Frequently asked questions
What is SYNC?

SYNC is a premium, AI-powered supplement system that delivers daily vitamin packs designed for your body, your data, and your goals. Backed by science, powered by personalization—this is next-gen wellness.
How does the SmartStack™ quiz work?

Our quiz maps your health goals, lifestyle, symptoms, and—if you choose—wearable device data. Then our AI engine uses clinical research and nutrient synergy models to build your ideal formula.
Do I need a wearable device to use SYNC?

Not at all. You can use SYNC with the quiz alone, but connecting a device like Apple Watch, Oura, or WHOOP enhances accuracy and precision.
Can I retake the quiz or update my data?

Yes. We recommend re-taking the quiz or resyncing your device whenever your goals or lifestyle change. Your pack will update accordingly.
Is my health data safe?

Yes. All personal health data is encrypted, stored securely, and never sold. We follow industry-standard best practices aligned with HIPAA-level safeguards.
How is my health data used?

Only to serve you better. Your data is used to generate your personalized recommendations and, if you opt-in, to improve our AI’s accuracy.
How does SYNC use AI?

Our SmartStack™ algorithm cross-analyzes your responses with clinical research, dosing levels, nutrient synergy, and wearable data to deliver a dynamic formula.
Who can use SYNC?

SYNC is for adults seeking proactive health support. If pregnant, breastfeeding, or on medication, consult your provider first.

When will I start to feel a difference?

Some feel better in 1–2 weeks; for most, 4–6 weeks of consistent use delivers benefits. These are long-term wellness upgrades.
Why should I choose SYNC over other supplement brands?

Most brands use one-size-fits-all formulas. SYNC builds yours from scratch, backed by clinical science and AI personalization.
How personalized is SYNC really?

Every formula is custom-built using your quiz answers and/or wearable data. No templates—only your optimized formulation.
What if I don’t want to take the quiz?

No problem. You can choose from expert-curated Solution Packs targeting energy, sleep, focus, gut health, and more.
What makes SYNC different from AG1, Care/Of, or others?

SYNC combines AI, wearable data, and clinical-grade ingredients—resulting in highly customized, science-backed supplements.
Is SYNC compliant with FDA regulations?

Yes. Our products are made in FDA-registered, UL cGMP-certified facilities and tested by ISO-accredited labs.
What technology does SYNC use?

SYNC uses InspectRx visual verification, wearable integrations, and a proprietary AI engine for personalization and QA.

Orders & Delivery
Where do you ship to?

Our goal is for every customer to be totally satisfied with their purchase. If this isn’t the case, let us know and we’ll do our best to work with you to make it right.

How long does shipping take?

Your first pack usually arrives 3–5 business days after your order is processed. You’ll receive tracking updates along the way.
Is SYNC a subscription?

SYNC gives you options. Subscribe for monthly deliveries (with full flexibility to pause, skip, or cancel anytime), or make a one-time purchase.
Can I pause, cancel, or skip my subscription?

Yes—easily. You can pause, cancel, or skip shipments directly from your account.
Will I be reminded before my next order?

Absolutely. We send reminders before every renewal so you can adjust your formula, skip a shipment, or update your details.
What if I don’t like it or want to stop?

You’re always in control. While we don’t offer money-back guarantees, we’ll work with you to adjust your formula or pause future orders.
What if my order is damaged or delayed?

If your order arrives damaged or is delayed, just email hello@beinsync.co and we’ll make it right.
Do you offer refunds or returns?

Because each SYNC pack is custom-built, we can’t accept returns. But we’ll help you adjust your formulation and support your goals.
Why don’t you offer a money-back guarantee?

Each pack is made just for you and can’t be reused or resold. That said, we’ll always support you in making the right adjustments.

Diet & Medical
Are SYNC supplements safe with medication?

We always recommend consulting your doctor before adding supplements if you're on prescription medication or managing any health condition.
Can I take SYNC while pregnant or breastfeeding?

Please consult your healthcare provider. We can personalize formulations for different life stages, but guidance from your doctor is essential.
Are your products vegan, gluten-free, or allergen-friendly?

Most of our ingredients are vegan, gluten-free, soy-free, and non-GMO. We screen for common allergens and let you exclude any during the quiz.
What if I have food allergies or intolerances?

You’ll be able to list any allergies during the SmartStack™ quiz, and we’ll exclude any ingredients that don’t suit you.
Do you work with healthcare professionals?

Yes. SYNC protocols are developed alongside functional medicine experts, nutrition scientists, and clinical practitioners.
I eat healthy already—do I need supplements?

Even the best diets can leave gaps. SYNC helps optimize your nutrition, accounting for soil depletion, stress, and individual absorption issues.
How do I know the ingredients are safe for me?

We use a multi-layered screening process based on your responses. Supplements are tested for purity and potency. Adjustments can be made anytime.
What if I have a health condition or take medication?

SYNC is not a replacement for medical care. We recommend consulting your provider. The quiz allows you to flag conditions and medications for tailored support.

Nutritional & Ingredients
What’s in my SYNC pack?

A tailored stack of vitamins, minerals, adaptogens, and botanicals—chosen specifically for your profile. You’ll get a clear breakdown of what’s in your pack, why it was chosen, and how it supports your body.
Where do your ingredients come from?

We source from trusted, GMP-certified suppliers who meet rigorous standards for purity and quality. Many are certified organic, Fair Trade, or Kosher/Halal where applicable.
Are your vitamins synthetic or natural?

It depends on what your body needs. We prioritize bioavailable forms—natural when possible, scientifically advanced when better absorbed. Everything is clean, tested, and effective.
Are your ingredients bioavailable?

Yes. We only use highly absorbable forms—like methylated B vitamins and chelated minerals—so your body actually uses what it’s given.
What’s the shelf life of your supplements?

Each supplement is stamped with a use-by date based on rigorous stability testing. Most have a shelf life of 12–24 months, depending on the ingredient.
How do I know which nutrients I actually need?

That’s the magic of SYNC. Our AI analyzes your quiz inputs and wearable data to identify gaps, imbalances, and optimization opportunities. You only get what your body benefits from.
How are your supplements tested for quality?

Every batch is tested for purity, potency, identity, and contaminants. Our partner follows FDA cGMP and third-party quality protocols including random lot testing and full traceability.
What types of supplements does SYNC offer?

SYNC offers over 60 bioavailable supplements including vitamins, minerals, herbs, mushrooms, and amino acids—each backed by clinical evidence and rigorously tested for purity, potency, and absorption.
Does SYNC use eco-friendly packaging?

Yes. Our packaging uses 80% less plastic than traditional pill bottles and includes recyclable materials and eco-friendly tape. SYNC also ships carbon-neutral and is actively developing compostable pack options.
