Higher-Strength Urinary Acidifier Tablets for Dogs and Cats

Product Description

DL Methionine 500mg Tablets are a higher-strength veterinary urinary acidifier supplement manufactured by Vet Brands International for dogs and cats. Each tablet delivers 500mg of DL-Methionine, an essential sulfur-containing amino acid that, when metabolized, releases sulfuric acid into the urine to lower urinary pH. This helps prevent and manage struvite bladder stones and crystals, supports normal urinary function, and reduces urine odor. The 1,000-tablet pack is suited for extended, vet-directed urinary health management programs.

Benefits

Urine Acidification: Helps lower urinary pH and maintain it consistently below 6.6 under veterinary guidance.
Struvite Stone Prevention: Aids in preventing and managing struvite bladder stones and crystals in dogs and cats.
Normal Urinary Function: Supports overall normal urinary tract function as a veterinary-recommended supplement.
Odor Reduction: Helps reduce urine odor as a secondary benefit of the urine acidification process.
Higher-Strength Formula: Each 500mg tablet delivers a more concentrated dose, allowing for fewer tablets per administration for larger pets.

Frequently Asked Questions

Q1: What is the primary use of DL-Methionine 500mg in pets?

Ans: It is a veterinary urinary acidifier supplement used in dogs and cats to help lower urine pH. It supports the prevention and management of struvite bladder stones and crystals that form when urine becomes too alkaline.

Q2: How does the 500mg strength differ from the 200mg version?

Ans: The 500mg tablet delivers a higher dose of DL-Methionine per tablet, which may be more convenient for larger dogs and cats as it requires fewer tablets per administration while achieving the same urinary acidification goal.

Q3: What is the recommended dosage for cats and dogs?

Ans: For adult cats, the suggested dose is 1 tablet per 10 lb (4.5 kg) body weight, once or twice daily with food. For dogs, the suggested dose is 1/2 tablet per 10 lb (4.5 kg) body weight, once or twice daily with food.

Q4: Can DL-Methionine 500mg be given to kittens?

Ans: No, it should not be administered to kittens. Research has confirmed that excess methionine in kittens can cause toxicity and stunted growth, making it unsafe for use in very young cats.

Q5: How long does it take to see results in dogs?

Ans: When used alongside a vet-prescribed therapeutic urinary diet and treatment for any underlying infection, it can take several weeks for struvite stones to dissolve. The timeline depends on stone size, number, and resolution of the underlying cause.

Q6: Should this supplement be given with food?

Ans: Yes, it should always be administered with food to reduce the risk of gastrointestinal side effects. Giving it with food may also improve its overall efficacy, according to veterinary guidance.

Q7: What conditions make this supplement unsafe to use?

Ans: It should not be used in animals with severe liver damage, kidney damage, pancreatic disease, or acidosis. Always discuss your pet's full health history and current medications with your veterinarian before starting this supplement.

Q8: What are the signs of an overdose?

Ans: Overdose symptoms may include anorexia, uncoordinated muscle movement, and cyanosis, which is a blue or purple discoloration of the skin caused by low oxygen levels. Contact your veterinarian or an animal poison control center immediately if an overdose is suspected.

Q9: How should this product be stored?

Ans: Keep the container tightly closed in a cool, dry place at a controlled room temperature of 15 to 30 degrees C (59 to 86 degrees F). Store away from moisture and light, and keep out of reach of children and other pets.

Q10: Can this supplement be used alongside other pet medications?

Ans: Combining it with certain medications can pose health risks to your pet. It is essential to inform your veterinarian about all medications and supplements currently being given to your pet before starting this product.

This Shipping Policy explains how orders are processed, shipped, tracked, and delivered.

1. Shipping Origin and Fulfillment

Orders are dispatched from our U.S.-based fulfillment center. We deliver to eligible addresses within the United States and to eligible international destinations shown at checkout.

If a destination, shipping service, or product is not eligible for delivery, checkout will not offer that shipping option.

2. Order Processing Time

Orders are generally processed within 1–5 business days before shipment. Processing time is separate from carrier transit time.

Our order cut-off time is 6:00 PM Pacific Time (PT). Orders placed after the cut-off time, on weekends, or on applicable holidays begin processing on the next business day.

Processing may include order verification and preparation for shipment.

3. U.S. Shipping Methods, Costs, and Transit Times

For eligible U.S. addresses, our current shipping options are:

Priority Shipping: $5.99 — estimated carrier transit time of 1–2 business days after shipment.
Standard Shipping: $2.99 — estimated carrier transit time of 3–6 business days after shipment.
Free Shipping: $0 — estimated carrier transit time of 5–8 business days after shipment.

Total estimated delivery time includes both the 1–5 business day processing period and the applicable carrier transit time. The shipping service, cost, and delivery estimate available for your order are shown at checkout before payment.

