For Optimal Results

BioSENIOR combined with BioFATS provides a powerful support to your pet’s energy levels, wellness and immune system in the regulation of inflammatory response as well as joint and connective tissue support.

Flax, Sunflower & Sesame Seed Fibre
Lignan-rich blend that encourages nutrient absorption from supplements and food, and functions as a hormonal support for spayed and neutered pets

Maintains healthy connective tissue with antiinflammatory and analgesic properties

Bromelain is active both in the acid environment of the stomach and the alkaline environment of the small intestine. This may make it particularly effective as an oral digestive aid for those pets that do not digest proteins properly. Since it is primarily the proteins in foods that cause food allergies, bromelain might reduce food allergy symptoms as well

Reduces bacterial translocation, and increases the protein synthesis of enterocytes, enabling them to increase their rate of self-repair. Supports normal immune system function and help support normal recovery from exercise; helps maintain normal body composition. Repairs damaged intestinal mucosal barrier

Amino Acids – Taurine, Cystine  
Building blocks in the production of hormones, antibodies, muscle and structural tissues.

Fucus Vesiculosus (Bladderwrack)

What does “not for long-term use” mean?
This purposely vague description is neither clearly defined nor is it a fixed duration of time. It may include a time frame of several days, weeks, months or even years. Health Canada requires the use of this statement on our labels as part of the Interim Notification Program (The Program) for Low-Risk Veterinary Health Products (LRVHP). This statement is summoned when certain ingredients are present in a product, such as enzymes or various herbal extracts. In BioSENIOR it is the Bromelain that requires the statement.

Dietary supplements, such as BiologicVET’s, are quite safe to take every day. However, it is best to keep in mind that the long-term use of any supplement should be discussed with your trusted veterinarian. They will help evaluate and assess the pros and cons of supplementation based on your animal companion’s unique and individual needs.

Administer orally. Mix one half scoop (2.5 g) per 4.5 kg (10 lb) of body weight to a maximum of 6 scoops daily. Add to raw, moist or dry food. If desired, add water to make a gravy-like paste. For best results, divide between two meals.

NN.DWY2   Low Risk Veterinary Product (LRVHP) 

Interim Notification Program 
This program is a temporary measure pending the amendment of the Food and Drug Regulations to improve the regulation of low risk veterinarian products (LRVHPs). The INP applies to LRVHPs for sale in Canada that are for use in cats, dogs, and horses that are not intended for food. An LRVHP may only contain substances that are included on the List of Substances, including homeopathic medicines, botanicals, vitamins, minerals, fungi, bacteria, etc.

Companies apply to the INP to obtain a Notification Number (NN). A third party administrative organization reviews the ingredients and the content of the product and label. Upon the satisfaction of the established requirements, a Notification Number (NN) is issued. Participation in the INP is voluntary. Given the INP safeguards, Health Canada considers it unlikely that a product satisfying all applicable requirements could present a significant risk to the health of humans or animals.

Low Risk Veterinary Health Products List of Substances 
The List of Substances (The List) includes substances that have been evaluated as admissible or non-admissible. Admissible substances are substances determined to represent a low risk when used appropriately and according to certain conditions such as route of administration, quantity or duration of use, and in doses at generally accepted safe and effective levels that are supported by available literature. Health Canada considers it unlikely that a product containing only admissible substances and that satisfies all other applicable requirements could present a significant risk to the health of humans or animals. Substances that have been altered through biotechnology and/or intended for use in food producing animals (such as cows, swine and poultry) have not been considered and are excluded from the List of Substances.

LRVHP GMP Guidelines – Good Manufacturing Practices 
This document is intended to provide guidance on the Good Manufacturing Practices (GMP) requirements for a Low Risk Veterinary Product eligible for Notification. The following link is a list of GMP requirements to manufacturers, packagers, labelers, importers or distributors, as the case may be. These requiremets are quite similar to the requirements applicable to Natural Health Products used in humans.

BioFIBRE Delivery System—Nutrition Facts 
The delivery system of BioSENIOR is a certified organic blend of defatted flax, sunflower and sesame seed providing the good bacteria in the intestinal tract of the dog or cat a valuble prebiotic food source to improve their immune system. This fibre also supplies plant estrogens called lignans that the good bacteria convert into mammalian estrogens balancing hormone function in the dog and cat especially when they have been spayed or neutered.

Each scoop (1 tbsp) will provide at minimum 20 mg of lignans, enough for the Vet recommended amount of 1 mg of lignan per lb of pet weight. By improving the intestinal tract function, immune system, and hormonal function of the dog or cat there is better absorption of the nutrients from the formula as well as from the food they are eating allowing the BioSENIOR formula to begin to work in a very short time.
