Why your AI can't check your supplements and build a protocol

Paste your supplement list into an AI and it will flag a famous pair or two, then lose track. Rala reads every label, checks every combination against your meds, and remembers it all next time.

Read the full comparison

It doesn't read the labels

AI

It guesses what's in a product from its name, so it misses the zinc hiding in your multivitamin and your immune blend.

RAL

Every product is read from its label, ingredient by ingredient with the amounts, so a duplicate shows up whatever the bottle calls it.

It checks a pair, not a stack

AI

Ask about two supplements and it answers. Twelve bottles make sixty-six pairs, and it won't check them all.

RAL

Every combination in your stack is checked, and against your meds too, every time you add or remove something.

It can't add up the totals

AI

It doesn't know that three of your bottles each carry magnesium, or that together they pass the safe upper limit.

RAL

The nutrition panel totals every nutrient across your supplements and your food, and flags anything over its safe limit.

It forgets your stack

AI

Start a new chat and it has forgotten every bottle you listed last week.

RAL

Your stack lives in your health profile, so every check, every answer and your protocol start from what you actually take.

The methodology

How we check every product in your stack: three sources, five evidence tiers.

Rala grades every product at the ingredient level, so a brand name never substitutes for proof.

01

Human studies

Published clinical research on the ingredient. Animal and cell studies are noted, never counted as proof.

02

Real reviews

Thousands of consumer reviews per product. Top tier needs 66%+ positive, and what buyers report has to match the studies.

03

Biohacker evidence

Ten well-known biohackers, read in full. One vote each, scored separately so it never masquerades as a study.

How it works

From a cabinet of bottles to one daily protocol in three steps

01

Scan your labels and fill in your profile

Photograph each label or type the names, then add your goals, meds, diet, exercise and sleep. Blood work is optional; add it if you have it.

02

See what clashes, doubles up and works

Rala checks every combination, finds what you're taking twice, and grades each product on the human studies. You approve or reject every suggested change.

03

Get your comprehensive protocol

What to take and when, what to keep apart and what to drop, plus diet and exercise suggestions, rebuilt whenever your stack changes.

Inside the checker

Six parts that turn a pile of bottles into a protocol.

Your profile, the research, the recommendations, your daily protocol, the nutrition panel and Rala all start from the bottles you already own.

01 Every bottle you take

Every bottle you take, in one place.

Scan the labels or type the names and each product is filed ingredient by ingredient with its amounts, beside your meds, goals, diet, exercise and sleep. Blood work is optional. Add or remove a bottle and everything is checked again.

Sample Health Profile

The health profile: nine sections, body basics, goals, sleep, diet, exercise, supplements and medications, additional information, test results and wearable, each with how complete it is

02 Each product, graded

Find out which bottles are worth the money.

Pick any product in your cabinet and the research engine reads the human studies on its ingredients, the reviews of the product itself and what ten well-known biohackers say, then grades it on five tiers with its cost per month. Keep what earns its place.

See how research works

03 Better options

When a better option exists, you see it.

If a product in your stack has thin evidence or doubles up, Rala suggests graded alternatives for your goals, checked against your meds and allergies, with the tier, the review split and the monthly cost. You decide.

04 What to take, and when

What to take, when, and what to keep apart.

Every supplement sits in a timing block around your own day, with the reason it's there. Around the schedule, the protocol shows the synergies to keep, the conflicts to space apart, the duplicates to cut and the products doing two jobs, plus a fasting window and diet and exercise suggestions. Change a bottle and the whole protocol rebuilds.

Sample Supplement Schedule

The supplement schedule: time blocks around the member's own day, each product with its dose

Sample Daily Protocol

The rest of the Daily Protocol page, sections 2 to 6: protocol details covering timing, fasting, synergies, conflicts, redundancies and efficiencies; diet and exercise suggestions; supplements suggested from the whole health profile; the wearable; and the nutrition and supplements panel

05 Overlaps and limits

See when your stack goes over a safe limit.

The panel adds up every nutrient across all your supplements and your food, line by line against your targets and safe upper limits, so three bottles of the same mineral can't hide. Add blood work if you have it and it sits beside the totals.

Learn about nutrition analysis
The nutrition panel with blood work (Robert, 17 Oct 2026): each vitamin and mineral from food and from supplements, the total, the target and how the member is doing, beside the uploaded blood test, each marker marked low or in range

06 Ask Rala about your stack

Rala, your personal longevity assistant

Ask whether two of your supplements can go together, why something is in your protocol, or whether a new bottle is worth adding. Rala answers from your stack, your meds and the evidence, and never invents a source.

Deep research engine

Reads the studies, the reviews and the biohacker views on any product before you buy it.

Chat anytime

Knows every bottle in your stack, so the answer fits what you actually take.

Reverse Age Lab Assistant (Rala)

Rala has all the information from your Health Profile, Supplements & Protocol. Feel free to ask any health, wellness, diet or exercise questions.

I take Doctor's Best magnesium and Triple Calm Magnesium. Do I need both?

Here is what your two labels show:

1. They double up

Both are magnesium. Two tablets of Doctor's Best give 200 mg and two capsules of Triple Calm give 150 mg: 350 mg a day from supplements, right at the upper limit for adults. A multivitamin with magnesium would take you over it.

2. Keep one

Either one fits your sleep goal on its own. Doctor's Best costs $10.50 a month and Triple Calm $29.99.

3. Your meds

Magnesium can get in the way of some meds taken at the same time, so the one you keep goes at bedtime, hours away from your morning meds.

4. Savings

Dropping one saves you up to $29.99 a month.

Tell me which one to keep and I'll update your profile.
