How many grams of protein powder should you take per day

To determine the most suitable dose, you should start with your total daily protein requirement, meaning the amount of protein you should consume from both food and supplements.

For a healthy adult with a sedentary lifestyle, the general nutritional reference is approximately 0.8 g of protein per kg of body weight per day. People who exercise regularly, particularly those who do resistance training, may need more. For many people who train, a general guideline is approximately 1.4–2.0 g/kg per day, adjusted according to the type of activity, training intensity and individual goals.

These values refer to total protein intake, not the amount that must necessarily come from powder. For example, someone who already meets their requirements through meat, fish, eggs, dairy products, legumes and other foods may not need any supplementation.

To calculate how much protein powder to take, follow these steps:

1. Estimate your daily requirements: consider your body weight, physical activity and goals;
2. Assess your dietary protein intake: meals and snacks all contribute to your daily total;
3. Calculate any shortfall: a supplement can be used to make up the difference;
4. Check the label: 30 g of powder does not necessarily provide 30 g of actual protein.

These amounts are general guidelines for healthy adults. If you have kidney or liver disease or another condition requiring specific dietary management, your requirements should be assessed with a healthcare professional.

Recommended doses for muscle growth

People who lift weights and want to build muscle should consider their protein intake alongside their energy intake, training quality and recovery. Protein provides the amino acids needed for muscle protein synthesis, but consuming ever-increasing amounts does not automatically lead to greater muscle growth.

For many adults who do resistance training, a general total intake of approximately 1.6–2.0 g of protein per kg of body weight per day may be suitable to support muscle growth. Individual needs can vary depending on training experience, diet and goals.

A person weighing 70 kg who aims for 1.6 g/kg should consume approximately 112 g of protein per day in total. If they already get 90 g from meals, the shortfall is around 22 g of actual protein, not necessarily 22 g of powder.

Consistent training, sleep and adequate energy intake remain essential factors in supporting muscle development.

Ideal amount for weight loss

During a weight-loss plan, the goal is to reduce body fat while trying to preserve muscle mass. To achieve this, it is important to combine a sustainable calorie deficit with an adequate diet and, whenever possible, regular physical activity and resistance training.

Adequate protein intake can help maintain lean mass during weight loss and promote satiety. However, the ideal amount depends on body weight, activity level, the size of the calorie deficit and individual circumstances.

For a physically active person following a weight-loss plan, a general range of approximately 1.4–2.0 g/kg per day may be considered, but this is not a prescription that applies to everyone. Different calculation methods may be appropriate in some situations, particularly in cases of obesity or specific medical conditions.

Protein powder can be useful if it helps you meet your requirements without making meal planning more complicated. However, it is not a weight-loss product in itself: results depend mainly on the overall energy balance and how sustainable the dietary plan is.

Daily protein requirements for women

Women's protein requirements are calculated using the same principles as men's: body weight, physical activity, health status and goals. There is no fixed dose of protein powder specifically for all women, nor is it automatically necessary to reduce protein intake compared with that of a man with similar characteristics and goals.

For a healthy adult woman with a sedentary lifestyle, the general guideline is approximately 0.8 g of protein per kg of body weight per day. With regular training, especially when the goal is to increase strength or muscle mass, requirements may be higher. For many active people, a general range of approximately 1.4–2.0 g/kg per day may be useful, with individual adjustments.

For example, a 60 kg woman who does resistance training might consider a total intake of 1.6 g/kg, depending on her needs, equal to 96 g of protein per day. This amount includes all food sources and any supplements: it does not mean she should consume 96 g of protein powder.

Protein powder can be a practical solution when meals do not make it easy to reach the desired protein intake. Alternatively, you can increase or better distribute servings of foods such as eggs, fish, dairy products, legumes, tofu and other protein sources.

Frequency and timing of intake

Protein powder can be taken at different times of the day, depending on your routine and how you distribute your meals. There is no universally best time: in most cases, meeting your daily protein requirements is more important than the exact minute you take the supplement.

For many people, it may be convenient to use it after training, at breakfast or as a snack. The choice also depends on when you ate your last meal, how long it will be until the next one and how much protein you have already consumed.

Frequency should therefore be determined by your actual needs. If your diet already meets your requirements, there is no reason to automatically add one or more servings of protein powder every day.

Supplementing immediately after training

The period after training can be a convenient time to consume protein, especially if your next meal is still some time away or you cannot eat straight away. Protein provides amino acids that support the muscle tissue repair and adaptation processes that follow exercise.

However, you do not need to drink a shake the very second your workout ends. The muscle response to training develops over time, and total daily protein intake, together with meal distribution, plays an important role. If you have eaten a protein-rich meal in the preceding hours and plan to eat again soon, a supplement may not be necessary.

A serving of protein powder can be a convenient option after a workout, but the amount should be chosen according to individual requirements and the actual protein content of the product. Whether to take creatine with protein before or after training should also be considered.

Taking protein powder on rest days

On days when you do not train, your body continues its recovery and adaptation processes. For this reason, protein requirements do not disappear on rest days, and maintaining a total intake consistent with your training programme may be helpful.

If your diet is inconvenient or insufficient to meet your requirements, you can also use a serving on a day when you do not train.

The decision therefore depends on your overall diet, not on whether you have a gym session that day. It is helpful to maintain regular eating habits, distribute protein sources across meals and assess your intake over the course of the day.

You do not need to increase your dose on training days and automatically reduce it on rest days. The goal is to meet your individual needs with a sustainable plan that remains appropriate over time.

