Does Optimum Nutrition Serious Mass Have Lactose? Your Complete Guide for Lactose Intolerance

3 min read

Over 70% of the world's population is estimated to have some form of lactose malabsorption, making the dairy content of supplements a critical question for many users. For those asking, 'Does Optimum Nutrition Serious Mass have lactose?' the answer is definitive and important for your digestive health.

Quick Summary

Optimum Nutrition's Serious Mass contains dairy, specifically whey protein concentrate and sweet dairy whey, which both contain lactose. Those with lactose intolerance should expect gastrointestinal issues and need to consider suitable alternatives.

Key Points

  • Contains Lactose: Serious Mass is not lactose-free due to its protein blend which includes whey protein concentrate and sweet dairy whey.

  • Causes Digestive Issues: Individuals with lactose intolerance are likely to experience symptoms like bloating, gas, and cramps after consuming Serious Mass.

  • Whey Concentrate is the Culprit: The main source of lactose in the supplement is the less-filtered whey protein concentrate, unlike isolates or hydrolysates.

  • Look for Dairy-Free Alternatives: For lactose intolerant individuals, plant-based mass gainers or those using whey protein isolate/hydrolysate are better options.

  • Check the Label: Always read the ingredient list and allergen information to confirm dairy content, especially in products where 'dairy' isn't obvious.

Understanding Lactose in Mass Gainers

Lactose is the natural sugar found in milk and other dairy products. For individuals with lactose intolerance, the body produces insufficient amounts of lactase, the enzyme required to break down this sugar. When lactose is not properly digested, it can cause uncomfortable symptoms such as bloating, gas, stomach cramps, and diarrhea. The protein sources used in supplements are the main culprits when it comes to lactose content.

The Difference Between Whey Concentrate and Isolate

Mass gainers and protein powders often contain whey protein, which is a byproduct of cheesemaking. There are different forms of whey protein, each with varying levels of lactose:

  • Whey Protein Concentrate (WPC): Less processed and contains a higher amount of lactose compared to isolates. It is a primary ingredient in Serious Mass.
  • Whey Protein Isolate (WPI): More filtered, removing significant fat and lactose, making it easier to digest for lactose-intolerant individuals.
  • Whey Protein Hydrolysate: Pre-digested protein chains are broken down into smaller peptides. It contains even less lactose than isolate.

The Serious Mass Ingredient Breakdown

Optimum Nutrition Serious Mass is not lactose-free. The ingredient label lists a "Proprietary Protein Blend" with several dairy-based components. These include Whey Protein Concentrate, Calcium Caseinate, and Sweet Dairy Whey. The presence of these ingredients, particularly whey concentrate and sweet dairy whey, indicates a significant amount of lactose per serving, especially given the large serving size.

Symptoms for Lactose-Intolerant Users

Consuming Serious Mass while lactose intolerant will likely result in digestive issues, such as gas, bloating, abdominal cramps, and diarrhea. Even mixing the powder with lactose-free milk doesn't eliminate symptoms as the lactose is in the powder itself.

Lactose-Free Mass Gainer Alternatives

Several lactose-free options are available:

  • Plant-Based Mass Gainers: Utilize pea, rice, or soy proteins and are naturally lactose-free.
  • Mass Gainers with Whey Protein Isolate/Hydrolysate: Products, like Optimum Nutrition's Gold Standard Gainer, use more filtered protein types with lower lactose.
  • DIY High-Calorie Shakes: Create shakes with lactose-free milk or milk alternatives, lactose-free protein powder, nut butters, and oats.

Comparison Table: Serious Mass vs. Lactose-Free Options

Feature Optimum Nutrition Serious Mass Whey Protein Isolate Gainer Plant-Based Gainer
Primary Protein Source Whey Protein Concentrate, Calcium Caseinate, Egg Albumen, Sweet Dairy Whey Whey Protein Isolate, sometimes Hydrolysate Pea Protein, Brown Rice Protein, Soy Protein
Lactose Content High (Contains whey concentrate and sweet dairy whey) Very Low (Most lactose filtered out) None (Dairy-free)
Suitability for Lactose Intolerance Not Suitable Often Suitable (Check product labels) Very Suitable
Digestion Can cause stomach upset, bloating, and gas Generally easy to digest Typically easy to digest
Calories ~1250-1640 per serving (with milk) Varies by product, often lower than Serious Mass Varies by product

Conclusion

Optimum Nutrition Serious Mass is not suitable for lactose-intolerant individuals due to its significant lactose content from ingredients like whey protein concentrate and sweet dairy whey. This will likely cause digestive discomfort. Consider plant-based alternatives or those made with highly filtered whey protein isolate for a better experience. Always check ingredient lists and allergen warnings.
