Daily Supplements for Neuromusculoskeletal Health: Brain, Body & Joint Support

The science, the mechanisms and the PubMed-backed rationale behind what I take.

Welcome back to MoveMed!

People often ask me what supplements I take myself and why. My answer is always the same. Supplements are not the foundation. The foundation is still LENDS - Love, Exercise, Newness, Diet and Sleep and NRE, (extras being sunlight, stress management and consistency). But when the basics are in place, certain supplements can help support the internal environment that the nervous system, muscles, joints, connective tissues and immune system rely on. That is how I think about them clinically. They are not magic. They are support inputs.

This is a breakdown of the supplements I currently take, the doses I use, what they may be helpful for, how they work and the key research papers behind them. I have kept this educational and evidence-led. In a few areas the evidence is strong. In a few areas it is more supportive than definitive. That distinction matters if you want to speak honestly and still position yourself as a clinician.

I’ve created an Amazon storefront with all of the supplements I personally use, including the exact brands I trust and purchase myself. This is simply to make things easier for you - no guesswork, just a curated list based on what I use in my own routine and recommend when appropriate.

First, the framework

When I look at supplementation through a movement and pain lens, I am usually asking four questions. Does it support tissue quality. Does it support energy production. Does it support nerve function or signal quality. Does it help regulate inflammation or recovery. That is a much more useful framework than simply calling something “good for joints” or “good for immunity.” Vitamin D, for example, is relevant to bone mineralisation and neuromuscular function. Creatine is relevant to ATP regeneration and muscle output. Omega-3s are relevant to inflammatory signalling and membrane function. B12 is relevant to myelination and nerve health. Different supplements support different layers of the same system.

The second point is that not every supplement has equally strong evidence for every claim people make online. Some are better supported for a deficiency state than as a blanket recommendation. Some help more with symptoms than structure. Some have excellent mechanistic plausibility but more modest clinical trial data. That is why I prefer to say this is my personal stack and my educational reasoning, not a prescription for every person.

Creatine - aiming for 10 to 20 g per day

Creatine is probably the one supplement I feel the most. I’ve been taking it consistently for a few years now and especially since having a baby and dealing with broken sleep, I notice a real difference in my energy and recovery. I still train regularly, and it just feels like I have a bit more in the tank. Whether that’s from improved ATP availability or just overall system support, it’s one of the few supplements where I genuinely notice a performance and recovery benefit day to day.

Creatine is one of the most evidence-based supplements in the entire performance and rehabilitation world. It increases phosphocreatine availability, which helps regenerate ATP quickly during high-demand activity. In practice that means better support for strength, repeated effort, training quality and often lean mass gains when paired with resistance training. There is also growing interest in creatine for brain energy metabolism and neuro “protection”, although the strongest consistent evidence still sits with muscle performance and body composition.

For the musculoskeletal side, I would point to PMID: 34199420, which found that creatine supplementation combined with resistance training augments gains in lean tissue mass and strength in ageing adults and PMID: 39519498, which found enhanced upper- and lower-body strength in adults under 50 when creatine was combined with resistance training. This is one of the clearest examples of a supplement that improves output, not just theoretical physiology.

The only caveat is dose framing. Standard maintenance dosing is usually described as 3 to 5 g/day, while 20 g/day is more typical of a short loading phase before transitioning to maintenance. So if you are taking 10 to 20 g/day, that is worth explaining as your personal protocol rather than implying it is the standard long-term maintenance dose for everyone. Larger doses can also increase the chance of gastrointestinal upset, especially if taken in one hit.

Omega-3s - at least 2000 mg EPA per day

Omega-3s are a non-negotiable for me. From a clinical perspective I understand the inflammatory pathways, but practically, it just feels like things move better when I’m consistent with them. Almost like things are less “stiff” or irritated. I often joke that it feels like it’s lubricating the joints, even though we know it’s working through inflammation and cell membrane function. It’s one of the simplest ways I support recovery and overall joint comfort.

Omega-3s, especially EPA and DHA, are powerful because they influence the membrane and inflammatory environment in which the nervous system and musculoskeletal system operate. They alter eicosanoid production, influence specialised pro-resolving mediators and can shift inflammatory signalling away from a more pro-inflammatory profile. Clinically, that is why they are often discussed in relation to joint pain, recovery and broader cardio, metabolic and brain health.

