It is possible. More is not necessarily better. If you've been prescribed these supplements by a qualified practitioner for a specific purpose and for a certain period of time, along with an appropriate dosage, and for your specific dosha type (constitution), then it's probably fine and good. If not, then you should be cautious and seek the guidance of an Ayurvedic professional. Certain supplements are good for short-term periods (for example, to reduce your pain) and may not be suitable as a longer term treatment.
