Have you ever wondered why dairy bothers you even when you take lactase pills, or why some people can drink milk without a problem while you experience immediate symptoms?
The truth is, it’s not just about lactose. Your genes play a major role in how your body responds to dairy, and the reason might not be what you think.
In a recent Q&A, Dr. J Dunn unveiled the brand-new Dairy Tolerance Slider, a powerful new addition to your MyHappyGenes® report that helps you finally understand your unique relationship with dairy.
The Two Types of Dairy Sensitivity
Most people assume dairy intolerance is all about lactose. But there are actually two completely different biological mechanisms, and your genes determine which one affects you.
Lactose Intolerance
This relates to your body’s ability to produce lactase, the enzyme that breaks down milk sugar. It’s a digestive issue that often worsens with age as lactase production declines.
Cow’s Milk Protein Sensitivity
This has nothing to do with lactose. It’s an immune system reaction to the proteins found in cow’s milk, which can cause inflammation and other systemic symptoms.
Lactase pills can help with lactose digestion, but if your issue is protein sensitivity, they won’t make a difference.
What You’ll Learn in the Video
In this educational Q&A, Dr. J explains:
- The specific genes that control lactose digestion and milk protein reactions
- Why lactase supplements don’t work for everyone
- How MyHappyGenes® calculates your personalized dairy risk score
- The difference between digestive and immune-based dairy reactions
- Why your heart rate might speed up after eating dairy
- The link between dairy and skin conditions like eczema
- Whether A2 milk or goat/sheep dairy may be better options for you
- How to recognize your body’s unique feedback signals
The MyHappyGenes® Difference
Here’s what makes this update groundbreaking:
If you’ve already taken the MyHappyGenes® DNA test, the new Dairy Slider is already in your report.
You don’t need to purchase a new test or pay any additional fee. As new research emerges, your results automatically update, giving you continuous access to the latest genetic insights.
That’s the power of the MyHappyGenes® dynamic genetic platform. Each time Dr. J and her team uncover new gene relationships or publish updated findings, those insights are added directly to your personal report.
Your investment in genetic testing continues to grow in value over time.
Recognizing Common Dairy Sensitivity Symptoms
Dairy reactions can extend far beyond digestion. Dr. J outlines how symptoms may appear across multiple systems:
- Digestive: bloating, gas, diarrhea
- Skin: eczema, rashes, inflammation
- Cardiovascular: elevated heart rate or blood pressure after eating
- Energy: fatigue or sleepiness after meals
- Immune: delayed inflammatory responses appearing hours or days later
Identifying which symptoms you experience can help pinpoint whether you’re reacting to lactose, protein, or both.
Practical Alternatives
Dr. J and GC also discuss practical solutions for managing sensitivity, including:
- Oat, nut, and seed-based milk alternatives
- A2 milk, which contains a different casein protein
- Goat or sheep dairy, often better tolerated by some individuals
The key is finding what works best for your genetic makeup.
Your Body Is Talking — Are You Listening?
One of the most powerful insights from this discussion is learning how to interpret your body’s feedback. Changes in heart rate, skin reactions, or energy levels aren’t random, they're data.
When you combine genetic knowledge with real-time body awareness, you create a truly personalized nutrition strategy that supports your unique biochemistry.
