Supporting Joint Health Naturally with Joint Support

Joint health is fundamental to maintaining mobility, independence, and overall wellbeing at all life stages. Whether working with ageing clients, active individuals, or those experiencing early discomfort, understanding joint health is essential. Over time, wear and tear, repetitive movement, and reduced connective tissue resilience can lead to stiffness, reduced flexibility, and discomfort. With over 10 million people in the UK living with arthritis, this is one of the most common conditions a practitioner will encounter (Jordan, 2010). Symptoms such as pain, fatigue, and reduced mobility can lead to disability, mental strain, financial burden, and reduced independence, impacting work and social life. (NICE, 2022)

In this practitioner deep-dive, Nutritional Therapist Olivia explores the structure of joints and how targeted nutrients can support joint health. She also introduces the new Joint Support, outlining its key ingredients, benefits, and practical applications.

Understanding joint structure

Joints consist of three main components: articular cartilage, synovial fluid, and ligaments. A joint is where two bones meet to allow smooth movement. Bone ends are covered in cartilage to reduce friction, while synovial fluid within the joint cavity provides lubrication. The joint is enclosed by a capsule lined with a synovial membrane that produces this fluid, while ligaments reinforce and stabilise the joint.

Cartilage: Made up of chondrocytes, which produce an extracellular matrix (ECM) composed primarily of type II collagen, alongside proteoglycans, elastin, and glycoproteins. This structure provides a smooth, shock-absorbing surface for movement. Cartilage is avascular, lacking blood vessels and nerves, making repair slow. (Sophia, 2009) Type II collagen (90 – 95% of cartilage collagen) forms a triple helix that stabilises the matrix and maintains structural integrity.

Synovial fluid: Due to cartilage’s limited blood supply, it relies on synovial fluid to deliver nutrients through diffusion as fluid moves in and out of cartilage during movement, supplying oxygen and nutrients while maintaining lubrication. This process supports joint function but also limits efficient repair.

Ligaments: Dense connective tissues that connect bones, providing stability while allowing controlled movement. Rich in type I collagen, with elastin, proteoglycans and minerals contributing to strength and elasticity. Key glycosaminoglycans include chondroitin and dermatan sulphate, supporting structure and resilience.

What happens as joints age

Ageing reduces collagen production, weakening cartilage, while declining synovial fluid reduces lubrication. Together, these changes increase friction, stiffness, and discomfort.

Lifestyle significantly influences joint health. Regular exercise maintains flexibility and muscle support, whereas inactivity increases stiffness. Excess weight places greater strain on joints, particularly in the knees and hips. Diet also plays a role with processed foods promoting inflammation, while nutrient-dense anti-inflammatory diets support joint function. Pro-inflammatory cytokines such as IL-1β and TNF-α contribute to cartilage and ECM degradation, reinforcing the importance of reducing inflammation, supporting the matrix, and promoting chondrocyte regeneration. (Sanchez-Lopez, 2022)

Targeted nutrition can therefore play a key role by supporting collagen production, lubrication, and inflammation balance, complementing a healthy lifestyle to maintain joint comfort and mobility.

Key nutrients for joint support

Given the complexity of joint structures, effective support should be multi-faceted, targeting several pathways:

• Structural support: nutrients that aid regeneration and maintenance of cartilage and synovial fluid
• Lubrication: supporting optimal viscosity and function of synovial fluid to reduce friction
• Inflammation and oxidative stress reduction: limiting tissue degradation and supporting mobility

Our Joint Support formula is designed to address these key areas through a comprehensive blend of ingredients.

Ingredient Spotlight

Glucosamine HCl

Glucosamine is a glycosaminoglycan, a specific structure made up by both protein (amino acids) and carbohydrates. This structure allows for flexible branched chain molecules, meaning they are perfectly designed shock absorbers within joints. They make up cartilage and form part of synovial fluid, and the degradation of these tissues is associated with joint pain, particularly osteoarthritis (OA). Glucosamine supplements come in two forms, sulphate or hydrochloride (HCl), and while most studies use the sulphate form, glucosamine hydrochloride is increasingly shown to be as effective, particularly in improving pain. Generally, the hydrochloride form is preferred as it is purer and more tolerated (especially to people with sulphur sensitivities). (Nakamura, 2007)

Glucosamine has been shown to be chondroprotective in OA by inhibiting the degeneration of type II collagen while at the same time also supporting its synthesis. (Nagaoka, 2019)

Glucosamine can repair ligament, tendon or cartilage tissue. It can also reduce the destruction of cartilage caused by taking NSAIDs. (Kwoh, 2018) Meta-analysis shows that glucosamine supplementation was associated with reduced pain scores and improved quality of life after supplementation. (Ogata, 2018)

Another meta-analysis study demonstrated significant improvements in pain reduction, joint narrowing, and joint function with glucosamine compared to placebo. It also appears to reduce inflammation and inhibits collagen degradation. (Veronese, 2020)

Collagen (types I & II)

Collagen is the primary structural protein in connective tissue, accounting for 25–35% of total body protein. It is synthesised within the ECM by fibroblasts, osteoblasts, and endothelial cells, where it provides tensile strength and structural integrity. Approximately 16 collagen types exist, but 80–90% is made up of types I, II, and III, which can cross-link with each other and interact with proteoglycans to form resilient, functional tissues. (Lodish, 2000)

Each collagen type has a distinct structure based on its amino acid sequence and folding pattern. Collagen peptides are characterised by repeating sequences where every third amino acid is glycine, commonly alongside proline and hydroxyproline. These amino acids enable the formation of a triple-helix structure, which undergoes enzymatic modifications (including hydroxylation and glycosylation) before being assembled into collagen fibrils in the ECM. This hierarchical structure underpins collagen’s strength and flexibility.

