Sadly this product is not available without the rice flour. **Q: i see the capsules are 500mg, but what is the strength of elemental magnesium per capsule, as this is what counts towards the RDA ?** A: The Magnesium L-Threonate that I take is 2000 mg containing elemental magnesium of 144mg per serving, estimated as 34.29% of the daily value. A serving is 4 capsules. Therefore each capsule contains presumably 36mg of elemental magesium. **Q: Is it 2000mg per capsule or 4x 500mg per serving?** A: hello. it’s 2000mg per serving not per capsule. yes, you are right, 4x500mg, if you will look it that way. **Q: Is vegetarian the capsule or made of bovine?** A: Hello, It is made with Gelatin (capsules) which is not Vegan but from animal skin ## Customer Reviews ### ⭐⭐⭐⭐⭐ Best Magnesium supplement *by H***Y on 26 April 2025* This is the finest magnesium supplement I have ever used.
