Most supplement advice is a category guess. Yours is a profile.

Inside every plan

Evidence-graded

Every recommendation ties back to peer-reviewed trials. You see the evidence tier and the PubMed sources behind each supplement, so you can trust the plan and read the primary literature yourself.

Safety-screened

Your medications and conditions are cross-checked against every candidate supplement before a plan is written. Known interactions and contraindications surface as explicit flags. Nothing risky slips through.

Written for you

At least one supplement for every goal you choose, at the exact form, dose, and timing your physiology needs. The plan is not a template with your name at the top. It is written from the profile you shared.

Written and reviewed by clinicians
BSN RN PhD MD PharmD

Protocols authored by nurses and PhD researchers. Fact-checked by physicians and pharmacists. Every claim traces back to peer-reviewed evidence in PubMed.

How it works

Three steps, then a plan written for you.

Nourish is built around the same evidence base your doctor reads. Our protocols are written by BSN, RN, and PhD researchers and fact-checked by MDs and PharmDs. The diagnostic pulls the signals that matter, your profile is matched against those vetted protocols, and the plan is written for your physiology, not a category.

01

Share your profile

Age, body, sleep, diet, medications, supplements you already take, conditions, and the goals you care about. The details that determine what your body actually needs and what could interact with what you're already taking.

9 questions, about 3 minutes
02

Your profile is matched to vetted protocols

A matcher pulls the supplement protocols that fit your goals, conditions, and demographic. Each protocol is screened against your medications for known drug interactions, and against your conditions for contraindications. Our clinical reasoning engine then writes the plan from the matched menu and surfaces the safety flags it found.

Evidence-graded, safety-screened
03

Get a specific plan, with sources

At least one supplement for every goal you choose, with exact forms, doses, timing, evidence grade, safety flags, and PubMed citations per supplement. Plus per-goal lifestyle habits to help each recommendation actually work.

Written for you
Methodology

How we read you.

Every question you answer becomes a signal in our matcher. Below is what each signal does, and why we ask.

Sleep hours and quality

What your sleep tells us

Less than 5 hours
More than 9 hours

If you're in the lower band we surface a sleep protocol. The specific combo (general core, anxiety-adjacent, or circadian/shift work) depends on how you rate your sleep quality and what you mention in the free-text.

Daily activity

How active you are

Sedentary
Athletic

Lower activity raises the priority of vitamin D and bone protocols. Higher activity opens muscle, performance, and protein targeting, and tightens the recovery and inflammation track.

Sun exposure

How much daylight you get

Almost none
Most days

Sub-15-minutes-a-day is the single strongest signal for likely vitamin D deficiency, so this is a key input to whether vitamin D belongs in your plan and at what dose.

Diet and restrictions

What and how you eat

Vegetarian Vegan Pescatarian Mediterranean Skipped meals Ultra-processed

Vegetarian or vegan triggers a dedicated nutrient-gap protocol (iron, B12, omega-3 DHA, vitamin D). Eating-habit signals shape fiber, protein, and blood-sugar recommendations.

Medications

What you already take

SSRIs Warfarin Levothyroxine Metformin PPIs Statins

Every protocol carries a drug-interaction table. Your meds are checked against each candidate supplement before any recommendation is written, and the relevant warnings are surfaced on the cards themselves.

Conditions

What your body is navigating

Anxiety Pregnancy Hypothyroidism Type 2 diabetes PCOS Anemia

Used as both inclusion and exclusion signals. Anxiety opens an anxiety-stress protocol; pregnancy excludes ashwagandha and rhodiola; diabetes opens blood-sugar protocols but flags anything that could cause hypoglycemia in combination with your meds.

Goals

What you're after

Sleep quality Energy and fatigue Anxiety and stress Heart health Hormone balance Longevity and healthy aging

Every goal you choose is weighted equally. Each one is matched to its own protocols and gets at least one supplement in your plan.

Free-text notes

What you say in your own words

"I'm running on fumes most days, brain won't shut off at night."

Anything you write is matched against keyword signals on each protocol. "Burnout" lights up the stress-fatigue track. "Caffeine" raises caffeine-related cautions. "Long covid fatigue" surfaces a dedicated CFS adjunct. Specific words change which protocols rise to the top.

References

Every supplement, tied to its evidence.

Below are the directly-cited studies behind each supplement we may recommend. To get to this list we triangulated and read thousands of additional papers that helped us identify drug interactions, clarify dosing, and rule out supplements that don't belong in a plan. Open any supplement to see its sources.

Every link points to the original study in PubMed, the U.S. National Library of Medicine's public research database.

Privacy Policy.

Effective date: June 14, 2026 · Last updated: June 14, 2026

Who we are

Try Nourish (operating as "Nourish") provides a personalized supplement recommendation service at trynourish.co. Throughout this policy, "we," "us," and "Nourish" refer to Try Nourish. This policy explains what information we collect from you, how we use it, and the choices you have.

