Jarrow Formulas PS 100 provides 100 mg of phosphatidylserine (PS) per softgel, derived from sunflower lecithin rather than soy, making it a suitable choice for those avoiding soy-based ingredients. The formula uses Sharp-PS, a concentrated and stable form of this naturally occurring phospholipid, which is found in cell membranes throughout the body and is particularly abundant in the brain.
Each pack contains 60 softgels. Phosphatidylserine is a phospholipid that forms part of the structural matrix of cell membranes, and Jarrow Formulas has built a strong reputation for using well-sourced, clearly labelled ingredients across their range. The sunflower-derived lecithin source means this product is free from soy, which may appeal to those with specific dietary preferences or sensitivities.
The softgel format is easy to swallow and widely favoured by those who prefer capsule-based supplements over powders. Whether you follow a particular dietary protocol or simply prefer soy-free formulations, PS 100 from Jarrow Formulas is a straightforward, clearly dosed supplement from an established name in nutritional science.
