What Actually Works for Acne?

Acne supplements promise clear skin from within. Some can help, especially if deficiencies or inflammation are involved. But skincare and possibly medication matter more.

TL;DR

Best evidence: Zinc (inflammatory acne), Omega-3 (anti-inflammatory). Moderate evidence: Vitamin A (if deficient), Probiotics (gut-skin axis). Doesn't work: Most "clear skin" supplements, mega-dose vitamins.

A

Strong Evidence

Zinc
30-45mg daily15 studies

Reduces inflammatory acne, may rival low-dose antibiotics

8-12 weeks

Note: Take with food. Don't exceed 40mg long-term without copper.

Omega-3 Fatty Acids
1-2g EPA+DHA daily8 studies

Reduces inflammation, may reduce acne lesion count

10-12 weeks

Note: Anti-inflammatory effect helps inflammatory acne.

B

Moderate Evidence

Vitamin A (if deficient)
5000-10000 IU daily6 studies

Deficiency can worsen acne. Retinoids are vitamin A derivatives.

8-12 weeks

Note: Don't mega-dose. Toxicity is real. Pregnant women avoid.

Probiotics
Strain-specific5 studies

Gut-skin axis may influence acne

8-12 weeks

Note: Limited but growing evidence for gut-skin connection.

Pantothenic Acid (B5)
1-2g daily4 studies

May reduce sebum production

8-12 weeks

Note: Some promising studies, but high doses needed.

C

Limited Evidence

Vitamin D
1000-4000 IU daily4 studies

Deficiency associated with acne. Correction may help.

12 weeks

Note: Only helps if deficient.

Green Tea Extract
500mg EGCG daily3 studies

Antioxidant and anti-inflammatory

8-12 weeks

Note: Topical EGCG may work better than oral.

F

Doesn't Work / Overhyped

May actually WORSEN acne in some people

N/A

Note: Biotin can cause breakouts. Avoid if acne-prone.

"Clear Skin" Blends
Various

Usually underdosed zinc with random herbs

N/A

Note: Check doses. Usually not therapeutic.

No evidence for acne reduction

N/A

Note: Good for skin aging, not acne.

Real Talk

Acne is multifactorial: hormones, bacteria, inflammation, sebum production. Supplements can help with inflammation and nutrient deficiencies but won't replace proper skincare or medication for moderate-to-severe acne. See a dermatologist if it's significantly affecting you.

What Else Actually Helps

  • Topical retinoids. gold standard for acne
  • Benzoyl peroxide. kills acne bacteria
  • Salicylic acid. unclogs pores
  • Low glycemic diet. high GI foods may worsen acne
  • Reduce dairy (maybe). some evidence for dairy-acne link

The Bottom Line

Zinc is the standout supplement for inflammatory acne. Omega-3 helps reduce inflammation. Don't take biotin if acne-prone. Skincare matters more than supplements.
