Give your immune system what it needs to respond the right way: Smart, balanced, and effective.
When encountering a problem or threat, first responders are critical for keeping us healthy and protected.
And did you know?... You have your own internal team of first responders!
Antibodies (otherwise known as, “immunoglobulins”) get immediately deployed by your immune system when a bad guy pops up on the radar.
Enter Ultimate IgG – The break- through new stress management and mood support formula.These health champions race out into your body to identify, bind to, and promptly show any unwanted guests the door.
Under ideal conditions, you have lots of first responders on call – Especially Immunoglobulin G (IgG).
(IgG is the most crucial member of your response team, and makes up almost 80% of your total immune protection system!)
However, in times of high stress, or when your system gets slowed by something unfamiliar, your production of IgG can dwindle...
And that can quickly result in bad guys barging through your door and overwhelming your body.
Nobody wants that... Especially these days....
That’s why we created Just Thrive Ultimate IgG.
The easy-to-take capsules work to rapidly support your body’s IgG levels.
That means more immunoglobulin first responders where and when you need them most!
Every capsule of Ultimate IgG:
As you’re well aware…
Between lack of sleep, processed foods, pesticides and environmental toxins, there’s no shortage of unwanted guests knocking on your club door.
But when you support your body with Ultimate IgG, you can feel confidently “at the ready,” and give your immune system the upper hand!

1. Healthy & Balanced Immune Power
To stay well, the last thing you want is an immune response that’s either too weak (leaving you vulnerable) or too strong (which causes more harm than good). Ultimate IgG helps your immune system respond the right way: Smart, balanced, and effective.
2. Maximum Antibody Potency
Ultimate IgG’s highly concentrated formula contains more antibodies than any other product on the market, and about 3x more than Colostrum’s 12-18% potency. This also makes Ultimate IgG THE most cost-effective product in the antibody-based category.
3. 100% Dairy-Free Formula
Most IgG products are made from milk, which can cause low-grade inflammation in the body. All antibodies in Ultimate IgG are conscientiously extracted from bovine serum, NOT cow’s milk, and found to be 100% free of lactose, casein and B-lactoglobulin.
4. Evidence-based & Safe
Many published clinical studies conducted over multiple decades show that the IgG antibodies found in Ultimate IgG to be well tolerated by highly sensitive individuals and provide significant benefit to the immune
Boosting your immune system is a bad move.
Yes, we know… Everywhere you look these days, you’re being told that boosted immunity is the only way you’ll stand a fighting chance out there…
But here’s what you need to know:
A “boosted” immune response – one that’s constantly in “fight” mode – can actually cause WAY more harm than good...
Allergies, autoimmune disease, cytokine storms (aka: excessive inflammatory responses)...
These are all examples of an immune system stuck in the “on” position, attacking the body, often with devastating consequences.
Here’s the truth:
A truly healthy immune system is not fighting every minute.
Instead it seeks balance...
First determining what not to react to…
So that when the real threats knock at our door, it can mount an appropriate response.
Though not widely known, antibody proteins known as immunoglobulins are the key players that help your immune system maintain balance.
Once sorted, they “tag” the true threats, and then move quickly to bind to and usher them out of your body.
And after an encounter, a small number of these immune cells remain in your system as threat-identifying memory cells.
That way, the next time your body encounters a similar attack, it can mount an appropriate response before anything gets a chance to take hold.
But here’s the thing about immunoglobulins:
In times of high stress or when slowed down by something new and unfamiliar, your production can be greatly impacted.
And that can spell bad news for your immune function.
This is where smart immunoglobulin support can work wonders for your ability to stay healthy and strong.
Your body’s most important Immunoglobulin soldiers are called IgG (Immunoglobulin G.)
They account for almost 80% of your bad guy-fighting power, and offer highly specialized protection for your gut (where some of the worst invaders try to attack.)
When your immune system malfunctions, it’s typically the result of your body’s inability to create enough IgG.
Low levels can leave you vulnerable, AND, they can make you more prone to immune overreactions.
But did you know?
When your body’s own IgG supplies run low, you can replenish them with special immunoglobulin supplements.
This can be incredibly powerful when you’re feeling run down, or if you just want a proactive lift.
But there’s one important caveat about IgG…
A helpful IgG product should be lactose-free so your body can tolerate it with ease…
Like Just Thrive’s Ultimate IgG which is 100% derived from bovine serum!
Conscientiously extracting immunoglobulins from serum ensures the product is free of lactose, casein, and β-lactoglobulin (the most abundant whey protein in milk.)
In this way, you get a fresh supply of IgG to support an immune system that responds the right way: Smart, balanced, and effective.
