Rating: We Avoid
- 1 out of 5
Ingredient Score:

Rated at 1/5 green leaves, Optimum Nutrition Serious Mass – Chocolate Peanut Butter is a product that falls short in providing a cleaner food option for health-conscious consumers. The mass gainer supplement, designed to aid in weight gain and muscle building, fails to meet the criteria for a healthy and organic product on our scale.
The absence of organic certification results in an immediate deduction in its rating, reflecting concerns over the potential presence of pesticides and other chemicals in non-organic ingredients. The product also does not use non-GMO ingredients, raising further questions about the quality and sourcing of its components.
A significant issue with Serious Mass is the inclusion of added sugars, especially artificial sweeteners like Acesulfame potassium and Sucralose. These ingredients are often associated with adverse health effects and contradict the aim of cleaner eating. Additionally, the presence of potentially harmful additives, such as natural and artificial flavors, soy lecithin, and modified food starch, contribute to the low score, suggesting that the product may contain unnecessary chemicals that could be avoided.
Maltodextrin and artificial flavors are particularly concerning, as these are known to be harmful additives. Maltodextrin, a highly processed carbohydrate, can spike blood sugar levels, while artificial flavors are synthetic and may have unknown long-term health implications.
The inclusion of artificial flavors is also problematic, as these ingredients are often linked to negative health outcomes. The product’s reliance on such flavors detracts from its overall quality and purity, which is a critical factor for individuals seeking healthier food alternatives.
Optimum Nutrition Serious Mass – Chocolate Peanut Butter is not recommended for those looking to maintain a clean and healthy diet. The product’s low green leaf rating reflects its composition of questionable ingredients, non-organic status, and use of GMOs. Cleaner alternatives with higher green leaf ratings are available and preferable for consumers aiming to support their health and wellness goals without compromising on ingredient quality.
