Shipping & Delivery
Is Clean Lean Protein ok for coeliacs & vegans?

Yes. Clean Lean Protein is certified gluten free so it is safe for coeliacs and 100% vegan.

What is the ph level of Clean Lean Protein?

If you follow or are considering following an alkaline diet, then Nuzest Clean Lean Protein is an ideal choice to add to your daily food intake. Nuzest Clean Lean Protein, made from golden pea protein isolate, is the world’s ONLY alkaline protein with a pH reading of 7.8!

Where do you source your peas for the pea isolate and where is the powder is manufactured

We have deliberately chosen pea protein and to source that protein from Europe. The soil, air and water quality of Northern France are generally regarded to be very safe for growing and the process used for isolation is completely free of chemicals. Consumers can feel confident they are selecting a safe vegan protein, rather than fear they are ingesting a protein powder tainted with contaminants.

How much caffeine is in the Real Coffee Clean Lean Protein?

About 20mg per 25g serving.

Are there any sweeteners in any of your protein powders?

Clean Lean Protein is naturally sweetened with a fruit protein derived from a West African plant called the Katemfe Fruit (African Serendipity Berry). The protein is known as Thaumatin. Thaumatin is a protein, but it is classified as a natural sweetener. It is digested in your body just like any other protein.

Is Clean Lean Protein ok for people with Crohn’s disease or Ulcerative Colitis?

Due to the absence of FODMAPs, anti-nutrients, allergens, and gastric irritants, Clean Lean Protein is the perfect protein for people with Crohn's Disease.

How much protein should I be taking after a workout?

This depends on the length of your workout, what your workout consisted of, and your physical size, along with your dietary structure and goals. As a rough rule of thumb, around 1/2 gram of protein per kilogram of body weight consumed within 30 minutes will help encourage recovery and repair of muscle tissue.

Is Clean Lean Protein Kosher?

The Pea Protein Isolate used in Clean Lean Protein is Kosher certified and the manufacturer, which blends Clean Lean Protein, complies with Kosher practices. The finished product however does not have an official Kosher certification.

Is Clean Lean Protein certified organic?

Our peas are grown in France and under strict conditions, and covered to reduce the risk of environmental damage and contamination. Unfortunately, due to local regulations, this means they cannot be certified organic. You can rest assured though that the product is pesticide, herbicide and GMO free. The only certified organic pea proteins available at this time are of uncertain quality and so for the time being we consider Clean Lean Protein to be 'better than organic'.

Why is it important that the product is 'alkaline'?

Our body requires finely controlled pH levels in the blood (as well as tissues and other fluids) in order to maintain optimal health. Modern diets and non-vegan protein sources may cause an increase in acidity in the blood, which then needs to be buffered by the body breaking down bone and muscle tissue to free up 'basic' (alkaline) compounds. Clean Lean Protein provides a high level of good quality protein, without contributing to acid overload in the body.

Can I consume products after the Best Before Date?

Best Before means that it is probably safe to consume past the best before date, but that its nutritional value is likely to be degraded depending on how it has been stored over that time. For example, if it has been kept cool or in a refrigerator it is likely to last longer. In some regulatory environments, the advice is generally 3 months after Best Before Date. However, even though products are likely to be perfectly safe for several weeks past their Best Before Date, in the interest of safety first, Nuzest does not recommend consuming products past their Best Before or Expiry Date.

Why is there froth when I shake Clean Lean Protein in water?

When our Clean Lean Protein is stirred or shaken vigorously, the peptide bonds loosen, and the chain partially unwinds. As the protein unwinds, hydrophobic (cannot be mixed with water) and hydrophilic (can mix and dissolve in water) ends become exposed. The hydrophobic ends reach for the air, whereas the hydrophilic ends stay in the water, and then the proteins coagulate in a structure that’s holds on to air bubbles, resulting in froth. We suggest you making it prior to drinking it, or blending it with some fruit and plant based milk.

Is there a possibility for increased GI inflammation in pea protein?