For osteoarthritis-type pain and joint function, a very useful current paper is PMID: 37226250. This meta-analysis concluded that omega-3 supplementation was effective for relieving pain and improving joint function in people with osteoarthritis. For inflammatory pain more broadly, an older but still influential meta-analysis, PMID: 17335973, found that omega-3 polyunsaturated fatty acids were an attractive adjunctive treatment for joint pain associated with inflammatory conditions. In simple terms, this is one of the better supplements for improving the inflammatory climate around movement and recovery.

Magnesium citrate - 400 mg at night

Magnesium is something I take in the evenings, and for me it’s very much about winding the system down. I notice better sleep quality and just a general sense of relaxation. Whether that’s through its effect on the nervous system or muscle tone, it helps me switch off. It’s less about performance in the gym and more about recovery, sleep, and giving the system the best chance to reset overnight.

Magnesium matters because neuromuscular tissues are electrically active tissues. Magnesium is involved in ATP handling, ion channel behaviour, membrane stability and muscular contraction-relaxation dynamics. That is why magnesium deficiency can show up as irritability in the system, tension, cramps, fatigue and poorer recovery. It also has plausible relevance to sleep and nervous system regulation, which is one reason many people prefer taking it later in the day.

The most robust paper to mention here is PMID: 32956536, a Cochrane review on magnesium for skeletal muscle cramps. It is useful because it keeps you honest. It found that magnesium is unlikely to provide a clinically meaningful cramp-prevention effect for idiopathic cramps in older adults. That does not make magnesium useless. It simply means the common online claim that magnesium is a guaranteed “cramp fix” is too simplistic. A more accurate position is that magnesium is foundational for neuromuscular physiology, may help some individuals more than others and may be most useful where intake is low or where recovery, soreness, sleep, or muscle function are relevant. There is also more recent review-level evidence suggesting benefits for muscle soreness, recovery and aspects of muscle health.

Vitamin D3 - 4000 IU per day *

Vitamin D is one I’ve tracked properly with blood tests. The dose I take keeps me within a healthy range, which is the key point here. It’s not about taking high doses randomly, it’s about correcting a deficiency if present and then maintaining optimal levels. Especially living in the UK with limited sunlight, it’s something I take seriously from a long-term health and musculoskeletal perspective.

Vitamin D is not just a vitamin. It behaves more like a hormone precursor and has wide biological reach. It promotes calcium absorption, supports bone mineralisation and also has recognised roles in neuromuscular and immune function. That is why low vitamin D status can matter in people with bone health issues, low sunlight exposure, reduced muscle performance or higher-risk profiles for deficiency.

The key reality check paper is PMID: 30293909. This large systematic review concluded that vitamin D supplementation does not prevent fractures or falls and does not have clinically meaningful effects on bone mineral density in the general way it is often marketed. That is important. It means vitamin D should not be oversold as a universal musculoskeletal miracle. It is best framed as a nutrient that matters greatly when levels are low, when deficiency risk is real or when you are targeting bone biology and calcium handling more deliberately.

*A practical safety note matters here as well. 4000 IU per day is the adult tolerable upper intake level listed by the NIH Office of Dietary Supplements. That does not automatically make it unsafe, but it does mean this is a dose best used with some context, ideally with bloodwork such as serum 25-hydroxyvitamin D and an understanding of total intake from all sources.

Glucosamine, chondroitin & MSM

This is something I’ve been taking and recommending for years. Clinically, I’ve seen it help certain patients, especially with joint comfort, and personally I feel better on it. It’s not a quick fix, but over time it feels like it supports how my joints tolerate load, especially with regular training. It’s one of those long-term consistency supplements rather than something you “feel” overnight.

This is the classic joint-health combination. Glucosamine and chondroitin are usually positioned around cartilage matrix support, glycosaminoglycan biology and symptom support in osteoarthritis. They are not rebuilding an entire joint from scratch, but they may help support pain, stiffness and function in some people, especially in osteoarthritic presentations.

