Oxalate Content of Plant-Based Milk

This is a quick but essential update on milk. Plant-based milk, that is. 

A new study takes a look at the oxalate content in various brands of milk—you can see the results in the pretty little graph that we created below. 

You’ll see that the dairy milk studied was lactose-free. You’ll also notice that researchers noted a teensy bit of oxalate. I suspect this is do to the cow grazing on grass (along with some soil) all day and that this is where these trace amounts come from? I am giving it my best guess!

Keep in mind that researchers can’t necessarily study every single plant-based milk on the market. It’s certainly possible that you’re using a different brand with varying levels of oxalate, but life is too short to worry about the small discrepancies of every coconut or pea milk. Use the brand you like, stay away from the highest oxalate ones like almond milk (which you already knew).

Along with the oxalate content, this graph provides the potassium, sodium, and calcium content for each beverage. Remember that potassium and sodium are especially important considerations if you have Chronic Kidney Disease.

You can read a snippet of the article here. The full article requires payment, I’m afraid.

      Hi Debbie,
      Peas are low in oxalate so not worried about the different brands. Enjoy!

    For a person with high calcium in urine and kidney stones, does drinking plant based milk fortified with calcium increase kidney stone risk similar to calcium supplement?

        Hi Jill! The implication from your answer is that plant milks fortified with calcium are better than calcium supplements in terms of getting adequate calcium in the diet to bind with oxalate in the gut and not risking the kidneys. But I’ve never been able to understand this. I could see perhaps if the calcium supplement is a large tablet that doesn’t dissolve well in the digestive tract, then yes, this would be ineffective at preventing kidney stones. But how is, say oat milk fortified with calcium carbonate any different from adding a calcium carbonate powder to a smoothie? And I would think the same applies to Milkadamia brand macadamia nut milk that’s fortified with calcium phosphate: it seems you could get the same effect by just adding calcium phosphate powder to the drink of your choice. Ditto for calcium citrate, calcium aspartate, and a half a dozen other types of calcium. Of course, the particular form of calcium might indeed matter (I think the debate rages on on which is best for “bioavailability”), but I still have to believe that “rolling your own” calcium fortified drink can be just as effective as buying a pre-fortified one. Why am I wrong?

          Hi John,
          One can assume you can do that. The very best calcium is from dairy. But I understand many do not want to or cannot use dairy products.

    I am completely confused. What do you do if you are plant based and deal with gastritis as well?

    Thank you for this information! I’m severely lactose intolerant and learning how to adjust my diet to avoid additional kidney stones.

    Is there an amount of oxalate that is ok or should we avoid almond milk altogether?

    Hello,

    The “OXALATE CONTENT of PLANT-BASED MILK” has some MAJOR lacks regarding the proper info!

    1. Missing a column for phosphorus (vital info missing), some plant-based milks having shockingly HIGH phosphorus levels/values!

    2. Missing a column for sugar (vital info missing)! Many people who are looking for plant-based milks do so due to diabetes, so not including levels/values of sugar in plant-based milks conceals info on what is a life-&-death decision!

      Hi Raul,
      Because it was oxalate that was being reported on, not those other values. Please ck your labels for nutritional info for the medical conditions you are dealing with.

    I believe the chart is mislabeled. The calcium column is labeled in mg/cup but the values are in %. Which is correct? % of what?

    Hello Jill:

    I had a kidney stone passed once and I drink an unsweetened almondmilk/coconutmilk blend, brand name is Almond Breeze (Blue Diamond). I didn’t see this brand on the Oxalate Content of Plant Based Milk list. This item is sold at Whole Foods and many other stores and I was wondering what the oxalate content is. By the way, the above flavor I use is fortified by calcium carbonate – 35% DV per cup.

    – Thanks, Robert

      Hi Robert,
      Any almond milk will have some oxalate. Choose the plant milk that we know are lower!

    Hello, just wondering, if almond milk has oxalates and it’s made into a fortified milk with calcium carbonate, would that kind of cancel each other out? I’m currently drinking Kirkland unsweetened almond milk and it’s fortified with 600mg of calcium carbonate. Does the calcium cancel out the oxalates? Even while in the bottle? Thanks!

      Hi Danny,
      We ask that you give almond products up. Try Ripple pea milk or any other plant based milk that is lower in oxalate.

    Not sure you used percentages with calcium under the heading of mg…

    I also don’t know why your numbers are so low. A google search for ox’ in soymilk rendered 336 per cup. you say it 10. What a difference. The almond milk I buy says that it has 450mg of calcium, wouldn’t that wipe out all the oxalate? Lotta contradictory info.

    The chart in your plant-based milk article has sodium, calcium, potassium, and mean oxalate….all in mg/cup measurements in their respective headings. Yet in the calcium column the values are given in %’s. Is that the % of RDA for calcium in a normal diet…or kidney diet…?? A little confusing.
    Than you.

      Hi Chaz,
      Because that is how calcium is reported and that is based upon RDA not kidney stone diet.

      I would not use any type of almond milk as a stone former. No, it has not been studied so I do not know.
