  • Helps enhance fat loss when combined with diet and exercise

  • Helps you feel less hungry throughout the day

  • Helps maintain lean muscle mass
New Opti-Whey from Swanson Best Weight Loss Formulas features two uniquely effective dietary ingredients combined to help you lose fat and build muscle. Prolibra, a unique whey protein isolate combined with an active whey mineral complex, is an engineered designer protein developed to help accelerate fat loss and maintain lean muscle mass in people participating in a diet and weight loss program. PGX is an advanced blend of three soluble fibers that produce, with just a small amount of material, the same benefits that much larger amounts of traditional fibers do. And PGX causes no gas or bloating. Opti-Whey provides a pure blend of these two advanced ingredients with no flavorings, colorings or additives of any kind.

Don't waste your money. I normally do not write reviews but felt I must on this product. I am normally extremely happy with the products purchased from Swanson. This is the first one that I am returning. It taste awful. I only tried it because of the 2 for 1 deal. Don't waste your time or money. Go for Swanson's premium Whey Protein Powder. It is a much better product that mixes well and tastes great. April 28, 2012
Has a little flavor - but still good I bought this to put in my juice (not store-bought juice, from a juicer) to add some protein. I didn't see anything that indicated a flavor, so I thought it was unflavored. I can taste a little bit of a sweet/vanilla flavor. It's not bad - my juice is slightly sweet anyway. The scoop it comes with it pretty big, so I might cut it in half next time. I can definitely see myself using this in coffee or a dairy beverage. I’ll buy this again, I just wish they’d point out that it does have a little flavor. April 18, 2012
Really Filling My husband & I really like this product. Based on some of the reviews on it's taste, I was reluctant to try it, but I don't find it any different than most of the other protein powders I have tried. This makes excellent smoothies. We blend with low-fat vanilla flavored almond or coconut milk, frozen fruit, flax meal & silken tofu or greek yogurt for a smoothie that gives you lots of protein and the PGX really fills you up all morning. We are happily re-ordering - we don't want to be without it! March 29, 2012
Great Product I am not sure why others are discrediting this product. I have used LOTS of protein powder products and this is by far the BEST I have used. I have bought the discount store brands as well as private distributor brands. I mix it with almond milk in a shaker cup and it mixes just fine. I have found no "chunks" in the bottom. It is filling and satisfying and a great meal replacement. March 29, 2012
Great for Coffee I do not know why others didn't like this. I used a similar product in my coffee and was sad when I could no longer get it, until I tried this. I brew my coffee and pour it into a shaker bottle with a shaker ball and 2 ice cubes and some flavored stevia and love it! You need to not use steaming hot beverages but if you like a warm protien this will work. It has no flavor at all so whatever you add it to is fine. I did not find it "chalky", sometimes slightly "gummy", but never bad. I love it. May 25, 2010
This product is great! I love this product. It is great for after a workout. And it makes great shakes. Just add some soy milk, banana for consistency, blueberrys, raw honey, etc. It makes a great meal substitute. March 26, 2010
Yuck! I gave this product a try because the reviews said ti wasn't chalky. This stuff was beyond chalky! I normally make a shake with almond milk and fresh berries in the blender and add protien mix, when i was out i used this- it was the grossest thing i have tasted in awhile. even the texture was scary, it was SO thick you could turn the blender bottle upside down and it wasn't budging. I tried it with extra almond milk and it was still undrinkable. Undrinkable! It makes my gut churn just thinking about it. January 3, 2010
Effective Product This is a really great product if you really want to lose weight but you seem to be able eat at any time, anywhere and even after a hearty meal. This product has made it so I don't want to eat again at least 2 hours after eating - but I've actually made it as long as 5 hours before I realized that I was actually hungry. I coupled this product with Capsimax Plus so I can't tell if it's the combo or the shake alone. There isn't much flavor by itself but I add some frozen fruit, low fat yogurt and some stevia to make a really enjoyable shake. It's definitely worth the cost. September 12, 2009
Best Protein choice they have This is a great choice. it is very filling, has the most grams of protien for the serving, and it has the calcium, we all need that. Have told everyone who uses supplements. July 16, 2009
The Best Protean Powder you will find Why is this the best? Because it is the only one I have found that does not have about a quarter to a third MSG--Monosodium Glutamate. MSG is what gives all the other protean powders their good taste. it has a strong "That's Good! I want more NOW!" impact. MSG hides under 30+ different names, like "hydrolyzed vegetable protein," "textured protein," "gelatin," and "calcium caseinate." MSG is also in nearly all prepared foods now-a-days because it sells. This protean powder does not have a great taste, but because it has no MSG, it is much better for you than nearly all the other protean powders. So just add it to something that has a good flavor. June 25, 2009
The real thing! the only product I know of that lets you keep (or even build) muscle while helping to loose body fat. One down side is you have to mix it with somthing to help with the poor taste. April 22, 2009
Perfect diet aid When I am dieting, I want the highest quality nutrition with the lowest fat and calories. It is always nice if it tastes good too. This product fits the bill ... high quality nutrition, low calories, no fat, mixes completely with my choice of beverage for great taste! March 31, 2009
Not tasteless..... Unless you load your drink up with lots of fruit and splenda, you can really taste this. I wanted to mix in V-8 and ice and it was AWFUL. It is filling - the only way I can stomach it is with a whole banana, skim milk, and some sugar free chocolate syrup. This defeats the purpose of having a low sugar/low carb shake as the banana is loaded with sugar. March 21, 2009
Do not puchase this product This product did not mix well. The mixture was chunky. The taste is just awful. March 10, 2009
Will not purchase again I was unhappy with this product because it was too fine of a powder which allowed it to fly away whenever I measured it or dumped it into a recipe. I like the Swanson Whey Protein w/AminoGen much better. I haven't noticed any difference in taste, etc. and it is cheaper. December 22, 2008
Best of its type that I've found lately Many years ago I used a similar product for weight reduction, but it went off the market, and I could find no equivalent product. It came with supplements: vitamins, KLB6-cider-vinegar, and an EFA-rich oil to be added to the "milkshakes". It worked great, but when it disappeared... The national name-brand weight-loss beverage was never as good, and has gotten even less appealing. What to do? The solution came in the form of Opti-Whey, granulated lecithin and EFA Walnut Oil from Swanson, and some KLB6 tablets. Some pleasant flavorings and artificial sweetener complete the picture. The pounds are coming off, my energy level is better, my sleep is more consistent, and it's about as enjoyable as a diet ever gets! July 16, 2008
Super product This product does what it claims to do, and is more cost effective than other weight loss formulas I have tried. This one comes in at approx 99 cents/serving, whereas the one I was using before was $1.50/serving. The thing I like the best about this product is it really does make me feel full, I have no hunger pangs at all! I mix Vanilla Silk (soy milk) with frozen rapberries and a banana, or Chocolate Silk with ice cubes and banana. Both make a delicious shake, right around 220 - 300 calories each. August 13, 2007
Great stuff Put a little fat free milk in a blender, some Splenda or sugar free flavoring, add frozen fruit Strawberries are good, mix untill fruit is mashed and it likes like a milkshake. Tastes really great and it fills you up. June 29, 2007
Does What It Says! I love this product! I've been without for a few days and am not losing inches and feeling full like I was when taking this daily. These are the best results I've ever had from ANY protein powder. My favorite mixer for it is 8th Cont Lt Choc Soymilk. Juice with it is gross, don't try it. June 20, 2007
