Rosacea Support
About this protocol
Where to start
Triggers matter more than supplements. Before adding anything from this stack, spend 4-6 weeks keeping a trigger journal. The most consistent rosacea triggers are heat (hot drinks, hot showers, hot weather, exercise), sun exposure, alcohol (red wine especially), spicy food, stress, extreme cold/wind, and certain skincare ingredients. Identifying and removing your personal triggers will outperform any supplement on this list.
Start with oral niacinamide at 500 mg twice daily. The strongest topical evidence is for niacinamide-containing moisturizers (Draelos 2005 showed barrier improvement in rosacea), but oral niacinamide also modulates inflammation and supports barrier function. Pair with a topical niacinamide moisturizer for compound effect.
Add zinc at 30-50 mg elemental daily, taken with food. The Sharquie 2006 placebo-controlled trial used 100 mg zinc sulfate three times daily (about 100 mg elemental) and showed clinically meaningful improvement, but that dose causes significant GI upset and risks copper deficiency over time. A more sustainable 30-50 mg/day with breakfast captures most of the anti-inflammatory effect with far less GI burden.
Consider omega-3 EPA-dominant at 2 g combined daily if you have ocular rosacea, dry-eye symptoms, or meibomian gland dysfunction. The Bhargava 2013 RCT showed omega-3 improved tear film and ocular surface metrics, with the strongest signal in blepharitis and meibomian gland disease — the same mechanisms driving ocular rosacea.
Treat quercetin as experimental. Mast cell activation is now recognized as a key driver in rosacea (Muto 2014), and quercetin stabilizes mast cells more effectively than cromolyn in vitro (Weng 2012). Trial evidence in rosacea specifically is absent. If flushing or vascular reactivity is your dominant symptom, a 250-500 mg twice-daily trial for 8-12 weeks is reasonable; if no change, drop it.
See a dermatologist if any of the following apply: persistent papules/pustules unresponsive to OTC care, visible vessels you want treated (vascular laser or IPL), eye involvement (gritty, burning, recurrent styes), rhinophyma or early phymatous changes, or symptoms affecting your quality of life or self-image. Topical ivermectin (Soolantra), azelaic acid, brimonidine, and oral sub-microbial doxycycline are the high-value prescription tools.
Re-evaluate at 12 weeks. If your trigger journal plus this stack hasn't reduced flare frequency or background redness, the bottleneck is almost certainly topical/prescription rather than nutritional.
4 nutrients
Start here
Strongest evidence — the foundation of the stack.
Niacinamide (Nicotinamide)
500 mg twice daily with food (avoid niacin/nicotinic acid — it causes flushing, which is exactly what you don't want in rosacea)Niacinamide modulates inflammation by inhibiting NF-κB signaling, supports ceramide biosynthesis in the stratum corneum (Tanno 2000), and has direct effects on sebum regulation. The strongest evidence in rosacea is for topical niacinamide moisturizers (Draelos 2005 showed clinical benefit on barrier function and patient-rated outcomes in 50 rosacea subjects), and oral niacinamide is mechanistically aligned but has thinner direct-rosacea trial data. CRITICAL: use niacinamide (nicotinamide), NOT niacin (nicotinic acid). Niacin causes prostaglandin-D2 mediated cutaneous flushing — exactly the opposite of what a rosacea patient wants. Topical niacinamide-containing moisturizers (often labeled 4-5% niacinamide) layer well with oral supplementation.[1, 2, 3, 4]
Zinc (Picolinate or Gluconate)
30-50 mg elemental zinc daily with breakfast; cycle in copper (1-2 mg) if used long-termZinc has direct anti-inflammatory effects, supports skin barrier protein synthesis, and modulates innate immunity — including the cathelicidin pathway implicated in rosacea pathophysiology. The Sharquie 2006 randomized double-blind placebo-controlled crossover trial used oral zinc sulfate 100 mg three times daily and showed statistically significant reduction in rosacea severity versus placebo, with GI upset in only 12% of subjects. We dose lower (30-50 mg elemental) for better long-term tolerance and to avoid copper depletion. Effect builds over 8-12 weeks. If you're already taking zinc for another reason, don't stack — total elemental zinc above 40 mg/day chronically requires copper supplementation.[5, 6]
Add if needed
Add these only if the foundation isn't enough.
Omega-3 (EPA-dominant fish oil)
2 g combined EPA+DHA daily (EPA-dominant), with a fat-containing meal — especially if ocular rosacea or dry-eye symptomsOmega-3 EPA/DHA reduces pro-inflammatory eicosanoid production and supports the lipid composition of meibomian gland secretions — the gland dysfunction at the heart of evaporative dry eye and ocular rosacea. The Bhargava 2013 RCT (518 dry-eye patients, 3 months) found omega-3 improved Schirmer test, tear breakup time, and conjunctival impression cytology versus placebo, with the strongest signal in blepharitis and meibomian gland disease. For cutaneous rosacea, the evidence is more indirect — general anti-inflammatory effect rather than rosacea-specific trial data. Highest-value indication: rosacea patients with ocular involvement (gritty eyes, recurrent styes, blepharitis).[7, 8]
Experimental
Emerging evidence — try last, only if curious.
