About This Product.

Immune Charge+ Throat Spray is a sublingual and oropharyngeal spray from Quicksilver Scientific, combining zinc, elderberry, and echinacea in a format designed for rapid mucosal absorption. Sprays bypass the digestive tract and deliver actives directly to the tissues of the mouth and throat, where early-stage immune challenges often begin.

Zinc is central to normal immune cell function and is studied for its role in shortening the duration of upper respiratory symptoms, particularly when delivered close to the site of infection. Elderberry extract has a long history of use in supporting the immune response during seasonal illness. Echinacea is one of the most researched botanicals in this space, commonly used at the onset of cold symptoms or as short-term preventive support during high-exposure periods.

This spray suits people who want fast, targeted support at the first sign of a sore throat or cold, frequent travellers, those working in high-contact environments, or anyone who finds capsules inconvenient during illness. It fits naturally alongside a broader immunity protocol but works as a standalone first-response tool.

Quicksilver Scientific built their reputation on advanced delivery formats — the spray format here reflects their house focus on bioavailability. As with all zinc-containing products, it is worth noting that long-term high-dose zinc use can interfere with copper absorption, so this is best used as an acute or short-course supplement rather than a daily year-round staple.

Immune Charge+ Throat Spray

How to Take It

i.

Spray directly into the throat or under the tongue as needed, particularly at the onset of symptoms or before high-exposure situations. Follow the dosage guidance on the packaging. This product is best used as a short-course acute supplement rather than a continuous daily supplement.

Frequently Asked.

When should I use this spray?

It is best used at the first sign of a sore throat or cold, or before situations where you expect high exposure to illness — crowded transport, flights, or clinical environments. Echinacea and zinc are most studied for short-term, acute use rather than continuous daily supplementation.

How does a spray compare to a capsule for these ingredients?

A spray delivers actives directly to the mucosal lining of the mouth and throat, bypassing the digestive tract. For ingredients like zinc, this format may offer faster uptake and targets the site where many upper respiratory infections take hold.

Is it safe to use this every day long-term?

Short-term use is generally well-tolerated, but long-term high-dose zinc supplementation can deplete copper levels over time. Check the packaging for the recommended course length, and consult a clinician if you are considering daily use for more than a few weeks.

Can I take this alongside other supplements or medications?

Zinc can interact with certain antibiotics and medications if taken at the same time — spacing them by a couple of hours is usually advised. If you are on prescription medication or managing a chronic condition, check with your GP or pharmacist before adding this.

Who is this not suitable for?

Those who are pregnant, breastfeeding, immunocompromised, or taking immunosuppressant medications should consult a doctor before using echinacea-containing products. Echinacea is also not recommended for people with autoimmune conditions without medical supervision.

First thing I reach for now

5 months ago

Kept this in my bag all winter. The moment I feel that tell-tale scratch at the back of my throat, a couple of sprays and I'm on top of it before it develops into anything. Texture is fine, taste is vaguely herbal — not unpleasant. Really glad I found it.

Works fast

5 months ago

Used it at the first sign of a cold last month. Woke up with a sore throat, sprayed every few hours and by the next morning it had largely cleared. Can't say for certain it shortened things but the timing was convincing enough that I've ordered a second bottle.

Good product, wish the bottle lasted longer

5 months ago

Does seem to do the job — I used it through a rough patch at work when everyone around me was coming down with something and I stayed well. My only gripe is that if you're using it regularly at the onset of symptoms, the bottle runs out faster than you'd expect for £14.99. Feels like you're burning through it quickly.

Does what it says. Travel a lot for work and this lives in my carry-on now.

Swapped from lozenges and won't go back

6 months ago

I used to rely on zinc lozenges at the first sign of a cold but they're so harsh on an already sore throat. This spray is so much gentler to use and feels more targeted. I've noticed I'm getting through colds noticeably faster since switching, or at least I feel like I'm catching things earlier. Either way, I'm a convert.

Really like the concept and I do think it helped me kick a cold quicker last month. Only reason for 4 stars is the nozzle spray pattern is a bit wide — I end up getting it on my lips more than the back of my throat. Minor thing but worth noting.
