Supplements Without Magnesium Stearate: Why We Leave It Out (and You Might Want To)
If you’re looking at supplement labels more closely these days, you may have noticed an odd ingredient: magnesium stearate. It's one of the most common additives in the supplement industry — but it serves no purpose for your health.
So why is it used? And why are more people now choosing supplements without magnesium stearate?
Here’s what you need to know — and why you’ll never find it in any Arbor formula.
🧪 What Is Magnesium Stearate?
Magnesium stearate is a compound made from stearic acid (a saturated fat) and magnesium. It acts as a “flow agent” during manufacturing — meaning it helps powdered ingredients move smoothly through machines without sticking or clumping.
💊 Why It’s Used in Supplements
Manufacturers often include magnesium stearate to:
-
Speed up production
-
Prevent ingredients from clumping
-
Ensure capsules and tablets eject cleanly from machinery
-
Maintain a consistent appearance
It’s widely used in tablets, capsules, powders, and even some protein blends — but it offers no nutritional value and is not a source of magnesium.
⚠️ Why You Might Want to Avoid It
Magnesium stearate is generally recognised as safe in small amounts, but many health-conscious users choose to avoid it for good reasons:
1. It may interfere with nutrient absorption
Some studies suggest it can slow down the breakdown and absorption of active ingredients — especially if you’re already dealing with digestion issues or low stomach acid.
2. It adds nothing of value
It’s simply a processing aid. If a supplement can be made without it, why include it?
3. It’s often heavily processed
Stearic acid is commonly derived from cottonseed or palm oil — ingredients many people prefer to avoid due to environmental or allergen concerns.
4. Better alternatives exist
Brands who prioritise quality can create clean supplements without unnecessary additives — it just requires more care in formulation.
