Product Overview

Platinum Hydrowhey was recognized by thousands of customers as 2010's New Supplement of the Year. What else would you expect from Optimum Nutrition's, fastest, purest and most advanced protein technology?

By hydrolyzing the protein in this premium formula we've created our most effective whey protein yet. Hydrolyzing breaks larger proteins down into smaller pieces that are used by the body to support muscle growth and maintenance. For added effectiveness, we've also enhanced this revolutionary formula with ACTITOR™ peptides, digestive enzymes and micronized branched chain amino acids (BCAAs). Platinum Hydrowhey is also ultra-pure because it's made entirely with hydrolyzed whey protein isolates. So there's no excess fat, cholesterol, or lactose to slow down your progress.

  • Made with Advanced Hydrolyzed Whey Protein Isolates
  • 30 Grams of Ultra-Pure Protein per Serving
  • Nearly 9 Grams of Leucine, Isoleucine, and Valine (BCAAs)
  • Includes Patent-Pending ACTITOR™ Peptides
  • Just 5mg Cholesterol
  • Contains Digestive Enzymes for Enhanced Utilization*
  • Instantized to Mix Easily with a Spoon


By combining the absolute finest ingredients with a series of highly specialized processing techniques Optimum Nutrition (ON) has created its most valuable muscle building protein yet. Everything about Platinum Hydrowhey® was designed with an uncompromising attitude toward performance - both in the gym and your shaker cup.


Platinum Hydrowhey® is protein in its purest expression. It's made only with hydrolyzed whey proteins that have been isolated to remove the excess lactose, cholesterol, carbohydrates, and fat. The result is a product that's ultra-pure and packed with protein to support muscle growth and maintenance.


100% of the proteins in Platinum Hydrowhey® are hydrolyzed to varying degrees. Hydrolyzing is a process through which intact proteins are strategically broken down into smaller fragments, called peptides, which may be easier to utilization by your body. ON's exclusive combination of mild, moderate, and ultra-hydrolyzed proteins provides di-, tri-, and oligo-peptides while retaining select microfractions naturally found in whey. If this is too much technical talk, all that you really need to understand is that Platinum Hydrowhey® is ideal first thing in the morning, before workouts, and immediately after workouts when your hard-working muscles benefit most from a hydrolyzed protein.


All proteins are made up of amino acids, but not all amino acids are of equal importance. The three branched chain amino acids (BCAAs) are particularly beneficial for athletes because they are bioligically involved with protein synthesis. That's why ON enhanced every serving of Platinum Hydrowhey® with added BCAAs for a total of over 8,800 mg per scoop which may assist protein with muscle building benefits.


The only way to reap the results of Platinum Hydrowhey® is to drink it. So from the outset, ON benchmarked the taste and mixibility against the best protein powders on the market. Regardless of whether you choose Turbo Chocolate or Velocity Vanilla, Platinum Hydrowhey® tastes as great as it works and dissolves easily in water, milk, or juice.


Try using complementary nutrients and mixing in other performance supplements to boost the functionality of your Platinum Hydrowhey® shakes.


Morning: Platinum Hydrowhey® shake + Opti-Men. Why? Your body needs vitamins and minerals to effectively use protein, carbohydrate, and fat.

Before Workouts: Platinum Hydrowhey® mixed with skim milk + Micronized Creatine powder. Why? Hundreds of clinical studies suggest creatine monohydrate's ability to boost physical performance during short-term, high intensity workouts. Creatine benefits obtained with a daily consumption of 3g.

After Workouts: Platinum Hydrowhey® mixed with iced coffee + Glycomaize + Glutamine Powder. Why? At no other time throughout the day are your muscles as receptive to nutrients as they are post-workout. So during this window support your hard work with a quality protein to promote muscle growth and help maintain all the muscle you have already earened!

Before Bed: Gold Standard 100% Casein + Instantized BCAA 5000 powder. Why? Whey proteins are beneficial during the day while you are active. But, casein is better at night. Casein proteins and BCAAs help protect maintain your hard earned muscle tissue throughout the night while you sleep.

HIGHLY RECOMMENDED! This is the best whey protein product I have used and have been using it for years. Great results. Velocity vanilla is also the best flavor as it pretty much can mix with anything. Delicious. I don't think I'll ever use anything else.

