Is Immun’Âge safe?

Many studies conducted all over the world by renowned scientists show that Immun’Âge® is not associated with any side effects, and presents no risks.

In 25 years more than ten million Immun’Âge packets were sold without any report on safety-related problems.

What about sugar ? / I am suffering from type 2 diabetes…

Immun'Âge® is a safe and effective choice, even for individuals with diabetes. Each packet of Immun’Âge® contains less than 1% of the daily carbohydrates needed by the average person, making it an easy addition to your daily routine without impacting your carbohydrate intake.

We have conducted thorough research on how Immun'Âge® affects blood and urine glucose levels in diabetic patients. The results showed no significant changes, confirming its suitability for individuals monitoring their blood sugar levels.

Does oral supplementation of a fermented papaya preparation correct respiratory burst function of innate immune cells in type 2 diabetes mellitus patients?

What is the difference between fresh papaya and fermented papaya?

  • Fresh papaya contains, among others, vitamin A and C, along with papain, a digestive enzyme that is found in the latex (between the bark and the pulp of the fruit).
  • The fermentation process to produce FPP® eliminates these vitamins. FPP® doesn’t contain papain either because it is made with only the pulp of the fruit.
  • Fermentation causes a modification of the constituents of fresh papaya, which results in 2 distinct foods, both in their composition and properties.

What action does fermented papaya have on my immune system?

With age, the immune system is less effective, oxidative stress increases and the production of cellular energy (ATP) decreases.

When it comes to the immune system, Immun'Âge stimulates immunity by activating macrophages, NK cells (Natural Killer) and the production of NO (Nitric Oxide) which are used for immune defence.

How does fermented papaya helps my antioxidative system?

Regarding the antioxidant system, Immun'Âge stimulates the main endogenous antioxidative enzymes: superoxide dismutase (SOD, main antioxidative enzyme in the body), glutathione peroxidase, catalase...; making your whole antioxidative system work better from within.

Immun'Âge also allows, to a lesser extent, to directly capture free radicals (measured thanks to observation by ESR = allowing us to see the capture of free radicals).

How does fermented papaya affects my cellular energy production?

Over the years, the production of cellular energy (ATP) decreases in your body.

Concerning the production of cellular energy, Immun'Âge makes it possible to stimulate the production of ATP at the cellular level (via the Krebs cycle): the sugars contained in Immun'Âge enter the cell without the need for insulin and make it possible to produce ATP (an energy unit molecule derived from sugars).

Are there any side effects from taking Immun’Âge?

After more than 25 years of commercialization worldwide, no side effect has ever been reported.

I am taking medication: Is there any drug interactions?

Immun’Âge is an all natural dietary supplement. There is no known or reported drug interaction to this day.

Are there any food, vitamins, or other supplements that I should avoid while taking Immun’Âge?

No. Immun'Âge is an all-natural dietary supplement. There is no known or reported interaction to this day.

What is the best time to take Immun’Âge?

It is best to take Immun’Âge on an empty stomach. Taking it first thing in the morning or just before going to bed are the best times.

Do not eat or drink anything within five minutes of taking Immun’Âge.

Can I take Immun’Âge daily?

Many people do take Immun’Âge daily. Intake may vary depending on your condition, your needs and your response to the product.

The standard daily intake for an average healthy person for general health maintenance is one packet per day. (One box of Immun’Âge Classic contains 30 packets of 3 grams each.)

Are there any precautions or warnings I should know about? Is there an amount or "upper limit" I should not go over?

Immun’Âge has undergone analysis and tests to confirm and validate its harmlessness for human consumption.

Do not hesitate to contact us for more details.

Are there any ways I can make taking Immun’Âge more effective? For example, does it work better with multi-vitamins?

Immun’Âge is effective by itself.

We recommend letting Immun’Âge dissolve under the tongue long enough to mix well it with saliva. Immun’Âge reacts with saliva improving its efficiency.

Is Immun’Âge a stimulant like vitamin C?

No, Immun’Âge is not a vitamin supplement and does not work as such: it doesn’t help restore a vitamin deficiency. It has a much deeper physiological effect on our defense systems and cell’s energy production.

Immun'Âge restores the balance between oxidants and anti-oxidants by ridding the body of excess free radicals and boosting cellular metabolism. 

