Is Buttermilk Healthier than Regular Milk?

Both buttermilk and regular milk are incredibly similar in their nutrient content, meaning they’re both quite nutrient-dense options.

Buttermilk tends to have slightly less calories and less fat than regular milk, but even that can vary wildly depending on the different brands of buttermilk out there.

For this specific vegan buttermilk, you’ll be getting the following great health benefits:

  • Excellent source of essential vitamins and minerals like calcium, potassium, and vitamins A, B12, and D.
  • The same amount of protein as regular milk but with far less calories from the soy milk.
  • It may even help to protect against heart disease thanks to flavonoid antioxidants found in the lemon juice. (1)

Can I Freeze This Vegan Buttermilk Substitute?

One of the great things about buttermilk is that it just so happens to freeze quite well. This is actually pretty handy, especially if you seldom use it in your recipes and you don’t want it to go bad in the fridge before you need to use it again.

If you want to freeze your buttermilk, just make the recipe as normal and wait for your mixture to sit for 10 minutes. Then pour the buttermilk into an airtight, freezer-safe container before keeping it in the freezer.

When frozen like this, you can expect this vegan buttermilk to last for up to 1-2 months.
