Suggest The Ideal Dosage For NAC
Question: I am a 21 year old woman suffering from symptoms of both PCOS and OCD condition. I bought 600 mg of NAC (N-Acetylcysteine) supplements for these conditions (since I've heard that NAC is helpful in reducing the symptoms of both the conditions). Also I am a bit overweight (I weigh about 74 kgs to 80 kgs). So my question is how much dosage of 600mg of NAC should I take despite my weight of right now?
Brief Answer:
Consultation
Detailed Answer:
Hello, and thanks for your question.
For OCD, doses of NAC that have been used in case reports on the subject recommend going as high as 3000mg daily. However, this needs to be uptitrated carefully to avoid side effects of too much NAC too quickly. I recommend starting with 600mg, and increasing by 600mg weekly until you arrive at a maximum dose of 3000mg. In other words:
Week 1: 600mg
Week 2: 1200mg
Week 3: 1800mg
Week 4: 2400mg
Week 5: 3000mg
