Choosing protein nutrition can be difficult when every powder seems suited to the same shake. The useful distinction is what you want the powder to do in your routine: provide a particular protein format, fit a daily serving pattern, or deliver a more calorie- and carbohydrate-focused serving. Start there, then use flavor, ingredients, and listed price to break the tie.
Quick take
Do not treat these four powders as interchangeable. The choice is between a plant-oriented formula, two different whey approaches, and a weight-gainer format with a notably different serving profile. Listed prices span USD 28.72 to USD 79.95, so it makes sense to settle on the format first rather than choosing on price alone.

Product notes
OZiva Protein + Herbs for Her
The clearest fit here is a plant-based routine centered on a formulation described with pea protein, brown rice protein, flax seeds, and ashwagandha. Chocolate flavor and a stated one-scoop-daily dosage make it straightforward to place in a regular shake routine. It is also explicitly positioned in its title for women's daily wellness and nutrition. At USD 79.95, OZiva carries the highest listed price of the four. That is its main limitation: shoppers chiefly focused on keeping the listed outlay low have three lower-priced choices. Choose OZiva when the plant-and-herb direction matters more than its price position.
Sports Research Whey Protein Isolate Sports Nutrition Dutch Chocolate
Sports Research puts whey protein isolate at the center, with Dutch Chocolate and 25 servings identified in the title. The description states 25 g of protein per serving alongside 1,000 mg of added L-leucine, giving this option a clearly isolate-focused profile. Its USD 49.95 listed price places it between OZiva and the two Optimum Nutrition powders. One important limitation is in the ingredient declaration: it contains milk and tree nuts, specifically coconut. Pick this one when a whey isolate format is the priority and those listed ingredients suit your preferences.
Optimum Nutrition Gold Standard 100% Whey Vanilla
Optimum Nutrition Gold Standard 100% Whey is the straightforward vanilla choice for someone seeking a 2 lb powder with a whey protein blend. The ingredient list includes whey protein blend, natural and artificial flavor, lecithin, sucralose, and acesulfame potassium. At USD 39.85, it sits below the two more expensive listed options while remaining above Serious Mass. The limitation to weigh is the stated milk and soy content, which is relevant for ingredient-focused shoppers. Choose Gold Standard when a vanilla whey blend is the desired everyday format rather than a plant formulation, isolate-specific option, or mass-gainer serving.
Optimum Nutrition Serious Mass Weight Gainer
Serious Mass has the most distinct role in this comparison: it is explicitly a weight gainer rather than simply a conventional protein powder. The listed 3 lb container is priced at USD 28.72, the lowest price in the group. That makes it the natural starting point for shoppers drawn to its mass-gainer direction. Its limitation is the stated four servings per container, which differs from a powder intended for a longer sequence of smaller servings. Select Serious Mass when that container and serving structure fits your plan, not merely because it occupies the lowest listed price position.
Final recommendation by use case
Choose OZiva Protein + Herbs for Her for a plant-based option with a one-scoop-daily dosage. Choose Sports Research Whey Protein Isolate if the stated 6.9 g of BCAAs per serving is meaningful to your preferred whey format. Pick Optimum Nutrition Gold Standard 100% Whey when vanilla and mixing with water or milk are your priorities. Choose Optimum Nutrition Serious Mass Weight Gainer when a two-scoop serving listed with 1,260 calories, 50 g of protein, and 253 g of carbohydrates matches the role you want the shake to play.
