Unlocking Vitality: Why Ageing Dogs Benefit from Protein, Probiotics, Amino Acids, and More – A Deep Dive into Jayfuel Hench RangeAs dog owners in the UK, we cherish our furry companions as they grow older, watching them transition from playful pups to wise seniors. But with age comes challenges like reduced mobility, muscle loss, and digestive issues. If you're searching for the best supplements for ageing dogs in the UK, you're in the right place. Today, we're exploring how key nutrients like protein, probiotics, and amino acids can transform your senior dog's health – and spotlighting Jayfuel Hench Range, a high-protein muscle health supplement that's making waves for dogs of all ages.


Available at Advanced Animal Care, this vet-approved formula packs 70% premium non-GMO protein, along with probiotics, amino acids, taurine, bovine colostrum, omega fatty acids, and more. Priced at just £41.99 (with free shipping), it's an affordable way to boost your dog's vitality. But why do these ingredients matter, especially for ageing dogs? Let's break it down.The Power of Protein: Combating Muscle Loss in Senior DogsProtein isn't just for bodybuilders – it's essential for our ageing canine friends. As dogs get older, their ability to synthesise protein diminishes, leading to sarcopenia (age-related muscle loss). This can result in weakness, reduced mobility, and a lower quality of life. Veterinary nutritionists recommend 28-30% protein on a dry matter basis for healthy senior dogs to combat this.
Higher protein intake helps maintain muscle mass, supports tissue repair, and even aids in weight management by keeping your dog feeling full longer.
In Jayfuel Hench Range, the 70% soy-free protein provides a rich source of essential amino acids, promoting lean muscle growth and repair. Whether your senior dog is struggling with stairs or just needs an energy boost for those UK park walks, this supplement can help preserve their strength and independence.
Studies show that senior dogs on higher-protein diets better maintain muscle protein stores, leading to improved overall health.

Probiotics: Boosting Gut Health and Immunity
A healthy gut is the foundation of wellbeing, and for ageing dogs, digestive issues like bloating, diarrhoea, or poor nutrient absorption can become common. Enter probiotics – live beneficial bacteria that restore balance in the gut microbiome. They help manage diarrhoea, reduce inflammation, and even support the immune system, which weakens with age.
For senior dogs, probiotics can improve digestion, enhance nutrient uptake, and lower the risk of chronic diseases.
Jayfuel includes 1.1 billion probiotic units, paired with a digestive enzyme complex, to optimise gut health. This means better absorption of all those vital nutrients, fewer tummy troubles, and a stronger defence against infections – perfect for UK winters when bugs are rife. Research indicates probiotics strengthen immune responses and promote healthier skin and coats too.
Senior pets with weakened immunity particularly benefit, making this a must-have for older dogs.
Amino Acids: The Building Blocks for Muscle and RecoveryAmino acids are the components of protein, and they're crucial for muscle health. In dogs, essentials like leucine, isoleucine, and lysine support protein synthesis, tissue repair, and energy production.
For ageing dogs, supplementing amino acids can speed recovery from exercise, reduce muscle soreness, and maintain metabolism.
They also aid in oxygen transport, brain function, and immune support.
Jayfuel's high-protein base delivers these amino acids in abundance, helping your senior dog build and repair muscles effectively. Whether recovering from surgery or just daily wear and tear, this supplement promotes stronger muscles and better vitality.
It's especially useful for active seniors who still love their hikes in the Lake District.

Spotlight on Other Key Ingredients in Jayfuel
Jayfuel doesn't stop at protein and probiotics – it's a comprehensive formula:
Taurine: This amino acid supports heart health, vision, and cognitive function, which are vital as dogs age. It helps maintain muscle strength, regulates nerve impulses, and may even suppress age-related issues like mitochondrial dysfunction.
Essential for preventing deficiencies that could lead to cardiomyopathy.
Bovine Colostrum: Packed with antibodies and growth factors, it boosts immunity, aids gut health, and supports muscle preservation
It enhances vaccine efficacy, reduces allergies, and promotes faster recovery.
Omega Fatty Acids: Including omega-3s, these reduce inflammation, support joint mobility, and improve brain health – ideal for arthritic seniors.
They also promote shiny coats and heart function.
Plus, B vitamins for energy, choline for brain support, and vitamins like E and biotin for skin health – all in one soy-free, steroid-free package.Not Just for Seniors:
