Formulation & Product Questions

In terms of the amount of protein shakes per day, there is no absolute figure as this depends on your protein intake from food. You should aim to consume the majority of your protein from food and then use a shake as a convenient way of topping up your intake. Your protein intake should vary between 1.4-2g/kg body weight to support performance, going towards the higher end if you are aiming to build muscle. Also to support recovery and performance  your protein should be evenly spread across the day, aiming for 20-30g of protein at each meal. There is no best time to take a protein shake as it can be taken at any time throughout the day but a protein shake after a workout is a good option as it provides the muscle with a high quality protein source which is delivered to the muscles fast after exercise.

Optimum Nutrition was the first brand to bring powdered casein to the market and continues to be one of the only brands to offer micellar casein as its only source of casein in this product. Micellar casein is the only slow digesting casein other caseins such as calcium caseinate are not slow digesting and have a similar digestion rate to whey protein.

Gold Standard 100% Plant is a mixture of pea and rice protein, the combination of which makes it a complete protein. Rice protein is high in cysteine and methionine but low in lysine whereas pea protein is low in cysteine and methionine but high in lysine, therefore combining these proteins provides you with a full complement of both essential and non-essential amino acids which will support the growth of lean muscle mass, particularly as it contains a leucine content of 2g.

The bloating you experience with whey protein may be due to the lactose in the product, which is a naturally occurring sugar in dairy products. Plant protein does not contain lactose so it may help with this issue.

Optimum Nutrition protein products including Gold Standard 100% Whey contain complete high quality protein sources. This means that they contain all 20 amino acids - which are divided into essential (not produced by the body and are required from food in the diet) and non essential (produced by the body and not needed from food in the diet) amino acids.   It is well understood though that a complete protein with all 20 amino acids is needed to support muscle growth and maintenance.

The bloating effect caused by creatine is due to water retention and is an individual response. We would only recommend creatine monohydrate as it is proven most comprehensively by science.

The soy lecithin is a part of the initial blend of BCAA which we use to make up the amino energy product so the amounts in the product are at trace levels, there is maximum 1% added to the BCAA blend, so there would be maximum 20 mg of soy lecithin per serving. It is added to the product to allow the product to be better dispersed when liquid is added.

Gold Standard Whey protein uses ultrafiltration and ion exchange processes to produce a superior product which supports training goals. These processes do denature the protein, however this does not affect the proteins ability to support muscle growth and maintenance after training.  In fact cooking and the digestion process also leads to denaturation.

We produce products for multiple countries and therefore our labels must be compliant in each country. We reduced the dose in ZMA to 1 capsule for consistency across all of Europe as  advising to take 3 capsules daily was outside the upper limit for the daily recommended intake (RDI) for some countries in mainland Europe, particularly for zinc. In some of these countries the upper limit for the RDI for zinc per day is 25mg and 3 capsules of ZMA would exceed this dose as it provides 30mg.

For the EU we declare calories based on the protein, carbohydrate and fat values delivered from the flavours and other ingredients, but as a food supplement they are not declared on the front or back of the pack only the calories linked to them. The US may declare these differently which may cause the slight difference between the varience on pack.

The phrase ‘contains a source of sugar’ is a mandatory statement associated with Isomaltoligosaccharides (IMO) as it has an effect on your blood glucose levels. However the primary role of IMO is for bulking properties as well as being a fibre source, it is not added as a source of glucose.

The recommendation for meal replacements is to use 1-2 a day to replace meals, as part of a diet which includes food. There is a mandatory statement in relation to MR products which states; 


“The product is intended only as part of an energy-restricted diet and that other foodstuffs should be a necessary part of such diet.” 

 

From a nutritional standpoint, these products are complete/balanced, but we cannot go against the mandatory regulatory dosage and consumption advice. Plus, considering these are only ~200 kcal, if you were having one for each meal, that’s only 600 kcal a day, which is a bit extreme. Therefore we recommend that these products be taken in place of 1 or 2 meals, and other food should still be consumed.

The main advantage of Gold Standard Isolate is that it is 100% isolate compared to Gold Standard Whey which contains both whey protein isolate (WPI) and whey protein concentrate (WPC) in its formulation and therefore has a higher percentage of protein and a lower level of carbohydrate, lactose and fat per serving. Gold Standard Isolate has 30g of protein per serving whereas GS Whey has 24g per serving, so depending on how much protein you need daily or want to hit in one serving you may prefer to choose one over the other. However, both protein powders support muscle growth and repair effectively.