Information you give us

To generate a personalized supplement plan, our diagnostic asks for:

  • Identifying information: your first name and email address (collected on the loading screen before your plan is shown).
  • Health and lifestyle information: your age, sex, height, weight, activity level, sleep hours and quality, sun exposure, dietary pattern and restrictions, current medications, supplements you already take, health conditions, and the goals you're working toward.
  • Free-text notes: anything else you choose to type into the optional fields in the questionnaire.

How we use your information

  • To generate your personalized supplement plan and surface relevant safety flags (drug interactions, contraindications).
  • To email you a copy of your plan when that feature is available.
  • To improve the protocols and matching logic over time, working with aggregated and de-identified data.
  • To respond to questions or requests you send us.
  • To detect, prevent, and address fraud, abuse, or technical issues.

How we share your information

We do not sell your personal information. We share it only with service providers that help us operate Nourish, under contracts that limit how they may use your data:

  • Anthropic processes your profile and goals through their API to generate the written explanation of your plan. Per Anthropic's commercial terms, API requests are not used to train their models.
  • Supabase hosts the database where we store your profile, your email, and your generated plan.
  • Railway hosts the website itself.

We may also disclose information if required by law, to enforce our Terms of Service, or to protect the rights and safety of users.

How long we keep your information

We keep your submitted profile and email as long as our service operates them, so we can improve the recommendation engine and stay in touch about your plan. If you email [email protected] requesting deletion, we will remove your profile and email from our systems within 30 days, except where retention is required by law (e.g., financial records of any purchases). Aggregated, de-identified data may be retained for analytics.

Your rights

You may request to access, correct, or delete the personal information we hold about you by emailing [email protected]. California residents have additional rights under the California Consumer Privacy Act (CCPA), including the right to know what personal information we collect, the right to delete it, and the right not to be discriminated against for exercising those rights. EU/UK residents have rights under the GDPR / UK GDPR including access, rectification, erasure, restriction, portability, and objection.

Children

Nourish is intended for adults age 18 and over. We do not knowingly collect information from anyone under 18. If we learn we have collected information from a child, we will delete it.

Cookies

We use a small number of cookies and similar technologies for the site to function (e.g., remembering your session during the questionnaire). We do not currently use third-party advertising cookies. If we add analytics or advertising cookies in the future, we will update this policy and, where required by law, ask for your consent.

International users

Our service providers are located primarily in the United States. By using Nourish, you understand that your information may be transferred to and stored in the United States.

Changes to this policy

We may update this policy from time to time. When we do, we will revise the "Last updated" date at the top of this page. Material changes will be highlighted.

Terms of Service.

Effective date: June 14, 2026 · Last updated: June 14, 2026

These Terms of Service ("Terms") are a binding agreement between you and Try Nourish ("Nourish," "we," "us"). By using the Nourish website or service, you agree to these Terms. If you do not agree, do not use the service.

What Nourish is

Nourish is a personalized supplement-recommendation service. After you complete a clinical questionnaire, our matching engine produces a plan covering every goal you select, along with dosing, timing, evidence grade, drug-interaction flags, and citations per supplement. Recommendations are drawn from a vetted protocol matrix derived from independent evidence sources.

This is not medical advice

Nourish is an educational and informational service, not a medical service. Our recommendations do not constitute medical advice, diagnosis, treatment, or a substitute for the care of a qualified healthcare professional. Always consult your doctor, pharmacist, or other licensed healthcare provider:

  • Before starting any new supplement, particularly if you have a medical condition, are pregnant or nursing, or take prescription medications.
  • If you experience any adverse reaction.
  • Before stopping any prescribed medication.

We make every effort to flag known drug interactions and contraindications, but the safety information we surface is not exhaustive and is not a substitute for professional clinical judgment.

Eligibility

You must be at least 18 years old to use Nourish. By using the service you represent that you are 18 or older.

Your account and the email you provide

To see your plan you provide your name and email address. You agree to provide accurate information and to keep it up to date. We will use your email to deliver your plan and to communicate occasionally about Nourish; you may unsubscribe from non-essential emails at any time.

Acceptable use

You agree not to: misuse the service, attempt to gain unauthorized access, interfere with its operation, reverse-engineer or scrape it, submit deliberately false information that may produce unsafe recommendations, or use the service to develop a competing product.

Affiliate links

Some links on this site are affiliate links. When you click a "Where to buy" button and purchase a product, we may earn a commission from the seller at no extra cost to you. Affiliate revenue does not influence which supplement we recommend (that decision is determined entirely by our clinical matcher) nor which brand we recommend (chosen on independent third-party testing). See the Affiliate Disclosure for the full statement.

Intellectual property

All content on the Nourish site, including the protocol matrix, written explanations, design, code, and marks, is owned by Try Nourish or its licensors and is protected by intellectual-property laws. You may use the service for your personal, non-commercial purposes only.

