How can I gain muscle as a Vegan? Click to expand

Gaining muscle as a vegan isn't much different from gaining muscle as a non-vegan. In order to gain muscle you have to supply your body with enough calories and protein throughout your day. You actually need to eat more calories than your body needs, which will allow it to store the excess energy as weight (part of which will be muscle mass). If you have a high metabolism, your body is using more calories throughout the day than usual, so it requires that you eat even more to get into your calorie surplus. Also, if you are exercising frequently, your body uses even more calories.

Consuming enough protein is particularly important to sustain muscle gain. Pairing a protein supplement like Gainful with a regular program of weight training and exercise 3-4x per week is a great way to promote a healthy, gradual increase in muscle mass.

And, of course, the rest of your diet is extremely important! We're happy to give you a high calorie formula, but we still recommend getting most of your nutrition from your food (supplemented by protein powder). Remember that if you aren’t in the caloric surplus, weight gain will not occur.

Do your best to include fruits and vegetables, grains, lean protein foods, and dairy products. If you are finding it difficult to gain weight, you can include some more calorie-dense foods, nuts and seeds, peanut butter, avocados, plant oils etc. Try to eat very frequently throughout the day to help get all of the nutrition you need. Snack in between meals and before bed when you can. It’s tough to get all of your calories you need if you are just eating a couple meals a day – especially if you have a fast metabolism.

A great way to include your protein powder into your muscle building routine is to make smoothies with it. If you blend your personalized protein powder with nut butters, honey, and fruit you can make a really delicious smoothie while greatly increasing the calories, protein, and other nutrients added by the whole foods. A 1,000+ calorie smoothies sounds like a tall order, but is actually very easy to whip up. However, you shouldn't go overboard when packing on calories, as it can cause rapid and unhealthy weight gain (which in turn leads to adding unnecessary fat). Just a few hundred extra calories per day should lead to a gradual healthy weight gain of a couple pounds per month. Weight and muscle gain are very slow processes when done correctly.

If you'd like to get serious about a specific nutrition plan, reach out to your Registered Dietitian by logging into Gainful.com and navigating to the "My Dietitian" tab.

Are there amino acids in my protein powder? Click to expand

Absolutely! To view the exact amino acid profile for your personalized blend, take the quiz and click on the "Amino Acid Profile" dropdown in the "My Blend" section

Do you offer BCAAs? Click to expand

While we don't currently offer BCAA supplements, our protein powders can supply a significant amount of naturally-occurring BCAA's. Most of the time, the BCAA's that occur naturally in a scoop of protein powder will be greater than a BCAA supplement can offer. All of Gainful's personalized protein powder blends are complete in amino acids and have a lot more nutrition than simple BCAA's supplements.

How can I gain weight and bulk up? Click to expand

Gaining weight and bulking up are frequent topics of discussion with Gainful customers. There are many factors that contribute to weight gain, and it's not enough to simply have your personalized protein powder and expect a magic formula.

To achieve weight gain, you have to be in a calorie surplus. This means consuming more calories per day than your body would need to maintain a stable weight. Eating an extra few hundred calories per day should result in a slow and healthy weight gain. We suggest shooting for only a couple pounds per month. This may seem slow compared to your overall weight gain goals, but it definitely adds up, and gaining weight is a slow process. Along with that, of course you want to consume enough protein to support the weight gain.

Your personalized protein powder will help supply both calories and protein to your day, but the rest of your diet is super important too! We're happy to give you a high calorie formula, but we still recommend getting most of your nutrition from your food (supplemented by protein powder).

We don't recommend turning to junk foods to put on weight. You should still be eating a lot of fruits and vegetables, grains, dairy alternatives, and protein sources (from food and protein powder both). If you are really struggling to gain weight though still, you can try including some more calorically dense foods like nuts and seeds, peanut butter, red meat, high fat dairy, fatty seafood, whole eggs, etc. Try to eat very frequently throughout the day to help get all of the nutrition you need. Snack in between meals and before bed when you can. It’s tough to get all of your calories you need if you are just eating a couple meals a day – especially if you have a fast metabolism.

A great way to integrate your protein powder into your weight gain routine is to make smoothies with it. If you blend the protein powder with milk, yogurt, peanut butter, ice cream, honey, or fruit you can make a really delicious smoothie while greatly increasing the calories, protein, and other nutrients added by the whole foods. A 1,000+ calorie smoothies sounds like a tall order, but is actually very easy to whip up. However, you shouldn't go overboard when packing on calories, as it can cause rapid and unhealthy weight gain (which in turn leads to adding unnecessary fat). Just a few hundred extra calories per day should lead to a gradual healthy weight gain of a couple pounds per month. Weight and muscle gain are very slow processes when done correctly.

And, of course, you can always try tracking calories. Mobile apps like MyFitnessPal can help you track all of your food and tell you how many calories you are eating. If you are not getting any weight gain, simply bump the calories up by a little bit and continue to monitor. Make small changes until you start to see the results that you want.

Love the product and flavors.

Allergic to many proteins. Being able to customize the blend to what my body can handle has been critical in my weight and strength gain. Love the product and flavors. Great customer service as well.

I’m gaining little bits at a time, so this is definitely working

Tried a few of the “so called best protein powders” and, kept losing more weight. I can not afford to do that, I’m a lot smaller then I should be. But, Gainful is the best I’ve ever had, and will continue to take this powder. I eat healthy, and live an active lifestyle, and now I’m gaining little bits at a time, so this is definitely working well for myself. The coaching is phenomenal, and the price is just right, especially when it’s made for me.

[…] Gainful was such a great addition and has now became a no brainer!

The protein powder doesn't taste chalky, you get to choose flavor sticks (I love the matcha!), has a whole 26g of protein and, most importantly for me, the ingredients are super clean! Eating right is not the easiest in college but Gainful was such a great addition and has now became a no brainer! Also, for the price vs quality, I am so happy with it.
