Beta-sitosterol has been
shown to inhibit 5-alpha reductase’s creation of
dihydrotestosterone, a hormone that shuts down hair
production.
60–130
mg/day
No significant side
effects have been reported.
Biotin
Biotin, a water-soluble B
vitamin, aids in metabolism of protein, fats, and carbohydrates and
is believed to be associated with hair growth.
30 mcg/day
Other than isolated
incidents, no significant side effects have been
reported.
Saw palmetto
(Serenoa repens)
Studies suggest saw
palmetto’s fatty acids and sterols hinder the formulation of
dihydrotestosterone.
100 mg, 2x/day
Other than isolated
incidents, no significant side effects have been
reported.
Stinging nettle root
(Urtica dioica)
Compounds in stinging
nettle root appear to hamper hormones and proteins that carry
testosterone, which may explain how it inhibits
dihydrotestosterone.
120 mg standardized
extract, 2x/day
Nettle root may
occasionally cause mild stomach upset. Take with food to lessen
risk of this reaction.