Quercetin
250-500 mg twice daily with food, often paired with bromelain or vitamin C for absorptionMast cells are now recognized as central effectors of rosacea-associated inflammation: Muto 2014 demonstrated that mast cells mediate cathelicidin-initiated skin inflammation in murine rosacea models, and mast cell counts are elevated in human rosacea-affected skin. Quercetin is a flavonoid mast cell stabilizer; the Weng 2012 study showed it outperformed cromolyn in suppressing human mast cell cytokine release and improved contact dermatitis and photosensitivity in small human trials. However, NO controlled trial has tested quercetin in rosacea directly. The mechanism is plausible and the safety profile is favorable, but treat this as exploratory. Most useful target: patients whose dominant symptom is flushing or environmental reactivity rather than persistent papules.[9, 10, 11]
Warnings
Lifestyle improvements
Identify your triggers — this is the single highest-leverage action
Keep a 4-8 week flare journal noting food, drink, weather, skincare products, stress, and any flushing or worsening within 30-60 minutes. The most commonly reported rosacea triggers, drawn from National Rosacea Society surveys and clinical experience: sun exposure (#1 cited trigger), emotional stress, hot weather, alcohol (red wine in particular), spicy food, heated beverages (coffee, tea), exercise-induced overheating, cold wind, certain skincare ingredients (alcohol-based toners, strong AHAs/BHAs, fragrance, witch hazel), and humid heat. Your personal trigger profile matters more than any general list — the pattern in your own journal beats the average.
Daily mineral SPF 30+ — non-negotiable
UV is the most consistently identified rosacea trigger, and chronic UV exposure worsens telangiectasia and erythema. Use a broad-spectrum SPF 30 or higher every morning, year-round, even in winter and on cloudy days. Mineral (zinc oxide, titanium dioxide) sunscreens are usually better tolerated than chemical filters on rosacea-prone skin — chemical filters can sting and trigger flushing. Tinted mineral sunscreens add iron oxides that block visible light (relevant for melasma and post-inflammatory pigmentation in skin of color). Reapply if outdoors for extended periods.
Gentle skincare — strip the routine down
Rosacea skin reacts poorly to active ingredients that work fine on neutral skin. Eliminate: alcohol-based toners, fragranced cleansers, witch hazel, strong glycolic/salicylic acid, retinol unless prescribed and titrated by your dermatologist, physical scrubs, brushes, and hot water on the face. Keep: a fragrance-free non-foaming gentle cleanser, a barrier-supporting moisturizer (look for ceramides, glycerin, niacinamide, panthenol), and mineral sunscreen. That's the entire routine for most rosacea patients. Adding actives back in is something to negotiate with a dermatologist, slowly.
Lukewarm water on the face, always
Hot water dilates facial vessels and triggers flushing. Wash with lukewarm or cool water, pat dry, apply moisturizer while skin is still slightly damp. Skip facial saunas, steam treatments, and very hot showers angled at the face.
Reduce alcohol — especially red wine — if it's a trigger
Alcohol is one of the most commonly reported triggers, and red wine specifically contains histamine and tyramine that drive flushing beyond ethanol's vasodilatory effect. You don't necessarily have to abstain — but track it in your trigger journal. Many rosacea patients tolerate spirits or white wine better than red. If alcohol consistently triggers a 24-72 hour flare, the cost-benefit calculus changes.
Spicy food and hot drinks — case by case
Capsaicin activates TRPV1 receptors in facial vasculature and triggers flushing in susceptible individuals. Hot drinks (coffee, tea) trigger via temperature, not caffeine — iced coffee usually doesn't flare. If your journal flags either, modify; if not, don't restrict unnecessarily.
Address ocular hygiene if you have ocular subtype
Ocular rosacea is underdiagnosed and undertreated. If your eyes feel gritty, burn, water excessively, or you get recurrent styes/chalazia: warm compresses (a clean washcloth at warm-not-hot temperature for 5 minutes, twice daily), gentle lid hygiene with a dedicated lid cleanser (hypochlorous acid spray or diluted baby shampoo), and an ophthalmology referral. Omega-3 supplementation is genuinely useful here (Bhargava 2013). Severe ocular rosacea may need oral doxycycline.
Stress management — real, not optional
Stress is one of the top three reported triggers. Daily breathwork, regular aerobic exercise (in a cool environment), CBT for chronic skin disease, and treating coexisting anxiety/depression all reduce flare frequency. Rosacea has measurable quality-of-life and self-esteem impact — addressing it is part of the treatment, not a soft add-on.
Discuss prescription topicals with a dermatologist
The high-value prescription tools, in rough order of impact: topical ivermectin (Soolantra) addresses the Demodex component and reduces papulopustular lesions; topical metronidazole and azelaic acid are first-line for inflammatory papules; brimonidine reduces background erythema (but watch for rebound); oral sub-microbial doxycycline (Oracea 40 mg) for moderate inflammatory disease without antibiotic effect; vascular laser or IPL for persistent telangiectasia. Supplements are complementary to these, not a substitute.
