Shingles, also known as herpes zoster, is a painful skin rash caused by the reactivation of the varicella-zoster virus, the same virus responsible for chickenpox.
While it can affect anyone who has had chickenpox, shingles is more common in older adults and those with weakened immune systems.
Alongside antiviral medications prescribed by healthcare professionals, some people look to supplements for additional support.
Though no supplement can cure shingles, certain vitamins and natural remedies may help strengthen the immune system, reduce inflammation, and ease discomfort. Here’s a look at some of the most promising options.
1. Vitamin B12
Vitamin B12 is vital for nerve health, and a deficiency can worsen nerve-related pain. Some studies suggest that B12—especially in the form of methylcobalamin—may help relieve the nerve pain associated with shingles and postherpetic neuralgia (PHN), a common complication where pain lingers after the rash clears.
Suggested form: Methylcobalamin lozenges
Note: Always consult your GP before high-dose supplementation.
2. L-Lysine
L-Lysine is an amino acid that may help inhibit the replication of herpes viruses, including the one that causes shingles. It's thought to work best when taken at the earliest signs of an outbreak.
Suggested dosage: 1,000–3,000 mg daily (short-term use)
Caution: Long-term use can lead to amino acid imbalances—consult your healthcare provider.
3. Vitamin C
A powerful antioxidant, vitamin C supports immune function and helps combat viral infections. Some evidence suggests that high doses may shorten the duration of shingles and reduce the severity of symptoms.
Suggested dosage: 1,000–2,000 mg daily
Tip: Liposomal or buffered vitamin C may be gentler on the stomach.
4. Zinc
Zinc plays a crucial role in immune response. Low levels are associated with poor wound healing and increased susceptibility to infections. Supplementing with zinc during a shingles outbreak may help your body recover more quickly.
Suggested dosage: 20–40 mg daily for a short period
Note: Excessive zinc can interfere with copper absorption.
5. Lemon Balm (Melissa officinalis)
This calming herb has antiviral properties and can be applied topically or taken as a tea. Lemon balm creams may help soothe the rash and promote healing when used early.
How to use: Apply lemon balm cream to affected areas 2–3 times daily
Alternative: Drink lemon balm tea to support relaxation and immune health
6. Magnesium
Shingles can cause nerve pain that lingers long after the rash disappears. Magnesium supports nerve function and may ease nerve-related discomfort and muscle tension.
Suggested dosage: 200–400 mg daily (magnesium glycinate or citrate forms are well-absorbed)
Bonus: May also help improve sleep during an outbreak.
7. Probiotics
Stress and antiviral medication can disrupt the gut microbiome. A healthy gut supports immunity, and probiotics may help rebalance your digestive system during and after a shingles episode.
Suggested strains: Lactobacillus rhamnosus, Lactobacillus acidophilus, Bifidobacterium longum
A Word of Caution
Before starting any new supplement—especially if you're taking prescription medications or have underlying health conditions—consult your GP or a qualified nutritionist. Supplements can interact with drugs or be inappropriate for certain individuals.
Final Thoughts
Shingles can be a distressing and painful experience, but supporting your body with the right nutrition and supplements may help ease symptoms and promote recovery. Pair these natural aids with plenty of rest, hydration, and a gentle skincare routine to support your healing journey.
