Is your whey certified organic?

All Promix products are non-gmo and gluten-free, but our whey protein is not certified organic, as you noted.  We fully support organic farming and practices, but if our whey protein was certified organic the price would be well over $100/container, and we have opted to keep our cost lower for consumers.  We believe that we provide the best cost-effective, clean protein powder out there. Promix whey is sourced from farms with 100% grass fed cows, and the cows graze on fields that have always been grazing fields, and have never been used commercially for crops or with any pesticides!  Our processing is free of any industrial solvents or irradiation, and all of our products are third party tested for heavy metals, gluten and other additives/contaminants!

The vanilla extract from Indonesia, this does not state GMO free so it is not gmo free?

All of our products, including our Vanilla Whey and the Vanilla extract used, are 100% non-gmo!

Do you ship to Canada?

Yes we do. However, at this time, not all Promix products are available outside of the US.

Why are there fewer servings in the same size of Chocolate flavored whey compared to the unflavored?

I apologize for any confusion!  The reason for the difference is that we wanted to have the same amount of protein per serving in both products and therefore, to account for the added ingredients and blend of the chocolate whey, we had to make the chocolate whey a larger serving size, which means there are fewer servings in the 5lb tub of the chocolate than in the same size unflavored container.

How much lactoferrin, immunoglobulin and serum albumin is present in Promix whey?

Typical values of each of lactoferrin, immunoglobulin and serum albumin present in one serving of Promix unflavored whey concentrate are listed below: 

  • Lactoferrin: 0.125 grams - 0.3 grams
  • Immunoglobulin: 1.75 grams - 2.25 grams
  • Serum albumin: 0.75 grams - 1.25 grams 

Do you offer international shipping?

We are just beginning to offer some of our best selling products in Canada, UK and EU. We hope to offer more items in the near future.

Are you able to ship to P.O. boxes?

Yes, we are able to ship anywhere in the U.S., including P.O. boxes!

How long does it usually take for my order to arrive?

With our free standard shipping, typically, orders ship within 24-48 hours and arrive within 5-7 business days!

Do you test for vitamin/mineral levels after processing?

The vitamin levels listed on our nutritional panel are the final vitamin/mineral levels in the product as packaged!

Looking at the amino profile - are any of these aminos added in?

All the amino acids present in the whey protein are naturally occurring, and they are not added in from other protein sources!

Can I mix Promix into my morning coffee?

As a general rule, our Promix whey mixes best with cold liquids, so we would not recommend mixing it with hot coffee.  If you are looking for a product to add protein to your morning coffee, our collagen product was specifically designed to blend seamlessly into hot beverages like coffee, so we would recommend that!

For baked goods, can I mix the powder in with the other dry ingredients and then add the fluids as directed or must I mix it in with the fluids required in the recipes before adding the dry ingredients? Will the protein benefit be lost in baking?

Lots of our customers have used our products to incorporate in baking recipes, and the protein benefit is not lost in baking.  As to specific directions, it depends on the recipe, but there are no set rules as to when to incorporate the protein powder.  If you come up with some great recipes, we'd love to hear about them!

Where are the cows raised that you get your whey from?

We source our whey from small farms in Northern California, specifically in the Humboldt and Del Norte Counties.

Do you offer samples of your product to try before purchasing the 5lb size?

We are working on restocking our single serving samples and sample packs.  Once they are ready they will be available for purchase on our website and on Amazon!  Thank you!

Why is your collagen from Brazilian cows? Why not from USA cows?

All of our grass-fed whey protein and casein are USA sourced from small, family farms. Other ingredients are sourced globally, wherever we can find the best quality, non-GMO, hormone-free ingredients, such as our grass-fed collagen peptides from Brazil. We think that these are the best quality out there for the product, as the cattle industry in Brazil relies on perennial tropical grass pasture systems and hormone use is banned.  Thank you!

My product arrive damaged, what can I do?

If you ever have any issues with your order, please let us know!  We strive for 100% customer satisfaction, so if you aren't completely satisfied, we will do what we can to fix it, including arranging returns, exchanges and refunds.  Just email us and we will make it right!

What would the Protein Puffs do in a blender - are they easily softened and mixed, or would you recommend against it?

