you go up to 7 to 8. In the first few weeks of the acute phase, you simply double the amount – everything directly from your coat pocket, completely without preparing any mash.

When it comes to the topic of retired horses, feeding, and joints, we have received countless pieces of feedback from owners breathing a sigh of relief. Many report to us: "Since we started feeding nuvallo, we see that our horse is moving more smoothly again and walking with more joy."

Because in the end, the best supplement is not the one with the longest list of ingredients on the label or the highest laboratory value in the test tube. It is the one that actually gets into the horse.
