I'm on day 3 of the KPAX Immune. I take 1 tab breakfast, 1/2 tab with lunch and will increase slowly if no issues arise. I have seen some energy improvement and even blood pressure increases but my diastolic is still low. pulse pressure today is 76. (125/50) . It's still very early in my trial of KPAX to know for sure how I'll like it but I'm cautiously optimistic.