The anchor paper here is PMID: 29980200, an updated meta-analysis. It found that oral chondroitin was more effective than placebo for relieving pain and improving physical function, while glucosamine showed an effect on stiffness outcomes. A 2023 meta-analysis, PMID: 35024906, also supported the combination in knee osteoarthritis. So for public education, glucosamine and chondroitin are still very reasonable to discuss as symptom-support supplements for joint comfort and function.

MSM is the weaker part of the trio from an evidence standpoint. There are positive individual trials, including PMID: 17516722, which reported analgesic and anti-inflammatory effects in osteoarthritis, but MSM does not have the same depth of meta-analytic support as glucosamine and chondroitin. So if you want to be very precise online, say the product combines three ingredients commonly used for joint comfort, with the best overall evidence sitting with glucosamine and chondroitin and more modest evidence for MSM.

CoQ10 - 200 mg per day

CoQ10 is part of my daily stack mainly from an energy and cellular health perspective. It’s not as obvious in terms of a “felt” effect like creatine, but understanding its role in mitochondrial function, it makes sense to me as a long-term support supplement. I see it as investing in the system at a deeper level, especially with ongoing training and workload.

CoQ10 sits slightly differently from the others because I would position it more around cellular energy and oxidative stress management than around a direct joint-specific effect. Coenzyme Q10 is part of the mitochondrial electron transport chain, so it is relevant to ATP production. It also has antioxidant properties, which is why it is often discussed in the context of fatigue, exercise tolerance, cardiovascular health and mitochondrial resilience.

The most defensible paper here is PMID: 36091835, a meta-analysis showing CoQ10 was effective and safe for reducing fatigue symptoms. A newer 2025 systematic review and meta-analysis, PMID: 41457257, found that CoQ10 increases blood concentrations reliably but has limited and inconsistent effects on exercise performance. So the honest clinical summary is this: CoQ10 makes sense if you are thinking in terms of mitochondrial support, fatigue, and oxidative stress, but the evidence for direct musculoskeletal performance enhancement is not as strong or as consistent as it is for creatine.

Vitamin C - 1000 mg per day

Vitamin C is something I tend to lean into more when I’m feeling run down or under a bit more physical stress. Knowing its role in collagen production and recovery, I see it as supporting the tissues behind the scenes. It’s not something I necessarily “feel” immediately, but it’s part of supporting the environment for healing and resilience, especially during busier or more stressful periods.

Vitamin C earns its place in a musculoskeletal stack because it is directly involved in collagen synthesis. Collagen is not just about skin. It is fundamental to tendons, ligaments, fascia, cartilage matrix, and bone healing. Mechanistically, vitamin C functions as a cofactor for prolyl and lysyl hydroxylase enzymes, which stabilise the collagen triple helix and help form stronger connective tissue. It also contributes antioxidant support, which matters in tissue recovery and in managing oxidative stress around injury and repair.

The paper I would anchor this to is PMID: 30386805. That review concluded that vitamin C has potential to accelerate bone healing after fracture, increase type I collagen synthesis (yes the same collagen that everyone is speaking about) and reduce oxidative stress markers. For public education, I would frame vitamin C less as “immune support only” and more as “connective tissue support plus antioxidant support.” That is a much better fit for an MSK audience.

Vitamin B12

B12 is one I take more specifically for nerve health. Given its role in the nervous system, it fits well with how I think about movement, coordination, and overall function. It’s one of those nutrients where I’d rather be confident my levels are adequate, especially with how important the nervous system is in everything we do.

Vitamin B12 is one of the easiest vitamins to justify specifically for the nervous system. It is essential for myelin integrity, methylation, DNA synthesis, and normal neurological function. Low B12 status can contribute to neuropathy, fatigue, altered sensation, and impaired coordination. This is why B12 deserves to be considered separately from a generic B-complex.

Two excellent papers here are PMID: 32722436 and PMID: 36457818. The first is a systematic review of B12 as a treatment for peripheral neuropathic pain. The second is a meta-analysis showing B12 can improve neuropathic symptoms and reduce pain in diabetic neuropathy. So if you want a cleaner, stronger, more defensible “neurology supplement” story, B12 is much easier to support than a broad, non-specific B-complex claim.

Zinc *

Zinc is similar for me in that I’ll prioritise it more when I feel like my immune system needs support. If I’m travelling, run down, or just under more stress, I’ll bring it in more consistently. It’s one of those foundational nutrients that supports recovery and general system function rather than something you notice acutely.

