The Amazing Benefits of Your “Pacman” Antibody Proteins (And Why They’re Essential For Immune Health)

Everyday your body gets bombarded by viruses and infectious bacteria looking for a way in. 

Maybe your child/germ magnet brought something contagious home from school… maybe the lady sneezing and coughing in line at the grocery store blasted you… Or maybe you came into contact with whatever’s going around while going for a quick walk outside…

If your body didn’t have a natural, built-in self-defense system in place, you’d likely catch everything and feel sick all the time. 

But what if you could sail through cold and flu season without so much as a sniffle? Or navigate a plane ride and a business conference without the sneezy, achy fallout afterward? Or stay strong and well the next time your kid brings home the stomach virus du jour.

It’s possible to enjoy all these abundant health benefits… if your immune system is in the best possible shape.

That’s why you want to make sure your immune defense team – especially your army of germ-beating antibodies – is in top-notch fighting form.

Your Body’s Best Defenders: Antibodies

Antibodies are powerful, Y-shaped proteins created by your immune system to patrol for infectious microbes called antigens. (1) That nature-made Y-shape helps them latch on to antigens and quickly neutralize them before they can take you down. (2)

Common antigens include:

  • Bacteria
  • Viruses
  • Yeasts
  • Fungi
  • Allergens 

Any time your immune system senses an antigen, it sends out its best antibody soldiers to fight. The most crucial and plentiful defenders are special antibodies known as Immunoglobulin G, or “IgG” for sure. IgG antibodies are so important that they make up nearly 80% of your total germ-busting squad. (3)

Whenever IgG antibodies catch an antigen, they bind to it so it can’t escape. And once that antigen has been captured, IgG defuses the antigen’s harmful potential so it can’t cause any trouble. (4) Finally, IgG shuttles that antigen out of your body before it has a chance to trigger:

  • Inflammation
  • Infection
  • Intestinal distress

So long as your immune system is in top shape and producing plenty of IgG, you’ll be able to face each day head on and feel your best. 

As a bonus, IgG also lets your immune system know when it shouldn’t attack and helps keep it from overreacting. This is crucial because some of the worst damage you and I sustain happens when our immune systems don’t know when to turn off. IgG helps to regulate the immune response and prevent it from getting out of control.


If your immune system is overwhelmed or overloaded, which can happen if you’re saddled with too much stress or falling behind on your sleep or diet, your army of IgG antibodies may need reinforcements.

How To Know If Your Antibodies Need Backup

When your body isn’t producing enough IgG to keep you healthy, you run the risk of taking more “personal days” more often.

And when that’s the case, you’ll feel it. Signs that your IgG antibodies are running low and need some backup include: (5, 6)

  • Feeling run down or just “off”
  • Catching the same things over and over
  • Lots of digestive issues (gas, bloat, diarrhea)
  • Fatigue and grogginess
  • Trouble concentrating
  • Brain fog

No one wants to be slowed down or get sick… Especially these days! 

Thankfully, if your natural IgG supplies seem like they’re running low, you can send in reinforcements. (7)

Immune System Magic in a Bottle

Supplementing with clinically proven immunoglobulin “reinforcement” supplements can be a game changer when it comes to your immune health…

In fact, a mountain of research proves that these IgG supplements can deliver welcome and sustainable health benefits. (8)

Studies show that the right IgG supplement can help:

  • Support strong immune function (9)
  • Promote gastrointestinal health
  • Improve digestion (10)
  • Manage healthy inflammation responses in the gut (11)
  • Neutralize toxins and antigens (12)

With all that support on hand, your immune system can focus on what’s really important: Keeping you healthy all day, every day.
