We have no doubt at all about the quality and efficacy of Primal Immune Defense by Primal Harvest. It's a remarkable all-in-one immune support formula that helps maximize your body’s natural defenses.

Backed by scientific research, top-notch ingredients and the 90-day money-back guarantee on it, we are 100% confident in our #1 pick.
Besides aiding healthy immune system, Primal Immune Defense helps with digestion and improving general health. The capsules are extra small, making it easy to consume every single day.
You'll get a highly effective supplement that will supply your body with all the much-vaunted health benefits that Primal Immune Defense can offer. Plus, you can rest assured, the quality is ensured and backed by independent 3rd party lab tests.
Immune Defense's pricing stands out, especially when you buy multiple bottles. The price drops dramatically and since continued use over months is recommended to achieve the best benefits, buying a 3-6 month supply is a no-brainer.
There’s just a small thing: they get sold out really fast. So we recommend you hurry and place your order if you are now assured that this will be beneficial to your health.

What To Avoid:
Glorified vitamin C supplements
A supplement containing high dosages of just vitamin c is not ideal to boost a complex immune system.
Supplements with no probiotics
70-80% of immune cells live in your gut. Not addressing your gut health is a major oversight.
Unproven vitamins & minerals
It's always better to stick with a supplement containing well researched and scientifically proven ingredients instead of relying on marketing terms.
Extremely Low or High Price
Do your research before buying an overpriced or suspiciously cheap supplement. Do not cut corners for your immune health.
Key Ingredients To Look For
Considering your gut makes 70-80% of the cells in your immune system, probiotics are crucial for long term immune system. In particular LA-14 Lactobacillus Acidophilus probiotic has been heavily researched as the top immune-boosting strain.3
Probiotics
Has been used to fend off and reduce the duration of flu and common cold symptoms for years. Zinc is needed for immune cell development and communication and plays an important role in inflammatory response. We recommend a supplement with at least 20mg of Zinc.4
Zinc
Vitamin C
The classic Hero of Immunity. Vitamin C contributes to immune defense by supporting various cellular functions of both the innate and adaptive immune system. A good immune boosting supplement contains at least 300 mg of vitamin C.5
Vitamin D is essential for immune function. Healthy levels of this vitamin may help lower risk of respiratory infections. A good starting point of vitamin D3 is 1000 UI.6
Vitamin D
Vitamin B
B vitamins, including B12 and B6, are important for healthy immune response. Yet, many adults are deficient in them, which may negatively affect immune health.7
The idea of boosting your immune system is alluring, but the ability to do so has proven to be difficult for multiple reasons. The immune system is a system, not a single entity and there is no single solution. To function well, your immune system requires balance and harmony... in your gut.
Over 70% of your immune system’s cells are connected to your digestive tract1. Healing your gut is the first and most important step to protecting yourself against viruses and harmful bacteria.
Your intestines are home to roughly 10x more microorganisms than human cells in your entire body2. When balanced, your intestinal microflora (your gut) fights off harmful bacteria that cause illness. Daily supplementation with vitamins, minerals and probiotics is a great immunity-boosting tool!
