Complete Calcium Synergy - Calcium Plus

The Snail’s Apothecary

A complete mineral supplement for terrestrial invertebrates

Calcium Plus is an artisanal mineral blend designed to meet the needs of terrestrial invertebrates:
snails (including Achatinidae), isopods, millipedes, roaches, and other detritivorous or calciphile species.

Formulated and handcrafted in the Perche region, in the heart of Normandy (France 🇫🇷), this powder combines multiple natural sources of calcium to provide a balanced, bioavailable, and long-lasting mineral supply.

Composition

• Calcium carbonate
• Crushed oyster shell
• Micronized eggshell
• Lithothamnium (calcareous algae rich in trace elements)

A synergy designed for optimal absorption

Unlike single-source calcium supplements, our Complete Calcium Synergy combines:

✔ Fast-absorbing calcium
✔ Gradual, long-term release
✔ Magnesium and essential trace elements

Result: a complete mineral supply adapted to the biological cycles of invertebrates.

• Aids successful molting
• Helps prevent mineral deficiencies

Directions for use

• Provide freely in the terrarium
• Place in a dry dish or directly on the substrate
• Suitable for daily use

Must be combined with a varied diet for optimal balance.

Artisanal production – The Perche

Each batch is carefully prepared in the Perche region using an artisanal approach:

• carefully selected raw materials
• blended in small batches to order
• no additives, no preservatives

Small-scale production focused on quality over quantity.

Why choose Calcium Plus?

Because not all invertebrates absorb calcium in the same way.
This synergy is designed to provide more than just a mineral supplement: a balanced solution tailored to real-world needs.

Frequently Asked Questions about calcium for snails and invertebrates

What type of calcium should be given to snails (including Achatinidae)?

Snails require a constant supply of bioavailable calcium to maintain a strong shell.
A multi-source calcium blend like Complete Calcium Synergy provides gradual absorption, combining fast-acting and slow-release calcium, making it more effective than a single source.

Why does my snail have a fragile shell?

A fragile shell may be caused by:

• calcium deficiency
• poor absorption
• rapid growth
• dietary imbalance

Regular supplementation with a multi-source calcium helps strengthen and repair the shell.

Do isopods need calcium?

Yes. Isopods use calcium to:

• harden their exoskeleton
• successfully molt
• maintain overall health

Calcium is essential in a terrarium setup.

Why provide calcium to millipedes and roaches?

Millipedes and some roaches require calcium for:

• cuticle formation
• supporting molting cycles
• preventing deficiencies

A proper mineral supply improves vitality and reproduction.

How often should calcium be provided?

Calcium should be available at all times in the terrarium.
Invertebrates naturally regulate their intake according to their needs.

Can calcium be mixed with food?

Yes, but it is recommended to also provide calcium separately, allowing the animals to regulate their intake naturally.