As far as I know, there is no link between dietary glutamic acid and intestinal inflammation. The role of glutamic acid/glutamate in inflammation is likely to be bidirectional, in other words, high glutamate levels result from inflammation and may drive inflammation, but that is more of a systemic function rather than being a 'contact' issue. The bigger concern is the distortion of the GABA-glutamate ratio, and that, in turn is more likely to result from increased inflammation, metabolic disorder, and fuel inefficiency than by ingesting glutamic acid. In fact, glutamic acid is an important precursor to amino acids (like glutamine). Additionally, we need to look at functional outcomes. In other words, if there is a suggestion that something can drive inflammation or GI problems (plausibility) we then need to look at whether either data or clinical experience shows this (demonstrability). To my knowledge there is no research showing increased inflammation from pea protein use and pea protein isolate is popular for people with IBS, IBDs etc, because of its tolerability. I have Crohn's Disease and use pea protein (around 80g per day) and my inflammatory markers have not been affected at all. :) -Cliff Harvey PhD

Does Good Green Vitality contain caffeine?

The green tea and cocoa bean are included due to their amazing antioxidant potential. They are high antioxidant containing extracts. This means the relative antioxidant level is higher whilst caffeine content will be diminished in the extraction process. The maximum amount of caffeine that could be expected from this amount of combined green tea and cocoa without extraction would be under approximately 7mg per serve (or about 1/25th of a small brewed coffee!), but in reality the amount would be negligible. Good Green Vitality should be completely fine for a caffeine sensitive individual.

Is Good Green Vitality safe for diabetics?

Good Green Vitality is completely safe for diabetics. There are less than 3 grams of carbohydrates per serve so the effect on blood glucose is minimal; and, at around 40 calories per serve, any effect on insulin in type 2 diabetics (and those with metabolic syndrome and pre-diabetic disorders) is almost nil. Good Green Vitality may even help those with diabetes due to the inclusion of ingredients such as chromium and green tea extracts that aid glycaemic control and improve insulin sensitivity.

How is Good Green Vitality labelled 'gluten free' when it contains barley and wheat grass?

The barley and wheat grass in Good Green Vitality are the growing portion of the plant, not the grain. The grain is the part that contains gluten. Every batch of Good Green Vitality is tested for gluten and is certified gluten-free.

I have several health conditions and am taking a lot of medications. Is it OK for me to take Good Green Vitality?

There can often be drug-herb and drug-food interactions with poly drug use. We always recommend that anyone with a pre-existing condition, and those taking medication, consult with a suitably qualified health practitioner before using any nutritional supplement.

Is Good Green Vitality safe for children?

According to Australian and New Zealand regulations, Good Green Vitality is suitable for children aged 4 and over. However the dosage for children aged 4 - 14yrs is half that of an adult (1/2 scoop). Regulations may vary from country to country but, in any event, we do not recommend Good Green Vitality for anyone under the age of 4. Kids Good Stuff is a better alternative for children as the formula was developed specifically for early childhood development.

Is Good Green Vitality suitable for coeliacs and vegans?

Yes, Good Green Vitality is suitable for both coeliacs, vegetarians and vegans. None of the ingredients in Good Green Vitality are derived from animal products and it is certified gluten free.

How is Good Green Vitality labelled as being 'Paleo friendly' when it contains pea isolate?

Good Green Vitality is Paleo friendly. The challenge with legumes on a Paleo or Primal style diet is the 'anti-nutrients' that legumes contain. Our natural enzymatic isolation process effectively removes the phytates, lectins, saponins and trypsin inhibitors, leaving a highly digestible protein that is free of the problems associated with legumes.

Is Good Green Vitality safe to take during pregnancy?

There is nothing in Good Green Vitality that is contraindicated during pregnancy. We have designed Good Green Vitality to be a safe, every day formula for all adult populations. Note: Rosemary is contraindicated for pregnancy in high (therapeutic/herbal medical) doses but the miniscule amount in Good Green Vitality is completely safe. However, we always advise women who are pregnant or breastfeeding to seek independent advice from their health practitioner first.

How is Good Green Vitality different from other greens products?

