Ultimate Slow Releaser

NIGHT85 is a milk protein concentrate powder derived from ultra-filtered skimmed milk. It is comprised of both casein protein and whey protein in a ratio of 80:20. NIGHT85 provides a slow digesting protein source that releases amino acids to your muscles over a long period of time.

Leading Manufacturing Processes

Manufactured by ultrafiltration of skim milk NIGHT85 has a range of superior functional and textural properties compared to many other casein proteins.

Low In Fat And Carbs

NIGHT85 has a fat content of only 1.5% and carbs of 3.9% in the form of lactose, making it ideal for use as a meal replacement or before bed shake.

High in Protein

NIGHT85 has an impressive protein content making it a great option for boosting daily intake. In natural form it has an 85%+ protein content making it ideal for supporting lean muscle growth.

Slow Digesting

NIGHT85 is made up of 80% casein protein and 20% whey protein. This makes it extremely slow digesting and will provide amino acids to the body for 6-8 hours.

New Zealand Sourced

Not all protein powders are made equally, NZ proteins are considered the best in the world due to industry leading livestock processes and strict government regulations.

Rich Amino Acid Profile

NIGHT85 contains a complete amino acid profile ideal for rebuilding muscle and providing vital macronutrients to the body.

Muscle Gain & Performance

Ensuring your body receives a regular supply of protein is essential for supporting lean muscle growth. Protein consists of amino acids which are the building blocks of muscle and allow us to build, repair and maintain muscle tissue.

Building muscle mass essentially involves the process of lifting heavier weights, tearing the muscle fibres and then rebuilding them stronger and bigger and this is where regular protein intake comes in. Current research indicates roughly 2.2g of protein per kg of body weight is required for building muscle. For an 80kg male this equates to 176g/day which equates to roughly 30g-40g per meal spread over 5 meals.

Protein can be attained from a wide range of wholefood sources such as fish, chicken, and beef as well as non-animal sources such as quinoa, green peas and nuts. Protein can also be attained in supplement form, most commonly in powders such as whey protein powder, pea protein powder or rice protein powder. These powders allow for a convenient way to add additional protein calories into your daily diet and assist with muscle building needs.

  • Energy Boost
  • Muscle Growth

Weight Loss & Toning

The lowest calorie way to consume protein is in a protein shake. Products such as Whey Protein Isolate have extremely low levels of carbs and fats, meaning the calories you consume are virtually pure protein. If you’re looking to minimise your caloric intake and burn any excess fat, a high protein diet is a must. Not only will a high protein diet ensure your body draws its energy from excess fat stores, it’ll also make sure you don’t feel hungry and crave unplanned cheat meals.

Nevertheless, we wouldn’t advise you rely on protein powder as your only source of protein. Rather it should be used to supplement a well-rounded diet.

What is Night85 slow release blend casein protein?

True Protein Night85 is a milk blend concentrate powder that boasts a 80% protein content for a slow, steady release while you sleep. Combining both casein protein and whey protein in a unique 80:20 ratio, Night85 provides a complete set of amino acids which restore your muscles over a long period of time. Derived from ultra-filtered skimmed milk, Night85 has a fat content of only 1.5% and carbohydrates of 3.9%. Night85 has an impressive protein content that makes it ideal for boosting your daily protein intake and supporting lean muscle growth just before bed.

What is the difference between casein and whey protein?

True Protein Night85 uses a combination of both casein and whey protein in a specific 80:20 ratio designed for overnight protein restoration. Mixing these two proteins together ensures a complete slow release and easy digestion protein intake. Casein carries the same amino acid profile as whey protein, however each has a unique absorption rate. Casein is the slower acting form of protein, once it has been through an ultra-filtration process and created into a protein powder. Because casein works slower, the amino acids maintain and protect protein in the body for a longer period, making it the perfect source of protein to regulate protein levels overnight. When the body works hard throughout the day whether it be through exercise or physical and mental exhaustion, the protein levels in our body deplete. Casein works to slow down the process of protein breakdown and therefore over a long period of time maintains and restores protein stores in the body. Whey quickly increases amino acids upon supplementation and boosts our protein synthesis process to jump start the functions of casein in the body. Casein and whey protein work better together especially when the body is in a state of rest. Night85 uses whey to increase protein synthesis at a high rate and casein through a gradual state of release to repair and build protein stores.

Why should I take Night85 before bed?

