We recommend that TAHA Health & Nutrition products are kept in a cool, dark place away from direct sunlight (i.e. your pantry!), and ideally are stored at temperatures not exceeding 25c/77F. However, we have not seen any issues where temperature has impacted the product quality to date.

TAHA WPI is manufactured using the ion exchange process that selectively isolates specific protein components, allowing other elements (carbohydrates, fats, and minerals) to be removed, resulting in a purer, higher protein finished product. Basically, the Ion Exchange process means that liquid whey is sent through a column that collects the proteins and separates them based on differences in their net charge. The rest of the molecules (lactose and minerals) are removed and further processed into different products.  Ion exchange allows the selection and retention of all functional and nutritional proteins in whey, including bioactive proteins such as immunoglobulins and lactoferrin, meaning more of the “good” is kept inside the product. The product then goes through a cold process ultrafiltration step to concentrate the proteins and is then evaporated and dried to create the purest protein on the planet!

All TAHA products are tested for food safety parameters (chemical, microbiological and physical) at the following locations:

1. The ingredient manufacturer – dairy proteins, flavors, and other ingredients that are blended together to create the final product
2. The co-manufacturer who blends the above ingredients and packages the protein powder under our TAHA brand

We also complete additional testing at:

1. 3P Laboratories who run the nutritional analysis on certain batches of product to ensure that they meet the nutritional facts panel data
2. 3P Laboratories who test for Glyphosate residue for The Detox Project.

Yes, the mono and di-glycerides in our product are plant-derived.

Yes our dairy protein is tested for Heavy Metals via a national testing program New Zealand and also periodically tested in independent labs in New Zealand and in the US.

Below is further information on the New Zealand testing program:

New Zealand's raw milk supply is monitored through the National Chemical Contaminants Program (NCCP), operated by New Zealand's Ministry for Primary Industries (MPI). The program has been effective in confirming that dairy products are free of chemical residues at levels that could pose a threat to human health or to international trade. NCCP testing has shown that raw milk is very low in heavy metal contaminants and provide assurance that the entire NZ Dairy Industry being free of harmful levels of heavy metals.

Our dairy protein is periodically tested by IANZ accredited external laboratories for heavy metals and other elements of interest. Our products have shown to be very low in these contaminants. TAHA Health & Nutrition confirms that no heavy metals are added to products and any levels detected are naturally occurring in milk.

It’s a question we get asked quite a lot….and the answer is “it depends”. Other than rare sources of raw milk (e.g. raw milk cheese) that aren’t relevant to TAHA Health & Nutrition products, all commercially available milk and dairy products in the USA are heat-treated for food safety reasons. This process is called pasteurization, where milk is briefly heated to 161°F for 15 seconds to remove harmful bacteria. Food law also requires milk and dairy products to be pasteurized before being exported from New Zealand.

Pasteurization is a heat step, but it has very little impact on milk proteins, and all major milk proteins remain in their original/native state. Our supplier of whey proteins has a variety of ingredients specially designed and processed for optimal nutrition and functionality in the finished products you receive.

For ready-to-mix powders, the processing is as gentle and cool as possible to ensure optimal solubility, so you can enjoy a smooth shake. On the other hand, whey protein for nutrition bars undergoes higher heat processing to create a more enjoyable texture. Despite this, the nutritional benefits remain the same.

The “Cold Processed” question often comes from the idea that heat denatures protein molecules, potentially impacting their nutritional value. While extreme heat can lead to amino acid loss, the dairy industry does not use these high-heat processes today, and they are not applied to our ingredients.

This is a question we get asked frequently, and the answer is: it depends.

Protein denaturation refers to a change in the structure of a protein from its original, native state to a new form. Think of it like a ball of string unraveling. Denaturation can be caused by various factors, including heat, acid, or agitation.

Milk protein consists of two main types:

Casein: Naturally heat-stable but denatures (gels) when exposed to acid (such as when making yogurt or adding lemon juice to milk).

Whey protein: More sensitive to heat, which is the primary cause of whey protein denaturation. You may have noticed this when heating milk—the thin skin that forms on top is denatured whey protein.

How Does This Affect Our Protein?

Our supplier produces a range of whey proteins for different applications. Some are minimally processed and retain their native structure (“undenatured proteins”), while others undergo higher levels of denaturation depending on their intended use.

For protein shakes: The processing is as gentle and cool as possible to maintain solubility, ensuring a smooth texture when mixed with liquid.

For nutrition bars: Higher heat processing is used to create better texture and flavor, ensuring bars remain soft and enjoyable to eat over time.

Does Denaturation Affect Nutrition?

Not necessarily. While denaturation changes the structure of a protein, it does not destroy its nutritional value. Your body can still digest and utilize the amino acids and nutrients just as effectively.

In fact, many common proteins we consume are denatured—think about cooking an egg or grilling a steak. While their structure changes with heat, they remain highly nutritious and, in some cases, become easier to digest.

Controlled denaturation can actually be beneficial, as it improves texture, solubility, and digestibility depending on the application. For example:

In protein bars: Highly denatured whey retains a soft, stable texture, preventing bars from becoming hard and chewy over time.

In shakes and powders: More native proteins ensure better solubility, leading to a smoother mixing experience.

The Bottom Line

All protein undergoes some level of denaturation during processing, but this does not reduce its nutritional value or effectiveness. The key is using the right processing method for each application—which is exactly what we do at TAHA Nutrition.

Protein powder supports muscle growth, recovery, weight management, and overall health by providing a high-quality source of protein. It helps repair muscle tissues, promotes lean muscle mass, and can aid in satiety, making it beneficial for both athletes and those looking to maintain a healthy diet.

Most people tolerate protein powder well. However, if you have lactose intolerance or allergies, you may experience mild digestive issues. TAHA Nutrition’s grass-fed whey is made for easy digestion, but if you have specific concerns, consult with your doctor before adding protein powder to your diet.

TAHA Nutrition protein powder can be a great nutritional supplement for active kids and teenagers, especially those involved in sports or with higher protein needs. However, protein should primarily come from whole foods, and we recommend consulting a pediatrician before adding protein supplements to a child’s diet to ensure it's appropriate for their individual needs.

Protein is essential during pregnancy and breastfeeding, but we recommend consulting a healthcare professional before using any supplements, including TAHA Nutrition protein powder.

TAHA Nutrition protein powder is gluten-free and free from artificial additives. However, if you have dairy allergies or severe lactose intolerance, consult your doctor before consuming whey protein.

Yes! Protein powder can aid in weight management by promoting satiety and reducing cravings. When combined with a balanced diet and exercise, protein helps preserve lean muscle mass while supporting fat loss.

Protein powder itself does not cause weight gain, but consuming too many calories overall (from any food source) can contribute to weight gain. TAHA Nutrition’s low-calorie, high-protein formula supports lean muscle development and helps control hunger. Read more about this topic on the TAHA blog here

Whey protein and whey protein isolate both provide high-quality protein, but they differ in processing and composition. Whey protein concentrate contains more natural fats and carbohydrates, while whey protein isolate undergoes additional filtration to remove most of the fat and lactose, resulting in a higher protein content per serving. Learn more about the differences here.
