Optimum Nutrition is known for making high quality supplements at attractive prices. Their 100% Whey Protein powder has become the gold standard for athletes and the benchmark that other protein powders measure themselves against. So, how does Optimum Nutrition's Oats and Whey stack up?

All Natural

Unlike almost every supplement out there, Optimum Nutrition Oats and Whey is 100% natural. There are no artificial flavors, sweeteners, or colors used. This means your body doesn't have to expend energy trying to digest or rid itself of processed, unnatural ingredients. This is especially beneficial to athletes who need to feel and perform their best, day in and day out. Oats and Whey also has a natural taste as a result -- not overly sweet or "fake" tasting, like some supplements.

Protein Content

Optimum Nutrition Oats and Whey has 24 grams of whey protein per serving -- mostly whey protein isolate with some concentrate. This is the same type of high quality protein that ON uses in their flagship 100% Whey Protein Gold Standard. It boasts an impressive amino acid profile with 8 essential amino acids (EAAs) and 6 conditionally essential amino acids (CAAs), including over 4 grams of Glutamine and its precursors. The protein in Oats and Whey has everything you need to recover, repair, and build lean muscle tissue. At 24 grams, you are getting all the protein you need for a 1 hour, rigorous workout. Anymore is just overkill.

Carbohydrate Content

Oats and Whey has 23 grams of carbohydrates, including 4 grams of fiber and 9 grams of sugar. These carbs come from the oats rather than refined sugars and are high quality. The complex carbohydrates will provide the slow burn your muscles need to recover while the sugar will help replenish glycogen immediately post workout. This carb blend is great for the average person, or for someone who has trouble cutting fat. If you are someone who has trouble adding lean mass, you may want to opt for a supplement with a higher carbohydrate content or consider mixing with skim milk instead of water.

Taste and Blending

As you can expect with any Optimum Nutrition supplement, Oats and Whey tastes great. The fact that it is all natural gives it an even better taste. It is not overly sweet, but not chalky either. The chocolate tastes like chocolate and the vanilla tastes like vanilla -- what a welcome surprise for a whey protein supplement! The taste is further improved if you blend with skim milk instead of water.

Oats and Whey blends extremely well, one of the best blending supplements I've seen. Stirring with a spoon leaves virtually no clumps of any size and a shaker bottle leaves no powder remnants of any kind.


Optimum Nutrition Oats and Whey is an extremely effective post workout supplement.  One serving will provide you with everything you need to recover from an intense, 1 hour workout.  I recommend 1 serving per each hour of rigorous exercise.  You will feel a noticeable difference not only after your workout, but the next day as well.  

As with any supplement, Oats and Whey is not a magic bullet.  It should be taken immediately post workout to help your body recover and used in conjunction with a solid diet.  Remember, supplements are great for recovery and providing some nutrient assistance, but you will not make lean gains without an adequate diet.


Overall, Oats and Whey is one of the top whey protein products on the market. Optimum Nutrition has done a great job by making it all natural and including not only high quality protein, but high quality carbohydrates as well. The combination makes for a potent, post workout recovery supplement. You know a supplement is legitimate when you can actually feel a difference. You feel the difference with Oats and Whey. The only improvement that could be made is the addition of more carbohydrates, but it's a very minor gripe, one that can be remedied by mixing with skim milk.

      This is a really great in-depth review. I think it's really important people are aware of the supplements they are considering before they actually consume them.
