Softgel
One sealed piece
A softgel is a one-piece, sealed format with a soft outer shell, most often used for oil-based ingredients. Vitamin D3 1000 IU and omega-3 1000 mg are the clearest examples on Indonesian retail pages, and both use this format almost exclusively. Softgels are small, need no preparation, and are usually taken with food.
On the label, look for the ingredient amount per softgel and the total count in the pack, since those two numbers together decide how long the bottle lasts. Because the shell is sealed, softgels do not split or crumble the way some compressed formats can — which also means you cannot halve one to adjust a serving.
