Question

Can I mix L-Ascorbic Acid (Vitamin C) Fine (10g) and L-Ascorbic Acid (Vitamin C) Ultra Fine (40g) in a 50g formula?

What is the difference between the Fine and Ultra Fine types of Vitamin C?

Answer

Based on the staff's reply, you can mix LAA fine (10g) and LAA ultra fine (40g) in your 50g formula.

The staff explained that both types of L-Ascorbic Acid (fine and ultra fine) are the same when fully dissolved in water. The difference in particle size only matters when the Vitamin C is not completely dissolved or when there is very little water, in which which case the ultra-fine type dissolves more easily.

Therefore, as long as your formula ensures that the total amount of Vitamin C (50g) is completely dissolved, using a mix of fine and ultra fine should not cause any issues.
