Bovine Colostrum

Colostrum contains the hormone Proline-Rich-Polypeptide (PRP), which could either stimulate an underactive immune system, or down regulate an overactive immune system. The down regulation is important in autoimmue diseases, including arthritis and allergies as the overly active immune system could either fail to recognize its own cells from foreign molecules, attacking its own tissues (autoimmunity), or show an exaggerated response to a normally harmless molecule. Bovine colostrum is essential colostrum that comes from the cows.

PRP regulates the activity of the immune system, reducing the allergic symptoms by inhibiting lymphocyte (white blood cell~and T cell overproduction that overreact in an allergic reaction. PRP seemingly helps to create special helper T cells and suppressor T cells that suppress and switch off the immune responses that trigger allergies.

PRP is also highly anti inflammatory, helping not just with allergies but other inflammatory conditions like arthritis.

Colostrum has the ability to control the health of the gastrointestinal (GI) tract by helping to seal the lining so undigested food is unable to pass through to cause inflammation and allergy symptoms. It could also help reverse gut irritation and chronic health issues, incuding Candida albicans, or yeast. As colostrum contains probiotics and has antibiotic activity, it is able to help restore a healthy gut flora, which is crucial to healing leaky gut.

Cytokines in colostrum (Interleukins, Interferon, and Lymphokines) also have a role in treating cancer. Interferons and Interleukins enhance the body’s response to cancer by activating special white blood cells that find and destroy cancer cells. They are also thought to inhibit cancer cell growth, even killing them (apoptosis).

Colostrum also contains a special protein called Lactalbumin, which apparently causes apoptosis of cancer cells while leaving the healthy ones to thrives. On top of that, colostrum supports the immune system by helping to fight viruses and infections.

Colostrum contains a large amount of Immunoglobin A, D, E, G and M. There are also called IgA, IgD, IgE, IgG and IgM. IgG fights against bacteria and toxin buildup, while IgM destroys bacteria and IgE and IgD fight viruses.

Colostrum also contains Lactoferrin, another substance that fights viruses and bacteria, is anti-inflammatory and has a role in treating and preventing cancer. The antioxidant phytic acid found in colostrum prevents iron from reaching and feeding cancer cells.

In fact, the same immune-boosting properties that help prevent and treat cancer and allergies could also protect yyour pet from viruses such as bordetella (kennel cough), parvovirus, Leptospirosis, Lyme disease and more.

Colostrum contains growth factors, which help the newborn grow and development. These very same growth factors stimulate wound healing. When used in an external application, aside from wound healing, skin growth and cellular repair is promoted. Thanks to its antibacterial properties, it helps prevent and heal infections.

Topically, colostrum could be used for dermatitis, skin infections, gingivitis, oral infections, ear infections, abscesses, cysts, insect bites, even surgical wounds.

NON-FROZEN ITEMS SHIPPING POLICY

Singapore Orders

Non-frozen items could enjoy FREE delivery with orders $38 and above.
Non-frozen items are delivered by third-party courier partners within 3 working days.
Third-party courier partners may or may not attempt to reach you at the contact number that you've submitted upon delivery.
If no one is present or uncontactable for further instructions, your package will be left at the riser, door, gate, security, or a location determined appropriate by the courier.
If other arrangements are preferred and necessary, please leave us a remark or contact us right after you have placed your order.
For orders above $150, we will be using reasonably reliable couriers (in line with our duty under the Singapore Sale of Goods Act) that allow high-value compensation in the event of parcel loss.
For orders above $150, should there be theft suspected in your area, based on the courier that we will be partnering with, we may require you to make a police report for submission for a claim.
Alternatively, you may also opt for Self Collection.

Note: Under Singapore's Sale of Goods Act (Cap. 393), once we hand over the parcel to a courier, the law presumes this as "delivery to you". Once the parcel is delivered to the shipping address, and proof of delivery is provided (including photo confirmation), that is legally considered delivered to you by the courier company.

The courier's default "drop-off point" will be based on the address you provided + visible drop-off point, unless we instruct them otherwise through the delivery system app; failing to read a handwritten note usually does not create legal liability. So if you did not give us specific instructions (eg, "Put parcel where"), we were not aware of any preferred or safer drop-off point, the risk of loss, theft, or damage passes to you at that point. We are no longer liable for parcels lost after successful delivery when no delivery instructions were provided.

This shipping policy, which is part of our contract with you, aligns with the Singapore Sale of Goods Act's flexibility, requests that you give delivery instructions to help us and the courier to place parcels more securely. If no such instruction was provided, we cannot legally be held responsible for loss or theft after the courier has delivered to your premises with POD given.
