NEFAs directly reduce Mg²⁺ concentrations. Linear regression analyses of Mg²⁺ and NEFA concentration in (a) BSA dissolved in 1 mmol/l MgCl₂ (y = −0.12x + 0.83, r² = 0.97, p ≤ 0.05), (b) FBS (y = −0.10x + 1.36, r² = 0.90, p ≤ 0.05) and (c) MgCl₂ solution (y = −0.08x + 1.00, r² = 0.99, p ≤ 0.05). Results from one representative experiment are shown. The experiment was repeated three additional times with similar results
