HI, thanks for using healthcare magic
Your hesitancy at taking another drug is understandable because of the potential side effects. At present however, there are no herbal or other supplements that would cause a reduction in your viral load
You are right in stating that your load is low but a further reduction would be associated with reduced chance of transmission and improved status.
You may want to consider trying to medication, if it is intolerable then you can speak to your doctor.
I hope this helps