ONPH mixes well and doesn’t leave any clumps. It tastes great and is smooth once it’s all mixed. As far as seeing results, it helps maintain muscle growth and helps heal the soreness in just a few hours. Even when I don’t workout for a few days, I still maintain muscle density. This product digests well and doesn’t leave me gassy like other proteins, we’re all different so, this may be just for me. This s my post workout go-to protein. For pre-workout, it’s old school; one banana with natural peanut butter and 4 hard boiled eggs. I’m 48 years young and have to maintain muscle fibers at this age and ONPH does it for me. I’ve been taking this now for the past 6 years and don’t have any plans changing now. Thanks for a terrific product ON!

I use this for my post workout concoction. It blends very easy and is not clumpy. Taste is good and is easy to drink. It also easily blends with oatmeal unlike some other powders. Have had great results and this is a staple for me.

I've been using this protein for the past 2 months. Although I have never been as committed to the gym and my health as now I can definitely see the significant improvement on my muscle definition and growth. I know a big part of this is my diet but I can also see how much the protein affects, this supplies me with the right amount of protein that I need per day and to be honest the taste is absolutely delicious. I drink it with fat free milk because it gives me all the smoothie vibes and it's very tasty. Most other proteins I've tried before leave this lingering aftertaste that I really dislike, also the tastes were not what I expected. This particular chocolate one is absolutely delicious. I recommend 100%. Great product!!

I love the taste. This product doesn’t mess with my stomach and has 30 mg of Protein and all the essential BCAA’S. With cholesterol at only 10 mg not 5 as stated above, but only 20 mg of cholesterol is a huge advantage as a lot of Whey powders have 35-135mg. Their are only .5 saturated fat so it won’t dent the heart association guidelines of 16 grams per day. ON GoldStander was my fav till I switched to ON hydro Whey. Same amount of protein and w/the very low levels of Cholesterol and saturated fat I can fit 2 scoops of this for 60 mg of protein and still be in both my macros for the day and hit my protein per pound per day w/hydro whey and my chicken rice and peanut butter without worrying about fat (saturated) and cholesterol. Great product. I just wish they had creative in it but the price would count high and also I’d love a 5lbs tub instead of a 3.5 but hey this is my new favorite protein product

DO NOT purchase supercharged strawberry. It has a foul odor and an even worse taste. With that being said, hydrowhey is one of my favorite proteins. I would just recommend another flavor

So far, this is the whey protein that I've tolerated the best. I am lactose intolerant and VERY sensitive to even small amounts. I've had no issues with this protein and my recovery time is much quicker between workouts. The taste is great and it mixes extremely well in both water and almond milk.

I decided to switch up from Gold Standard Whey after not taking any protein for about a year, and I went with this Platinum Hydrowhey. This is by far my favorite protein powder that I've taken so far. It mixes easily in water and milk. I've mainly taken my shakes with Darigold 2% reduced fat milk, and the flavor is excellent with a light consistency. Best of all, I haven't had any issues with stomach aches or lactose intolerance like I had sometimes with Gold Standard. I've felt less sore after my workouts and my recovery time seems to be noticeably reduced compared to prior use. It's a little more expensive per serving than some of the other proteins out there, but I'd highly recommend it and say it's worth it!

Directions For Platinum Hydrowhey:

Platinum Hydrowhey® is INSTANTIZED, so it always mixes up easily and completely. Simply add 1 scoop of Platinum Hydrowhey® to a blender, shaker cup, or glass filled with 12 ounces of cold water, milk, or juice and blend, shake, or stir for 20-30 seconds or until powder is dissolved. TIP: Adjust the intensity of your Platinum Hydrowhey® shake by varying the amount of liquid you use to prepare it. For a slightly thicker consistency with a bolder flavor, mix each scoop with 10 ounces of water. For a milder tasting less sweet shake, use 14-16 ounces of liquid per scoop.

Stack Your Shake:By adding food supplements including creatine, BCAA, and carbohydrate powders you can make Platinum Hydrowhey® an even more powerful recovery product. TIP: Use Platinum Hydrowhey® during the day and more Gold Standard 100% Casein™ at night for more well-rounded amino acid coverage.

Suggested Use:Consume approximately 1 gram of protein per pound of body weight per day. Through a combination of high protein foods and protein supplements. For best results consume your daily protein allotment over several meals spread evenly throughout the day.
