The Link between Hormones, Aging, and Joint & Muscle Pain

Are you in your early 40s to 50s and suddenly experiencing unrelenting muscle and joint pain? Hormones may be why.

Joint & Muscle Pain Caused by Fluctuating and Dropping Hormone Levels

A number of my clients in pre-menopause, perimenopause and menopause notice gradually increasing physical pain and discomfort. They haven’t suddenly become less active. They’re still caring for themselves. Stretching, exercising, eating well. And yet, some time in their forties or fifties, a lot shifts - and quickly. Pains that are different from anything they’ve known before — a deep ache at the outer hip that won’t resolve, persistent neck tension, a shoulder that slowly freezes, a rotator cuff injury that seems to come out of nowhere, or muscles that tighten and refuse to soften no matter how much bodywork they receive.

The changes are too notable, too sudden, too persistent to simply be “aging.” And, in fact, it's not just aging - these changes are actually a profound biological transition in connective tissue driven by hormonal shifts during perimenopause and menopause.

The Role of Estrogen in Joint & Muscle Pain

Estrogen plays a central role in maintaining collagen, the structural protein that forms tendons, ligaments, fascia, cartilage, and even the supportive matrix of muscle. As estrogen levels decline, collagen production slows and tissue elasticity decreases. Tendons become stiffer and less resilient, micro-tears accumulate more easily, and healing capacity drops. This helps explain why conditions such as gluteal tendinopathy, frozen shoulder, rotator cuff injury, and chronic myofascial neck pain become dramatically more common in midlife females. Research shows that measurable declines in tendon collagen content can occur within just a few years of perimenopause. And many of us don't realize we are in perimenopause because we are looking for signs like irregular periods, hot flashes, night sweats, mood changes, declining libido, etc. Very few of us consider that unrelenting neck and shoulder tension may be one of the earlier signs.

As collagen production slows, the body also shifts toward a more inflammatory state. Estrogen normally acts as a powerful anti-inflammatory regulator, helping to quiet cytokines that drive tissue irritation. When levels fall, inflammatory signaling rises. This not only slows healing; it can also heighten pain sensitivity, making sensations feel sharper and more persistent.

Testosterone in Women also Drops during Perimenopause & Menopause

Muscle physiology also changes. Testosterone, growth hormone, and other anabolic signals gradually decline with age, reducing muscle protein synthesis and recovery capacity. As muscle strength decreases, tendons are asked to absorb more mechanical load. Over time, this imbalance contributes to degeneration and chronic pain patterns.

The Role of the Gut Microbiome and Joint & Muscle Pain

One of the most fascinating areas of recent research is the connection between the gut microbiome and hormone regulation. Certain gut bacteria help metabolize and recycle estrogen through what researchers call the “estrobolome.” When microbiome balance is disrupted, estrogen metabolism can shift in ways that further increases inflammation and impair tissue repair. Some strains also increase histamine production, which can further aggravate pain pathways and connective tissue irritation. Among the most studied probiotic strains is Lactobacillus gasseri, which has been shown in clinical research to reduce inflammatory markers, support metabolic health, strengthen gut barrier function, and positively influence estrogen balance. A healthy microbiome does far more than support digestion; it plays an active role in hormonal regulation and tissue healing. I'm not suggesting that you run out and buy loads of L. Gasseri, but researching what might work best for your particular body is a good start.

Thankfully, there are meaningful ways to support the body through these changes.

Treat, Heal and Reverse Muscle & Joint Pain

Physical therapy remains one of the most evidence-supported treatments for tendinopathy, particularly approaches that use progressive loading rather than rest alone. Controlled strengthening stimulates collagen remodeling and helps restore tendon resilience. Gentle but consistent resistance training, postural retraining, and stabilization work around the shoulder girdle and hips can significantly reduce pain and improve function.

Hormonal support can also be transformative when appropriately prescribed. Bioidentical hormone therapy has been shown to improve collagen synthesis, enhance tendon elasticity, and reduce joint pain in many women. Estrogen supports connective tissue structure and reduces inflammation. Progesterone contributes to tissue repair signaling and helps regulate the nervous system, supporting restorative sleep that is essential for healing. Testosterone plays a critical role in maintaining muscle mass, strength, and load tolerance around joints.

Nutrition profoundly influences connective tissue health. Adequate protein intake is especially important, yet many midlife women unknowingly consume far less than their bodies require for repair. Nutrients that support collagen synthesis — including vitamin C, zinc, glycine, and omega-3 fatty acids — can help reduce inflammation and improve healing capacity. Some women also find that lowering dietary histamine load reduces pain flares, particularly when chronic inflammation is present. I know I do!

While a low-histamine diet is recommended in particular cases, many can benefit from a low-inflammation (anti-inflammatory) diet, which focuses on whole, nutrient-dense foods that reduce chronic inflammation. Key staples include leafy greens, fatty fish (salmon), a small portion of healthy nuts & seeds, colorful fruits (in moderation, fruit = sugar), and olive oil. A low inflammatory approach restricts processed foods, refined sugars, and saturated fats, which are known to trigger inflammatory responses.

