Good Health Viralex - Everyday Immune Support has been formulated to support the immune system against viral, bacterial, fungal and parasitic infections. Viralex is designed to assist the body's defences and strengthen the immune response.

Key ingredients are Olive Leaf Extract, which studies show has a direct effect on immune system function; Beta Glucans to provide rapid immune support, and Astragalus and Zinc, together providing a potent tonic that will assist you in getting back on your feet sooner rather than later.

Research has shown that Olive Leaf Extract, in combination with zinc, may provide support against the discomfort associated with inflammed throats, tonsillitis and upper respiratory tract infections.

Good Health Viralex is a long-standing favourite of HealthPost staff and customers alike due to it's winning combination of value and effectiveness. We recommend Viralex as a basic, year round family wellness essential.

Keeping me healthy! Review by
  • star

I take one of these every day and up the dosage depending how I feel or if I'm around people with colds and coughs, and if prolonged exposure to unwell people I take the recommended acute dosage. My flat mates have both had really bad colds and coughs and I haven't! I would thoroughly recommend in winter months particularly just taking a maintenance dose to keep your immune system going and avoid those nasty bugs that are always flying around.

Great product Review by
  • star

I've been taking viralex for a year or two now. Prior to this I was pretty susceptible to colds but haven't had one since - whenever I think one's on the way I up the dose and it disappears. Excellent when travelling.

Have been buying it for years - When you feel a cold coming on dose up on viralex and it doesnt develop into anything! Or take regularly to ensure your immunity is all great!

Fantastic & tried product Review by
  • star

Fantastic product. With travelling between NZ & the UK and doing 3 winters in a row - this product was one oof the things that stopped me getting sick. It's great & I take it with me everywhere.

Olive leaf? Olive YES! Review by
  • star

These are now my staple supplement coming into winter. Since taking them almost 3-4 months ago I haven't picked up a sniffle/cold (which is a triumph as I usually get any bug which is going around). Trying to get my non-herbal husband to take them so that dreaded 'manflu' doesn't make an appearance this year! Highly recommended to everyone

Viralex for relief and prevention of flu, sore throats and colds Review by
  • star

We keep Viralex capsules always in our cupboard and take them at the first sign of a cold. They relieve the symptoms if we are already unwell and they hasten recovery. We also take them as a preventative before winter instead of a flu injection. We both have physical jobs and I work outdoors all year around.

Great Immune Support! Review by
  • star

My daughter has Ulcerative Colitis and with that has a very low immune system, if someone is sick within the household then by the next day she would catch it. However she has been taking these for over two years now and is hardly ever sick! Has made a huge improvement.

No winter flu for me!! Review by
  • star

I have used Viralex for the first time this autumn/winter and have remained very healthy despite being in close contact with people who are suffering with colds and flu bugs. If I DID feel like I might be coming down with something I'd have two capsules instead of my daily one, and I'd be fine!!!

Excellent Review by
  • star

This product is the bomb - started coming down with a cold, croaky voice, sore throat - began taking these (at double the dose for the first couple of days) and boom! - back to good health again
