Differences between whey and isolate?

The primary differences between whey protein and whey protein isolate are:

1. Lactose Content:

   • Whey protein contains more lactose compared to whey protein isolate, which has most of the lactose removed. This makes isolate a better option for those with lactose intolerance.

2. Processing:

   • Whey protein isolate undergoes additional processing to remove fats and lactose, resulting in a higher protein content (around 90-95%) compared to whey protein concentrate, which contains about 70-85% protein.

3. Immunoglobulins:

   • Whey protein concentrate retains more of the beneficial immunoglobulins and other bioactive compounds like alpha-lactalbumin and lactoferrin, which may offer added health benefits.

Both types of protein help in delivering essential amino acids that are necessary for muscle synthesis. Whey protein isolate is generally preferred for individuals with lactose sensitivity or for those looking for a higher percentage of protein per serving 1.
