Athletes have several alternatives to whey protein, including plant-based options such as pea, rice, hemp and soy protein, as well as animal-based alternatives such as casein and egg protein. These alternatives offer similar benefits for muscle building and recovery, but differ in amino acid profiles and absorption rates. Your choice will depend on your specific goals, dietary preferences and any allergies or intolerances.
Comparison overview: whey alternatives at a glance
Not every whey alternative suits every athlete. Differences in protein content, absorption rate and amino acid profile largely determine when and for whom a particular protein is most suitable. The overview below gives you a quick insight into the main characteristics of each alternative, so you can read further in the sections relevant to you.

In the sections below, you will find a detailed discussion of the pros and cons of each protein type, the best time to use it and its suitability for your personal situation.
Why do athletes look for alternatives to whey protein?
Athletes seek alternatives to whey protein because of lactose intolerance, milk allergies, vegan lifestyle or simply to add variety to their diet. Much of the world's adult population has difficulty digesting lactose, so whey protein can cause stomach upset. Protein powder without lactose offers a practical solution for this group without compromising on muscle building or recovery.
Vegan athletes avoid all animal products, including whey derived from milk. In addition, some athletes deliberately choose different protein sources to diversify their amino acid intake and potentially avoid food sensitivities.
Another important aspect is the whey prices rise that has taken place in recent years. Due to volatility in the dairy market and increased demand, whey prices have risen significantly, leading athletes to look for more cost-effective alternatives that offer similar results.
Exploring different protein sources can also be beneficial for your muscle building. Each protein has a unique amino acid profile and absorption rate, allowing your body to benefit from varied nutritional inputs throughout the day.
Lactose-free protein powder: the best options for athletes with lactose intolerance
Are you lactose intolerant but still want to get enough protein for muscle building? Then lactose-free protein powders are the solution. Lactose-free protein powder includes all protein powders that do not naturally contain lactose or from which lactose has been completely removed during processing. These include all vegetable proteins, egg protein and hydrolysed beef protein.
It is important to note that whey isolate has a significantly lower lactose concentration than whey concentrate, as it goes through additional filtering steps. For athletes with mild lactose intolerance, whey isolate can sometimes still be tolerated. However, if you have severe symptoms, it is better to opt for a completely lactose-free alternative. For post-workout recovery, pea protein or soy protein are excellent choices because of their rapid absorption. For bedtime use, a lactose-free slow-absorbing alternative to casein is lacking, but a blend of rice and pea protein offers a good intermediate solution.
The best plant-based protein powders as an alternative to whey
Pea protein, rice protein, hemp protein and soy protein are the most effective plant-based alternatives for athletes. Pea protein contains all the essential amino acids and absorbs almost as fast as whey, making it excellent for post-workout recovery. A 30-gram serving of pea protein typically provides about 23 grams of protein, including about 5 grams of BCAAs. For a nutritious protein shake without whey, a blend of pea and rice protein provides a full amino acid profile similar to whey.
Soy protein is the only plant protein considered complete, with an amino acid profile similar to animal protein. A 30-gram serving of soy protein provides about 27 grams of protein on average and is relatively high in leucine, an amino acid important for muscle building. Rice protein typically provides about 23 grams of protein per 30-gram serving and is rich in cysteine and methionine, but contains less lysine. Rice protein is therefore best combined with pea protein for a complete amino acid profile. Vegan protein powder based on this combination is now widely available and well researched.
Hemp protein offers healthy omega fatty acids and fibre in addition to protein, but it has a lower protein concentration than other options: around 12 to 15 grams of protein per 30-gram serving on average. For optimal results, many athletes combine different plant proteins, for example pea and rice protein together for a complete amino acid profile.
When choosing plant-based proteins, pay attention to the protein concentration per serving, the amino acid profile and whether artificial additives have been used. Organic options are often purer but more expensive.
Other alternatives to whey: collagen and beef protein
Besides the well-known plant-based proteins and casein, there are two less common but growing categories of whey alternatives worth mentioning: collagen protein and hydrolysed beef protein. Both are lactose-free and therefore suitable for athletes with milk intolerance or milk allergy.
