Standalone Excipient · Filler / Flow

Dicalcium
Phosphate

A dense, free-flowing filler for formulations that need weight and flow. Often blended with MCC to balance compressibility against flow rate through the hopper.

Why This Excipient

Built for
your own blend.

01

Dense, Free-Flowing Filler

Higher bulk density than MCC, which helps formulations reach target tablet weight without an oversized tablet.

02

Balances MCC's Compressibility

Blending DCP with MCC trades a bit of binding strength for better flow — the two are commonly used together rather than as alternatives.

03

A Calcium Source

Contributes calcium and phosphate content, which is sometimes a relevant selling point on its own for nutraceutical and supplement formulations.

Questions

Frequently
asked.

What is dicalcium phosphate used for in tablets?

As a filler and flow agent in direct-compression formulations — it's denser and flows more freely than MCC, so it's typically blended alongside it rather than used as a full replacement.

How much dicalcium phosphate should I use?

20–35% of the excipient blend is a typical starting range, balanced against MCC for the rest of the filler system. See our guide on building a direct-compression blend from scratch.

Does dicalcium phosphate replace MCC?

No — they're complementary. MCC contributes most of the binding strength, DCP contributes flow and bulk density; most custom formulations use both.

4.7 out of 5, based on 3 reviews.

★★★★★
Kevin L. March 2026

Noticeably better flow than straight MCC blends we tried before. Hopper doesn't bridge anymore.

★★★★★
Sophia R. January 2026

Good bulk density for our calcium-forward formulation. Consistent between bags.

★★★★☆
Derek N. December 2025

Does what we need for flow, though we still had to dial in the ratio with MCC ourselves.
