The Best Protein Powder For Weight Gain
The best way to gain weight is to gain muscle, and protein powders are a fantastic way to do just that.
But, of course, not all protein powders are made equal so you'll want to find one that provides your body the calories and protein it needs to gain weight without the unnecessary fillers and additives.
And to help you out, I put together this list of what I think are the 20 best protein powders for weight gain!
Whether you're looking for top-notch whey protein, egg protein, or plant-based protein options it's on this list.
So let's not waste any more time and jump right in!
1. Naked Mass
If you want to gain weight quickly and effectively, Naked Mass is one of the best protein powders you can reach for. A serving provides an incredible 1250 calories and 50g of protein.
The protein powder only has 4 ingredients - a blend of whey & casein protein, organic cocoa, organic maltodextrin, and natural flavor for the chocolate and vanilla versions.
Although this is one of the pricier options on this list in terms of price per serving, you can easily extend your use by opting for one scoop instead of four. A scoop still provides over 300 calories, the highest on this list.
Get it in unflavored, chocolate, or vanilla here.
2. Vegan Naked Mass
Those on a plant based diet don't have to miss out on the weight gain benefits of Naked Mass, because they also make a vegan version!