Disclaimers

The service is provided "as is" and "as available," without warranties of any kind, whether express or implied, including (without limitation) the implied warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the service will be uninterrupted, error-free, or that the recommendations will produce any particular health outcome.

Limitation of liability

To the maximum extent permitted by law, Try Nourish and its officers, employees, and agents will not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits or revenues, arising out of or in connection with your use of the service. Our total liability for any claim arising out of or in connection with these Terms or the service will not exceed one hundred U.S. dollars ($100).

Indemnification

You agree to indemnify and hold harmless Try Nourish from any claims, liabilities, damages, losses, and expenses arising out of your misuse of the service or violation of these Terms.

Changes to the service or these Terms

We may modify the service or these Terms at any time. If we make material changes to the Terms, we will revise the "Last updated" date and, where appropriate, notify you by email or on the site. Continued use after changes take effect constitutes acceptance.

Governing law

These Terms are governed by the laws of the State of California, United States, without regard to its conflict-of-laws principles. Any dispute arising out of these Terms or the service will be brought exclusively in the state or federal courts located in San Francisco County, California, and you consent to personal jurisdiction there.

Affiliate Disclosure.

Effective date: June 14, 2026 · Last updated: June 14, 2026

Try Nourish participates in affiliate programs operated by retailers and supplement brands, including (but not limited to) Amazon Associates, BulkSupplements, Thorne, Nordic Naturals, Life Extension, NOW Foods, Sports Research, Garden of Life, Carlson, Heliocare, and others. When you click a "Where to buy" link on our site and complete a purchase, we may earn a commission from the seller. The price you pay is the same whether you go through our link or directly.

What our commission does not change

  • Which supplement we recommend for you. That decision is determined entirely by our clinical matcher, which matches your profile against vetted, evidence-graded protocols. Affiliate relationships have zero input.
  • Which brand we recommend within a supplement category. Brands are chosen based on independent third-party testing (primarily ConsumerLab.com) and well-established trust signals (USP Verified, NSF Certified for Sport, transparent certificates of analysis). We point to the brand we'd buy ourselves.

What it does change

Affiliate commissions are how we fund the work: building and maintaining the protocol library, running the matching engine, paying for the third-party tools and infrastructure behind the recommendations, and continuing to expand and update the evidence base. Without affiliate revenue, this service would either need to charge a subscription fee or shut down.

When we don't link to a product

For some recommendations we deliberately omit a buy link, including:

  • Iron, which should not be taken without confirmed deficiency on bloodwork.
  • Any supplement with a hard contraindication for your profile (e.g., ashwagandha during pregnancy).
  • Supplements with strong safety warnings that warrant a clinician conversation first.
  • Foods (coffee, olive oil, honey) that are everyday grocery items.

FTC compliance

This disclosure is provided in accordance with the U.S. Federal Trade Commission's 16 CFR § 255 ("Guides Concerning the Use of Endorsements and Testimonials in Advertising"). Every page on this site that contains affiliate links displays an in-line affiliate notice.

Questions about how this works: [email protected].

About you

Let's start with the basics.

A few core facts about your body. These shape what you actually need.

Height & weight
Why these questions
Age, sex, height, and weight determine baseline needs for nutrients like iron, calcium, vitamin D, and protein. We use them as inputs to the plan, not as judgments.
About you

How are you sleeping and moving?

Sleep and activity shape almost everything else. Pick the closest match.

Hours per night
Sleep quality
Activity level
Why these questions
Poor sleep and high training loads change which nutrients your body burns through fastest. Magnesium, B-vitamins, and adaptogens come into focus when either is off.
About you

How much do you eat and how much sun do you get?

Rough estimates are fine. We use this to figure out what your diet alone can and cannot cover.

Daily calorie intake
Daily sun exposure
Why these questions
Low calorie intake makes nutrient deficits more likely. Low sun exposure is the strongest reason most people need to supplement vitamin D.
Nutrition

How would you describe your eating?

Pick the one that's closest to your reality. Then tell us more; it makes the plan more specific to you.

Why this question
Your eating pattern tells us which nutrients are at risk and which supplements are even worth taking. The details make the plan specific.
Nutrition

Anything you don't eat?

Restrictions change which forms we recommend and which nutrients you may be short on.

Medications, supplements, conditions

Medications you take.

Tap any you take. We check for interactions and adjust the plan around what you're already on.

Why this question
Many common medications deplete specific nutrients, and some supplements can interact with prescription drugs. This is the safety layer.
Medications, supplements, conditions

Supplements you already take.

We won't recommend anything you already have covered. If the dose is off, we'll say so.

Medications, supplements, conditions

Any health conditions?

Pick anything that applies. This is the most important step for safety and accuracy.

Goals

What do you most want to improve?

Pick any number. The marked ones are matched to what you shared.

Building your plan

Making sense of you.