Does Immun’Âge contain any gluten?

No, Immun’Âge is gluten-free

Can I use Immun'Âge with an anticoagulant treatment?

Immun'Âge doesn’t interfere with blood coagulation, and people under anticoagulant treatment (Simtrom, Previscan) have not reported any problem.

Coagulation parameters can change when people under anticoagulant treatment change their diet. Adding Immun'Âge® to their diet will generate a small change in their parameters, without usually creating any problem. While we never faced such a change, it still could happen.

Since people under anticoagulant treatment have to watch their level of INR (International Normalized Ratio) of Prothrombin time measurement, they have to adapt their anticoagulant treatment if there is a real modification while taking Immun'Âge.

Note: Two similar consecutive INR measurements showing modification show a real modification.

I suffer from electro-hypersensitivity (EHS or EMFIS)…

Immun’Âge helps relieve the symptoms for people suffering from electro-sensitivity. It helps them recover a normal brain perfusion and reduce some of the clinical symptoms (tachycardia, fatigue…)

I have an allergy to yeast…

Immun'Âge's fermentation is done using specific traditional yeasts (Saccharomyces), and after several months of fermentation, there are no living yeasts and identifiable yeast products anymore in Immun'Âge.

Over the past 25 years, people with yeast allergy did not encounter any problems while taking Immun'Âge.

However, since Immun'Âge's main components are carbohydrates (more specifically beta-glucans-like products) and amino acids, which are part of our cells components, allergy could occur, even if the risk is very low.

If you know that you have an allergy to yeast, we recommend testing Immun’Âge by taking half a packet to detect any possible allergic reactions.

I am scheduled for surgery. Should I be concerned about taking Immun'Âge?

Talk to your health provider.

I am pregnant…

We have not carried out any specific study targeting pregnant women taking Immun’Âge.

However, in more than twenty years of research, there has been no report on side effect or toxicity of our product, even on women taking Immun’Âge during their pregnancy.

If you are pregnant, consult your doctor before taking Immun'Âge.

Can children take Immun'Âge?

Immun'Âge can be used for children as a dietary supplement even in the case of recurrent ear, nose and throat infections commonly treated with antibiotics, but it should not replace any medical treatment. 
Consulting your doctor is highly recommended for such infections. 

  • Children under one year of age (after weaning): Dilute half a packet in mineral water or milk, 2 to 3 times a week.
  • Children up to six years: Place half a packet under the tongue once a day.
  • Children over six years: Place one packet under the tongue once a day

My skin is aging…

Immun’Âge helps slow down skin aging effects by improving the skin antioxidative capacity. Also, it helps improve skin moisturization, elasticity, and skin evenness.

Immun'Âge could have a beneficial effect on skin aging as it does in any condition triggered by oxidative stress (excessive amount of free radicals). Skin aging is partly due to free radicals attacking cell membranes, which leads to wrinkling.
See Scientific References.

I am undergoing chemotherapy or radiotherapy…

Patients undergoing chemotherapy or radiotherapy can take Immun'Âge before and after their treatment, but not during the treatment.

You can use Immun'Âge as a supplement taking two packets a day for two weeks before your treatment starts. 

During chemotherapy, do NOT take Immun'Âge because your treatment generates an intense oxidative stress to “attack” and eventually destroy cancerous cells. After your chemotherapy treatment is over, you can use Immun'Âge as a supplement to recover faster.

We recommend taking three packets a day for the first week after chemotherapy, two packets a day the second week. Depending on your age and level of oxidative stress, you may continue taking one packet a day.

If you have difficulties swallowing and lack saliva, dissolve Immun'Âge in a glass of water.
See Scientific References.

I am HIV positive...

Immun'Âge antioxidant qualities make it a good dietary supplement to add to your diet.

However, we recommend consulting your doctor before taking Immun'Âge.

I have bronchial asthma...

No specific studies have been dedicated yet to the use Immun'Âge with asthma.

However, as Immun'Âge does fight oxidative stress, it can be an adequate supplement if you have bronchial asthma, but it should not replace the medication your doctor has prescribed.

We recommend consulting your doctor before using Immun'Âge.

I have Alzheimer’s disease…

The antioxidative properties of Immun’Âge can be useful in helping to counteract the excessive production of free radicals (oxidative stress) present in people with Alzheimer’s.