Certain supplements also come generally recommended at this phase of life - and, always consult with a professional. Collagen peptides taken alongside vitamin C have been shown to improve markers of tendon repair. Omega-3 fatty acids help quiet inflammatory cytokines. Magnesium supports muscle relaxation and neuromuscular recovery. Curcumin demonstrates measurable anti-inflammatory effects in tendon tissue, and creatine monohydrate has been shown in studies to improve muscle strength and recovery in aging women. These are not medical recommendations. If you choose to try one or more of these, always consult your practitioner and start low and slow - one supplement at a time. Our bodies are miraculous magical machines - when we start tinkering, it'll work hard to recalibrate a new equilibrium - and sometimes the effect is not desirable.

Restoring microbiome health remains a foundational piece of the puzzle. Diverse fiber intake, targeted probiotics, polyphenol-rich plant foods, and minimizing unnecessary antibiotic exposure all contribute to a gut environment that supports hormonal balance and lowers systemic inflammation.

Acupuncture can be especially supportive for tendon, muscle, and joint pain arising during perimenopause and menopause because it works with the very mechanisms that are shifting during this stage of life. Research shows acupuncture helps regulate inflammatory cytokines, improve local blood flow to poorly vascularized tissues like tendons, and stimulate fibroblast activity involved in collagen repair — all of which are critical when declining estrogen is slowing connective tissue healing. It also modulates the nervous system, reducing pain sensitization that often increases as hormonal buffering decreases. Acupuncture supports parasympathetic regulation that promotes tissue recovery and restorative sleep. From an endocrine perspective, studies suggest acupuncture can influence hypothalamic-pituitary-ovarian signaling, helping stabilize hormone fluctuations and reduce symptoms such as hot flashes, stress reactivity, and cortisol dysregulation that further impair tissue repair. Clinically, this often translates to reduced pain, improved mobility, and a gradual restoration of resilience in muscles, tendons, and joints that have become more vulnerable.

Another modality gaining attention is red and near-infrared light therapy, also known as photobiomodulation. Research suggests this therapy can enhance mitochondrial energy production within cells, stimulate collagen synthesis, reduce inflammatory signaling, and accelerate tissue repair. Clinical trials show promising results for tendon healing and pain reduction when used consistently over time.

Perhaps most importantly, it helps to understand that midlife musculoskeletal pain is not a terminal sentence. It is often the body responding to a complex hormonal and metabolic transition. When these underlying physiological shifts are recognized and supported, healing becomes not only possible, but transformative.

Again and again, I see women regain strength, mobility, and a renewed sense of trust in their bodies once these root causes are addressed. When we understand the biological “why” behind these changes, we can finally begin to care for the body in the way that it actually needs.

I'm not a doctor and suggest that you chat with your treating physician to determine your best course of action and treatment. I general, it's helpful to eat whole foods that are nutrient dense and high in fiber, protein and iron whenever possible. And, The following supplements appear to have the strongest research support for perimenopausal, menopausal, and post-menopausal women experiencing joint, tendon, and muscle pain. The primary mechanisms of benefit include reducing systemic inflammation, supporting collagen synthesis, improving muscle function, and addressing common nutrient deficiencies associated with hormonal transition. If you choose to try one or some of the supplements listed below, start low and slow, and begin with only one at a time.

Omega-3 fatty acids (EPA/DHA):Well-established anti-inflammatory effects through down-regulation of pro-inflammatory cytokines and prostaglandins. Clinical studies demonstrate reductions in joint pain and stiffness in postmenopausal populations. Krill oil and algae-based (vegan) omega-3 supplements are considered equally effective as salmon-derived fish oil for raising EPA and DHA levels — the two fatty acids responsible for anti-inflammatory and musculoskeletal benefits.

Hydrolyzed collagen peptides (with vitamin C):Provide glycine, proline, and hydroxyproline required for connective tissue repair. Research shows improved tendon integrity, joint comfort, and cartilage support with consistent use.

Curcumin (bioavailable forms):The classic anti-inflammatory supplement. Randomized trials show clinically meaningful reductions in musculoskeletal pain.

Magnesium (glycinate, citrate, or threonate forms):Supports neuromuscular relaxation, mitochondrial function, and inflammatory regulation. Deficiency is common in midlife and associated with muscle tension and chronic pain.

Vitamin D:Critical for musculoskeletal health, immune modulation, and muscle strength. Low serum levels correlate strongly with increased joint pain and reduced functional capacity.

Creatine monohydrate (emerging evidence):Supports muscle mass preservation, strength, and recovery in aging women, indirectly reducing tendon load and injury risk.

MSM (methylsulfonylmethane):Shows anti-inflammatory and analgesic effects in clinical trials, with potential benefits for joint comfort and connective tissue resilience.

While research of the gut microbiome is still fairly green (there is SO much we do not know), specific strains of the Probiotic L. gasseri (as well as other probiotics) are worth an honorable mention because they can support estrogen metabolism, reduce systemic inflammation and oxidative stress, as well as improve gut barrier integrity and immune signaling.

Another honorable mention: B vitamins and iron play important supportive roles in musculoskeletal health, especially during midlife. B vitamins — particularly B6, B12, and folate — are essential for nerve function, energy production, and reducing homocysteine, a compound linked to increased inflammation and connective tissue breakdown. Iron is critical for oxygen delivery to muscles and tissues; low iron can contribute to fatigue, muscle soreness, poor recovery, and increased pain sensitivity. While neither directly repairs tendons, deficiencies in either can significantly worsen muscle tension, healing capacity, and overall resilience.
