MSE Natural Defense (All sizes)

MSE Natural Defense (all sizes)

FREE SHIPPING FOR DOMESTIC ORDERS (shipped by USPS or UPS ground)! MSE Natural Defense (formerly called "MSE Hypo Defense") is a purified and palatable probiotic for pets with allergies and other special needs, for those that experience stress on a daily basis, or for maximum control of litter box odor (mainly ammonia). It can help control loose stools and diarrhea, which are often a symptom of Exocrine pancreatic insufficiency (EPI) and Irritable bowel syndrome (IBS). MSE Natural Defense has also been shown to reduce the symptoms of allergy in most dogs.

The body reacts to allergens (both food and environmental) as if they were pathogens. Allergies are actually an immune response that results in chronic scratching and biting. Constant irritation and scratching is stressful, and stress reduces the ability of the body to fight infection. This means an allergic pet is trapped in a vicious cycle that leaves them vulnerable to infection. Break the cycle by feeding MSE Natural Defense every day. MSE Natural Defense contains a substance that has been shown to block the immunoglobulin that triggers allergy symptoms. Most allergic dogs fed MSE Natural Defense had reduced symptoms after four days.

MSE Natural Defense is hypoallergenic, reinforces compromised immune systems, and reduces symptoms of allergy in most dogs. MSE Natural Defense has the same microorganisms as MSE Daily Boost, but at approximately 3 times the concentration. Like MSE Daily Boost, MSE Natural Defense is intended for daily use. Not recommended for pets with asthma. MSE Microbial paste should be used instead.

MSE Natural Defense can be safely frozen. Freezing prolongs microbe viability. However, repeated thawing and refreezing is not recommended. MSE Natural Defense may be frozen in the original shaker. FREE SHIPPING!
