21st Century Pet Eze Soft Chews

Hello, I have come to rely on these calming chews for my cat, and the little tub they come in or website doesn't give any more nutritional info than this below. Do you think these ingredients would at all mess with the diabetes? I only give him them when he's bad off (he has hyperesthesia syndrome) and when I do I give him 4 or 5. Happens right now about 3 or 4 times a month.

Active Ingredients per one soft chew:

L-Tryptophan 25 mg

Chamomile Flower (Matricaria recutita) 6 mg

Thiamine 6 mg

Inactive Ingredients: Brewer's Dried Yeast, Calcium Propionate, Canola Oil, Chicken Liver, Citric Acid, Corn Starch, Dried Cheese, Green Tea Extract, Mixed Tocopherols, Natural Flavors, Rosemary Extract, Salmon Oil, Sorbic Acid, Soy Lecithin, Vegetable Glycerin, Vegetable Oil, Water.

Thanks, any opinions appreciated!
