If you’ve ever tried magnesium for Restless Legs Syndrome (RLS), you’ve probably noticed two things: 1. it can help — especially with night-time symptoms, and 2. not all supplements are created equal. Most people don’t realize that a lot of magnesium supplements contain bulking agents, fillers, and other unwanted additives that may interfere with absorption or trigger unwanted side effects. In this post, I’ll explain what to avoid — and share clean, trusted magnesium options I’ve personally researched or used.
🚫 What Are Bulking Agents?
Bulking agents (also called fillers or excipients) are ingredients added to pills and capsules to:
Make them easier to manufacture
Extend shelf life
Increase tablet size (without adding real nutritional value)
Common examples include:
Magnesium stearate
Microcrystalline cellulose
Silicon dioxide
Artificial colorings or sweeteners
These are technically "safe" but can irritate sensitive systems, especially if you're taking magnesium daily for something as persistent as RLS.
⚖️ Why Go Filler-Free?
Research suggests that cleaner supplements are often better absorbed and tolerated.
If your body is already stressed or sensitive — which is often the case with chronic issues like RLS — it's worth removing any friction you can.
Fewer additives = easier on digestion
Better bioavailability = your body can actually use it
Peace of mind = nothing hidden in the label
🧾 What to Look For:
Magnesium glycinate, citrate, or malate (gentle & well-absorbed)
No magnesium stearate
Third-party tested or hypoallergenic
Ideally from brands focused on purity, not mass-production
✅ Clean Magnesium Options (No Bulking Agents)
Here are a few options that meet these criteria — all available on Amazon.
1. Wild Nutrition Magnesium (Glycinate)
No fillers, clean ingredients, UK-based
Trusted by nutritionists. Great for sleep support and daily use.
2. Viridian High Potency Magnesium Citrate

🧘 Final Thoughts
Cutting out unnecessary ingredients might seem like a small detail — but for me, clean supplementation has made a difference. If you're already dealing with something as stubborn as RLS, you deserve supplements that actually support your body, not complicate things.
Let me know if you try any of these — or if you’ve found another clean magnesium option I should test!
