Six major food groups contributed to the total weight of foods and beverages purchased in Australia between 2019 and 2020. Second, behind non-alcoholic beverages (22.6% of the total), milk products make up roughly 18.4% of the estimated 14.5 million tonnes of foods and non-alcoholic beverages sold to Australians. While milk drinkers across Australia and around the world won’t be too surprised, what may shock you is that only 35% of the human population can digest lactose beyond childhood.

According to a 2012 article in the International Dairy Journal, lactase persistence (the ability to digest the milk sugar lactose in adulthood and the opposite of lactose intolerance) is highly associated with a lactase gene mutation that spread across Europe 8000 years ago.


Unfortunately, only a few humans can benefit from lactase persistence, a genetic mutation that enabled early human settlements to outlast intolerant ones. In the same way, milk nurtured children; this liquid gold was a rich source of nutrition that could sustain villages, paving the way for modern agriculture and modern civilisation.


While drinking milk as an adult isn’t lethal to the lactose intolerant, it is certainly unpleasant. Milk can often mean a trip to the bathroom to deal with gastrointestinal issues like cramping and bloating. And as such, many individuals avoid dairy products altogether or opt for dairy alternatives, like A2 milk.


Seeing milk through the lens of innovation, many have jumped on the A2 milk bandwagon thanks to clinically proven benefits like being easier to digest and absorb nutrients. While many brands have decided this is enough, the top scientists, formulators and nutritionists over at NATUREDAY knew they could do better.


Seeking to answer the all-important question, is milk healthy for adults? Their adult milk powder combines the power of A2 milk with an adult milk supplement for a Dairy Plus experience. Ready to take the dairy world on one glass of milk at a time, NATUREDAY A2+ powder milk features a  winning combination of two patented probiotics to improve gut health and optimise nutrient absorption.


Discover for yourself the Benefits of A2+ Milk Powder for Adults.

  1. Patented Dual Probiotics For Gut Health

Time for a quick science lesson from NATUREDAY Dairy. Inside every glass of A2+ milk are 1.7 billion probiotics. Made up of two patented pharmaceutical-grade probiotic strains from the world’s leading supplier, DuPont, NATUREDAY A2+ powder milk promises to improve gut health, deliver healthy digestion and increase your natural immunity. 

Lactobacillus acidophilus NCFM

Lactobacillus acidophilus NCFM is known to improve abdominal pain and bloating in people with irritable bowel syndrome1. It’s also been linked with enhancing immune responses, preventing or treating infection, lowering serum cholesterol, improving lactose metabolism, and increasing the absorption of Calcium and vitamins B12 and folate2.

Bifidobacterium lactis HN019

Bifidobacterium lactis HN019 has been used to treat gastrointestinal symptoms3, 4. A gold-standard review in 2017 identified four clinical trials demonstrating that B. lactis HN019 enhanced cellular immune function in healthy elderly adults5. Scientists are currently investigating its role in maintaining intestinal barrier function during infections, potentially resulting in less diarrhoea8.


Adding these two probiotics is the first step in taking NATUREDAY A2+ adult milk powder to the level of Dairy Plus.

  1. Not Just Any Old Cow

The secret to NATUREDAY A2+ adult milk powder is the carefully selected KiwiCross cows. Each A2 cow is 100% genetically verified to produce only A2 beta-casein. Proudly offering a quality product you can trust, only 1 in 8 cows receive the NATUREDAY seal of approval.


Unlike traditional cow’s milk which features both the A1 and A2 Protein (for reference, a third of the Protein in milk is β-casein), KiwiCross cows produce an increased amount of the all-important β-casein Protein we call A2.


When mainstream milk is digested, the A1 β-casein Protein releases β-casomorphin-7,6 which has been linked to the discomfort that some people feel after drinking milk,2 e.g. abdominal pain, bloating, and flatulence. The A2 β-casein Protein, on the other hand, does not produce β-casomorphin-7, making it easier on your stomach.


Coupled with double the Calcium of regular milk, five vitamins and probiotics for ultimate absorption, NATUREDAY A2+ probiotics milk powder is the better option for drinking milk as an adult.

  1. A Better Source of Protein

It’s no secret that milk is a terrific source of Protein. As we mentioned before, this liquid gold was able to prop up villages during harsh winters as an alternative source of nutrition when nothing else was available. Milk also contains vitamins A, D, B12, Riboflavin, and minerals such as Calcium, Phosphorus, Zinc, and Iodine. 


Pretty impressive, right? Wait until you see how much Protein is in a glass of NATUREDAY A2 + Probiotic milk.


8.4g of protein, equivalent to 1.4 eggs, 50g of meat or 420g of spinach.


Damn. Now, what about Calcium?

  1. More Calcium

Probably the most talked-about mineral in milk is Calcium. Unfortunately, many of us are missing our recommended daily intake (RDI) of Calcium, 1000 mg per day. For the older people in our lives, this increases to 1,300 mg per day. And if you think a glass of milk will help, you’ll need more than just one.


For example, the average daily Calcium intake in New Zealand is 807 mg, with those in Asian countries consuming less than 500mg7.


To tackle this, every glass of NATUREDAY A2 + Probiotic milk offers 72% of the Calcium an adult needs each day. NATUREDAY achieves this by using natural Calcium lactate alongside Vitamin D3 and Vitamin A for improved absorption.

  1. Improved Immune Function

The human gut, or microbiome, contains approximately 100 trillion microorganisms8 which together perform a plethora of critical bodily functions like fermenting dietary fibre, producing vitamins and helping to absorb minerals like Calcium and iron by releasing enzymes.9 They’ve even been known to influence immune function, metabolism, appetite, obesity, and even how people think and behave.9 An extensive review of hundreds of trials found that probiotic supplementation provides people with a wide range of health benefits.8


NATUREDAY Dairy has designed its patented blend of probiotics to compliment the power of the A2 β-casein Protein. In addition to the 1.7 billion Dairy Plus probiotics, NATUREDAY A2+ milk powder contains:


  • More CLA for improving immunity and bone health.
  • More Vitamin E and C to eliminate free radicals and enhance immunity.
  • Added Magnesium to maintain normal nerve and muscle function and support the immune system while also improving blood glucose levels, energy and Protein.


Discover the overwhelming benefits that NATUREDAY A2+ Probiotics Formulated Full Cream Milk Powder can bring to your life. Authentic, delicious and cutting-edge. It’s Absorption PLUS.
