Summary, etc. Biochemical composition of seaweeds is known to vary with species and environment. <em>Kappaphycus alvarezii </em>is an important commercial source of carrageenans (gel-forming and viscosifying polysaccharides). The nutritional and mineral composition of three (brown, green and pale yellow) colour forms of edible seaweed <em>K. alvarezii</em> is investigated in the current study. The brown colour form of this seaweed contained highest ash content of (25.99±0.22 %), crude fibre (21.0±0.68 %), and protein (8.92±0.41 %), while, the green form had highest carbohydrate (22.0±0.00 %) and sulphate (5.89±0.00 %) content. On the other hand, the pale yellow colour form had highest lipid content (0.72±0.00 %). Amongst the 17 minerals analyzed, highest total mineral macro-elements (<em>viz</em>. Na, K, Ca and Mg) were recorded in the brown form (18.8±0.71 g/100 g d wt) followed by the pale yellow (17.3±1.07 g/100 g d wt) and green colour form (11.9±1.22 g/100 g d wt). The micro-elements varied within the three colour forms; however, the brown colour form had maximum micro-element content (P, Cd, Pb, As, Hg, Cr, Zn, Cu, Fe, Mn, Co, Mo and Ni; 19.96±0.24mg/100 g d wt), followed by green (8.6±0.64 mg /100 g d wt) and pale yellow form (7.15±0.58mg /100 g d wt). On the basis of this study, it could be said that these three colour forms (<em>i.e</em>. brown, green and pale yellow) of <em>Kappaphycus alvarezii</em> could be utilized as a condiment in the omnivorous diet; however, a daily intake of 5.68 g d wt is recommended in case of the brown form, while in case of the green and pale yellow form a maximum daily intake of 9.55 and 10.5 g d wt, respectively is recommended. The study also reveals that the three colour-forms differed in their nutritional and mineral composition.
