Every Protein Powder deal here is ranked by cost per dose— what you actually pay per serving, not the sticker price — because forms and absorption differ, so the cheapest bottle isn’t always the cheapest dose.
Right now the best value across our full Protein Powder catalog is at $0.70 per serving.
There is no standalone NIH ODS fact sheet for protein; ODS covers it within its health-professional fact sheet "Dietary Supplements for Exercise and Athletic Performance," which lists protein among the most common sports-nutrition ingredients. ODS states that protein "builds, maintains, and repairs muscle" and that, based on numerous clinical trials, it "optimizes muscle training response during exercise and subsequent recovery period." ODS notes that athletes must obtain the nine essential amino acids (EAAs) from the diet or from supplementation to support muscle growth, maintenance, and repair. ODS frames a nutritionally adequate diet as critical and states that supplements might enhance performance only when they add to — not substitute for — that dietary foundation, with athletes able to obtain additional protein from more protein-containing foods and, if needed, protein supplements. ODS does not present protein as a cure, treatment, or preventive for any disease. — per NIH Office of Dietary Supplements; not medical advice.
Per NIH ODS, protein powders and drinks are available, most of which contain whey, one of the complete proteins isolated from milk (complete proteins are those that contain all EAAs). ODS states that digestion of casein, the main complete protein in milk, is slower than that of whey, so the release of amino acids from casein into the blood is slower; it also notes that soy protein lacks the EAA methionine (and may lose some cysteine and lysine in processing) and rice protein lacks the EAA isoleucine, so many protein supplements combine sources and users should select singular or complementary proteins that together provide all EAAs. On branched-chain amino acids, ODS states that protein powders made from complete proteins — "especially whey, which has more leucine than either casein or soy" — automatically increase consumption of BCAAs.
Per NIH ODS, many foods contain protein, including meats, poultry, seafood, eggs, dairy products, beans, and nuts. ODS notes that complete proteins (containing all EAAs) come mainly from animal products such as meat, poultry, fish, eggs, and milk, whereas some plant proteins are incomplete (for example, soy lacks methionine and rice lacks isoleucine), so a combination of plant-based foods with complementary proteins that together provide all EAAs can supply them. ODS does not give per-food protein gram amounts in this fact sheet.
Per NIH ODS, the Food and Nutrition Board has not set a Tolerable Upper Intake Level for protein, noting that the risk of adverse effects from excess protein from food is very low; ODS advises caution for those obtaining high protein intakes from foods and supplements because of limited data on potential adverse effects. ODS reports no safety concerns at daily recommended intakes for athletes of up to about 2.0 g/kg body weight (about 136 g for a 150-lb person) and lists no known adverse effects for protein at these intakes. ODS frames athlete protein needs at about 0.55 to 0.9 g/lb body weight (1.2 to 2.0 g/kg) per day, generally obtainable from food. ODS adds that high-protein diets providing two to three times the RDA (0.8 g/kg/day for adults) do not appear to increase the risk of renal stones, dehydration, or compromised renal function.
