Amazing sleep support
I’ve been using the 3-in-1 Magnesium L-Threonate, L-Theanine & Apigenin supplement for a few weeks now, and the difference in my sleep has been incredible. I fall asleep faster, stay asleep longer, and wake up feeling genuinely refreshed—not groggy like with other sleep aids. The blend is perfect: Magnesium L-Threonate helps me feel mentally clear the next day. L-Theanine gives me that calm, relaxed feeling before bed. Apigenin seems to deepen my sleep in a way I can actually feel. I’ve also noticed a nice boost in my overall mood and focus, which was an unexpected bonus. The quality is excellent, and I love that it supports both sleep and cognitive wellness. Absolutely worth it—this is staying in my nightly routine!

Dream a little dream...
I take one capsule before bed, and i dream away. I dont see the need for 3 caps. I think its the Apigenin in it that helps with dreaming, as i have that on its own too with the same effect. But yeah, go for it.

Did not work
I bought these as the ingredients matched another I take which work really good and these were a cheaper alternative. Sorry to say they don't work despite having the same contents. So I will be paying extra for something that does work. Hence these are very large capsules and taking 3 is an effort.
