10 Best Mass Gainers in the Philippines 2026 | Buying Guide Reviewed by Nutritionist-Dietitian

Mass gainers vary significantly in calorie content, so select one that aligns with your weight gain goals and desired pace.

There are fast-digesting proteins, and there are slow-digesting ones. Fast-digesting types quickly rush nutrients to your muscles right after a workout to kickstart recovery, while slower-digesting proteins break down over several hours to supply a steady stream of amino acids. Below are the types of protein you will commonly encounter in mass gainers:

• Whey protein - Provides all nine essential amino acids and absorbs rapidly, making it ideal for post-workout recovery when muscles need quick nourishment.

• Casein protein - A complete protein like whey that digests much slower. It gives a steady release of amino acids that aids muscle maintenance and prevents breakdown during long rest periods like sleep.

• Soy and pea proteins - Act as excellent plant-based alternatives for anyone who is lactose intolerant or on a vegan diet, as they still actively support muscle development.

  
  

If possible, look out for a mass gainer that combines these fast- and slow-digesting proteins so your body gets immediate post-workout fuel along with sustained nutrition for continuous growth.

The protein-to-carb ratio dictates how many grams of carbohydrates you get for every gram of protein in a serving. To support lean muscle gain, look for a 1:3 or 1:4 ratio. For example, if a powder offers 30 grams of protein, the carbohydrate count should be between 90 and 120 grams. If a mass gainer offers 250 grams of carbs for only 20 grams of protein, the ratio is too high and may just cause unwanted fat accumulation.

Pay attention to where these carbohydrates come from. Choose formulas that use complex carb sources like oat flour, sweet potato powder, or brown rice powder for sustained energy. Maltodextrin is also a common and effective carb source because it digests easily and quickly replenishes your energy stores after heavy workouts.

Since mass gainers are consumed regularly, it’s important to choose a formula that suits your dietary needs and digestive tolerance. If you are lactose-intolerant, look for lactose-free options or those made with easier-to-digest protein sources. 

You may also prefer lower-sugar formulas if you want to manage your sugar intake, while products with digestive enzymes like protease, lactase, or amylase may help improve digestion. For those with sensitivities, consider formulas with simpler ingredient lists and fewer unnecessary additives, such as artificial colors or fillers.

You will be drinking this supplement regularly, so finding a mass gainer supplement that actually tastes good is crucial for sticking to your regimen. Instead of settling for a brand that only makes a single flavor, look for product lines with multiple flavor options so you don't experience flavor fatigue. Common flavor options for mass gainers are chocolate, vanilla, strawberry, and cookies and cream.

If you plan to blend your powder with extra ingredients like bananas, peanut butter, or oats to further boost calories, vanilla or unflavored mass gainers are your best bet so the flavors do not clash with each other.

Mass gainers require significantly larger scoop sizes than standard protein powders, meaning you will run out of a standard tub much faster. To get the best value for your money, purchase larger tubs or bags (typically 5 lbs to 12 lbs) once you have found a formula and flavor you trust.

Check if the packaging is resealable, too. A sturdy plastic tub with a tight screw-on lid or a heavy-duty pouch with a strong zipper seal is essential to prevent moisture and pests from getting in, keeping your powder fresh down to the last scoop.