True Protein Night85 works to supplement the protein stores lost after a full day's work. Whether you are exercising intensely throughout the day or are looking for a slow absorbing protein to fullfil your daily protein intake, Night85 will work while you sleep to keep a healthy supply of protein and protect the body against further protein breakdown known as an anti-catabolic state. Taking Night85 is ideal as it promotes a sustained supply and release of protein stores while you sleep. Research has proven that casein and whey protein, which are the core ingredients in Night85, support the potential for lean muscle mass and a decrease in overall body fat when complemented with a balanced diet and exercise regime.

Can I take Night85 as a dinner meal replacement?

We recommend using Night85 as an after dinner, before bed protein shake to supplement the protein stores lost after a full day's work. We always recommend a balanced wholefood diet before adding supplements. We do not recommend replacing Night85 for breakfast, lunch or dinner, it should be in addition to your meals. It is best to take the protein shake either 30 minutes to an hour before bed.

How do I take Night85?

True Protein Night85 details directions for use on the back of all packaging. We suggest adding 1 Large TP scoop (30g) to 250-350mL of a liquid of your choice. Night85 is popular for consumption before bed so to reduce the heaviness and discomfort you may experience when trying to fall asleep after consuming any meal before bed, we suggest taking Night85 between 30 minutes to an hour before bed. Because the Night85 formula is a slow release milk protein add extra liquid to lessen the thickness and shake well in a True Protein 600mL shaker bottle.

How is Night85 flavoured?

Here at True Protein we have opted to use organically sourced all-natural stevia to sweeten our flavoured Night85. Stevia is derived naturally from a plant that originated in South America and is 600 times sweeter than sugar. We therefore only need very small quantities of this naturally produced sweetener to flavour large quantities of protein. Our in-house development team has pushed the boundaries of natural flavouring, to develop completely unique flavours that contain no artificial flavours or additives, while possessing a fantastic natural and clean taste.

Does taking Night85 improve sleep?

True Protein Night85 can assist in improving your sleep patterns. True Protein Night85 combines the internal benefits of the complete profile of branched amino acids to ensure you are supplying your body with the correct daily protein dosage. Fulfilling your body with a balanced whole food diet and regular exercise alongside the supplementation of Night85, you will lead a physically & mentally healthier lifestyle and therefore, in effect, your sleep patterns will improve.

Does Night85 have any weight loss benefits?

Our bodies carry out vital tasks whilst we sleep, from producing proteins in the immune system to lowering blood pressure. Getting enough sleep is vital to muscle recovery, as well as mental health and hormone balance. Night85 works to complement a sustainable whole food eating plan and a regular exercise regime. Containing a complete amino acid profile ideal for rebuilding muscle and providing vital nutrition for the body, Night85 works internally while your body rests. Night85 does not solely support weight loss but when working alongside a balanced diet and regular exercise, this supplement promotes the growth hormone which prevents loss of muscle mass and obesity. Night85 is designed with the correct vitamins and minerals for a restful sleep and sustained protein intake essential for leading a healthy lifestyle.

How does casein protein help improve my metabolic rate?

There are many myths and confusing information when it comes to defining your metabolic rate. Everybody, depending on their height, weight, climate you're living in and age, will have different metabolisms. When it comes to the consumption of milk casein proteins, there is evidence to suggest that dairy intake is associated with a decreased presence of metabolic related disorders such as high blood pressure, high cholesterol and high blood sugar. When these levels are stabilised through sufficient dietary supplementation of a whole foods diet and regular exercise, milk casein protein works to support gut health and an improved metabolic rate. It is suggested that through lifting weights, drinking a sufficient amount of water, improving sleeping patterns and managing stress, your body will learn to sustain a healthy body composition. Throughout these changes Night85 can assist in reaching a stabilised metabolism. Night85 is made up of 80% casein protein and 20% whey protein which makes the Night85 formula extremely slow digesting to fuel the body consistently over a 6-8-hour period. Night85 prompts changes in compositions due to controlled protein intake and thus an improved metabolic rate.

Suggested Use

Add 30g (4 heaped tbsp) to 250-350ml of liquid of your choice. Consume 1-3 servings daily or as required. Give preference to consuming before sleep.

True Protein recommends as a guideline 1.5 to 2 grams of protein per kilogram of body weight. This recommendation is based on the assumption that your goals are to build lean muscle and enhance recovery. These guidelines translate to an 80kg person taking roughly 120g to 160g of protein per day. We recommend that you fulfill this quota through a combination of wholefoods and protein supplementation.
