How do I choose the right Zervelli® supplement?

Start by identifying the nutritional category you want to add to your routine.

Before purchasing, compare product pages and review:

  • active ingredients;
  • amounts per serving;
  • serving size;
  • dosage form;
  • suggested use;
  • allergen information where applicable;
  • warnings and precautions; and
  • package size or number of servings.

Consider your overall diet and any other supplements you already use so you do not unintentionally duplicate ingredients.

If you are unsure whether a supplement is appropriate for you, especially if you are pregnant or nursing, taking medication or managing a medical condition, consult a qualified healthcare professional.

Where can I find ingredients and Supplement Facts?

Review the individual Zervelli® product page, product packaging and Supplement Facts panel.

Depending on the product, this information may include:

  • serving size;
  • servings per container;
  • nutrient or active-ingredient amounts;
  • Daily Value information where applicable;
  • other ingredients;
  • allergen information;
  • suggested use;
  • warnings; and
  • storage instructions.

The physical label supplied with the product should always be reviewed before use.

Are the glasses, fruit, food or other items shown in product photos included?

Not necessarily.

Zervelli® lifestyle images may include glasses, water bottles, fruit, food, exercise accessories, serving utensils or other props to demonstrate a product in context.

Only the product, quantity and accessories specifically identified on the applicable product page or packaging are included with your purchase.

What if the packaging I receive looks slightly different from the website?

Packaging graphics, label layout, color presentation or other minor non-material details may occasionally change as packaging is updated.

Photography, lighting and display settings may also affect how colors appear online.

The product received should still materially correspond to the product ordered, including its identity and applicable core specifications.

Always review the physical Supplement Facts panel and label before use.

If your order appears materially different, incorrect or incomplete, contact us and include photographs where useful.

How should I take Zervelli® supplements?

Follow the suggested-use directions shown on the applicable product label.

Different Zervelli® products have different serving formats. Examples include:

  • capsules taken with food;
  • softgels taken with a meal;
  • adult gummies chewed as directed;
  • tablets taken at a specified time;
  • powders mixed into water or beverages; and
  • electrolyte stick packs mixed with water.

Do not assume that directions for one Zervelli® product apply to another.

Can I take several Zervelli® supplements together?

Some adults use more than one dietary supplement, but your total daily intake matters.

Compare labels carefully for overlapping ingredients such as:

  • Vitamin D;
  • Vitamin C;
  • zinc;
  • magnesium;
  • other vitamins or minerals; and
  • ingredients that may interact with medications.

If you use medications, have a medical condition or plan to combine several supplements, consult an appropriate healthcare professional.

Are Zervelli® supplements intended to diagnose or treat medical conditions?

No.

Zervelli® dietary supplements are intended to complement a balanced diet and everyday wellness routine.

Unless specifically authorized and lawfully stated, our products are not intended to diagnose, treat, cure or prevent disease.

Product information on Zervelli.com should not be used as a substitute for individualized medical advice.

What should I know before using Vitamin D3 + K2?

Zervelli® Vitamin D3 + K2 combines Vitamin D3 with Vitamin K2 as part of an everyday bone nutrition routine.

If you use warfarin or another anticoagulant medication, consult your healthcare professional before using a Vitamin K-containing supplement.

Also consider Vitamin D supplied by other supplements you may already use.

What should I know before taking Zervelli® Omega-3?

Zervelli® Triple Strength Omega-3 contains fish-derived EPA and DHA.

Review the product label before use if you have a fish allergy.

If you take anticoagulant medication or are preparing for surgery, consult a qualified healthcare professional before use.

What should I know about Zervelli® Magnesium Glycinate?

The Zervelli® Magnesium Glycinate formula is designed to provide a clearly stated amount of elemental magnesium per serving.

When comparing magnesium supplements, remember that the weight of a magnesium compound is not the same as the amount of elemental magnesium.

People with kidney disease or those using medications that may interact with magnesium should consult a healthcare professional.

What should I know about the Probiotic Daily 20B formula?

Zervelli® Probiotic Daily 20B is intended as a once-daily probiotic supplement.

Review the finished product label for the applicable probiotic strains, CFU amount and storage directions.

Probiotic potency can depend on formulation, shelf life and storage.

Individuals who are severely immunocompromised should consult an appropriate healthcare professional before taking probiotic supplements.

How should I use Zervelli® Prebiotic Fiber Blend?

Follow the serving directions on the package.

If you are new to supplemental fiber, a gradual introduction may help you assess your individual tolerance.

Mix the powder with the recommended amount of water and maintain adequate fluid intake.

People with sensitive digestive systems or specific dietary restrictions should consider individual tolerance.

What should I know about Zervelli® Sleep Routine Melatonin?

Zervelli® Sleep Routine Melatonin is an adult supplement designed around a low-dose bedtime routine.

Follow the label directions and do not drive or operate machinery after taking melatonin.

Pregnant or nursing individuals, people using medications or those experiencing persistent sleep difficulties should consult a qualified healthcare professional.

How should Zervelli® powders be prepared?

Preparation varies by product.

  • Collagen Peptides + C may be mixed into water or another suitable beverage.
  • Creatine Monohydrate may be mixed into water or another preferred beverage.
  • Plant Protein Daily may be mixed with water, plant-based milk or used in a shake.
  • Electrolyte Hydration should be mixed with the amount of water shown on the package.

Always use the scoop or individual stick serving according to the applicable product label.

How should I store Zervelli® supplements?

Follow the storage directions shown on each product label.

General examples may include:

  • keeping containers tightly closed;
  • protecting products from excessive moisture;
  • avoiding excessive heat or direct sunlight where instructed;
  • keeping powder scoops clean and dry;
  • storing probiotic products according to package directions; and
  • keeping all supplements out of reach of children.
What should I do if the safety seal or packaging is damaged?

