Clear Rice Protein

20g Protein Per Serving

D-Biotin (1% on Maltodextrin)

D-biotin is one of eight forms of the water-soluble vitamin, biotin, also known as vitamin B-7. It is a coenzyme -- or helper enzyme -- for numerous metabolic reactions in the body. D-biotin is involved in lipid and protein metabolism and helps convert food into glucose, which the body uses for energy.

Folic Acid (1% on Maltodextrin)

Folate is the natural form of vitamin B9, water-soluble and naturally found in many foods. It plays a key role in breaking down homocysteine, an amino acid that can exert harmful effects in the body if it is present in high amounts. Folate is also needed to produce healthy red blood cells and is critical during periods of rapid growth, such as during pregnancy and fetal development.

Vitamin B12 (Cyanocobalamin on Maltodextrin)

Vitamin B12 is a nutrient that helps keep your body's blood and nerve cells healthy and helps make DNA, the genetic material in all of your cells. Vitamin B12 also helps prevent megaloblastic anemia, a blood condition that makes people tired and weak.

Vitamin B3 (Nicotinamide)

Vitamin B-3, also known as niacin, is one of eight B vitamins. It plays a role in converting the food we eat into energy. It helps the body to use proteins and fats, and it keeps the skin, hair, and nervous system healthy.

Beetroot Extract

Beetroot boosts your muscles and helps recovery Intense exercise damages muscles.


PerforMelon® watermelon powder contains L-citrulline, an amino acid used in sports performance and cardiovascular health supplements.

L-Arginine HCl

Arginine Hydrochloride is the hydrochloride salt form of arginine, an essential amino acid in juvenile humans. Arginine is a complex amino acid, often found at active sites in proteins and enzymes due to its amine-containing side chain. Arginine may prevent or treat heart and circulatory diseases, combat fatigue, and stimulate the immune system.


L-Tyrosine. L-Tyrosine is an amino acid that is used to produce noradrenaline and dopamine; it appears to reduce stress during exposure to acute stressors (which tend to deplete noradrenaline) and may help to prevent stress-induced memory deficits.

Betaine Base Anhydrous (Tri-Methyl Glycine)

A form of betaine called betaine anhydrous helps in the metabolism of homocysteine, a chemical involved in the normal function of many different parts of the body, including blood, bones, eyes, heart, nerves, and the brain. Betaine anhydrous prevents the buildup of homocysteine seen in people who have problems with its metabolism from birth.


Taurine, or 2-aminoethanesulfonic acid, is a type of amino acid that is found in the body and is considered the most abundant amino acid in the heart, retina, skeletal muscle, brain and immune cells.

Beta Alanine

Beta-alanine is an amino acid that is found mostly in skeletal muscle. It functions a bit differently than other amino acids you may have heard of like leucine or arginine. Leucine and arginine are proteinogenic amino acids, meaning the human body incorporates them into proteins. Beta-alanine on the other hand is a non-proteinogenic amino acid.

Creatine Monohydrate

Creatine Monohydrate is the monohydrate form of creatine similar or identical to endogenous creatine produced in the liver, kidneys, and pancreas. Creatine, in phosphate form, helps supply energy to muscle cells for contraction.


CocoMineral® is an instantised coconut water powdered extract containing the key electrolytes sodium and potassium, which can help to replenish electrolytes lost through sweat during exercise. CocoMineral® is low in fat and high in carbohydrate, meaning it is ideal for replenishing glycogen stores post-workout.

Magnesium Bisglycinate

Magnesium glycinate is a supplement that boosts magnesium levels in people with a deficiency of the mineral. Magnesium is a vital nutrient for regulating many body processes, including muscle and nerve function, blood sugar levels, and blood pressure. This mineral also supports the making of protein, bone, and DNA.

Flavour System

Watermelon, strawberry and hydocurc


Coffeine® is one of the only caffeines which has been naturally sourced and extracted exclusively from coffee beans. Caffeine naturally stimulates the central nervous system and when ingested, blocks the action of adenosine on its receptors which stops the onset of drowsiness. Caffeine extract can help to increase alertness, reduce fatigue and boost energy levels.

Silicon Dioxide

Silicon dioxide is a natural chemical mix of silicon and oxygen that has uses in many food products as an anticaking agent


Maltodextrin is a white powder that is relatively tasteless and dissolves in water. It is an additive in a wide range of foods, as it can improve their texture, flavor, and shelf life

All 3 are amazing! Taste great with ice! Highly recommend

Tastes just like juice!

I've really struggled with bloating from whey-based proteins, so was on the look out for an alternative. This is fully plant-based and super light (it honestly tastes like juice), and doesn't leave me bloated AT ALL! Love it.


Loved being able to try all 3 flavours, FCUS was my fave and perfect just before the gym <3 Have tried most other clear proteins and this one has been the best!
