Calgae marine calcium and protein supplement
Marine calcium & protein

Calgae

Natural calcium and protein from freshly harvested marine sources.

Calgae is an innovative synergistic combination of foods from the ocean's bounty. Red algae (maerl), sustainably harvested from the cool waters of the Icelandic coast, is rich in calcium, magnesium, and other minerals. Sustainable, hypoallergenic hydrolyzed fish protein completes the blend with essential amino acids that promote normal digestive health.

$32USD · ~80 teaspoons per jar
  • Low-phosphorus calcium source — ideal for high-protein or renal diets
  • Red algae (maerl) sustainably harvested from Iceland's cool waters
  • Hypoallergenic hydrolyzed fish protein with essential amino acids
  • 1000 mg calcium and 500 mg protein per teaspoon

Requires veterinarian approval — your vet's name is requested at checkout.

Sustainably harvested red algae (maerl) from the Icelandic coast, plus hypoallergenic hydrolyzed fish protein.

Each teaspoon contains approximately 1000 mg calcium and 500 mg protein.

Why Calgae instead of bone meal?

Bone meal is the traditional calcium source for home-prepared diets, and it works well for healthy adult dogs whose diets need both calcium and phosphorus. But not every diet needs more phosphorus.

Calgae is the right choice when the diet is already protein-dense (phosphorus comes along for the ride with protein), or when phosphorus must be restricted — kidney disease being the classic example. Each teaspoon delivers ~1000 mg calcium and ~500 mg protein with very little additional phosphorus.

The calcium comes from red algae (maerl), sustainably harvested off the Icelandic coast. Maerl naturally concentrates calcium, magnesium, and trace minerals from cold ocean water, and the harvest is managed for long-term ecological health.

Calgae's protein is hypoallergenic, hydrolyzed fish protein — pre-broken down into peptides and amino acids that promote normal digestive health and rarely trigger food sensitivities.

When to choose Calgae

  • · Renal / kidney diets where phosphorus must stay low
  • · High-protein and ketogenic diets that already supply phosphorus
  • · Cancer-support diets where preserving lean mass matters
  • · Pets sensitive to common animal proteins (Calgae's fish protein is hydrolyzed)

If your diet does need phosphorus, contact us or use bone meal instead. Always follow your veterinarian's specific recommendation for your pet.
