01Whey Protein ConcentrateOur USA-sourced , traceable whey protein concentrate is a natural, high-quality protein packed with essential amino acids for muscle recovery and growth. With a balance of naturally-occurring protein, fat, and carbs, it has a creamy taste and texture while still being high in protein. Ideal for daily use, it supports overall wellness and performance. It contains slightly more lactose than whey isolate but is still considered very low in lactose.
Clinical Study 1 Clinical Study 2
02Whey Protein IsolateOur USA-sourced, traceable whey protein isolate is a highly purified form of whey with high protein content, minimal fats, carbs, and lactose. Fast-absorbing and rich in essential amino acids, it supports muscle recovery and lean growth without excess calories. Its clean taste and versatility make it a top choice for a high-quality protein powder.
Clincal Study 1 Clinical Study 2
03Sunflower LecithinWhey protein is typically sprayed with sunflower lecithin to improve mixability, preventing clumping and making it easier to dissolve in liquids. Sunflower lecithin is a natural emulsifier derived from sunflower seeds, but it's not the same as refined seed oils used in cooking. It contains phospholipids that support cell health and digestion.
04Digestive EnzymesThis vegan digestive enzyme blend helps break down protein, carbs, fats, and fiber for better digestion and nutrient absorption. It includes protease, amylase, cellulase, lactase, and lipase, supporting the digestion of dairy, grains, legumes, and more. By easing digestion, it can help reduce bloating or discomfort, especially for those with sensitive stomachs, ensuring you get the most from your protein intake while supporting overall gut health.
Clinical Study Clinical Study 2
05Green Tea ExtractExtracted from steeped green tea leaves, the health benefits of green tea extract are mostly due to its high antioxidant content. It supports metabolism primarily through its natural compounds called catechins, especially EGCG (epigallocatechin gallate), which can boost fat oxidation and energy expenditure. Adding green tea extract to your routine can support a healthy, active metabolism.
Clinical Study 1 Clinical Study 2
06FiberSmart Soluble Tapioca FiberFiberSmart® is a premium soluble fiber sourced from the cassava root (tapioca). Soluble fiber is great for gut health because it absorbs water and forms a gel-like substance in the digestive tract, which helps feed beneficial gut bacteria and promotes a healthy microbiome. It also slows digestion, leading to more stable blood sugar levels and better nutrient absorption. For satiety, soluble fiber helps you feel full longer, reducing hunger and supporting healthy weight management.

Your questions,
answered.
Are Gainful products 3rd party tested?
Yes - we regularly conduct third party testing on our products. All of our products are manufactured in NSF-certified cGMP facilities, the highest standard for supplement manufacturing. Each raw material is checked for safety and potency. Every Gainful supplement is third party tested for heavy metals and microbial contamination to ensure food safety. Our products also undergo rotational nutrient, contaminant, and adulterant testing to ensure potency, purity, and safety of ingredients, bringing you only high-quality products and peace of mind with every scoop.
Which protein is right for me?
We know performance is personal, so we offer a variety of protein blends to help you meet your specific goals. Not sure where to start? Take our quick 2-minute quiz — we’ll ask about your diet, fitness routine, and health goals to recommend the protein blend that’s right for you.
Is whey protein better than plant-based protein?
Whey protein is a great option if you tolerate dairy — it’s a complete protein with all 9 essential amino acids and is rich in micronutrients like calcium. For those who are lactose intolerant, Gainful offers virtually lactose-free whey options as well! Prefer plant-based? No problem. Our plant proteins combine organic pea and rice protein in a smooth, easily-digested blend to form a complete amino acid profile, so you’ll still get all the benefits of a high-quality protein blend!
How is Gainful protein different?
Our mission is to bring you premium, transparent, limited-ingredient protein. We use clean, effective ingredients in clinically-studied amounts, with nothing artificial, ever. Our products are 3rd-party tested for safety and efficacy. We know performance is personal, and that's why we offer a variety of products and customization that gets you what you need for your body and your goals. Plus - all Gainful proteins come unflavored, and we are the only brand with flavor packets that help you unlock a new protein flavor every day!
What time of day should I take protein?
What matters most is hitting your daily protein goals, not the exact timing. Spreading your intake across meals can help with fullness and muscle maintenance. If you're focused on building muscle or recovery, protein after a workout is ideal. Taking it before bed can also support overnight muscle repair. No matter when you take it, you'll get the benefits!
How our flavor packets work
Step 1 Add 1 scoop of our unflavored protein to 8-12 oz of any ice cold milk or water
Step 2 Add 1 flavor packet to your shake
Step 3 Shake for 30 seconds and enjoy!
