It’s kinda too soon for the candida to adapt to anti fungals. The grapefruit seed extract is just a stronger antifungal in general that’s y it could cause more die off. You should definitely be taking coconut oil because it’s harder for the candida to adapt to instead of the caprylic acid. Coconut oil has caprylic acid and lauric acid so it’s more beneficial. It also provides you with good fats that are hard to come by on this diet.
