Boron is a mineral with no dietary recommended amount and there has been little research on it. It may be requred in tiny amounts in the diet but it’s abundant in plant foods.
However, it’s been requested twice - as far as I know - that we provide an amount of boron for Huel. So I looked into it…
The amount is around just less than 1.5mg per 2,000 calories which covers the typical intake range of 0.87 to 1.35 mg/ day for adults. It’s also well under the safe upper limit of 20mg per day.
Hope this helps
