Calcium oyster shell is a natural source of calcium supplement that comes from the shells of oysters. Oysters are marine mollusks that have an external hard shell primarily made of calcium carbonate (CaCO₃). The shells are collected, cleaned, and ground into a fine powder for use as a dietary supplement. Calcium is an important mineral used in the body for many functions such as bone health, muscle function, nerve transmission, and blood clotting.
Calcium oyster shell supplements are generally taken as a supplement for an alternate source of calcium. Oyster shells, being an all-natural source of calcium, provide a much better and safer source for humans who may not have adequate amounts of calcium through diet alone. Calcium from oyster shells is very bioavailable. In addition, since it is an all-natural source of calcium, many find it a more eco-friendly alternative compared to synthetic sources of calcium.
Calcium oyster shell supplements are typically available in the form of tablets, capsules, or powder. These supplements are designed for oral consumption, and the recommended dosage may vary depending on the product and the individual’s age, health status, and calcium needs.
Tablets and Capsules: Calcium oyster shell tablets or capsules must be swallowed with a full glass of water. Usually, calcium supplement is advised to take it with food for increasing calcium absorption and preventing discomfort or irritation of the stomach.
Powder: Calcium oyster shell powder can be mixed with water, juice, or smoothies. This form is ideal for people who may have difficulty swallowing pills or who like to mix the supplement into their daily beverages.
The body needs calcium in order to perform a variety of functions crucial for survival, such as helping to build bones, causing contraction of muscles, supporting nerve conduction, and facilitating the clotting of blood. When these supplements of oyster shell calcium are used, they dissolve in the stomach, and calcium ions move into the bloodstream from the tiny intestine.
Once calcium has entered the bloodstream, it will be taken to the bones, muscles, and other tissues that need it. Calcium supports bone density and strength by stimulating bone mineralization. It is also important for the contraction of muscles, the signaling of nerves, and proper heart rhythm.
The body maintains calcium levels through the use of hormones like parathyroid hormone (PTH) and calcitonin. When blood calcium levels are low, PTH is released to stimulate the release of calcium from the bones and increase the absorption of calcium from the intestines. If calcium levels are too high, calcitonin helps store excess calcium in the bones to prevent harmful buildup.
Although calcium oyster shell supplements are considered safe for most individuals, an overdose or specific medical conditions can cause side effects. Some possible side effects of calcium oyster shell supplements include the following:
Gastrointestinal Issues: High doses of calcium, including calcium oyster shell, may cause gastrointestinal discomfort, such as constipation, bloating, and gas. It is often recommended to take calcium with food to reduce these side effects.
Hypercalcemia: Taking too much calcium from any source, including calcium oyster shell, can lead to hypercalcemia, a condition where calcium levels in the blood become too high. Symptoms of hypercalcemia include nausea, vomiting, confusion, weakness, and kidney stones.
Kidney Stones: Excessive calcium intake, especially when combined with other risk factors like dehydration or a diet high in oxalates, may increase the risk of developing kidney stones.
Interaction with drugs: Calcium can interact with various drugs, such as calcium channel blockers, diuretics, and antibiotics. The effectiveness of the other drugs may be compromised, or other complications may occur. If you are taking other medications, consult a doctor before using calcium supplements.
Patients with kidney disease should therefore exercise extreme care when they are on calcium supplements including calcium oyster shell; since their impaired kidney function usually interferes with calcium metabolism, increasing the risk for deposition of calcium in any body organ.
Heart Disease: High calcium levels may have adverse effects on the cardiovascular system, especially in individuals with heart conditions such as arrhythmias. It is important to consult a healthcare provider if you have heart disease before using calcium supplements.
Pregnancy and Lactation: Calcium is an important requirement for pregnant and lactating women, but proper dosages must be followed. More than the recommended amount of calcium during pregnancy may cause such complications as kidney stones or poor fetal development. One should consult a doctor about how much to take.
Antibiotics: Calcium can interfere with the absorption of certain antibiotics like tetracyclines and quinolones, reducing their effectiveness.
Thyroid Medications: Calcium supplements can decrease the absorption of thyroid medications like levothyroxine, potentially leading to reduced effectiveness.
Diuretics: Some diuretics, particularly thiazides, can increase calcium levels in the blood, which might cause hypercalcemia when combined with calcium supplements.
Bisphosphonates: Calcium can interfere with bisphosphonates (used to treat osteoporosis), affecting their absorption and reducing their effectiveness.
The amount of calcium intake may depend on age, sex, and health status. For a considerable number of adults, recommended amounts of calcium intake have ranged from 1,000 mg to 1,200 mg per day.
Calcium oyster shell supplements usually contain 500 to 600 mg of calcium per tablet or capsule. Dosage varies by product and individual need. It’s best to consult a health care provider for recommendations based on your needs.
Generally, calcium oyster shell supplements are available in over-the-counter and thus do not require a doctor’s prescription. However, specific medical conditions or the susceptibility to calcium deficiency might warrant a higher dosage, wherein a healthcare provider would prescribe it or recommend a certain dose or a prescription-strength supplement.
