Evening Primrose Oil Capsules are a natural dietary supplement rich in essential fatty acids (EFAs). These polyunsaturated fats, given as a supplement to a good diest, are excellent to promote a healthy coat and skin condition and help to alleviate dry and irritated skin, scurf, dermatitis, and other allergy based skin problems, which can be caused by flea infestation. Also may be beneficial to general good health. EFAs also promote coat growth, especially when moulting, and in cases of heavy hair loss.
