Livestack evidence summary — education, not medical advice.

The intelligent way to stack.
Livestack is an evidence-first advisor for building a personal
supplement stack. Answer a short intake and get a specific list: what is
worth taking for your situation, at what dose, at what daily cost — and
what we left out on purpose, with the reason for each.
Every visible number traces to a graded evidence record. Where the
evidence is weak, we say so.
Every ingredient–goal pairing carries a letter grade, from A (multiple human RCTs) to D (animal or in-vitro only). Grade D never appears in a recommendation.
What was left out
Each stack ends with exclusions and the reason — interactions, thin evidence, budget. The absences are part of the result.
A commission wall
The engine that picks ingredients cannot see prices, merchants, or commission rates. That split is enforced in the codebase, not just promised.
A sample stack
Built from our evidence tables for one fixed example: sleep and
strength, no medications, standard effort. Your intake produces your own
version — including the exclusions that apply to you.
Melatonin is the hormone your brain releases as light fades, signaling circadian night. Taken 30–60 minutes before bed, it supports falling asleep sooner and helps shift sleep timing after travel or schedule changes.
0.5–1 mg, 30–60 minutes before bed; raise only if a week at the low dose does nothing
Cautions
Late-day caffeine works directly against evening melatonin signaling. Keep caffeine before early afternoon if sleep timing is the goal.
Magnesium is a cofactor in over 300 enzyme systems, including those governing muscle contraction, nerve signaling, and sleep-related GABA activity. Supplementation supports normal muscle relaxation and sleep quality, mainly in people whose dietary intake runs low.
200–400 mg elemental in the evening; most useful when dietary intake runs low
Ashwagandha root extract appears to moderate the stress response, with trials showing lower perceived stress and modestly lower cortisol over 6–12 weeks. It may also support sleep quality in people whose sleep runs short under stress.
300–600 mg root extract in the evening; sleep effect rides on the stress effect
Glycine is an amino acid that acts as an inhibitory neurotransmitter and lowers core body temperature slightly when taken before bed — a signal associated with sleep onset. Small trials show better subjective sleep quality and next-day alertness at 3 g.
3 g powder 30–60 minutes before bed; evidence is small-trial only
L-theanine, an amino acid from tea, crosses into the brain and increases alpha-band activity associated with relaxed alertness. Paired with caffeine it supports attention while smoothing caffeine’s edge; alone it supports calm without sedation.
200 mg in the evening; calm-without-sedation profile, weak direct sleep data
Creatine raises phosphocreatine stores in muscle, supporting rapid ATP regeneration during short, hard efforts. Over weeks of training this supports gains in strength, power, and lean mass, with smaller effects on cognitive tasks under sleep loss.
Goals, basics, current supplements, medications, constraints. About
three minutes, no account, and answers stay on this device unless
you choose to save.

Each ingredient carries its evidence grade, dose with units, timing,
and daily cost. Below the stack: what was left out and why —
interactions, thin evidence, budget. The notes we store are also on
the interactions page.
Take it to your doctor
This is education, not medical advice. Bring the stack to your
doctor or pharmacist, especially if you take prescription
medication.
Come back without an account
The full stack is yours before any email ask. Share or save from the result to get a link you can bookmark or send. On this browser, stacks you saved also appear under Your recent stacks — no password.
The sample stack is one walk through the tables. You can also start
from an ingredient, a goal, or a study record — and come back when you
want to read further.
How to read a grade, and the compounds we cover only as editorial.
Commissions never influence what the advisor recommends. The engine that
builds your stack cannot read prices, merchants, or commission rates —
here is how that is enforced.
