Why We Don’t Use Additives or Amino Acids


Have you ever tried a supplement that is supposed to be good for you and benefit your health but found you had a negative reaction to it? 

You’re not alone, in fact this is a common issue for many customers taking nutritional supplements. At Designer Physique, one of our main points of difference is that our products contain no additives, amino acids or inferior blends. 

Our products are made from the purest, high quality ingredients with the entire formula (including flavours and sweeteners) being as natural as possible. You might wonder why a protein company would want to steer clear of inferior blends, additives and amino acids.

Aren’t amino acids supposed to be healthy and protein blends the current trend? While these are both valid points, Designer Physique’s products are a point of difference on the supplement market and for a very purposeful reason. 

Why we focus on providing clean supplements

The company’s founder, Tony Sfeir suffered from several food additive sensitivities and intolerances himself and found it hard to find high quality supplements without the low-quality additives that flared up his allergies. Find out more here about Tony Sfeir and how Designer Physique came into existence. 

The Designer Physique Difference

Our product design and purpose are simple, we avoid the ingredients and mixes of ingredients that can cause sensitivities and intolerances so that the supplements you eat can support health and wellbeing rather than cause harm like so many others. 

Our products do this primarily by avoiding dietary chemicals, not adding amino acids, and not blending together various proteins.

Why we avoid food additives 

Several studies and research have been conducted on intolerance reactions to food and food additives, although the prevalence of this is not clearly defined, literature estimates this rate at 5-20%, signifying a consistent percentage of people who experience intolerance reactions from food additives (Hayder, et al., 2011).

 Some of the main food additives commonly found in supplements include:

  • citric acid
  • dextrins/maltodextrins
  • artificial flavours
  • common artificial sweeteners such as sucralose, aspartame and saccharin. 

Research has shown that after ingestion of manufactured citric acid (MCA) several case studies experienced harmful inflammatory reactions such as joint and muscular pain, irritable bowel symptoms, respiratory symptoms and feelings of fatigue (Sweis & Cressey, 2018). Intolerance symptoms such as glucose intolerance that causes alterations to the intestinal microbiota composition (balance of good and bad bacteria in the intestines) can lead to gastrointestinal disturbances such as bloating or cramping and sweet taste receptor activation which activates the biochemical responses to do with glucose and carbohydrates from tasting sweet food. These disturbances and activations are found to be linked to consumption of artificial sweeteners (Ruiz-Ojeda, et. al., 2019). 

Our proteins don’t come in blends

Although the idea of a protein blend can be a great combination of all the best bits that each particular protein source has to offer, it certainly isn’t a better choice for everyone. 

Designer Physique’s protein supplements are each a pure form of protein that isn’t blended with other protein sources. You might be wondering why this is. 

Our products are purposely designed this way to cater to each customer’s individual sensitivities and intolerances. For example, it would be detrimental for a customer with a dairy or lactose allergy to consume a whey-based protein powder as it contains lactose, therefore a blended protein containing whey wouldn’t be an appropriate choice to fuel their body. On the contrary to this, WPI (whey protein isolate) contains less than 1% lactose, so this could still be an appropriate choice for someone with a mild intolerance, find out more about WPI and intolerances here. However, this customer may also have a sensitivity to pea protein, so although a lactose free protein blend seems appropriate based on one intolerance, it doesn’t cater to all their intolerances. 

Like Tony, there are many customers who experience multiple sensitivities and intolerances making it harder to find an appropriate supplement, as many that cater to one sensitivity may still set off another. That is the beauty of our non-blended protein sources. Between our options of whey, brown rice, pea, carob, eggwhite and soy there is an option to suit nearly any intolerance. 

This is important to us because we believe that everyone should be able to fuel their body with safe, high quality and non-reactive supplements. 


No amino acids are added

While supplementation of amino acids shows many benefits, for some people they can cause symptoms of toxicity or intolerance in the body such as nausea, headaches and pain. Amino acids can also interact with several medications including diabetes and thyroid medication and impact blood sugar levels (Takaoka, et. al., 2019)

As many protein supplements on the market contain added amino acids, by excluding these from our protein supplements we are able to once again cater to customers who experience intolerances and sensitivities to specific amino acids and provide them a safe protein supplement option. By having pure sources of amino acid supplements available as well, these can be safely added to our protein supplements to give a more comprehensive supplement alternative without the risk of triggers. See the table below for some pros and cons that can be experienced when supplementing with amino acids (Williams, 2005).
