Most people get nothing. The ones who do get something can usually trace it to one of 3 ingredients, and 2 of those are fixed by moving when you take it rather than by stopping.
I want to be careful here, because “side effects” on a supplement page is usually either a scare or a whitewash. This is neither. It’s a walk through the label, ingredient by ingredient, saying what each one is actually known to do to people and what to do about it.
So here’s what I’ll cover:
- The 3 ingredients that cause almost all reported problems
- Why “take it earlier” fixes more complaints than stopping does
- The interactions that are a pharmacist conversation, not a blog one
- What I’ve actually had happen
Rhodiola: the sleep one
There’s 50 mg of rhodiola rosea in a serving, and it’s behind more complaints than anything else in the bottle.
Rhodiola is stimulating for a lot of people without being a stimulant. Take it late and you get the specific, annoying version of insomnia where you aren’t wired, you just aren’t tired. I’ve done it to myself: a second serving at 4pm, then awake until 2am wondering what happened.
The fix is timing, not abstinence. Nothing after about 2pm. If that solves it, you never needed to stop taking it.
A smaller number of people find rhodiola makes them jittery in the morning too, particularly stacked on coffee. If that’s you, 50 mg is small enough that dropping to a single serving usually settles it.
Bacopa: the stomach one
Bacopa monnieri at 150 mg is the usual culprit for nausea, cramping or a loose stomach. This is well documented and it is dose-related.
Two things fix it. Take the capsules with food rather than on an empty stomach, which costs you a little absorption and is worth it. Or split the serving, one capsule in the morning and one at lunch.
The label asks for an empty stomach and there’s a real reason for it. But I’d rather you took this every day with toast than 4 days a week perfectly and then quit because you dread it.
- Rhodiola rosea50 mgSleep. Take it before 2pm and it usually goes away
- Bacopa monnieri150 mgStomach. Take it with food and it usually goes away
- N-acetyl L-tyrosine175 mgLittle on its own — but check thyroid and dopamine medication
- Citicoline250 mgMild headache in some people, usually gone inside a week
- L-theanine100 mgAbout as benign as an active ingredient gets

Tyrosine: the one to actually check
There’s 175 mg of N-acetyl L-tyrosine per serving. On its own, in a healthy person, it’s uneventful. Some people report a mild headache in the first week.
The reason it gets its own section is not the side effect. It’s the interaction.
Tyrosine is a precursor to thyroid hormone and to dopamine. So if you take thyroid medication, or an MAOI, or levodopa, or anything else working on those pathways, this is a conversation with your pharmacist before you start. Not a thing to work out from a blog, mine included. I’m not a doctor and I won’t pretend otherwise.
Same goes if you’re on blood thinners or antidepressants. One phone call, free, and it settles it.

What the rest of the label does
Citicoline at 250 mg is well tolerated at that dose. A minority report headache early on, which is common with choline sources and usually fades inside a week.
L-theanine at 100 mg is about as benign as an active ingredient gets. If anything it takes the edge off the rhodiola.
Phosphatidylserine, lion’s mane, maritime pine bark and the 3 B vitamins are quiet in my notes and quiet in the literature at these doses. The B vitamins can turn your urine bright yellow, which alarms people and means nothing at all.
What actually happened to me
Across the times I’ve run this, one thing recurred: a mild headache in the first 3 or 4 days, then nothing. And the 4pm insomnia the one time I stacked a second serving late, which was my own fault and entirely avoidable.
No stomach trouble, but I take mine with food, which is probably why.
The honest summary is that this formula is stimulant-free, sits at moderate doses, and the complaints it does generate cluster in exactly the places the label predicts. That’s not a defence of it. It’s what a well-tolerated supplement looks like, and plenty of them are not.

Conclusion
Rhodiola causes the sleep problems and timing fixes it. Bacopa causes the stomach problems and food fixes it. Tyrosine causes almost nothing but interacts with thyroid and dopamine medication, so ask a pharmacist first.
If something else turns up and it doesn’t fit any of those, stop taking it and see whether it goes away. That’s a real test and it costs you nothing.
That would be it folks. If you’ve had something I haven’t listed, put it in the comments with how long you’d been taking it. That detail matters more than people think.