How to take protein powder

Protein powder can be used in several ways, depending on the formulation and personal preferences. The simplest method is to mix the serving indicated on the label with water or a beverage that suits your dietary needs.

It can also be added to yoghurt, porridge, smoothies or batter for certain recipes. In these cases, it is important to consider all the ingredients used, because the energy and nutritional content of the preparation will vary according to the quantities and foods chosen.

To obtain a smooth mixture, gradually add the liquid to the powder and stir until the lumps disappear. The amount of water or other beverage should follow the product instructions and can be adjusted to achieve a thinner or creamier consistency, provided this is compatible with the recommended method of use.

Breakfast ideas and recipes

Breakfast can be a convenient time to use protein powder, especially when you are short on time or want to make your meal higher in protein. The supplement can be added to simple recipes, taking care to ensure that it is compatible with the ingredients and the instructions on the label.

Here are some ideas you can adapt to your preferences:

• Protein porridge: prepare oats with water or a plant-based drink, then add the powder once the mixture is ready and not excessively hot, stirring to distribute it evenly;
• Pancakes: you can add a small amount of protein powder to the batter along with the other recipe ingredients. The texture may vary depending on the formulation used;
• Smoothie: mix the powder with water or a beverage of your choice and, if you like, add fruit or other ingredients compatible with your dietary plan;
• Yoghurt with cereal: you can mix the powder into yoghurt gradually to avoid lumps, adjusting the consistency with a small amount of liquid.

When adding protein powder to recipes, it is important to consider the overall nutritional result. Fruit, cereals, nuts, yoghurt and other ingredients contribute to the calories, carbohydrates, fats and protein in the meal.

How to take it to improve digestibility

The tolerability of protein powder varies from person to person and may depend on the formulation, the amount consumed at once and the other ingredients in the product. If you experience bloating or gastrointestinal discomfort, it is helpful to check the serving size and the supplement's composition first.

Some practical strategies may help you find a more suitable way to use it:

• Follow the recommended serving size: consuming an excessive amount at once may make digestion less comfortable for some people.
• Prepare the product as directed: use the amount of liquid suggested on the label and mix thoroughly.
• Assess your individual tolerance: if a large serving causes discomfort, you may wish to consult a professional about distributing your protein intake differently.
• Check the ingredients: sweeteners, flavourings and other components may affect individual tolerance.
• Consider the lactose content: people with a diagnosed intolerance can look for products suited to their needs, carefully checking the label.

Whey protein concentrates may contain varying amounts of lactose depending on the production process, while other formulations may contain less. However, a lactose-related claim should not be confused with the absence of milk proteins: people with a milk protein allergy must follow different guidance and should not automatically consider a lactose-free product safe.

People who are sensitive to lactose can consider incorporating lactose-free protein powder into their routine. The choice should still be based on the product's composition and individual needs.

Frequently asked questions

How many scoops equal 30 grams of protein powder?

The number of scoops needed to obtain 30 g of protein depends on the weight held by each scoop and the percentage of protein in the powder. 30 g of powder does not necessarily equal 30 g of protein: part of the weight may come from other ingredients.

For example, if a powder contains 80 g of protein per 100 g of product, a 30 g serving of powder provides approximately 24 g of actual protein. To obtain 30 g of protein from a product of this type, you would need approximately 37.5 g of powder.

Can taking protein powder every day be harmful to your health?

For a healthy adult, taking protein powder daily in appropriate amounts can be compatible with a balanced diet when the supplement is used to meet protein requirements. However, powder is not essential and should not be used to increase total protein intake indiscriminately.

It is important to consider the total amount consumed throughout the day, diet quality and any medical conditions. Anyone with kidney disease or other conditions requiring control of protein intake should agree on the appropriate amount with their healthcare professional.

How much protein powder should a person weighing 70 kg take per day?

For a person weighing 70 kg, the amount of protein powder depends on their total requirements and how much protein they already obtain from food. It is therefore not possible to establish an appropriate dose based on body weight alone.

• A sedentary person using a guideline of 0.8 g/kg would have an indicative requirement of approximately 56 g of protein per day;
• A person who trains regularly may need more: with a target of 1.6 g/kg, the total would be approximately 112 g per day.

These figures include all protein sources. If a person weighing 70 kg already consumes 100 g of protein through meals and their daily target is 112 g, any supplementation would need to cover a shortfall of approximately 12 g of actual protein. The amount of powder required will depend on the product's protein concentration.

Is it better to take protein powder in the morning or before bed?

There is no universally better time between morning and evening. Protein powder can be taken at breakfast, as a snack, after training or at another time that helps you meet your daily requirements.

In the morning, it can be convenient for people who have little time to prepare breakfast or want to supplement a meal that contains little protein. Before bed, it may be an option if daily protein intake is still insufficient or if you want to include a protein source in your evening routine.

Some people choose casein before going to bed because it is digested relatively slowly compared with whey protein. However, this does not mean that taking it before bed is essential or that evening intake automatically guarantees better results. The choice depends on protein requirements, tolerance and meal distribution.

The amount of protein powder to take each day depends on individual requirements and the protein already provided by the diet. People who train may have higher protein needs, but supplements are only intended to make up any shortfall: there is no universal dose that works for everyone.

Protein powder can be used after training, at breakfast or at other times of the day, depending on your needs. When choosing the amount and how to take it, it is important to check the label, consider product tolerance and maintain a varied and balanced diet.
