Your body has its built-in defense against disease, sickness, and ailments – the immune system. Health is impossible to achieve with a weak immune system. Sleep, age, diet, exercise all contribute to your ability to stay healthy and happy. Supplements are another way to help strengthen the immunity levels you carry with you every day.

The issue with the supplement is the amount of each ingredient on the list. Immunity 911 contains more components than any other on the list; it is also one of the most expensive. Elements used in PhytAge are in relatively low doses, likely making them ineffective at treating anything or helping with immunity-boosting power.
Many health nutritionists speculate the ineffectiveness of the low doses of ingredients like Green Tea leaf extract and Raspberry extracts. There is also no description of manufacturing standards, or ingredient sources, making it hard to trust Phytage.

Immunity Booster Ranking Standards
To compile the list, we considered many factors with our medical expertise. First, we looked at the list of ingredients on each and where they are backed by scientific research. We gave the supplement points if the ingredients listed were proven to improve the immune system, like Zinc. Following good practices and quality control, we also took into consideration where ingredients were sourced.
If there was no way to determine the quality or authenticity of the ingredients, we gave the supplement a lower ranking. Also, regarding quality- control, we checked on where each product was manufactured, and what standards they were held to.
Products manufactured in FDA-approved facilities, under Dr supervision, were naturally bumped up on the ranking chart. We dumped supplements without approved manufacturing standards or those not divulging information.
The effectiveness of ingredients in each product was looked at carefully, as were the dosages used. Any companies making unproven claims or essentially selling snake oils were not given the same respect as those that did, lowering them on the list.
Many supplements we looked at were removed outright from the list, as some made claims they could even prevent illnesses like Covid. There is no supporting evidence, any immune system support supplement can or does treat viruses like Covid-19. Many supplements making claims of this nature were made in countries with little to no regulations, so we did not include them on the list.
Essentially, that means medical professionals legitimately support them.
Companies who made the supplements on the list, who we supported, and you can tell by how we reviewed them, have a long history of creating health supplements that work. We predominantly only ranked companies with a proven track record and no bad reviews from a medical standpoint. Lastly, we ranked the supplements on the list by price and value. If the price was equivalent to usage value and effectiveness, we gave it a spot on the list.
Side Effects of Immunity Boosters

Vegetables, fruits, herbs, minerals, and nutrients can all have positive benefits to your immune function. Taking supplements alone is typically not enough; however, a healthy lifestyle and diet are also required for a boosted immune system.
Just the same, poor diet and lifestyle will naturally weaken your body’s natural immunity to viruses and pathogens. You must take all of this into consideration when thinking of your overall health. A doctor will be able to provide you with the most honest advice, following a physical to determine your personal health needs.
Now let us touch on ingredients found in immunity boosters.

Important Information on the Immune System
Your immune system lies in your body. Its primary function is to stop unwanted agents from entering your body. Your immune system is responsible for everything from tears, and sneezing, both the body’s first line of defense against pathogens, to producing antibodies that fight off infections. The immune system creates T-cells; they call into play antibodies to help fight infection or directly attack pathogens on their own.
The best vitamins you can take for immunity-boosting properties are Vitamins C, D, and E. Each of these vitamins is readily available from food, the sun, and supplements. They help your body’s innate ability to ward off disease and infection. Different organs also support the immune system, recognizing pathogens as they enter your body. It is therefore essential to keep your internal organs healthy. You can help your immune-oriented organs like the spleen and thymus by eating healthy fruits and greens.
Other factors proven to improve immune functionality include your weight, sleep habits, drug and alcohol use, and activity levels. Toxic substances are guaranteed to lower your immune system, as is heavy drug & alcohol use. Not sleeping weakens your immune system, as does lethargy. These are all factors that promote healthy immune response.
Basically, to stay healthy, eat healthy, sleep well, stay active, and take the right supplements. It all sounds simple but is not easy in the busy world we live in. Hopefully, this guide will help you keep a healthy immune system and thereby a higher quality of life.