Our protein puffs are really designed to add a tasty crunch to things like baked goods, parfaits, and on top of smoothie bowls.  While putting them in a blender isn't necessarily a bad idea, this would definitely soften them, but wouldn't necessarily provide the consistency one looks for in a protein smoothie, so we would recommend our protein powders over the puffs if you're planning to use your blender!

Is Promix rGBH free and is it from A1 or A2 cows?

All of our products are hormone free.  We source our whey from A2 Jersey breed cows, and we are working with a California university on hair sample testing so we can provide documentation on A2. Please email us if you have any other questions!

On the Dr. Axe site he said isolate and hydrosalate can cause leaky gut because of the way they are broken down and the fillers/ artificial flavors and stuff.  Is this true?

We certainly don't disagree that certain sweeteners, artificial flavors, colors, gums, or other fillers may contribute to leaky gut.  No Promix product contains any of the above, and no enzymes are used in the processing of our whey isolate, only mesh filters (cold-processed micro-filtration).  I believe Dr. Axe's comments apply to those other brands using the above additives, etc. or other processes besides cold process microfiltration.  Thanks!

Your whey looks great; you say it is cold processed - does that mean it's unpasteurized?

Our cold-processed microfiltration is a technical term to describe the liquid whey being filtered through mesh filters to help concentrate the whey particles. This is a cold process filtration because this is all completed with pressure of flow rather than any heat.  As to pasteurization, there are false claims by other companies about raw whey or whey that has not been heated. FDA guidelines actually mandate that the milk that all whey is made from be pasteurized per FDA pasteurization guidelines prior to it being made into whey.  Hope this helps!

 Is the amino acid distribution and amount of bound protein vs. free amino acids per serving verified by third party testing?

Yes, all of the nutritional values of our products are verified by independent third party testing!

Who does your third party testing?

We work primarily with Eurofins and Covance, and others depending on the testing done.

Do you offer a vegan mix that also contains hemp protein?

At this time, we only produce our one vegan mix (both unflavored and chocolate), which is a blend of organic pea and rice protein.  We do not currently offer a hemp protein, but we are always considering new products!

What is your Maltodextrin derived from?

Hello Timothy, the maltodextrin is derived from 100% organic tapioca (corn and gluten free). Thank you

Is this product corn and gluten free?

Hello Nicolette, yes, ProMix is corn-free and third-party verified gluten-free. Thank you

how come there are 18 more servings per bag of the unflavored version?

Hello Josh, thank you for your question. William is correct. We wanted to have the same amount of protein per serving in both products and therefore had to make the chocolate version a larger serving size. Larger serving size means fewer servings per bag (both bags are 5 lbs). Please email us if you have any other questions. Thank you!

Is this Cold processed and or raw unpasteurized whey?

Hello JM, thank you for your question. All whey protein sold is required by the FDA to be pasteurized. Our filtration process after pasteurization is cold-processed microfiltration. Thank you.

curious about why there is evaporated cane juice in this product.

Hello WildDandelion, the evaporated cane juice is added because it helps to round out the flavor of the raw cacao. Raw cacao on its own is relatively bitter. Thank you!

How many servings (1 scoop) are there in the 5 lb bag?

Hello Alexander, there are 146 (1 scoop servings in bag). We recommend 2 scoops per serving (73 servings per bag). Thank you

I recently received a bag of your chocolate flavor. Why does it no longer say "Third Party indpendent testing" on the back?

Hello Dan, thank you for your message. The bag should state "Third Party Indepent Testing" on the back label in the check mark section. If the label does not it was an error in the label layout and printing. Our Third Party results are listed on our website and you may also email us for more detailed results. We are transitioning to a new rigid container to solve the issue customers have had with damaged or hard to seal bags. Thank you again

Who has etsablished nutrition data profile for the protein powder ? How amino acid and protein context was determined ?

Production samples of the whey protein are submitted to an independent lab for nutritional analysis, including amino acid content. Thank you for your question.

How much cholesterol in the product?

Hello Konstantinos, thank you for your question. There are 15mg per 25 grams serving. If you have further questions please email us at sales@promixnutrition.com

Heavy Metals Testing. Does anyone know if the END PRODUCT (not ingredents, since it's processing that adds heavy metals) have been tested?