Don't ignore phymatous changes
Early phymatous rosacea (thickening skin on the nose, chin, cheeks, ears) is more treatable than late. If you notice gradual skin thickening, see a dermatologist — early oral isotretinoin or procedural treatment changes the trajectory. Established rhinophyma typically requires laser or surgical debulking.

Eczema Support
skin conditions
Atopic dermatitis (eczema) is a chronic, relapsing inflammatory skin disease affecting 10-20% of children and 1-3% of adults. The pathology is a tripod: skin barrier dysfunction (often driven by filaggrin gene mutations), Th2-skewed immune dysregulation, and an altered skin microbiome with reduced diversity and Staphylococcus aureus overgrowth. Flares cycle around triggers — irritants, allergens, stress, infection, dry climate — and conventional treatment is rightly aggressive in moderate-to-severe disease: daily emollients, topical corticosteroids and calcineurin inhibitors (tacrolimus, pimecrolimus), and for refractory or extensive disease, biologics like dupilumab. Supplements occupy a supportive role here. They can blunt systemic inflammation, support barrier function, and nudge immune balance — but they don't replace the topical and systemic backbone. If your eczema is moderate-to-severe, scarring you, disrupting sleep, or unresponsive to good topical care — see a dermatologist. Modern biologics (dupilumab, tralokinumab) have transformed outcomes for adult atopic dermatitis. Supplements work best as one layer of a multi-modal plan that always includes daily emollient routine and trigger management.
Psoriasis Support
skin conditions
Psoriasis is a chronic, immune-mediated inflammatory disease affecting 2-3% of adults. The hallmark is accelerated keratinocyte turnover — skin cells replicating every 3-5 days instead of the normal 28-30 — driven by a Th17/IL-23 immune axis. Clinically that shows up as well-demarcated red plaques with silvery scale, classically on the elbows, knees, scalp, and lower back. Psoriasis is not just a skin disease: it carries substantial comorbid risk. Roughly 30% of patients develop psoriatic arthritis, and the cohort as a whole runs higher cardiovascular disease, metabolic syndrome, and depression rates than the general population. Treatment is genuinely multi-modal — topical corticosteroids and vitamin D analogs (calcipotriol) for limited disease, phototherapy for wider involvement, and systemic biologics targeting IL-17 (secukinumab/Cosentyx), IL-23 (risankizumab/Skyrizi, guselkumab/Tremfya, ustekinumab/Stelara), or TNF-alpha (adalimumab/Humira) for moderate-to-severe disease. If you have moderate-to-severe psoriasis — significant body surface area, scalp/genital/palmar-plantar involvement, joint symptoms, or quality-of-life impact — see a dermatologist. The biologics era has been transformative; PASI 90 (90% lesion clearance) is now a realistic goal for most patients, not the exception. Supplements occupy a supportive role: they can blunt systemic inflammation, correct deficiencies that worsen disease activity, and address the cardiometabolic comorbidity burden. They don't replace appropriate dermatologic care for anything beyond mild localized disease.
Fibromyalgia Support
chronic illness· 1 shared ingredient
Fibromyalgia is a real, frequently-dismissed condition affecting an estimated 2-4% of adults — predominantly women between 30 and 60. Its core features are chronic widespread musculoskeletal pain, fatigue, cognitive dysfunction (commonly called "fibro fog"), non-restorative sleep, and frequent comorbidities including IBS, anxiety, and depression. The dominant pathophysiologic model is central sensitization — the central nervous system amplifies pain signals — and a subset of patients also show small-fiber neuropathy on skin biopsy. Mitochondrial dysfunction and oxidative stress are increasingly documented in the fibromyalgia literature. CRITICAL: This protocol is ADJUNCTIVE. Fibromyalgia management is multi-modal, and supplements are one part of a larger plan. Conventional medications (duloxetine, pregabalin, amitriptyline, milnacipran), cognitive behavioral therapy adapted for fibromyalgia (CBT-FM), gentle aerobic exercise as tolerated, and aggressive sleep optimization all have stronger evidence individually than any supplement. That said, fibromyalgia is one of the few chronic pain conditions where supplements have notable trial backing — magnesium malate, CoQ10, vitamin D, and SAMe each have randomized data. If you haven''t had a rheumatology or pain-medicine evaluation, that should come first.
Travel Immunity Kit
travel· 1 shared ingredient
Air travel is an immune-compromise event: dry cabin air dries out mucous membranes, recirculated air increases viral exposure, sleep disruption suppresses immune function, and physical stress raises cortisol. The goal isn't "boost" immunity (a misleading framing) — it's correct any nutrient gaps that would otherwise dim the immune response, and reduce the severity and duration of any infection you do pick up. Vitamin D and zinc are the highest-leverage nutrients here. Vitamin C and quercetin have smaller, supportive roles. This is a 10-day protocol: start 3 days before travel and continue for 7 days after.
