Can calcium and omega three affect the absorption of each other?

Yes, calcium and omega-3 fatty acids can affect each other's absorption, but the interaction is complex. High calcium intake may inhibit the absorption of omega-3s by competing for binding sites or altering the gut environment. Conversely, omega-3 fatty acids can improve the absorption of certain nutrients, including calcium, by promoting a healthier gut environment. However, the clinical significance of this interaction is still an area of ongoing research.