Collagen protein
Collagen protein is extracted from animal connective tissues, such as skin, bones and tendons. It differs from other proteins in that it is rich in glycine, proline and hydroxyproline, amino acids that play a role in joint, tendon and skin repair. Collagen provides on average about 18 grams of protein per 30-gram serving and absorbs quickly. A major drawback is that collagen does not have a complete amino acid profile: it lacks leucine, the amino acid central to starting muscle protein production. Collagen is therefore less suitable as a sole protein source for muscle building, but can be valuable as a supplement to a complete protein. Compared to whey, collagen offers less muscle growth stimulus, but more support for joint and connective tissue repair.
Hydrolysed beef protein
Hydrolysed beef protein is extracted from beef collagen or muscle meat via a hydrolysis process, which breaks down proteins into smaller peptides for faster absorption. The protein content is high: typically about 27 grams per 30-gram serving. Absorption is fast, similar to whey. Beef protein contains a complete amino acid profile and is suitable for athletes with milk allergies who do not want vegetable protein. Disadvantages include its sometimes pronounced taste and animal origin, making it unsuitable for vegans. Compared to whey, hydrolysed beef protein offers similar muscle stimulation but without the milk-related allergens.
Casein as a whey alternative: benefits, action and timing
Casein protein absorbs slower than whey and gradually releases amino acids to your muscles for 6-8 hours. This makes it ideal for use before bed or during extended periods without food intake, while whey is better suited immediately after training. A 30-gram serving of casein typically provides about 24 grams of protein, including an average of about 5 grams of BCAAs per serving.
For muscle building, both proteins are equally effective in the long term. Casein contains all the essential amino acids and has a high biological value. The difference is mainly in the timing of use and absorption rate.
Whey provides a rapid spike in amino acids in your blood, which is beneficial for starting muscle protein synthesis after training. Casein, on the other hand, prevents muscle breakdown over longer periods due to its slow release property.
Many athletes combine both: whey after training for quick recovery and casein in the evening for overnight muscle building and maintenance. This gives you the best of both worlds in terms of absorption rate and timing.
Egg protein as whey substitute: high biological value without lactose
Egg protein has the highest biological value of all protein sources and contains all essential amino acids in optimal proportions. It absorbs slower than whey but faster than casein, making it an excellent middle ground for various purposes. A 30-gram serving of egg protein typically provides about 24 grams of protein and contains about 5.5 to 6 grams of BCAAs on average, one of the highest values among whey alternatives.
For athletes with milk allergies but no egg allergy, egg protein as a whey substitute is a perfect solution. It contains no lactose or milk protein, but still provides the complete amino acid composition you need for muscle building and recovery. Egg protein scores a maximum PDCAAS score of 1.0 (Protein Digestibility Corrected Amino Acid Score), indicating that the protein is fully digestible and provides all the essential amino acids in the right proportions.
Egg protein has an absorption rate of about 3-4 hours, making it suitable for both post-workout use and snacks.
A drawback can be the taste, which some people find less appealing than whey. Egg protein is also often more expensive than plant-based alternatives, but priced similarly to high-quality whey products.
Whey alternatives through food: high-protein products without powder
You don't always need a protein powder to meet your daily protein goals. Many whole foods provide an excellent base and can partially or fully replace protein powders, depending on your intake and training load. Protein powders are primarily a practical tool for those who cannot meet their daily needs through food alone.
- Greek yoghurt: around 10 g protein per 100 g - quickly available - practical as a post-workout snack or breakfast
- Quark: approximately 12 g protein per 100 g - slow absorption due to high casein content - ideal for bedtime consumption
- Eggs: around 6 g protein per egg - high biological value - versatile around training
- Legumes (lentils, chickpeas): about 9 g protein per 100 g cooked - vegetable - good to combine with cereals for a complete amino acid profile
- Edamame and tofu: plant-based - complete amino acid profile - suitable as a daily protein source for vegans
Protein powders are convenient because of their high protein concentration and ease of use, but are not a necessity if your diet already provides enough protein. A consciously composed diet can already cover a large part of daily protein needs without supplements.
Which whey alternative suits your goals, diet and budget?
