Cuttlebone
Also known as: Cuttlebone, Cuttlefish bone
Overview
Cuttlebone is a hard, calcareous structure primarily composed of calcium carbonate (CaCO3), found in cuttlefish. It serves various purposes, including buoyancy and structural support for the animal. In the supplement sector, it is recognized as a mineral source, predominantly for calcium. While commonly used in powder or capsule form, research specifically focusing on cuttlebone as a dietary supplement is limited. Most evidence stems from the ecological study of cuttlebone, as well as its physical properties, rather than clinical outcomes. Its utility is most significant for individuals requiring supplemental calcium, as the benefits of calcium in maintaining bone density and supporting muscle function are well documented, though specific studies on cuttlebone are scarce.
Benefits
Cuttlebone is primarily valued for its high calcium content. General calcium supplementation is well-researched, showing benefits such as improved bone health and reduced risk of osteoporosis, particularly in populations at risk due to dietary deficiencies or increased needs. As cuttlebone is a calcium source, one can extrapolate that it may confer similar benefits, yet specific quantified outcomes directly associating cuttlebone with benefits have not been established. Research indicates that adequate calcium intake contributes to maintaining bone density and muscle function, but direct clinical evidence for cuttlebone is lacking.
How it works
Calcium from cuttlebone, when ingested, is absorbed by the digestive tract and integrated into the body's calcium pool. This mineral plays a critical role in the biological pathways related to bone mineralization, muscle contraction, and nerve signaling. The presence of calcium ions influences various molecular targets, including receptors and channels involved in these physiological processes. Although the exact absorption efficiency of cuttlebone's calcium is not well-documented, calcium carbonate is generally understood to have moderate bioavailability, particularly when consumed with food.
Side effects
Cuttlebone is generally considered safe for most individuals when taken as a calcium supplement; however, specific side effects related to cuttlebone are not extensively documented. Common side effects of calcium supplementation, occurring in more than 5% of users, may include gastrointestinal upset, constipation, or bloating. Less frequently, at 1-5%, excessive calcium intake can increase the risk of kidney stones. Rarely reported side effects occur in less than 1% of users, though specific instances for cuttlebone are unknown. Interactions with certain medications, such as tetracyclines and bisphosphonates, can occur, necessitating caution. High calcium supplementation is contraindicated in individuals with a history of kidney stones or those with specific renal conditions. Pregnant or lactating women, as well as individuals with underlying kidney issues, should consult a healthcare provider before use.
Dosage
While a specific minimum effective dose for cuttlebone is not established, general guidelines recommend adult calcium intake to be between 500-1000 mg per day. The Tolerable Upper Intake Level for calcium is set at 2500 mg per day. To optimize absorption, it is advised to take calcium supplements, including cuttlebone-based products, with meals. The biological absorption of calcium can also be supported by adequate vitamin D levels, highlighting the importance of co-factors. Adjustments to dosage may be necessary based on individual needs, health status, and dietary intake.