Hello BlueWallpaper, The heavy metals testing is done on the finished product, not the ingredients before they are combined.

is the grass that the cows eat treated with pesticides?

Hello amt23, thank you for your question. There are no pesticides used on the pastures. The pastures are used exclusively for cattle year round. There is no crop planted on the pasture land where pesticides may be considered for use. If you have any further questions please email us at info@promixnutrition.com. Thank you.

Can any speak about this product vs. Vital Whey? Vital Whey appears very high quality and this seems comparable at half the price. Thanks

Hello, thank you for your question. ProMix Nutrition works directly with the whey production from the milk of pasture based cows in northern California. We believe we price our products fairly so that if people want to make the choice to buy a better whey it is accesible to them as a regular use product. Many whey companies purchase from outside the US through third parties so their costs are higher, combined with their advertising spend, translate to a much higher priced product for the consumer. We believe ProMix Whey is the best US based pasture based whey protein.

is this packaged in the USA?

Hello E.L., thank you for your question. Yes the ProMix Grass-Fed Whey is sourced and packaged in the USA.

My bag did not come with a scoop so please advise how much a scoop is equivalent to. (What size is the scoop)

There are a little over 5 tablespoons per serving (2 scoops). If you use a fork to fish around in the bag, you should be able to find the scoop. It tends to shift during transit.

Does this 5 pound sack need to be refrigerated?

Hello. ProMix does not need to be refrigerated but we do recommend keeping it in an airtight container (the bag counts), and in a cool place like a pantry or cupboard.

Is there any Corn in this product or Corn fed to the cows at any point?

Hello Praveen, thank you for your question. The cows graze on grass and other pasture grasses. If the cows are indoors they eat harvested pasture grasses (hay). We researched milk testing to provide evidence there is no trace of corn in the milk. To our knowledge there is no currently available testing methodology for corn in milk. Please email us at info@promixnutrition.com if you have any further questions. Thank you.

How do we know it is really Hormone, Antibiotic free ? it's website is so brief no detail ... !

Hello Plus, thank you for your question. All the dairies we work with sign affidavits and contracts that no synthetic hormones or antibiotics have been used on their cows. FDA regulations do not allow any antibiotics to be present in milk. Each batch of milk is tested for antibiotics before accepting as part of the manufacturing plants HACCP plan. Control samples are used to insure the testing equipment is working correctly and the records are monitored by state and federal agencies. If you have further questions please email sales@promixnutrition.com

Does anyone know if this is low temp pasteurized? There is hardly any information on their website. Thanks!

ProMix is low-temperature pasteurized at 164 degrees Fahrenheit for 17 seconds. Please let us know if you have any other questions at info@promixnutrition.com

Is this Whey from 100% Grass Fed Cows?

Thank you for your question. The whey is derived from the milk of grass/pasture fed cows. The cows are on pasture an average of 330 days per year. When the weather is bad the cows will eat harvested grasses (hay) from the same fields they graze in. If you have any other questions please feel free to email us at info@promixnutrition.com. Thank you.

Are the cows 100% grass fed only? Many "grass fed cows" are rotated back and forth from corn and grass and they can still legally claim "grass fed"

Hello Caryn, thank you for your question. The farmers we work with have their cows on pasture 320+ per year due to the fact the weather and field conditions permit this. There are no ferilizer or pesticides used on the fields because the fields are exclusively used for grazing cattle, pasture land does not benefit from fertilizer or pesticides. When not on pasture the cows are fed hay harvested from the same fields they graze on.

Second purchase and the color is distinctly more yellow. What would be the reason?

Hello Craig. ProMix does not apply any chemicals or bleach to its whey and this sometimes leads to a darker whey than most people are used to. This completely depends on the batch of milk, but there is no need to be alarmed. ProMix prides itself on using ingredients that have been minimally processed.

what makes it instantized?

Instantized means that a lecithin has been added. In ProMix's case, a non-gmo sunflower lecithin has been used to make the protein more soluble in liquids.

Why is this product so much cheaper than other grass fed whey protein options I've come across?

Hi Paul. The reason is because we sell direct to consumers. Without all the middlemen, we can afford to get great grass-fed whey protein to you at a great price.

What farms specifically do you source your whey from ?

Hello. We get our whey from family farms in California.