Do not consume a supplement if the tamper-evident seal appears broken before first opening or if the product arrives in a condition that raises concerns about product integrity.

Examples may include:

  • a broken or missing safety seal;
  • a cracked bottle or container;
  • leaking softgels or gummies;
  • torn or punctured powder packaging;
  • moisture intrusion; or
  • other obvious shipping damage.

Does Zervelli® offer subscriptions or recurring orders?

If Zervelli® offers a recurring-purchase or subscription option, the recurring price, billing frequency, delivery schedule, renewal terms and cancellation method will be disclosed before enrollment where required.

Shipping & Delivery

Shipping charges, processing, delivery and tracking
How much does shipping cost?

Standard shipping is free on qualifying orders of US$38 or more.

For qualifying orders below US$38, the standard shipping fee is US$2.99, unless a different rate or restriction is displayed at checkout.

Always review the order summary for the final shipping method and charge.

How long does Zervelli® order processing take?

Orders are generally processed within 1–3 business days after payment confirmation.

Weekends, public holidays, high order volume, inventory transfers, payment review or address verification may affect processing time.

Processing time is separate from delivery time.

How long does delivery take?

Estimated delivery is generally 10–20 business days after dispatch, in addition to order-processing time.

Actual timing may depend on:

  • destination;
  • shipping carrier;
  • customs clearance;
  • public holidays;
  • weather;
  • local delivery networks; and
  • other transportation conditions.

This is an estimate rather than a guaranteed delivery date unless a specific guarantee is expressly provided.

Where does my Zervelli® order ship from?

Orders may be fulfilled from different warehouses or fulfillment facilities depending on inventory, product type, destination and shipping requirements.

Products within the same order may occasionally arrive in separate parcels.

Shipping origin may differ from the operating company's business location.

Can all Zervelli® supplements be shipped internationally?

Not necessarily.

Dietary supplement import rules differ by country and region.

Restrictions may apply to products or ingredients such as:

  • melatonin;
  • probiotics;
  • fish-derived omega-3;
  • collagen or other animal-derived ingredients;
  • powders; or
  • products subject to destination-specific supplement regulations.

Enter your shipping address during checkout to see the available options for your order.

How do I track my order?

When tracking is available, we send a shipping confirmation containing a tracking link or tracking number.

You can check the relevant carrier's official tracking page.

You may also use 17TRACK as an optional independent tracking lookup where the tracking number is supported.

Tracking availability depends on the carrier and shipping method.

Why has my tracking stopped updating?

Tracking may temporarily pause while a parcel moves between carriers, distribution centers, customs facilities or local delivery networks.

Newly created tracking numbers may also take time to display the first carrier scan.

If tracking has not changed for an unusually long period or the estimated delivery window has passed, contact us with your order number and tracking number.

Will I have to pay import duties or customs fees?

International deliveries may be subject to VAT, customs duties, import taxes, brokerage charges or carrier fees.

Charges collected through Zervelli.com will be shown at checkout where applicable.

Other charges may be assessed by local customs authorities or delivery carriers according to applicable law.

What if my package is late, missing or marked delivered but I cannot find it?

First check:

  • your delivery address;
  • parcel locker;
  • front, side or rear delivery areas;
  • household members;
  • building reception; and
  • mailroom where applicable.

If the parcel is still missing, contact us with your order number and tracking information.

We will review the shipment and assist with the appropriate resolution.

What if my Zervelli® order arrives damaged or incomplete?

Contact us as soon as reasonably possible with:

  • your order number;
  • product name;
  • description of the problem; and
  • photographs where useful.

Photographs of the supplement bottle, pouch, stick pack, outer packaging, safety seal and shipping carton may help us assess the issue.

Do not consume a product if the packaging condition creates concerns about product integrity or tampering.

Returns & Refunds

Understand our 30-day return process
What is the Zervelli® return policy?

Our Return & Refund Policy provides a 30-day commercial return window measured from delivery for eligible purchases made directly through Zervelli.com.

Eligibility may depend on product condition, whether a consumable product has been opened, the reason for return and applicable law.

This commercial policy is in addition to mandatory consumer rights that may apply in your location.

Can I return an opened Zervelli® supplement?

Return eligibility may differ for unopened, opened, partially used or consumed dietary supplements.

Because Zervelli® products are ingestible, safety, hygiene and product-integrity considerations may apply once a product has been opened.

Contact customer support before sending an opened product back.

Rights relating to damaged, defective, unsafe or materially misdescribed products remain unaffected.

How do I request a return?

Email service@zervelli.com and include:

  • your name;
  • order number;
  • checkout email;
  • product name; and
  • a brief explanation where relevant.

We will explain the next steps and confirm whether a physical return is required.

Where should I send my return?

Contact customer service first for the authorized return address.

The operating company's address, supplier address, shipping-origin facility or address printed on the outbound parcel is not automatically the correct return warehouse.

Do not send a product anywhere until Zervelli® Customer Care provides or confirms the appropriate return instructions.

Who pays return shipping?

For an eligible return based solely on personal preference or change of mind, the customer generally pays return shipping unless applicable law or our instructions provide otherwise.

If a return is required because of our confirmed error, shipping damage, a defective product or an incorrect product, reasonable return-shipping costs may be covered where appropriate.

When will my refund arrive?

Once an approved refund is issued, it is generally returned to the original payment method used at checkout.

Banks, card issuers or payment providers generally take approximately 5–10 business days to post the refund after it has been issued.

Any shorter deadline required by applicable consumer law takes precedence.

What should I do if I cannot find my refund?

First check the original payment account and contact your bank, card issuer or payment provider regarding the refund posting status.

If the expected posting period has passed, email us with your order number and refund confirmation so we can investigate.