4. International Shipping

We ship to eligible international destinations. Available international shipping services, shipping charges, and estimated delivery times vary by destination and are displayed at checkout.

For eligible international orders, applicable import duties and taxes are calculated and collected at checkout where required. When these charges apply, the order is shipped on a duties-and-taxes-paid basis so that the same import charges should not be collected again at delivery.

International delivery estimates may be affected by carrier operations, customs processing, local holidays, weather, or other events outside normal transit conditions.

5. Tracking

When tracking is available, you will receive shipment confirmation with tracking information after the order has shipped. Please allow up to 48 hours for tracking information to become active after the carrier receives the shipment.

6. Address Accuracy and Changes

Please review your shipping address carefully before submitting an order. If you notice an address error, contact us as soon as possible. We will try to help before shipment, but an address change cannot be guaranteed once fulfillment or carrier processing has begun.

Additional carrier or re-delivery charges resulting from an incorrect or incomplete address may be the customer's responsibility where permitted by law.

7. Delayed or Lost Shipments

If your shipment has not arrived within the estimated delivery timeframe, please contact us. We will review the tracking information, work with the carrier when necessary, and assist with an appropriate resolution based on the circumstances.

Delivery estimates are not guarantees and may be affected by carrier delays, weather, public holidays, customs processing, or other transportation disruptions.

8. Damaged, Defective, or Incorrect Deliveries

If an item arrives damaged, defective, or incorrect, contact us within 7 calendar days after confirmed delivery. Please include your order number and clear photos of the item, packaging, and shipping label when relevant.

Approved cases are handled under our Return & Refund Policy, including return-shipping assistance when the issue is our responsibility.

9. Policy Updates

We may update this Shipping Policy when our shipping services or operating requirements change. The current version will be posted on this page.

10. Contact Us

If you have questions about shipping or an order in transit, please use our Contact page or the current contact information displayed in the website footer.

This Return & Refund Policy explains when a return is eligible, how to send an item back, who pays return shipping, and how approved refunds are processed.

1. Return Window

You may request an eligible return within 30 days after confirmed delivery. Return requests submitted after the 30-day period are not accepted unless applicable law requires otherwise.

2. Return Eligibility

To qualify for a standard return, the item must generally be:

Unused, unwashed, and in its original condition.
Returned with the original packaging, tags, accessories, manuals, and other included components, when applicable.
Not specifically identified as final sale or non-returnable before purchase.

Products that show use, alteration, avoidable damage, missing components, or other conditions outside the eligibility requirements may be ineligible for a refund.

3. Product-Specific Non-Returnable Items

Some products may be non-returnable for hygiene, safety, customization, final-sale, or other product-specific reasons. Any such restriction will be disclosed on the product page or before purchase when applicable.

4. No Direct Exchanges

We do not provide direct exchange service. If you want a different item, size, color, model, or version, return the eligible original item under this Policy and place a new order separately.

5. How to Start a Return

Returns are handled by mail. Before sending an item back, contact our customer support team through the Contact page or the current contact information displayed in the website footer. Please provide:

Your order number.
The item or items you want to return.
The reason for the return.

Returns sent without required return authorization may be delayed or refused.

6. Prepaid Return Label and Return Shipping Cost

For eligible mail returns, a prepaid return label is included in the package.

For a standard return made for customer-choice reasons, the actual carrier postage charged for use of the prepaid return label will be deducted from the approved refund. We do not charge a separate restocking fee.

If the return is required because the item arrived damaged, defective, or incorrect and the claim is approved, we cover the return-label cost.

If you choose not to use the provided label when an alternative return method is authorized, use a trackable shipping service and keep your shipping receipt until the return is completed.

7. Original Shipping Charges

Original outbound shipping charges are non-refundable for standard customer-choice returns, except where required by law. If the return results from an approved damaged, defective, or incorrect item, applicable shipping charges will be handled as part of the resolution.

8. Refund Review and Processing

After the returned item is received, we inspect it and notify you whether the refund is approved.

If approved, the refund is issued to the original payment method. We generally process an approved refund within 1–3 business days. After the refund is issued, your bank or card provider may require an additional 5–10 business days to post the funds to your account.

9. Damaged, Defective, or Incorrect Items

If an item arrives damaged, defective, or incorrect, contact us within 7 calendar days after confirmed delivery. Include your order number and clear photos of the item, packaging, and shipping label when relevant.

After review, we will provide an appropriate resolution. When a return is required for an approved claim, we cover the return shipping cost.

If a shipment is refused or returned because of incorrect or incomplete customer-provided shipping information, actual carrier return, re-delivery, or related shipping charges may be deducted from an otherwise eligible refund where permitted by law.
