The NHV Hyperthyroidism Gold Support kit is certainly safe for cats with kidney disease. Unfortunately, many cats who suffer from hyperthyroidism also have some degree of kidney disease.
Many of our customers give the NHV Resthyro to their cats who suffer from both conditions with no ill effects. Bugleweed inhibits thyroid-stimulating hormones and helps to slow the heart rate, and strengthens the heart’s contractions.
These properties would only have a positive effect on the kidneys, not a negative effect, as inefficient blood flow can put a great deal of stress on the kidneys.
Some extra kidney support for your kitty with the NHV Tripsy would also be beneficial, along with the hyperthyroidism kit.
