Helps the memory!
This stuff is great! It's one of the few things that will cross the blood brain barrier, and keeps your memory all together! We had my mom on this for a long time, then she stopped swallowing her pills, so we pulled them from her (she would chew on them ... ick) and after that, we watched her go downhill quickly, sadly passing in the next year. When she was on them though, she was talking, answering, chatting, we could carry on conversations ... off them, we got nothing. As I'm semi-retired now myself, I have incorporated them in my routine and I can say it helps too!

Well-Formulated, Easy to Take, Subtle Benefits So Far
I’ve been taking this Phosphatidylserine 300 mg supplement for a period of time now and wanted to give a thoughtful review based on real use rather than short-term expectations. First, from a practical standpoint, the capsules are small and easy to swallow, which matters more than people realize—especially if you already take other supplements. No taste issues, no stomach upset, and no problem staying consistent. From a technical and clinical perspective, phosphatidylserine (PS) is a phospholipid that plays a key role in cell membrane structure, particularly in neuronal cells. It’s commonly used for: cognitive support (memory, focus, word recall) stress response and cortisol regulation age-related cognitive decline supporting communication between brain cells There’s research supporting its role in modulating cortisol, which is why it’s often used for stress management and mental fatigue, especially when taken consistently over time rather than expecting immediate effects. As for results, I’ve noticed slight but real improvements, mainly in mental clarity and day-to-day cognition. Nothing dramatic or overstimulating—and honestly, that’s a good thing. This doesn’t feel like a stimulant or a quick fix. The changes are subtle, steady, and cumulative, which is exactly how this type of supplement is supposed to work. I’m realistic about supplements like this: they’re not meant to produce overnight results. Because of that, I plan to continue using it for a few more months to see whether the improvements become more pronounced with longer use. So far, I’m satisfied with the quality, dosing, and tolerability. If you’re looking for a clinically supported cognitive and stress-support supplement and are willing to give it proper time, this is a solid option.

Terrific sleep aide!
SLEEP! Blessed sleep! This supplement was mentioned on the Freakonomics radio program by a doctor for use in overcoming jet lag as it suppresses cortisol. Wow, have only used it a short time but it has really helped me fall asleep and more importantly, stay asleep!

Helps with sleep and stress
Can’t live without this supplement. Lowers cortisol and helps with sleep and focus. I take one at bed time. I wake up much happier and able to handle the stress of existing during these unprecedented times. I definitely recommend this to as many people as I can.

Pros: • High-Quality Ingredients: The ingredients are clean, natural, and effectively sourced. • Boosted Mental Clarity: I noticed an improvement in focus and clarity after consistent use, which helped during work and study sessions. • Great Value for Money: You get a good quantity of capsules for the price, making it a cost-effective option for daily use. • No Side Effects: Unlike other supplements I’ve tried, I haven’t experienced any unwanted side effects like jitteriness or crashes. Cons: • Capsules are Slightly Large: While not a major issue, the capsules can be a bit large to swallow, especially if you’re not used to taking supplements. • Takes Time for Full Effects: You need to be consistent for at least a couple of weeks to notice the full benefits. Overall, I’m very satisfied with the quality and results from Double Wood Supplements. It’s a great addition to my daily routine, and I highly recommend it for anyone looking for a natural cognitive boost.

50% of the pills turn yellowish, less than 3 months after I open the bottle. I’m very careful of not touching the unconsumed pills. I do not get the consistent brain boost.
