A2 milk's mixed impact on bloatingThe Effect of A2 Milk on Gastrointestinal Symptoms in Comparison to A1/A2 Milk: A Single-center, Randomized, Double-blind, Cross-over Study.
We aimed to understand how different types of milk affect bloating, particularly focusing on A2 milk versus regular A1/A2 milk. In this study, we conducted a randomized, double-blind, cross-over trial with 40 participants who reported experiencing gastrointestinal discomfort after consuming milk.
Over two weeks, each participant consumed either A2 milk or A1/A2 milk, separated by a two-week washout period. Using various assessments like symptom rating scales and digestive symptom questionnaires, we examined the effects on bloating and other gastrointestinal symptoms.
Our findings revealed that A2 milk did increase reports of bloating and loose stools compared to the A1/A2 type. However, participants also indicated experiencing less abdominal pain and urgency when consuming A2 milk. Interestingly, fecal calprotectin levels were less elevated after consuming A2 milk, particularly in males, suggesting that A2 milk may help alleviate some digestive discomfort.
Overall, while A2 milk was associated with less abdominal pain and urgency, some individuals did experience increased bloating. Despite this, the study didn't report any significant adverse effects, suggesting that A2 milk could be a viable option for those with mild digestive issues related to milk consumption.

New 'favourite' Casein. Surprised me! I decided to switch back to Dymatize! It's cheaper per pound than the Optimum Nutrition Casein I've used for years and packs more BCAAs, which helps with protein synthesis. The flavour is pleasant and it's very low in carbohydrates—only 2g. It mixes nicely, but I generally need about 2 cups of milk to achieve the right consistency; otherwise, using water results in a thicker texture. I find that it does its job effectively; I feel less hungry in the morning when I take it, leading to reduced soreness. I also don't experience any bloating, although minor gastric issues may arise if taken too soon after eating. Best taken on an empty stomach before bed.
