Our story
A small catalog on purpose
Apexzen was started by a founder who wanted fewer bottles and clearer labels. Every product shows its full Supplement Facts, and when a formula uses a blend, the page says so.

What the research says.
We don't cite studies to look credible. We cite them so you can compare the study dose with the Supplement Facts on each product page.
| Study | Year | Dose | Outcome | Source |
|---|---|---|---|---|
| Ashwagandha root extract for perceived stress | 2012 | 300mg KSM-66 x2/day | Significant reduction in serum cortisol (-28%) and perceived stress scores (PSS) vs placebo in double-blind RCT over 60 days. | PubMed 23439798 |
| Magnesium supplementation and sleep in older adults (magnesium oxide) | 2012 | 500 mg magnesium/day (as magnesium oxide), 8 weeks | Improved sleep efficiency, sleep onset latency and early morning awakening vs placebo in an 8-week RCT (n=46). Tested magnesium oxide, not glycinate: the finding is about magnesium, not this specific form. | PubMed 23853635 |
| Lion's Mane (Hericium erinaceus) and mild cognitive impairment | 2009 | 1000mg x3/day (3g total) | Significant improvement in cognitive function scores at weeks 8, 12, 16 vs placebo. Scores declined after cessation, supporting compound effect. | PubMed 18844328 |
What we get asked the most.
How fast will I feel results?
Two timelines. Compounds like L-Theanine and Magnesium Drift work within 30-60 minutes. Adaptogens like Ashwagandha Apex work on HPA axis modulation and take 4-8 weeks to compound. We tell you upfront which is which on every product page.
Are these FDA-approved?
Dietary supplements are not FDA-approved (that applies to drugs). They are made by our manufacturing partner in FDA-registered facilities that follow cGMP standards. FDA registration covers the facility, not the product: it is not an FDA approval.
Do you use proprietary blends?
Most Apexzen formulas list each ingredient with its own amount. Four do not: Tongkat Apex (a 745 mg blend of 13 botanicals), Greens Apex Foundation (4 blends with total weights), Max Detox (one 1,532 mg blend) and Calm Drops Apex (a 50 mg mushroom complex). On those labels every ingredient is still named and the blend weight is shown, but not the amount of each ingredient inside the blend. Each product page says which kind of label you are buying.
Will this interact with my prescription medication?
Some compounds (5-HTP, Ashwagandha, magnesium, omega-3) can interact with SSRIs, blood thinners, blood pressure medication, thyroid medication, and sedatives. Each product page lists known interactions. If you take prescription medication, talk to your physician before starting any protocol.
Can I take more than one supplement at the same time?
Yes. The bundles are designed to stack. We sequence the PM stack (Magnesium + Ashwagandha) at night and the AM stack (B-Complex + Omega-3) at breakfast. Each bundle page shows the timing protocol.
What if it doesn't work for me?
