Kept our kids healthy when they started to get sick!

Our kids started school and started to feel under the weather after just a couple days. We double downed on their ProBoost and they both were back to being 100% in no time. :)

A Great Product If You Have COVID

An easy-to-use product at a decent price. I prefer the ProBoost packets but make use of the orange tablets when I am on the go. Really helped me improve my immune response. I highly recommend ProBoost Thymic Protein A.

ProBoost For FIP Cats

I am treating my cat for FIP and I use ProBoost to help boost his immune system. His bloodwork had improved since using it.

So far so good

I use this for my cats, and it seems to help them quite a bit. Thank you!

Important part of my healthy lifestyle!

Just love everything about this product. I’m a boxing coach and a health “fanatic” and this is a big part of my health plan!

Seriously everyone needs this

I had gotten Covid and tried this product and man it turned me around! Within 24hrs I started feeling better.. one day I forgot to take it and I noticed the difference! I know they can’t claim anything for covid but I can! I have more energy , my stomach issues have gotten better and I feel an overall wellness . Now I don’t know if they have claimed this but I also notice I crave healthy foods ! I think having a balanced gut and body , you only want good things in it. My sugar cravings have dropped drastically too!
Love love love this product!

ProBoost 1 "Original Formula" Tablets

Too few tablets in too big a bottle

1 bottle comes with 30 tablets and still has enough room for 150 tablets. The manufacturer needs to put more tablets in the current oversized bottle or use smaller bottles for the 30.

Great asset.

This is a great product to have in my Arsenal for immunity boost and protection.

Amazing Natural Immune Support Supplement

It's important for me to stay healthy - my life has many demands and I cannot afford to get sick. Proboost is an easy way for me to stay healthy. 100% recommend this product.

I volunteer with an animal rescue organization and have been fostering two kittens with FIP. They recently completed their treatment and your supplement was recommended to help boost their immunity. Finally a supplement they will willing take!

Love your product !

ProBoost is amazing

This product has kept me safe from illness for the past year. I use it faithfully, wish it was in stores!

A Work in Progress

I used ProBoost in 2010 to help enhance my immune system. I restarted it a few weeks ago for continued immune system issues including a low suppressor cell count. Muscle testing shows that I need 2-3 packets per day. Time will tell if my T-helper and T-suppressor cell ratio will normalize with this product.

Help for my cat

My kitten had FIP and after 84 days of daily shots she is now taking ProBoost to help her immune system get stronger.

Absolutely love this product

I have taken this many times and got it from another provider. I love it

for cats

I use ProBoost to support for cats. It's very strong and help them very well. Recommended!

Great but side effects too much for me.

Proboost helped the sinus infection I had quickly but I developed something like bad IBS, which I have never had. It was so effective with the infection however, that I would recommend giving it a try, hoping you won’t get the side effects.

ProBoost 1 "Original Formula" Tablets

Hoping for improved white blood cell including T-cell numbers.

I'm an HIV positive person (since 1997) who has had pretty much low T-cell counts and more recently (two years) a cancer including surgery, radiation and chemotherapy thriver who has been experiencing very low and very stubborn WBC counts. I started taking ProBoost Thymic Protein A with hopes of improving those counts. Will be getting a blood draw in a couple of weeks. Thanks ProBoost for being here!
