You may work out as hard you can but the best protein powder could carry you the extra mile to the body you want. With literally thousands of protein powder options lining the shelves and each boasting its benefits, it’s easy to feel overwhelmed.
Here is our guide to the best protein powders that will make a difference when you work out. From whey to plant-based options, we looked at a wide range of protein supplements, considering factors such as protein type, concentration, additional ingredients, and more.
It’s the first step to the body of your dreams.
What protein powder is most effective?
Choosing the right protein powder depends on your fitness goals, dietary preferences, specific health considerations and other factors. Here are the 7 things you should consider when looking for the best protein powder for you.
1. Type of protein
- Whey Protein: Derived from milk, whey protein is a fast-digesting protein that is rich in essential amino acids. It’s an excellent choice for post-workout supplementation.
- Casein Protein: Also derived from milk, casein is a slow-digesting protein. It provides a steady release of amino acids and is often taken before bedtime.
- Pea Protein: Suitable for vegetarians and vegans, pea protein is hypoallergenic and easily digestible. It’s a good source of branched-chain amino acids (BCAAs).
- Soy Protein: Another plant-based option, soy protein is a complete protein, meaning it contains all essential amino acids. It’s suitable for vegetarians and vegans.
2. Protein concentration
Check the protein content per serving. Higher protein concentrations are generally more effective for muscle building and recovery. Look for products with at least 20-25 grams of protein per serving. All the protein powders on this list meet that criteria.
3. Other ingredients
Some protein powders may contain added sugars, artificial sweeteners, preservatives, or fillers. It’s advisable to choose products with minimal additives, especially if you have dietary restrictions or sensitivities.
4. Allergens
Consider any allergies or intolerances you may have. If you are diabetic, lactose intolerant or allergic to dairy, plant-based protein powders are the way to go.
5. Flavour and texture
Protein powders come in various flavours, so choose one that you enjoy. Also, consider the texture and how well it mixes with your preferred liquids, hot or cold.
6. Intended use
Different protein powders may be more suitable for specific purposes. For example, whey protein is often recommended for post-workout recovery, while casein may be a better choice for sustained protein release.
7. Nutritional profile
Look beyond just protein content. Check the overall nutritional profile, including the vitamins and minerals, and the ratio of macronutrients (carbohydrates and fats).
Talk with your healthcare professional or a registered dietitian, especially if you have any specific health concerns or dietary restrictions before you decide. They can provide personalised recommendations based on your individual needs.
How much protein do I need?
The recommended daily protein intake for the average Singaporean adult aged 18-49 is approximately 0.8g/kg body weight. This means that those aged 18-49 should consume approximately 50g to 60g of protein a day.
Older adults aged 50 and above have a higher daily recommended protein intake at 1.2g/kg bodyweight.
If you work out and want to build muscle, you should consume 1.2g-2.0g of protein per kg of bodyweight. Please note that your protein should come from a combination of protein powder and a balanced nutritious diet. Researchers recommend getting a maximum of 25-50g of protein per day from protein powder.
Best protein powder
Even the best protein powder brands can have vastly different approaches to formulating their products. For example, some brands come in huge 2kg jars while others come in 500g packs. However, the latter could be more concentrated, meaning that it contain the same amount or possibly even more protein per serving.
To make it easier for you to choose, I have included the number of servings in each container of protein powder on our list. The 11 protein powders are listed from lowest cost per serving to the highest*.
Use that to determine how much protein you get for every dollar you spend.