Your choice will depend on your specific goals, food preferences, budget and any allergies you may have. For quick post-workout recovery, choose pea protein or soy protein. For overnight muscle building, casein is the best option, while egg protein is versatile during the day. For vegans, whey-free protein options such as pea, rice or soy protein are the preferred choice. People with milk allergies can choose from egg protein, hydrolysed beef protein or plant-based alternatives. In case of lactose intolerance, all non-milk-based options are suitable.
When reading labels, pay attention to the protein concentration per serving, the amino acid profile and the presence of artificial additives. Quality products clearly state the origin of the protein and have minimal by-products. Given the ongoing whey prices rise plant-based alternatives can also be more financially attractive. Always compare the cost per gram of protein to find the best value.
When do you use which whey alternative? A practical daily schedule
The timing of your protein intake is at least as important as the choice of protein source. Below is a practical overview by time of day:
- Morning: choose a rapidly digestible protein such as pea protein or soy protein to break the nightly fast - recommended portion: around 30-35 g of protein
- Post-workout: choose fast-absorbing protein such as pea protein, soy protein or egg protein for optimal muscle recovery - recommended portion: about 30-40 g of protein
- In between during the day: opt for egg protein or a vegetable blend for gradual amino acid release - recommended portion: about 25-30 g of protein
- Before bed: choose casein for overnight muscle building and inhibiting muscle breakdown for 6-8 hours - recommended serving: about 30-40 g of protein
Suppose you weigh 75 kg and train four times a week. Then you need around 135g of protein daily (1.8g × 75kg). Divide this over four moments of an average of 34 grams per meal or shake. If you weigh 85 kg, you come to about 153 grams per day (1.8 g × 85 kg), divided over the same four moments of 38 grams on average. Here, the specific protein source matters less than the total daily intake, provided the alternative has a similar protein content per serving.

Frequently asked questions
Can I use different protein sources interchangeably in one day?
Yes, combining different protein sources is even recommended. For example, you can use whey or pea protein after your workout for quick absorption, and casein or egg protein in the evening for prolonged amino acid release. This gives your body a varied amino acid intake throughout the day.
How many grams of protein do I need per day if I switch from whey to an alternative?
Your daily protein requirement remains the same regardless of the source: 1.6-2.2 grams per kilogram of body weight for athletes. Do you weigh 70 kg and train four times a week? Then you need around 112 to 154 grams of protein daily. Divide this over three to four meals of 30 to 40 grams each for optimal absorption. If you weigh 85 kg, then you come to about 136 to 187 grams per day. Most importantly, your alternative should have a similar protein concentration to whey; always check the label to see how many grams of protein there are per serving. The protein source ultimately matters less than your total daily intake, provided the alternative has a similar protein content per serving.
Are plant proteins less effective for muscle building than animal proteins?
No, research shows that plant-based proteins like pea and soy protein are as effective for muscle building as whey, provided you consume enough protein. The secret lies in combining different plant sources to get all the essential amino acids.
What should I do if my new protein doesn't taste as good as whey?
Experiment with different brands and flavours, add it to smoothies with fruit, or mix it with oatmeal or yoghurt. Making a protein shake yourself is easy: blend your protein powder with a ripe banana, some berries and plant-based milk for a nutritious whey-free shake that also tastes good. Many plant proteins have a nutty flavour that combines well with banana, berries or cocoa powder. You often get used to the taste after a few weeks.
How long does it take to see results with a whey alternative?
You should see similar results as with whey within 2-4 weeks, provided you consume the same amount of protein and stick to your training schedule. Muscle building depends more on your overall protein intake and training than on the specific protein source.
Can I use plant proteins if I still eat other animal products?
Absolutely! You don't have to be completely vegan to use plant-based proteins. Many athletes consciously choose plant-based protein powders because of the benefits such as better digestibility, lower cost, or simply to add variety to their diet.
What side effects can I expect when switching to a whey alternative?
Most people actually experience fewer side effects, especially if you are lactose intolerant. In the beginning, your digestion may have to adjust to vegetable proteins, which may temporarily cause some more flatulence. This usually disappears within 1-2 weeks as your body gets used to the new protein source.
