Give your pet overall mood support with this essential amino acid

Much of today's pet food is deficient of essential nutrients, vitamins, minerals and amino acids. L-Tryptophan is one of eight essential amino acids that is lacking in most pet diets. Without a diet from whole foods your furry friend could be missing small amounts of vital nutrition and causing some problems.

How do I know if my pet needs L-Tryptophan?

Some of the most common signs or symptoms of lack of this amino acid are:

  • occasional sleeplessness
  • nervous irritability
  • muscle pain from exercise
  • uneasiness
  • weight gain

L-Tryptophan is an essential amino acid that is converted into 5-HTP in the body. 5-HTP is then converted into serotonin and melatonin, which help relieve stress and promote a natural sleeping pattern.

Is L-Tryptophan safe for my pets?

Unfortunately, today we find that there are many synthetic and chemical alternatives to L-Tryptophan on the market. Don't be fooled by these imitators.

There is no other vitamin, mineral, herb or synthetic chemical that can provide what natural L-Tryptophan does. Bios Nutrients, the makers of the L-Tryptophan I carry produces pharmaceutically pure amino acids. And they back it by providing a purity analysis certification, so you can be assured this product is safe for your pets.

Every batch of L-Tryptophan is carefully tested to ensure its purity and to guarantee the absence of contaminants.

How much should I give to my pet?

Directions for use: Take one capsule for every 50 lbs. or as directed by your veterinarian, doctor or health professional. If you have a small pet, open the capsule and sprinkle a small amount on its food. Start very small and watch for changes before adding more. When change begins to occur, stay with that amount.

Recommendation: Best if given with a snack or beverage with little or no protein. Its benefits may be enhanced with the additoin of Vitamin B6 and Niacin. It is suggested to work up to the desired level gradually. Allow 60 days for full benefit.

Suggested use: Do not exceed 6 capsules (3 grams) per day...depending on your pet's weight...unless directed by your veterinarian doctor.

CAUTION: If your dog is pregnant or nursing or has been given any medication, consult your vet before using L-Tryptophan. Discontinue use if an adverse reaction should occur.

Dog spared euthanasia and seizures stop

"I own a health food store and have my practice as a naturopathic doctor on the premises as well.

One of my patients came to me very upset about her dog and stated that he had been on phenobarbital for seizures, but it no longer was working.

She asked if there was anything I could do for her dog as she probably would have to have her dog euthanized otherwise.

She said that every time he woke up from his nap, he would have seizures. I talked to her about the dog, asking its weight and other questions, and advised that I would need to first detox the dog's liver to cleanse it of everything that had been put into its system, and then I would put it on L-Tryptophan.

The dog has been on L-Tryptophan for over 6 months, and from the first capsule taken until now, there have been no seizures at all.

Whenever I am asked about what to use for dogs with seizures, I have been recommending L-Tryptophan.

I had a call the other day from 80 miles away and the lady said that she heard I could help her dog with seizures."

--Dr. B., North Carolina

Veterinarian appreciates healthy supplements and pure ingredients

"Having been in the Health/Veterinary field for thirty years and through all the changes that have taken place and taking place now, I can tell you that even for someone like me that knows my way around the supplements it is not possible for any one person to really know what it is they are getting anymore.

I know that at this point I certainly depend on finding a company such as yours that may charge more, but the added cost is well worth it for a safe and legitimate product

... People like me need to be able to trust a company to use the best materials, do research and make healthy supplements available that truly assist in providing better health.

I'm not interested in one supplement that is so full of "everything" that I feel sick an hour later. We have a Veterinary practice as well and work with pets the same way.

I hope you continue to do the good work, and please don't start spending the bulk of your profits on fancy brochures, keep placing money back into researching the purest supplements available, and providing information the way you do now by explaining differences in formulations. etc.

We need teachers that we can trust; your web pages do a nice job of educating. Thank you to all of you."

--Kathy, Saint David, ME

Dog gets relief from post-surgery symptoms

"I am a repeat customer of BIOS Tryptophan. My dog recently needed surgery and was experiencing anxiety even after giving the prescribed pain meds.

She was extremely restless, breathless, and paced the floor, whimpering. She was weak with exhaustion, frequently toppling over, but couldn't settle down.

I called my vet and told him the situation and asked if I could give her some L-Tryptophan.

He said, "Absolutely" it will relieve her anxiety and likely let her sleep. I gave it to her and she calmed right down in about 1/2 hr. and slept 8 hours with only one waking to go out for potty.

Just a wonderful product to have in the natural medicine arsenal. Thank you."

--Jenny, South Glen Falls, NY