Zinc is often framed as an immune supplement, but it also matters for tissue repair, protein synthesis, enzyme activity and cellular signalling. In a musculoskeletal setting that matters because healing is a cellular process. In an immune setting it matters because zinc is important for both innate and adaptive immune function.

The paper to reference is PMID: 33356467, a systematic review and meta-analysis on zinc supplementation and immune factors in adults. The deeper mechanistic review PMID: 29186856 is also useful because it explains zinc’s regulatory role in intracellular signalling pathways in the immune system. *So my practical line would be that zinc supports recovery biology and immune readiness, but it is not something to megadose casually.

That last point matters. The NIH lists the adult RDA for zinc at 11 mg/day for men and the adult upper limit at 40 mg/day. It also notes that doses of 50 mg or more for weeks can impair copper absorption, reduce immune function, and lower HDL cholesterol. So if someone is taking a zinc supplement alongside a multivitamin, total intake should be checked.

Vitamin B-complex

This is where nuance is important. B vitamins are deeply relevant to nervous system function, methylation, red blood cell biology, neurotransmitter production and energy metabolism. On paper that sounds ideal for a “brain and nerve” message and mechanistically that is true. But the clinical evidence is strongest when B-vitamin deficiency or insufficiency is part of the picture, especially in peripheral neuropathy contexts, rather than as a blanket claim that everybody needs high-dose B-complex supplementation.

A useful paper here is PMID: 33619867, a systematic review and meta-analysis looking at neuropathy, pain, and B-vitamin biomarkers. There is also PMID: 34990506, which suggested vitamin B supplementation could improve several symptoms and signs in diabetic peripheral neuropathy. So the most accurate public message is that B vitamins matter massively for nerve health and energy production but the best evidence is usually in deficiency-linked or neuropathy-linked settings rather than as a universal upgrade for everyone.

There is also an important safety point. The NIH fact sheet lists 100 mg/day as the US upper limit for vitamin B6 in adults, while EFSA’s 2023 opinion set a much lower adult upper limit of 12 mg/day based on peripheral neuropathy risk. If your B-complex is a “100” formula, it is worth checking exactly how much B6 it contains, especially if you are also taking a multivitamin. Chronic excess B6 can itself contribute to neuropathy, which is obviously the opposite of the intended goal.

The “Multivitamin”

I don’t take a multivitamin all year round. I tend to cycle it. I’ll take it for a few months when I want to tighten things up nutritionally, and then take a break. I see it more as a top-up or a reset rather than something I rely on daily. It’s a useful tool, but I still prioritise whole food and the basics first.

A multivitamin is best understood as nutritional insurance, not as a direct ergogenic supplement. A privileged extra if you can afford it. It may help cover micronutrient gaps, especially in people with imperfect diets, heavier workloads, frequent travel, intense training or simply real life. Many vitamins and minerals act as cofactors for enzymatic reactions involved in energy production, protein synthesis, immune function, red blood cell production, and tissue repair. That is the logic behind a multivitamin.

That said, the evidence for a generic multivitamin directly improving MSK outcomes is not especially strong. PMID: 16756533 is a systematic review of multivitamin and multimineral supplementation, and more recent work such as PMID: 32823974 suggests multivitamin use can improve vitamin C and zinc status and perceived health status, but not necessarily objective immune measures. So I would position a multivitamin carefully. It is there to support adequacy and baseline physiology, not to claim a specific dramatic joint or nerve benefit on its own.

Summary (Clinical)

The nervous system needs the right biochemical environment to produce better outputs. Muscles need the right fuel and minerals to contract and recover well. Connective tissues need the right substrates and cofactors to heal and tolerate load. Immunity and inflammation affect how threatened or resilient the whole system feels.

The strongest “performance and rehab” evidence in this stack is with creatine, followed by omega-3s for inflammatory pain contexts and then glucosamine-chondroitin for selected joint symptom support. Vitamin D is important, but most helpful when you actually need it. Magnesium is great to aid sleep. B12 is highly relevant for nerve health. CoQ10 and multivitamins make more sense as supportive physiology tools than as headline musculoskeletal supplements.
