Combining Apigenin with Melatonin: Did it Make Me Too Sleepy?

Posted by liam_sleepnerd in Safety & Side Effects - 4 points, 4 comments.

At the end of the week, I was trying to tighten my sleep stack by adding 3 mg of melatonin to my regular 50 mg nightly dose of apigenin. I kept track of HRV and bedtime latency in my log. The first night I dropped off the bed about 30 minutes earlier than usual, and the next morning I felt a lingering grogginess that persisted into the afternoon.

My HRV was slightly lower that night, and I noted an increase in heart rate upon waking. I gave it another week and the pattern repeated, sleep onset was faster, but the next day I was just “woke up from a nap” and had to sit a while before getting out of the chair. I stopped the melatonin for a few days, and my usual sluggishness after the apigenin returned to a more normal level. I’m curious if anyone else has tried the combo and what you’ve noticed about the additive sedative effect.

• sarah_c: I’ve played with a similar combo, and the pattern you’re seeing is pretty common. Melatonin at 3 mg can push you to hit lights‑out a few minutes earlier, and when you’re already on a high dose of apigenin it can create a “double‑dose” sleep drive. The lingering grogginess you felt – the rise in heart rate and lower HRV – suggests the parasympathetic tone is staying elevated into the morning. I found that shifting the melatonin to 2 mg or moving it to 30‑45 minutes before bed, instead of right a
• liam_sleepnerd: I took the melatonin just after my 50 mg apigenin, around 10:00 p.m. When lights-out. I’ll try your tweak, 2 mg 45 minutes before bed, and log HRV and wake‑up heart rate again. Do you notice any change in HRV when you shift the timing? Also, did you keep the same apigenin dose while experimenting?
• grace_sleepnerd: I took the 3 mg right at lights‑out, same as yours. The grogginess stuck around. I’ve cut it to 2 mg and moved it 30 min earlier, but the HRV dip and morning heart‑rate jump still show up. Did you notice a change in those metrics?
• liam_sleepnerd: Tbh I kept the 3 mg at lights‑out just like you and noted a HRV drop from 46 (~pre‑melatonin) to 39 that night and a resting heart rate of 78 versus 70 on the baseline day. The grogginess lasted overnight and into the afternoon, similar to your log. I didn’t try 2 mg yet, but I plan to shift to 60 min earlier and lower the dose. Did you see any change in apigeninvoz?
