NaturesPlus PABA 1000 mg Sustained Release is a highly effective, single-ingredient PABA supplement. Its standout feature is the 1000mg dose, which is among the highest available and highly sought after by individuals specifically targeting hair repigmentation or certain skin conditions where PABA is believed to play a role. The 'sustained release' formulation is a significant advantage, as it aims to improve absorption and minimize potential side effects like flushing, which can sometimes occur with immediate-release PABA at high doses. Online reviews often highlight its efficacy for these specific hair and skin goals. Nutritionists acknowledge PABA's potential for these applications, particularly for its role in supporting hair color. This product offers excellent value for a high-dose, specialized PABA product, making it a best-in-class option for those whose primary need is concentrated PABA.
