Vitiligo

Vitiligo is a skin condition characterized by patches of skin losing their skin pigment. It's cause isn't clear, but genetic risk factors and a family history of autoimmune disorders are thought to contribute to its development.

Evidence-Based Protocol

Supplement stack ranked by research quality

Limited Evidence

Primary Stack (Tier 1)

Vitamin DC
2000-4000 IU daily (higher if deficient)

Immune modulation; deficiency common in vitiligo; may help with repigmentation in combination with other treatments

10 studies | 500 participants
Vitamin B12 and Folic AcidC
B12: 1000mcg daily; Folic acid: 5mg daily

Some studies show repigmentation with B12/folic acid plus sun exposure; supports melanocyte function

8 studies | 300 participants

Supporting Stack (Tier 2)

Ginkgo BilobaC
60-120mg standardized extract twice daily

Antioxidant and anti-inflammatory; small studies suggest may halt progression and promote repigmentation

5 studies | 150 participants
Antioxidant ComplexC
Combination of vitamin C, E, alpha-lipoic acid, zinc, selenium

Oxidative stress implicated in vitiligo; antioxidants may protect melanocytes

6 studies | 250 participants
ZincC
30-50mg daily

Antioxidant; some studies show benefit as adjunctive therapy; supports melanocyte function

5 studies | 200 participants
PhenylalanineC
50-100mg/kg daily with sun exposure (requires medical supervision)

Precursor to melanin; studied with UV therapy for vitiligo

6 studies | 200 participants
CopperC
1-2mg daily (do not exceed)

Essential for tyrosinase enzyme in melanin production; deficiency may impair pigmentation

4 studies | 100 participants

How It Works

Vitiligo is an autoimmune condition where the immune system attacks melanocytes (pigment-producing cells), causing white patches on the skin. It affects about 1% of the population worldwide and can occur at any age.

TYPES:

•Non-segmental (generalized): Most common; symmetrical patches; can spread
•Segmental: One side of body; usually stable; often in younger people
•Universal: Most of body affected (rare)

ASSOCIATED CONDITIONS:

•Thyroid disease (especially Hashimoto's)
•Type 1 diabetes
•Addison's disease
•Pernicious anemia
•Other autoimmune conditions

WHAT TRIGGERS IT:

•Genetic predisposition
•Autoimmune attack on melanocytes
•Oxidative stress
•Stress (can trigger or worsen)
•Skin trauma (Koebner phenomenon)
•Sunburn

TREATMENT OPTIONS:

•Topical corticosteroids: First-line for localized vitiligo
•Calcineurin inhibitors: Tacrolimus, pimecrolimus (especially for face)
•Phototherapy: NB-UVB is gold standard for widespread disease
•JAK inhibitors: Ruxolitinib cream (Opzelura) - newly approved
•Depigmentation: For very extensive disease (remove remaining pigment)
•Surgical: Grafting for stable, localized disease

SUN PROTECTION:

•Vitiligo patches burn easily
•Use high SPF sunscreen on depigmented areas
•Paradoxically, controlled sun exposure can help with treatment

* Vitamin D is commonly deficient and supports immune regulation.

* B12 and folic acid have been studied for repigmentation.

* Ginkgo biloba shows promise in small studies.

* Antioxidants may help protect remaining melanocytes.

Expected timeline: Repigmentation is slow - takes months. Best results with combination approaches. Supplements are adjunctive to medical treatment.

Type 2 diabetes (T2D) is a disease in which blood glucose levels are too high. It is characterized by insulin resistance in muscle, fat, and pancreas cells and an inability of the pancreas to manufacture enough insulin to control blood glucose levels. T2D is strongly associated with excess body fat, and weight loss induced by lifestyle changes is extremely effective for treating T2D.
