š¤Is Your Supplement Even Working?
What we learned from a major supplement failāand how to avoid it

Hey Friends,
We thought we had our supplement game dialed in. For years, we were taking daily Vitamin D dropsāfeeling pretty proud of ourselves for checking that box.
Then we got tested.
And⦠surprise! Both of our Vitamin D levels were shockingly lowālike, āyou need a shot immediatelyā low. š³
The lesson? Just because youāre taking a supplement doesnāt mean itās working.
Quality matters. Absorption matters. Testing matters.
And sometimes what you think is supporting your body⦠isnāt.
This week, weāre diving into the smarter side of supplementation: how to choose better, how to build real consistency, and how to figure out what your body actually needs (not just whatās trending).
If you caught this weekās Sync Stack you already saw a few products weāre loving and habit shifts weāre making around snacks and supplementation. This newsletter takes the next stepāwith strategy, science, and tools you can use together.
Letās get into it.

Bio-Optimizers: The Smart Way to Supplement
Most couples waste time, money, and mental energy on supplements that donāt deliver. Why? Because up to 70% are under-dosed, unregulated, or simply riding the influencer hype train.
This week, weāre focusing on a smarter approach: choosing one supplement that supports your actual goals and labsānot the latest TikTok trend.
Smart inputs, real outcomes.
š Why It Works
Itās not the number of supplementsāitās the strategy behind them. What you do need is a supplement that aligns with your lifestyle and physiology.
Think:
Magnesium for deeper sleep
Creatine for performance and cognition
Adaptogens for stress and energy regulation
Itās not about moreāitās about targeted support that moves the needle.
š A JAMA review found that 70% of supplements are ineffective or misleading.
But stats donāt tell the whole storyāand weāll explain why.
š¬ A Quick Note From Us
Youāve probably seen a lot of headlines suggesting supplements donāt work. And itās trueāmany donāt. But hereās what those headlines miss:
š You must examine the source, funding, and the actual quality of what is being tested.
In our health journey, supplements have filled critical gapsāwhen used intentionally, with testing, and quality in mind.
For exampleāhereās an actual Amazon ad I got this week. Tempting price, flashy claims... but this is exactly where quality gets overlooked. We all love a good deal, but the old saying still holds: you get what you pay for.

Weāre not here to preach a āpill for everythingā model. Itās about supplementing for deficiencies. However, we are here to say:
When done correctly, targeted supplementation can change everything.
š¤ Do This Together
Step 1: Identify a performance edge.
Where do you want to feel betterāsleep, focus, mood, energy, recovery?
Step 2: Choose one supplement that supports that goal.
Some of our go-toās:
Magnesium glycinate ā sleep, stress, regularity
Creatine monohydrate ā performance, cognition, longevity
Rhodiola or ashwagandha ā cortisol and energy balance
Electrolyte minerals ā hydration, mood, brain clarity

ā”Customizing It to Your Level or Goal
If youāre already supplementing, drop anything that isnāt aligned or trackable.
If youāre just getting started, start small. Pick one supplement. Build it into a routine. Then stick with it.
ā³ It can take as little as 3 to 6 weeks and in most cases up to 90 days, to feel the full effects of a supplementāespecially for vitamins and minerals that work subtly over time. Some people donāt notice a change until they stop taking it and realize what was helping.
So donāt expect overnight results.
Instead, track small shifts in energy, focus, mood, or sleep. Thatās where progress shows up first.

Supplements only work when theyāre used consistently. So letās make it easy.
The Sync Stack Formula:
After I [existing habit], I will [take my supplement].
Examples:
ā After I make my coffee, Iāll take magnesium.
ā Before I brush my teeth at night, Iāll take my sleep stack.
ā After my workout, Iāll take creatine with protein.
Repeat it. Track it. Let it work.
š§ Get Started: Where to Test What You Need
We learned the hard wayāour daily Vitamin D drops werenāt cutting it, and testing was the only thing that revealed the gap.
Here are a few testing options to explore if you're ready to get data-backed about your supplement strategy:
ā Function Health
ā Superpower
ā Lifeforce
ā Thorne (at-home kits)
ā LabCorp (self-order labs)
š No affiliationsājust a starting point for anyone ready to take this step.

š TL;DR |
