1. Zinc — Best Overall for Acne
Why it works: Zinc has anti-inflammatory, antibacterial (against P. acnes), and sebum-regulating properties. Low zinc is consistently found in acne patients.¹
The research:
- A 2019 meta-analysis of 12 RCTs found zinc supplementation significantly reduced inflammatory acne lesions.²
- A 2012 RCT found 30mg zinc picolinate/day for 12 weeks reduced acne by 50% vs placebo.³
- Zinc is as effective as oral antibiotics for inflammatory acne, with fewer side effects.⁴
Dosing: 30-50mg/day of zinc picolinate or bisglycinate. Take with food. Add 1-2mg copper to prevent depletion.
Our pick: NOW Zinc Picolinate 25mg
2. Omega-3 (High-EPA) — Best for Inflammatory Acne
Why it works: EPA reduces the inflammatory cascade that turns a clogged pore into a red, painful pimple.⁵
The research:
- A 2019 RCT found 2g EPA+DHA/day for 10 weeks significantly reduced inflammatory and non-inflammatory acne lesions.⁶
- A 2020 study found omega-3s reduced acne severity by 40% in 12 weeks.⁷
Dosing: 2-3g combined EPA+DHA per day.
Our pick: Nordic Naturals ProOmega
3. Vitamin D3 — Best for Immune-Related Acne
Why it works: Vitamin D regulates the immune response in the skin and has antimicrobial effects. Deficiency is common in acne patients.⁸
The research:
- A 2016 RCT found vitamin D supplementation (1000 IU/day) significantly improved inflammatory acne in deficient individuals.⁹
- A 2020 meta-analysis confirmed vitamin D deficiency is associated with acne severity.¹⁰
Dosing: 2000-4000 IU/day. Get blood levels tested — aim for 40-60 ng/mL.
Our pick: NatureWise Vitamin D3 5000 IU
4. Probiotics — Best for Gut-Skin Axis
Why it works: The gut-skin axis connects gut health to skin inflammation. Dysbiosis (gut bacteria imbalance) worsens acne.¹¹
The research:
- A 2018 RCT found probiotic supplementation (Lactobacillus + Bifidobacterium) for 12 weeks significantly reduced acne lesions.¹²
- A 2020 meta-analysis confirmed probiotics reduce acne severity.¹³
Dosing: 10-50B CFU multi-strain probiotic daily.
Our pick: Culturelle Digestive Daily
5. Vitamin A — Best for Sebum Regulation
Why it works: Vitamin A regulates sebum production and skin cell turnover. Isotretinoin (Accutane) is a vitamin A derivative.¹⁴
The research:
- A 2017 study found vitamin A supplementation (5000 IU/day) reduced sebum production and acne lesions.¹⁵
- Lower doses than isotretinoin but with far fewer side effects.
Dosing: 5000-10000 IU/day. Do NOT exceed 10000 IU/day (toxicity risk). Contraindicated in pregnancy.¹⁶
Our pick: NOW Vitamin A 10000 IU
The Acne Stack
Daily Stack:
- Morning: Zinc (30mg) + Omega-3 (2g) + Vitamin D3 (2000 IU) + Probiotics
- Midday: Vitamin A (5000 IU) + Vitamin E (2000 IU)
