ProBoost does not only have to be taken at onset of symptoms to work. It healed a two-week-old flu.
Once a year, my mom usually comes down with the flu for two to three weeks. Unfortunately, she cannot get a yearly flu shot because of a previous severe allergic reaction to the vaccine. My mom is seventy-one and very healthy except for suffering from asthma even when she is well. As a result, the flu tends to infect her lungs with pleurisy, pneumonia, etc. At this point, she always has to take an antibiotic (500mg of Amoxicillin), which is poor for her both her digestive and immune system by killing all beneficial and bad bacteria. Sometimes, she can avoid taking a harmful antibiotic by immediately taking an Echinacea with goldenseal tincture, elderberry supplement and/or elderberry cough syrup, Boiron’s Coldcalm or Emergen-C when she first comes down with the flu. However, none of the above kept the flu from infecting her lungs this time. After two solid weeks of having the flu, she could not sleep for the severity of her coughing and wheezing and even the humidifier/vaporizer next to her bed did not help her breathe. Our family’s doctor was on vacation, so we would have to go to a walk-in clinic or the ER for help. I told my friend about my mom’s frightening illness and asked her to pray for my mom’s recovery. She generously gave me her box of Proboost Thymic Protein A with the instructions to dissolve one packet under the tongue three times a day for three days and then one packet per day for seven more days. At first, I worried that ProBoost may give my mom asthma because she reacts to certain medications. Thankfully, I decided to take a chance and gave my mom ProBoost as instructed and her lungs started improving within twenty-four hours with no asthma side effects. Within three days, she was breathing normally (no wheezing) and she was almost over the flu/infection within seven days of taking the first packet. Thank God, my kind friend, and ProBoost for healing my mom’s illness. It’s good to know that ProBoost is effective at healing an illness/infection that someone has had for a long period of time, and it does not only have to be taken at the onset of symptoms to be helpful (although taking it at the first onset of symptoms would be best). She completely healed from the flu and lung infection without taking antibiotics, and now I always keep a full box of ProBoost in our house.

Proboost is an amazing product, for anyone suffering with Adrenal flu like ...
Incredible company, very generous - when I noticed an extra supplement that I had not ordered and contacted them so I could pay for it, they gifted it to me which I will pay forward. Proboost is an amazing product, for anyone suffering with Adrenal flu like symptoms, this is what got me over the last hurdle in combo with my Naturopath Drs protocol, I discovered it in the book From Fatigued to Fantastic by Dr Jacob Teitelbaum, I also spoke with the creator of this product and he is the nicest man and truly dedicated to solving immune disorder issues, I am grateful for his brilliant work. Your body will tell you how much to take - it takes time to balance out a supplement regime and detoxing. Be patient as it can take months but thats ok, it took months/years to get depleted and it takes time to restore the engine but it will restore. Don't give up! Thank you Proboost and Tiger Health!

Supplement for FIP cat
My cat was diagnosed with FIP, which used to be a death sentence, but now there’s an off market drug (informally called GS) that treats the illness - it’s very expensive but has a very good cure rate. You can get the drug on Facebook under a site called FIP Warriors, and on that site, everyone recommends this supplement along with a pro-biotic and Denamarin. My vet is working with some of the researchers of GS who compile data across the world, and she recommends this. The company said to give 1/8 a teaspoon twice a day but many are giving 1/2 packet twice a day with no ill side effects. You mix it into their wet food. They should ONLY be getting wet food - dry food has many more chemicals that cause more inflammation in the body. My cat was given days to live but has now completed her 3 month treatment of GS so now we are in observation. Vet said to continue this supplement for next 3 months but we will probably continue it forever. Note that it wasn’t this supplement that cured her - it was the drug - but this supplement improves chances that the drug will work and lowers chance of remission.

I've changed my mind, if just a little bit
I initially rated this stuff a star lower, and complained that it didn't seem to do much if you were already ill. I think that this is still true, but I've tried it again, and it does seem to have a strong prophylactic effect; I've taken it before, during and after plane trips, office outbreaks and conventions, and I seem to be one of the lucky few who doesn't get sick if I keep up with it. It still makes me a little queasy when I take it though, and the cost is kind of insane, which is why I'm only giving it three stars out of five. I'd probably give it three and a half if I could. I would give it the full four if the cost was more reasonable.

chemical odor from the envelope
This is my first time buying this product in the envelope versus the box, and there is a very strong chemical smell coming from the envelope +/- the product. Why is that?

Go-to supplement
This has always been my go-to supplement if I feel any icky coming on. Hard to say without a control group, but I'm petty sure I get over whatever ails me at least 2 days quicker than if I hadn't taken it. Follow the direction, yes it's a little gritty and weird at first but you get used to it. I recommend taking a drink of water before to really wetten under your tongue and just pop your head back and drop it in there. Once you open the packet, fold the opening into a "V" makes it easier to get under the tongue and not all over your teeth. To me there is no flavor/slightly sweet bland flavor. Nothing overpowering at all. I have never had an upset stomach taking this. Will always have this in the medicine cabinet!

Recommended to include this into Kitty's treatment plan of FIP. He had 2 relapses so hopefully this will help this time round.
