The best use of supplements is to correct deficiencies and temporarily help treat specific conditions, with the ideal desired outcome being to ultimately depend on a good all around diet and lifestyle to maintain good health. In some instances certain conditions may require continued use of supplements - and eye conditions could well qualify as conditions that require at least some dietary restrictions and continued supplementation; however, in many instances and conditions that should not be the case. What can indeed happen is that the body becomes dependent on supplements to help perform functions that a healthy body normally should, as well as dependent on supplements to treat symptoms instead of actually effecting a lasting cure. Going cold turkey from all supplements and noticing immediate negative results is a pretty good indication that your treatment has not provided permanent relief and may in fact be stringing you along. One way to guard against becoming dependent upon supplements is to periodically take alternating breaks from individual supplements ranging from one or two days to a week.
Though a restricted diet may be a wise thing if it is restricted in such a way as to avoid unhealthy foods, if it is so restricted that it avoids essential nutrients it could contribute to continued dependency on supplements. In most instances, avoiding unhealthy foods, eating a healthy nutrient dense diet from uncontaminated food sources and perhaps the regular use of a good food derived nutrient such as intraMAX and a superfoods powder should provide all the nutrients needed and then some, without having to rely on a basket full of supplements.
Without making any judgment whatsoever on your holistic doctor, I will point out that holistic and alternative doctors can and do get caught up in the same practice as mainstream doctors - treating their patients in such a way as to insure that they keep coming back regularly and continuing to market medicinal items they profit from. I will also observe that two years is an awfully long time to still have to depend on a highly restricted diet and multiple supplements.
Might I ask what the supplement is (or what it contains) and whether or not that is the only supplement you take? Also, could you tell what the dietary restrictions are?
Is there a reason (such as weight issues) that you are on such a calorie-restricted diet? There is virtually no way to get all the nutrients you need on that few calories and thus the diet itself creates extra needs for supplemental nutrients. Also, are both of you gluten and lactose intolerant? That would explain the restrictions on dairy and grains - though amaranth is itself a grain (and a healthy one too). Hopefully your rice is healthy brown or black rice and not just white rice. Beans are good, but they can be even better with some healthy fats included.
If I were you, and had no specific condtitions and issues that required addressing, and wanted to get off all the supplements, I would try the wonderful all around nutritional product intraMAX, which should supply all the minerals, vitamins and other essential nutrients you need. In addition, I would consider a good superfoods powder such as the Dr. Schulze formula. Unless you have weight issues (after two years?), I would look at a healthy breakfast smoothie made with raw organic goat milk, a tablespoon of blackstrap molasses, a raw organic egg and perhaps raw honey to taste. You can add a scoop of the superfoods powder to supercharge it. Instead of going "cold turkey" off your present supplements, I would reduce them by half and take half of the items I suggested and then gradually wean off the supplements and take the intraMAX daily as well as frequent (every other day at least) scoops of the superfoods powder and the aforementioned breakfast smoothie two or three times a week.
Note that I am no doctor and certainly the web is not a substitute for someone working closely with you. Nevertheless, I can see no reason to keep depending on so many supplements and such a low calorie diet. Better by far to have at least 2000 calories a day and get plenty of physical activity.
I hope that helps,
