Water Soluble Grand Flex + MSM contains all the ingredients in our well know Grand Flex together with 10,000 mg of MSM per dose plus a delicious apple flavoring. Many companies introduced liquid joint supplements in recent years but at Grand Meadows we found that in pre-mixed products there were serious problems in maintaining potency of ingredients and ensuring dosage accuracy. The oxygen in water breaks down many ingredients quickly. This is why veterinary pharmaceutical medications are sold in tablet or powder form. Water Soluble Grand Flex + MSM provides the ability to provide a liquid that guarantees dosage accuracy and shelf stability of all ingredients. It can be used wet or dry.
