7 Days to Comrades. Here's What to Know About Your Supplement Stack.
The questions are coming in thick and fast this week. Comrades is 7 days away and everyone wants to know about the supplements. Let me break it down properly.
VITADURANCE JOINT ACTIVE — Your Daily Foundation
Joint Active is built around ESM® — eggshell membrane from free-range farms in Navarre, Spain. It is one of the most complete natural joint support matrices available: native collagen types I, V, and X (not hydrolysed — preserved as it exists in nature), elastin, hyaluronic acid, chondroitin sulphate, and glucosamine sulphate. All in one capsule, from one source.
There is also a herbal anti-inflammatory component and vitamin K, which plays an important and often overlooked role in cartilage health and bone matrix regulation.
The dose question is the one I get asked most right now.
One capsule daily is your baseline. It is sufficient. In clinical studies, the ESM® therapeutic dose is 500mg/day and the preventive dose is 300mg/day — Joint Active is formulated at the therapeutic dose. More is not better here. The ingredient works cumulatively, not acutely — you are building and maintaining tissue matrix over time, not flooding your system with more than it can use.
For a short pre-event period you can go to one twice daily if you feel you need the extra support — joints under Comrades load are joints under serious stress. But this is not a permanent protocol and it is not necessary for everyone. One daily, consistently, is what the evidence supports as a baseline.
VITADURANCE PEA 500mg — Upstream Inflammation Management
PEA — palmitoylethanolamide — is one of the most interesting ingredients in the range, and probably the least understood. Here is what you need to know.
PEA is endogenous. Your body makes it. It is a fatty acid amide that your cells produce as an on-demand response to tissue stress, pain, and inflammation — it acts as a natural brake on the inflammatory cascade, working upstream through the endocannabinoid system and mast cell pathways to calm the response before it amplifies. Because it is something your body already produces and recognises, it has an excellent safety profile — no significant effects on kidney or liver function, no accumulation issues, no dependency.
The flip side of being endogenous: your body also breaks it down quickly. Half-life is short. This is why the dosing approach is different from Joint Active.
PEA is not a twice-daily fixed-dose supplement in the way Joint Active is. It is better understood as an as-needed anti-inflammatory tool. For ongoing chronic joint or nerve discomfort, a consistent daily dose builds a baseline. But for acute situations — race day, for example — you can take one every 3 hours as needed. That is what I do on race day.
I take PEA with me on the race. It helps manage the inflammatory load during the event — calming the upstream cascade while the body is under sustained mechanical and metabolic stress. Given the safety profile, there is no concern about taking it during a long-distance event. It is not a pain masker in the NSAID sense — it is not blocking your body's ability to signal real damage. It is simply supporting the natural brake mechanism your body already uses.
The full Comrades supplement picture:
🟢 Joint Active — 1 daily (baseline) or 1 twice daily short-term for extra support. Multi-source collagen + herbal + vitamin K. Take consistently.
🟢 PEA 500mg — daily for baseline inflammation management. On race day: 1 every 3 hours as needed. Goes in the race bag.
🟢 Cramp Spray — magnesium glycerophosphate + fulvic acid + dextrose. For acute cramping and electrolyte support during the race.
🟢 Alkaline Capsules — potassium-based buffer. Start in preparation days. Supports acid-base balance under prolonged exercise load.
To everyone running on Sunday — you've put in the training. This is the final week of managing your body well. Respect the taper, keep the nutrition clean, and trust the preparation.
See you on the other side. 💚
