PbSin 18, also written pb-sin® 18 or pbsin18, is a food supplement in capsule form for adults who want a simple daily companion for their weight-management routine. It is made to sit alongside the habits that make the difference: balanced meals, sensible portions, regular movement and a routine you can keep.
Each capsule combines chromium and zinc with guarana extract, apple cider vinegar extract, inulin from Jerusalem artichoke and the amino acids L-leucine and L-glutamine. The capsule shell is plant-based HPMC and the formula is free from additives.
Everyday life can quietly work against your goals. Long days at a desk, irregular meals, snacking between them and flagging energy all make it harder to stick with the habits that bring steady progress.
PbSin 18 does not replace a balanced diet or exercise. It supports them with nutrients such as chromium, which contributes to normal macronutrient metabolism and to the maintenance of normal blood glucose levels, taken as a single capsule once a day.
