Review: BSYNC-ON Wake Up Supplements

Quick disclaimer: I was gifted a pack of BSYNC-ON to try, but this is an honest review – if I think something is rubbish, I just don’t promote it!

If you want the TLDR version of this post, it’s this:

  • BSYNC-ON is a supplement you take at bedtime, which releases into your system right in time to wake you up in the morning without that groggy, sleepy feeling that normally lingers for a while
  • It really does work, although the clinical trials showed that it’s less effective in people who have a high caffeine tolerance, as caffeine is one of the four active ingredients
  • I’m a genuine fan, but I’ve had to stop taking it because I now have a prescription that doesn’t play nicely with caffeine
  • If you struggle to wake up in the morning, it’s definitely worth giving it a go to see if it works as well for you as it did for me

If you’re interested in finding out more, keep reading to get a more detailed low-down on what BSYNC-ON is, and what to expect if you take it yourself.

What is BSYNC-ON, and what’s in it?

BSYNC-ON is a delayed-release ‘wake up supplement’, and if you haven’t heard of one of those before, it’s because as far as I know, this is the first one. It’s made with vitamins B5 and B12, zinc and caffeine, and is formulated to release around seven hours after you take it. These supplements are vegan-friendly, gluten-free, sugar-free, lactose-free and non-GMO.

The idea is that if you take one of these as you’re turning the light off to go to sleep, you’ll get a good night’s rest in before it starts to release into your system, and once you hit eight hours from consumption you’ll wake up energised and feeling fresh.

I’m always dubious of claims made by supplement companies, but this one has been through a couple of clinical trials, as well as additional human trials in non-clinical settings, and the results have been really positive. The only exception is for people with a high caffeine tolerance – if you’re drinking coffee all through the day as it is, the dose in BSYNC-ON might not be enough to wake you up with the kick it’s supposed to. There’s about the same amount of caffeine in each one of these supplements as there is in an espresso, so if a single espresso wouldn’t usually perk you up, this one may not be for you.

If you’re wondering why they’ve picked these four ingredients specifically, here’s what the benefits are stated to be for each one:

  • Caffeine: improves concentration, performance and alertness
  • Vitamin B12: reduces feelings of fatigue, contributes to energy-yielding metabolism, cognitive functioning and functioning of the nervous system
  • Vitamin B5: reduces feelings of fatigue, supports mental performance and natural functioning of the nervous system
  • Zinc: contributes to healthy cognitive functioning

How is this different from drinking a cup of coffee?

BSYNC On box and brochure

The crucial difference between taking a BSYNC-ON at bedtime and drinking a cup of coffee when you wake up is this: BSYNC-ON is designed to ensure you’re energised and alert from the moment you open your eyes, whereas if you wake up, make a coffee, consume the coffee, etc, the caffeine isn’t energising your system until you’ve been awake for a while.

Plus, BSYNC-ON has got those extra vitamins in it. Is there B12 in your morning coffee? Maybe if you make it with fortified soy milk or something like that, but probably not as much as you’ll get from a peppy little wake up pill.

Does BYSNC-ON really work?

The clinical trials say so, as have wider consumer trials, and my personal experience is that yes, BSYNC-ON tablets really do work. To give you a bit of extra insight into my personal biology and things that could make it more or less effective, I’ve been testing these out while also taking amitriptyline, which is a prescription sleeping tablet designed to make even the most insomnia-ridden human go to sleep within a reasonable time after getting into bed.

I was already *not a morning person* before I started taking amitriptyline, and BOY does that stuff make you extra flippin tired in the mornings. It’s a sleep-through-your-alarm, wake-up-feeling-stoned type of tablet, and I genuinely found that BSYNC-ON cancelled out that grogginess for me and meant that I opened my eyes feeling fresh.

How to help ensure they work well for you

One thing I will say, is that you’ve got to follow a rule that’s mentioned in their brochure about not eating two hours before bed (which you shouldn’t do if you want a good night’s sleep anyway, but that’s besides the point). Why do I say this? Because if you’ve just eaten and then you take your BSYNC supplement, it’s going to release into your system WAY EARLIER than it is supposed to. I found that out when I ate pizza late one night and the supplement woke me up at about 5am instead of 7am. Never again.

It’s also worth noting that I am pretty caffeine sensitive – a regular coffee shop coffee gives me the jitters, and one day when I didn’t eat breakfast after my BSYNC-ON woke me up, I was so buzzed on caffeine I did all my work for the day by lunchtime and had to go lay down because I was too perked up. Days where I ate breakfast, this wasn’t an issue, so if you’re also a caffeine sensitive soul I’d suggest you avoid having an empty stomach for too long after these kick in.

Anything else I should know?

As with any supplement, if you’re taking a prescription medication of some kind you should check with your doctor before you start taking these. Since testing them out, I’m now also on a stimulant ADHD medication and have been advised to avoid caffeine where possible – which sadly means no more BSYNC-ON for me. Pregnant women and children are also advised to be careful with caffeine, so that’s also worth keeping in mind.
