Bioavailable ingredients are those that the body can readily absorb. This is crucial because only absorbed compounds can effectively benefit the body functionally. At Nutrafol, we prioritize using premium, standardized, bioavailable ingredients in our supplements to target key root causes of hair thinning from within.

Ingredient amounts for Nutrafol supplement products are determined by rigorous research at the ingredient level to select serving sizes that appropriately address key root causes of hair thinning. Some nutrients are included in our products above 100% Daily Value since we utilize research specific to addressing root causes—this is slightly different than if we look at recommended daily values to maintain health, as put out by the U.S. FDA.

Additionally, each formula undergoes a safety evaluation to validate that nutrient and ingredient limits are within range for long-term use.

Nutrafol determines effective serving sizes for our dietary supplements by conducting rigorous research to fully understand how each ingredient contributes to addressing key root causes of hair thinning targeted by the product. Nutrafol Hair Growth Nutraceuticals also undergo clinical testing to evaluate the efficacy of the formulation as a whole, adding further rigor to the research behind each of our formulations.

Our Synergen Complex® blends are combinations of ingredients that are the core foundation of our Hair Growth Nutraceuticals. These blends are set apart because they are designed with standardized ingredients in precise ratios to effectively target key root causes of hair thinning at specific biological life stages.

Nutrafol Postpartum was developed with an OBGYN using breastfeeding-friendly ingredients to target key root causes of postpartum hair thinning. All of our ingredients were chosen to help support recovery from nutrient gaps and the physical and emotional stress that can lead to hair thinning in postpartum women during a time when they may be breastfeeding. Likewise, all ingredients and their amounts were selected based on published data by the National Institutes of Health (NIH), National Academies, or other evidence-backed research showing efficacy and safety. Our in-house clinical and science innovation teams monitor for any changes in safety.

We source all of our ingredients based on an outlined specification and profile, by our team of formulators, for each raw material to ensure the quality and consistency is always as intended. Verification of all ingredient technologies during formulation assures they fit in the target delivery format, can be manufactured, and remain effective in each batch.

Our suppliers are regularly audited to ensure compliance with certifications, FDA registration and Good Manufacturing Practices. All finished product manufacturing is conducted in U.S. GMP-certified facilities, using domestic and imported ingredients, and every lot is thoroughly tested to meet our exacting standards. All of our supplements are third-party certified Non-GMO Tested through the IGENTMprogram.

Every ingredient, and every formulation, undergoes extensive research by our team of internal biologists, chemists, and clinical experts to ensure we continue to set the standards and deliver meaningful results. Each ingredient is selected based on substantial evidence to meet the desired.
