A natural source contains 'co-factors' that come with the nutrient in nature. For instance, co-factors that are usually found with Vitamin C are various bioflavonoids. The bioflavinoids are concentrated from the natural source as carefully as possible. No extreme heat, pressure, or possible toxic solvents are used. There are no sugar or chemical tablet coatings. The nutrients are prepared from high quality raw ingredients. No artificial chemicals are added. Harsh binders and fillers do not hinder absorption. This is why natural source vitamins cost more.
Synthetic vitamins are made in a laboratory setting from coal tar derivatives. No co-factors are present. Most of the pet supplements sold on the market today are synthetic.
Give me an example:
Vitamin C that is found and isolated from oranges is identical to the vitamin C derived from other plant sources, largely because plants containing vitamin C biosynthesize the substance in much the same manner. However, when Vitamin C was first isolated and produced in a supplement form, we did not know about bioflavonoids. They were discovered later. It was found that in nature, bioflavonoids always accompany Vitamin C. In fact, the bioflavonoids are essential for better absorption. They increase bioavailability by 30%. This suggests we should feed our dogs the natural form of vitamin C. What else don't we know?
When feeding your dog organic vegetables such as broccoli, carrots, or plants and herbs such as Green Barley, sea vegetables, dandelion etc., there is no label that indicates how many I.U's or milligrams of this, that, or the other nutrients these plants contain because they are in their natural, whole, organic form, in just the right amounts, the way nature intended. The ideal source of nutrients comes from organic plant sources in their whole natural form, not from isolated or man-made chemical source. Recent studies (in Finland) suggest that isolated natural vitamins may not be good for the health our our pets.
What are vitamins anyway?
Vitamins are living enzyme complexes that naturally produce biochemical reactions in the body. Synthetic Vitamins are chemicals that produce drug reactions in the body.
Canine supplements, as the word clearly states, are meant to supplement a highly varied diet of whole, unprocessed foods.
This is why we love our Green Power! Organic and the whole food - carefully dried and finely powdered for easy absorption. It's the Natural Canine Vitamin!
