Upset stomach

Decided to go on a more natural and healthier source of protein which lacks amount of protein in general compared to whey however I feel like I needed a change as I had been using the Whey protein and mass gainers far too much.

This product is great if your looking for a healthy alt to the whey isolations and Soy boasts other good benefits in immunity and general health such as vitamins and minerals as well. Whey is of course concentrated from dairy product and I think I needed to stop getting so much dairy in as well because I had been an avid milk drinker as well so for now to lighten the load of dairy for the past two months I had to decrease the amount of it by stopping whey and taking on soy protein for the last two months.

Overall this product is great no side effects and the only differences is that it may upset your stomach at times as you need quite a bit of it to get a good amount of protein into your diet... however its good soy protein and just a natural way of your body to take on the load of protein and pepsin releases from the gut. It also seems to full you up less than whey but a very minute difference in that department too as I felt a bit bloated at times when drinking a good two to three scoops of this stuff in my skim milk shakes.

Taste		Chocolate taste bad to me
Taste		but vanilla bean was better so I think that will be my go to flavor.


Taste		but we both thought it tasted great and mixed really well just like all other optimum products.


Muscle gain		however I wish they came in more flavors and larger sizes.
Taste		The flavor is not as rich as whey protein is and settles very well with the stomach.
Taste		however I wish they came in more flavors and larger sizes.
Mixes well		The protein mixes well with almond milk and water combo also with added glutamine and creatine it masks it very well.
Value for money		The price is very good


Taste		This stuff doesn't taste great,
Mixes well		but it mixes respectably and most importantly, it doesn't trash my stomach every time I drink it.


Texture		Dutch Chocolate is a little chalky,
Fat loss		But for losing weight, this product is the way to go.
Fat loss		I successfully lost 4 to 5 lbs with this product.
Taste		(if you mix a scoop with 8 oz of water) Taste : Vanilla Bean is terrible.
Taste		but it definitely taste good.
Mixes well		Mixability : very good !
Value for money		Price : Reasonable.
Value for money		(can find it a dollar cheaper in other on-line supplement store) Results : I don't know if it works for gaining weight.


Taste		The Vanilla flavor tastes great, and like any Optimum protein, you get results.


Texture		Chocolate is just a bit too chalky like for my taste.
Taste		Whey kills my stomach and so I was looking for a soy that was easily accessible (since I live abroad) and tastes great.
Taste		It tastes great and I really like it.
Taste		but I definitely think the vanilla is the better tasting of the two.
Taste		Chocolate is just a bit too chalky like for my taste.


Taste		But there's 2 downsides to this. 1, this tastes horrible.
Value for money		This product was cheap, as I got it half off.
Value for money		It did supply me with some good cheap protein.


Texture		I mix one scoop of each in milk using a hand-blender, and it comes out smooth
Texture		but not too thick and tastes great.
Taste		but not too thick and tastes great.


Taste		Well... i think that to say it is "dutch chocolate" flavor is offensive for the average dutch.


Taste		This stuff tastes AWESOME!! It's very mild in terms of flavor and sweetness.
Taste		This is the best protein powder I have tasted and I have no problems after having consumed a full serving.
Value for money		for quick shipping and great prices!


Texture		Horrible taste and a weird grainy/sandy texture.
Taste		Horrible taste and a weird grainy/sandy texture.


Texture		If you like your shakes thick, then this isn't for you.


Texture		My only complaint (which seems to hold true for all soy and not just ON's formula) is the gritty texture and difficulty mixing it.
Texture		The taste combined with the texture make it difficult for me to take without mixing it with something else flavorful.
Taste		The taste combined with the texture make it difficult for me to take without mixing it with something else flavorful.
Taste		I typically mix the strawberry flavor with some fruit juice, and I mix the vanilla flavor with diet root beer.


Fat loss		This will be great for women who are trying to lose fat or get very lean, sometimes I think it was made for the girls, But NOT for the boys who are constantly in the Gym day and day out training there butts off.
Muscle gain		(sight) Men, Beware, No matter how much Protein it is, it will hinder Muscle Gains thus results.
Strength		I didn't have energy Like I had while using other proteins wether powder or actual food, after 1 week of use, I was slow and I lost strength and I notice right away after the first week which led to a horrifying scene and a little bit of crying.
Physical energy		I didn't have energy Like I had while using other proteins wether powder or actual food, after 1 week of use, I was slow and I lost strength and I notice right away after the first week which led to a horrifying scene and a little bit of crying.
