Protein Works Diet Meal Replacement Ingredients


Oats are among the major ingredients of diet meal replacement. These are beneficial when you want to lose weight since fiber-rich oats are filling,[1] which helps you eat less.

Protein Blend

The meal replacement shake contains a protein blend containing soy protein isolate, milk protein concentrate, whey protein concentrate, and sunflower lecithin. These key ingredients boost metabolism,[2] which is essential when you are on a weight loss journey.

Skimmed Milk Powder

There is skimmed powder in the meal replacement shake. Skimmed milk in a calorie-controlled diet adds nutritional content[3] such as Vitamin A, Calcium, protein concentrate, and vitamin D.

Tricalcium Phosphate

The comprehensive meal replacement shake contains tricalcium phosphate. This dietary supplement helps prevent calcium deficiency[4] when eating in a calorie deficit.

Potassium Citrate

Potassium citrate is a mineral supplement added to the Protein Works Diet Meal Replacement. This helps to maintain normal potassium levels[5] in the body, which is crucial for different body functions.

Sodium Chloride

The diet meal replacement shake contains sodium chloride,[6] i.e. salt. Besides improving the quality of the shake, sodium chloride is a crucial compound the body needs for maintaining proper blood pressure, among many other functions,[7] although here it is likely just for flavoring.

Magnesium Oxide

Magnesium oxide is an ingredient in the diet meal replacement shake. It helps to lower blood sugar levels[8] in people with type 1 and type 2 diabetes.

Vitamin C

The meal replacement shakes contain vitamin C, which helps to boost immunity.[9]

Health Benefits Of Protein Works Diet Meal Replacement

The Protein Works Diet Meal Replacement has numerous essential ingredients. These ingredients have health benefits that include:

Lowers Risk Of Heart Disease

The meal replacement shake contains essential ingredients such as vitamin C. This essential vitamin helps prevent conditions such as high blood pressure that lead to heart health problems in many people.

Vitamin C supplementation or eating food rich in vitamin C helps lower cardiovascular disease risk. It helps to lower the levels of low-density lipoprotein,[10] i.e., bad cholesterol in the body.

At the same time, vitamin C also lowers the amount of blood triglycerides.

Nine studies were done that included 293,172 participants. An analysis of these studies revealed that taking 700 milligrams of vitamin C daily lowers the risk of heart disease[11] by 25%. A 2020 update[12] supported this 19-year-old study’s conclusions but also stated more study is needed. 

Promotes Weight Loss

This diet meal replacement contains oats as part of the main ingredients. Oats[13] are good when you want to lose weight, and the fiber involved lengthens satiety: Eating less helps with weight loss since there’s less body fat storage.

Drinking the shake keeps you feeling full longer, which aids in weight loss. Another advantage of oats is that they have few calories, which is important when you want to lose weight.

Your stomach takes time to empty because of the beta-glucan in oats. Beta-glucan[14] produces Peptide YY — a satiety hormone that helps you consume fewer calories.

Lowers Blood Sugar Levels

The meal replacement diet is rich in magnesium oxide, which helps lower blood sugar levels.

People with diabetes can benefit from this shake that contains magnesium. There’s evidence that magnesium helps lower blood sugar levels in people with type 1 diabetes, type 2 diabetes, and even gestational diabetes.

Prevents Vitamin A Deficiency

There are 260 micrograms of vitamins in one 70-gram serving of the meal replacement shake. Therefore, taking the protein shake is suitable for your health since it helps prevent Vitamin A deficiency.

Vitamin A deficiency[15] can lead to poor eyesight or blindness. The vitamin helps convert light to your eye into an electrical signal sent to your brain. Vitamin A makes up the eye’s rhodopsin in the eye’s retina associated with light sensitivity. Having less rhodopsin can cause vision loss at night, especially with age.

Reduces Oxidative Stress Markers

The meal replacement contains vitamin E acetate, important for your body. This vitamin comes in handy in reducing oxidative stress markers. It acts as a powerful antioxidant that boosts antioxidant defenses in the body.

A 2018 study[16] involved 54 participants. They were suffering from diabetic nephropathy, which is kidney damage because of high blood sugar levels. The participants took 800 International Units of vitamin E each day for three months. The results showed an increase in glutathione peroxidase — antioxidant enzymes that prevent oxidative damage to cells.

Boosts Bone Health

A meal replacement shake contains 257 milligrams of calcium. The body needs this essential mineral for bone health and development.[17]

Folks who lack calcium are susceptible to poor bone health, which leads to conditions such as osteoporosis.[18] This condition leads to porous bones that easily fracture.

Boosts Immune System

The body needs vitamin D[19] to boost immune function. This is possible because vitamin D promotes immune response thanks to immunoregulatory and anti-inflammatory properties. Both work to boost immune defenses. 

Potential Side Effects

Meal replacement shakes from Protein Works are beneficial. They contain innovative protein blends with vitamin and mineral blends. However, it’s important also to know the potential side effects of meal replacement shakes.

Food additives in meal replacement shakes can pose health risks, especially in long-term consumption. The good news is the Protein Works meal replacements don’t contain additives or preservatives.

However, it’s important not to take them for an extended period. Ensure your resume consuming solid meals regularly after completing your diet. Meal replacements work when you want to lose weight, but avoid taking the shakes for a long time. 

How To Take Protein Works Diet Meal Replacement

Are you trying to figure out how to take protein works diet meal replacement? Well, you can take the diet meal replacement any time of the day. And the best part is it works well with a calorie deficit plan.

Add one and a half scoops of the Protein Works Diet Meal Replacement in water. You can make the mix sweeter by adding a splash of Zero Syrups. The syrup adds no calories and is sugar-free. Another option is adding a ripe banana for a more filling effect. Shake the mixture well for 10 seconds before you consume it.

Protein Works Diet Meal Replacement Review UK: What Do Real Users Say?

My first ever protein powder and now I don’t want to try any others! It wasn’t chalky or lumpy, and it was sweet but not overpowering or rank in flavor. Also, nice stirred into fat free natural/Greek yogurt for a dessert. This is so far the most cost-effective protein powder I have found, too.


Recently changed to the protein works from another competitor as the shakes were far too sweet. I absolutely love the shakes from protein works. I love the strawberry and cream, chocolate silk and caramel latte.


I really wasn’t convinced that I’d like this having tried a few other meal replacements. I’m normally still hungry, get bored of them and they taste really powdery. SO pleasantly surprised by this. Chocolate Silk is very smooth. I add a banana in for breakfast and make with water and a dash of almond milk , it’s YUMMY! I’m actually looking forward to drinking them. And no hunger… I only want to lose up to 1 stone so hopefully I will be posting weight loss success quite soon, because this is going to be a regimen I can stick to for a change. Absolute win to protein works!

Abi Wilkinson

Lovely shake, wish it just wasn’t as thick.