• Type I collagen is the most abundant form, found primarily in bones, tendons, and ligaments, where it provides tensile strength and structural support.
• Type II collagen is the predominant collagen in cartilage, where it forms a fibrillar network that stabilises the ECM and resists compressive forces.

Collagen Type I [AE1.1]

Type I collagen is the most abundant form of collagen in the body, being found in bones, tendons, and ligaments. Its key functions are to support the structural strength of these tissues and to also aid their repair. Its significance becomes more important with age as collagen production declines as we get older. Marine Collagen is a source of type I collagen, suitable for skin, bones, ligaments and tendons. It has also been shown to increase type II collagen for joints. Its structure closely resembles human collagen and, in a hydrolysed peptide form, is easily absorbed through the gastrointestinal wall.

Type I collagen is particularly useful where there are tendon and ligament issues alongside joint issues to help with their structure and integrity so they can effectively stabilise the joint.

Collagen Type II

Type II collagen works synergistically with type I collagen to provide comprehensive support across both hard (bone) and soft (cartilage, ligaments) joint tissues. Degradation products of this type of collagen found in urine correlates with progression of cartilage damage in osteoarthritis. Hydrolysed type II collagen has been shown to support joint health primarily by providing amino acids that contribute to cartilage matrix synthesis and may stimulate chondrocyte activity. (Carillo-Norte, 2024) Meta analyses of randomised controlled trials report small to moderate improvements in pain and function compared with placebo.. (Ravindran, 2026)

Hyaluronic Acid

Hyaluronic acid is a non-sulphated GAG found in synovial fluid, where it plays a critical role in lubrication and smooth joint movement. It forms the backbone for proteoglycan aggregates such as aggrecan, which help cartilage retain water and maintain elasticity.

Its hydrophilic nature supports connective tissue hydration and resilience, contributing to reduced stiffness and improved comfort. Supplementation has been shown to improve symptoms of osteoarthritis. Given cartilage’s limited blood supply and slow turnover, maintaining synovial fluid quality is essential for nutrient delivery and joint function. (Sophia, 2009)

Boswellia Extract

Boswellia is an Ayurvedic herb that has traditionally been used for its anti-inflammatory properties and can benefit conditions including osteoarthritis (OA). It can inhibit 5-lipoxygenase pathways, in turn down-regulating inflammation in diseases associated with the production of leukotrienes. It can also reduce the production of inflammatory cytokines including IL-1B, IL-6, IFNy and TNFa, which are directly associated with cartilage destruction in OA. (Pilkington, 2022) It is also thought to prevent the degradation of GAGs and improve blood supply to joint tissue. These protective effects can also be associated with its antioxidant activity and suppression of ROS, lipid peroxidation and reduction of oxidative DNA damage. Meta-analysis demonstrates Boswellia supplementation can prevent articular cartilage degradation, decrease osteophyte formation, and improve physical mobilisation by reducing pain in OA patients. (Yu, 2020)

MSM

MSM (methylsulfonylmethane) is a source of sulphur crucial for maintaining healthy connective tissue, supporting both tissue building and pain regulation. It demonstrates anti-inflammatory, chemoprotective, and free radical–scavenging activity, with clinical evidence showing improvements in pain and physical function over short interventions . (Kim, 2006) When combined with glucosamine, MSM shows superior efficacy in reducing pain, swelling, and improving function compared to either alone.

Its anti-inflammatory effects are largely linked to downregulation of NF-κB, leading to reduced activation of downstream pathways, including r[AE2.1]educed expression of the NLRP3 inflammasome via inhibition of mitochondrial ROS signalling and downregulation of pro-inflammatory cytokines IL-1, IL-6, and TNF-α. (Butawan, 2017)[AE3.1]

MSM also plays a direct role in maintaining cartilage, with research indicating reduced cartilage surface degeneration. In addition, it exhibits antioxidant capacity; human studies show MSM pre-treatment before endurance exercise reduces markers of oxidative stress (including protein oxidation, lipid peroxidation, and creatine kinase) while increasing total antioxidant capacity. (Butawan, 2017)

Conclusion

Joint health is influenced by a complex interplay of structural integrity, lubrication, inflammation, and lifestyle factors. As we age, natural declines in collagen production and synovial fluid can compromise joint resilience, while inflammatory processes further accelerate tissue degradation. Given the high prevalence of joint-related conditions such as osteoarthritis, practitioners are increasingly required to take a proactive, multi-dimensional approach to support their clients effectively.

Targeted nutritional strategies offer a valuable opportunity to address these underlying mechanisms. By supporting collagen synthesis, maintaining cartilage structure, enhancing synovial fluid function, and modulating inflammation and oxidative stress, specific nutrients can help preserve joint comfort, mobility, and long-term function. Importantly, these interventions work best when combined with lifestyle foundations. Our new Joint Support brings together key evidence-based ingredients to deliver a comprehensive approach to joint care.

For practitioners, this provides a practical, science-led tool to support clients at various stages of joint decline, helping to improve both quality of life and functional outcomes.
