                                A study found that butter from grass-fed cows contains significantly higher levels of beneficial fatty acids, including omega-3s, compared to butter from grain-fed cows. This key finding reveals that a cow's diet, rather than its A2 or A1 protein type, is the primary driver affecting a butter's omega-3 content.
