calcium Octanoate

Calcium Octanoate is a specialized form of calcium where the mineral is bound to octanoic acid (a medium-chain fatty acid found in coconut oil and breast milk). While traditional calcium supplements often use simple salts like carbonate or citrate, Calcium Octanoate offers a unique combination: the bone-strengthening power of calcium with the metabolic benefits of MCTs. It is designed to be gentle on the stomach and highly bioavailable, making it an excellent choice for those who experience digestive discomfort with other forms of calcium.

Health Benefits & Sources

Why You Need It

  • Gentle on Digestion: Unlike calcium carbonate, which can cause bloating and gas, this form is absorbed easily without requiring high levels of stomach acid.
  • Dual-Action Energy: It provides calcium for strong bones while the octanoic acid component serves as a rapid fuel source for the brain and body.
  • Bone Metabolism: Supports the structural integrity of the skeletal system, essential for preventing osteoporosis.

How It Works

Calcium Octanoate leverages the transport mechanism of medium-chain fatty acids (MCTs). Because octanoic acid is absorbed differently than long-chain fats, it bypasses the typical lymphatic route and goes straight to the liver. This potentially aids in the faster uptake of the calcium ion, supporting cellular energy production and mineralization of bones.

Natural Food Sources

It is important to note that Calcium Octanoate does not exist freely in nature in significant quantities; it is a synthetic compound created for supplements. However, you can find the two components separately in natural foods.

| Food | Amount | % DV | |---|---|---| |Dairy (Calcium) | 1 cup Milk | 30% | |Coconut Oil (Octanoic Acid) | 1 tbsp | High MCT | |Sardines (Calcium) | 3 oz | 33% | |Egg Yolks (Octanoic Acid) | 2 large | Trace MCT | |Collard Greens (Calcium) | 1 cup cooked | 25% |

Supplementation

Because this specific compound is not found in food, it is primarily used in dietary supplements. It is often chosen by individuals who have sensitive stomachs or malabsorption issues. Look for it in 'chelated' or 'MCT-bound' mineral blends.

Frequently Asked Questions

It is generally better absorbed and causes less bloating. Carbonate requires stomach acid to break down, whereas Octanoate is absorbed via fatty acid pathways, making it gentler.
No, the octanoic acid is chemically bound and tasteless. You won't get the flavor of coconut oil.
Yes. This supplement is dairy-free (unless fillers are added). It is a great alternative for those who cannot drink milk to get their calcium.
MCTs are known for supporting cognitive function and energy. Combining them with calcium creates a supplement that supports both the structural system (bones) and the metabolic system (energy).

Safety & Side Effects

Safety Profile

Calcium Octanoate is generally considered safe for most adults. The octanoic acid component is a natural constituent of many foods.

Who should avoid it?

  • Hypercalcemia: Individuals with high blood calcium levels should not supplement calcium in any form.
  • Kidney Issues: Those with a history of kidney stones should consult a doctor, as excess calcium can contribute to stone formation.
  • Interactions: Calcium can interfere with the absorption of certain antibiotics (like tetracyclines) and bisphosphonates. Take these at least 2 hours apart.

Note: The FDA considers octanoic acid (caprylic acid) Generally Recognized As Safe (GRAS) for consumption.
