Ingredient Research Summary

Vitamin D (as Cholecalciferol) — 25 mcg

Research Overview

Vitamin D has been studied in relation to telogen effluvium, alopecia areata, and hair follicle cycling. Existing literature suggests vitamin D plays a role in follicular signaling and healthy hair cycling.

Research Notes

  • Human evidence exists in hair-loss-related settings
  • Most studies focus on deficiency correction or adjunctive use
  • Current evidence is stronger in deficiency-related conditions rather than universal standalone supplementation

Niacin (as Niacinamide) — 50 mg

Research Overview

Niacin-related compounds have been explored for their potential role in supporting scalp circulation and visible hair fullness.

Research Notes

  • Existing human evidence mainly involves topical niacin derivatives
  • Oral niacinamide research remains more limited
  • Evidence should be interpreted as ingredient-family support rather than direct proof for this exact oral dose

Iron (as Ferrous Bisglycinate Chelate) (Ferrochel®) — 10 mg

Research Overview

Iron is one of the most commonly discussed nutrients in relation to hair shedding, particularly in iron-deficiency-related telogen effluvium.

Research Notes

  • Evidence is strongest when low ferritin or deficiency is present
  • Iron repletion may support healthy hair cycling in deficiency-related cases
  • Universal supplementation evidence remains mixed

Zinc (as Zinc Bisglycinate Chelate) (Albion®) — 15 mg

Research Overview

Zinc is an essential trace mineral involved in cellular repair, protein synthesis, and follicle health.

Research Notes

  • Strongest evidence exists in deficiency-related hair shedding
  • Studied in telogen effluvium and alopecia-related settings
  • Zinc balance appears important for normal follicle function

Selenium (as L-Selenomethionine) — 70 mcg

Research Overview

Selenium plays a role in antioxidant systems and normal biological processes related to skin and hair.

Research Notes

  • Evidence is primarily biological and deficiency-related
  • Strong standalone human hair-growth trials remain limited
  • Often used as supportive formula rationale rather than direct standalone efficacy

Copper (as Copper Gluconate) — 2 mg

Research Overview

Copper contributes to connective tissue biology and pigment-related processes associated with healthy hair.

Research Notes

  • Existing evidence is largely mechanistic or peptide-related
  • Direct oral copper supplementation studies for hair growth remain limited

Supporting Studies

  2. https://pubmed.ncbi.nlm.nih.gov/24371385/

Ashwagandha Root Extract — 300 mg

Research Overview

Ashwagandha has been extensively studied for stress response and cortisol regulation. Stress-related shedding and telogen effluvium are commonly associated with elevated stress pathways.

Research Notes

  • Strong evidence exists for stress and cortisol modulation
  • Hair-related benefits are primarily indirect through stress pathway support
  • Commonly referenced in stress-related wellness protocols

Saw Palmetto Fruit Extract — 320 mg

Research Overview

Saw palmetto is one of the most researched botanical ingredients in relation to DHT-related hair concerns.

Research Notes

  • Human studies suggest supportive benefits in androgen-related hair thinning
  • Research often compares pathways associated with DHT activity
  • Evidence remains supportive rather than definitive

Methodology & Evidence Interpretation

The references included in this document were selected based on:

  • Ingredient relevance to hair biology
  • Human clinical evidence when available
  • Mechanistic support for follicle function
  • Nutrient deficiency literature
  • Peer-reviewed scientific publication availability
  • PubMed-indexed references

Evidence quality may vary by ingredient. Some ingredients have direct human clinical evidence related to hair shedding or follicle support, while others are supported primarily through biological plausibility, deficiency correction research, stress pathway modulation, antioxidant mechanisms, or supportive wellness research.

This document intentionally avoids overstating conclusions beyond the currently available body of evidence.

Conclusion

Hair health is multifactorial and may be influenced by stress, hormones, nutrient status, inflammation, oxidative stress, genetics, lifestyle, and overall wellness.
