Why Stack’s Micropill Coating (Methacrylate Polymer) is Safe and Effective

Stack’s micropills have a thin, protective layer made from a methacrylate polymer. This food-grade material has been safely used for decades to protect sensitive ingredients from stomach acid, ensuring nutrients are released at the right place, your intestine.

Why the Coating is Safe

• No Absorption into Bloodstream: The polymer molecules are large and water-loving, making them unable to cross the gut wall. They move through your digestive system and exit your body unchanged.

• No Endocrine Disruption: Reviewed independently by the U.S. FDA and the European Food Safety Authority, methacrylate polymer has been confirmed to have no hormone-like effects. It is classified as inert and non-absorbable.

• Minimal Chemical Residue: Each batch undergoes strict third-party testing, ensuring residual monomers are below 0.05%, far below international safety standards.

• No Known Allergies: Allergic reactions to methacrylates typically require direct, repeated skin exposure. Fully-polymerized material, as found in Stack, has no recorded cases of causing allergies through ingestion.

Regulatory Status

• USA: Listed as "Generally Recognized as Safe" (GRAS)
• EU: Approved as food additives (E1205/E1207)

Benefits of Stack’s Coating

• Protects Ingredients: Shields sensitive nutrients from harsh stomach acids.
• Optimizes Nutrient Absorption: Ensures nutrients are released where your body can best absorb them, enhancing their effectiveness.
• Timed Release: Allows precise layering of fast and slow-release nutrients.

Bottom Line

Think of Stack’s coating like grape skin, it protects the beneficial ingredients inside, remains undigested, and safely leaves your body. Trusted in medicines and supplements for over 40 years, each batch of Stack meets or exceeds global safety standards.
