Kirkland Signature Psyllium Fiber Capsules vs Yerba Prima Psyllium Husks Veg Caps

Both are plain psyllium husk in capsules, so the real difference is dose per capsule and capsule material. Kirkland packs 720 capsules per bottle and needs two per serving, which suits daily long-term use. Yerba Prima needs four capsules per serving for 2.2 g of fiber, so you swallow more pills for the same fiber, but it is a single-ingredient, non-GMO, Prop 65 compliant product. Buy Kirkland for volume and daily habit; buy Yerba Prima if you want a smaller, certified-clean label.

• Choose the Kirkland Signature if you take fiber every day and want a large capsule count with a simple two-capsule serving.
• Choose the Yerba Prima if you want a single-ingredient, non-GMO, Prop 65 compliant psyllium capsule and do not mind four capsules per serving.
