Veterinary-Grade Urinary Acidifier for Dogs and Cats
Product Description
DL Methionine 200mg Tablets are a veterinary-recommended urinary acidifier supplement used in dogs and cats to support healthy urinary function. Manufactured by V.E.T. Pharmaceuticals, each tablet delivers 200mg of DL-Methionine, an essential sulfur-containing amino acid. When metabolized, it releases sulfur as sulfuric acid into the urine, lowering urinary pH to help prevent and manage struvite bladder stones and crystals. This 1,000-tablet pack is ideal for ongoing, vet-directed urinary care.

Frequently Asked Questions
Q1: What is DL-Methionine used for in pets?
Ans: It is a urinary acidification supplement used in dogs and cats to help lower urine pH. It aids in the treatment and prevention of struvite bladder stones, which form when urine becomes too alkaline, often due to an underlying urinary tract infection.
Q2: How does the supplement work inside a pet's body?
Ans: When ingested, it releases sulfur into the urine as sulfuric acid, making the urine more acidic. This acidic environment prevents struvite stones from forming, as struvite crystals can only form in alkaline urine.
Q3: Is DL-Methionine FDA-approved for veterinary use?
Ans: It is currently not FDA-approved as a veterinary medication. However, it can be used safely in dogs and cats under the direct supervision of a licensed veterinarian in specific, appropriate circumstances.
Q4: Can DL-Methionine be given to kittens?
Ans: No, it should not be administered to kittens. Excess methionine in kittens can cause toxicity and stunted growth, as confirmed by research published in the Journal of Nutrition (1987).
Q5: How long does it take to see results?
Ans: When used alongside other treatments, it may take several weeks for struvite bladder stones to dissolve. The timeline depends on stone size, resolution of any underlying infection, and the pet's adherence to a veterinary-prescribed therapeutic urinary diet.
Q6: What precautions should be taken before giving this supplement?
Ans: It should not be used in pets with liver disease, kidney damage, pancreatic disease, or acidosis. Always discuss your pet's full medical history and current medications with your veterinarian before starting this supplement.
Q7: What are the signs of an overdose in dogs?
Ans: Signs of overdose in dogs may include vomiting, loss of balance, weakness, tremors, stiff or exaggerated walking movements, and disorientation. Contact your veterinarian or an animal poison control center immediately if an overdose is suspected.
Q8: Can the supplement help with urine odor?
Ans: Yes, acidifying the urine as a secondary benefit also helps reduce urine odor in pets. This makes it a useful supplement for pets that have strong-smelling urine associated with urinary health concerns.
Q9: Should this supplement be given with food?
Ans: Yes, it is generally recommended to give it with food to reduce the risk of digestive upset. Your veterinarian may also advise dividing the daily dose across multiple meals, and your pet should always have access to fresh water.
Q10: Can this supplement be used alongside other medications?
Ans: Giving it with certain medications can result in health risks. It is essential to inform your veterinarian about all medications and supplements your pet is currently receiving before starting this product.