Firstly it's not just a 'greens' product. Many 'greens' products are simply powdered foods without any fortification of essential vitamins and minerals, or probiotics, bioflavonoids etc. Powdered food blends are OK for a little 'boost' in your smoothie but without taking significantly more than the recommended teaspoon or two, they really do not offer significant supplementation. Of those 'greens' products that do strengthen their powdered foods with added vitamins, minerals, probiotics etc., you will find that Good Green Vitality has significantly higher levels of nutrients than most, if not all, products available in this category. Most importantly however are the forms of those ingredients. Good Green Vitality uses the most bioavailable, 'body-friendly', and effective forms available; many of which are not used by ANY of our competitors. It makes for a more effective, more efficient, and in some areas safer, formula to your health and wellbeing.

Why do I need Good Green Vitality (or any supplement)?

For nutritional insurance - to help plug the gaps in your diet due to poor food quality, soil depletion and imperfect dietary choices; and because of the demands our bodies make for extra nutrients due to environmental toxins and our high-stress modern lifestyles. Nothing should replace a balanced diet of real food - supplements simply help fill the gaps.

Does Kids Good Stuff contain gluten/dairy/soy/peanuts/eggs/GMOs

No - Kids Good Stuff is free from all common allergens, making it suitable for most children aged 4 to 10.

Does Kids Good Stuff contain sugar or artificial sweeteners?

Kids Good Stuff contains no added sugar and is extremely low in naturally occurring sugars. One serve of Kids Good Stuff has less than 1g of sugar. The product is sweetened using Thaumatin (an extract of Katemfe fruit from West Africa) and the natural sweetener Stevia.

Does Kids Good Stuff replace a multi-vitamin?

Yes - Kids Good Stuff is designed to provide complete nutritional support for growing bodies and minds. Kids Good Stuff is more than just a multivitamin - it also contains minerals, pre and probiotics, digestive enzymes, veggies, berries and greens.

What age group is Kids Good Stuff suitable for?

Kids Good Stuff has been developed to help meet the nutritional requirements of children aged between 4 and 10. While it can be taken by anyone over the age of 4, we recommend that children over 10 move on to our adult formula, Good Green Stuff.

Why do some ingredients on the label not meet the RDI?

Legislation requires us to show RDIs for adults on the label, not kids so it can be a little misleading. E.g. the levels of zinc listed are 50% of the RDI for adults but 100% of RDI for children. We do not include 100% of the RDI for all nutrients because at Nuzest we firmly believe that food comes first. Kids Good Stuff is not designed to be a replacement for food; it is a supportive formulation to fill dietary gaps. Think of Kids Good Stuff as topping up nutrient levels rather than being the only source of nutrients.

How is Kids Good Stuff different from Good Green Stuff?

Kids Good Stuff is designed specifically for growing kids, and they have different nutritional requirements to adults. Children have lower requirements for many nutrients (due to lower bodyweight) and so the amounts of green superfoods and nutrients are adjusted to be appropriate for this age group. Likewise, many of the herbs and adaptogens that offer digestive or stress support for adults are unnecessary or inappropriate for kids. We have added protein to support growth and development and bolster the nutritional content of meals and snacks.

How do I take Kids Good Stuff?

Simply stir, blend or shake one serve (two scoops) in water, milk or a dairy free alternative. Best in the morning with breakfast or alternatively as an after school treat with their snack. You can also add Kids Good Stuff to snacks and treats for a nutrient boost. See our recipes section for ideas.

Why is Kids Good Stuff so 'Good'?

Because it's an all-in-one nutritional formula, you can relax and have peace of mind around your child's nutrition. It provides complete nutritional support, is easy to take and tastes great.

Is Kids Good Stuff organic?

Our commitment is to source the best form of every ingredient. This means that while we use lots of organic ingredients (such as spirulina, barley leaf and wheatgrass) we can't always find high quality organic sources for all of the 62 ingredients in Kids Good Stuff. Our decisions are based on selecting the ingredient that provides the best health effect rather than the one that looks best on the label or that delivers the largest profit margin.

My child is prone to hyperactivity, will Kids Good Stuff aggravate this?

Kids Good Stuff provides base line nutritional support for children. It contains ingredients like protein and vitamins that promote naturally sustained energy levels, but does not contain added sugar or artificial sweeteners so should not negatively affect hyperactivity levels.
