what percentage of Immunoglobulins ?

One thing to note is that immunoglobulins are only one factor to what makes colostrum amazing. Whole first milking colostrum can vary from 15% to 24% IgG (IgA, IgM, IgE, and IgD, are also found in colostrum). The only way to increase the IgG content is to boost it with bovine serum, or remove something else, typically thats it’s lipids. Adding in additional IgG’s pushes other important factors in colostrum out but removing its fats allow for more space. Additional IgG can fill some of this space but the fat that is removed is critical to colostrum’s protection through the digestive process. Colostrum is absorbed in the lower intestine so it needs protection from digestive enzymes. IgG content can be increased once the natural fats (lipids) are removed but it has to be treated with an aftermarket lipid to ensure it’s efficacy. Skimming colostrum and treating it with a liposomal spray has shown to be effective. TBR’s colostrum is a natural whole colostrum and their m.o. has always been “if it ain’t broke, don’t fix it”. A true balance of whole colostrum’s components, the way it was naturally designed, has been shown to offer the widest array of healthy benefits. Focusing just on immune health (the reason Immunoglobulins are important), means less focus on gut and organ health, improved skin, tendons, ligaments, increased lean muscle tissue, increased metabolism, better nutrient absorption, vitality, and other reasons that colostrum can benefit the body. Hope that’s helpful. Natural. First Milking. Pure.

Is this product from organic, grass-fed cows?

The label says antibiotic and hormone free. It doesn't specify that it's grass fed or organic. You might want to go to their website to know for sure. I can tell you that this is the best colostrum I have ever used so far. Of course I stopped trying brands after I had this one.

Our (gelatin) whole first milking colostrum is collected from hundreds of US Grade A Dairies and processed using the most gentle processes available to ensure untouched bioavailability and efficacy.

Made in laboratory/ pharmacy?? or natural farm please?

Sourced from U.S. grade a first day lactating dairy cows.

Have seen a huge difference!

Started on the colostrum approximately 5 months ago to help with chronic sinusitis. And yes, it helped me! I didn't even take the full days dose as recommended and I still saw results so quickly. Within a few days. So I continue to take it daily, when I wake up I drink some water first and then I typically take 1 capsule. On days that I need a bit more of a boost I will take 3 capsules. A few days ago I think the ragweed was affecting me in the evening, I was sneezing and had a runny nose. I took 6 late afternoon, and then a few more before bed. Next morning, no issues. I even convinced my mother she needed to try the colostrum, and she has never been one to take my advice on supplements. I sold her on it :) Thanks so much for this whole food, immune boosting, life giving supplement. You don't understand how much I appreciate the product. I have had chronic sinusitis with facial pain, headaches, ear pressure for past 4-5 years on a regular basis. Thanks so much!

life changing

About a year ago one of my friends told me about this product and how much it had helped her and her husband who were in their middle age to have way more energy and to feel better. I listen to her advice and OMG am I ever glad that I did! I am now growing all kinds of hair back. My hair had been thinning as I was going through middle age. I have so much energy now that I am waking up before my alarm clock goes off which in my life is unheard of! I cannot wait as I continue to take this product to see the changes that will come about with what I have already experienced. This product is amazing and I highly recommend it. My husband and I both take it and we are both noticing the differences!

Love this product !!

The capsules are a little hard for me to swallow. I empty them in a small bowl and eat with a spoon. Doesn’t taste bad and drink some water. I’m a type 2 diabetic and try to control without medication. It has lowered my morning fast down to 117 so far. My afternoon is down to 91. I am feeling more energy . I use this product morning and night before bedtime . A great bovine colostrum for a whole lot less money Thank you TBR Labs for your Great Bovine Colostrum.
