The most important supplement for you is the one that your body is lacking, and it may be lacking because of improper diet or other chemistry-related issues. It is advisable to have a blood test so that you can accurately pinpoint your own deficiencies.
Every single nutrient, macro or micro, is available for human beings from a plant source. Deficiencies never require the intake of animal-based foods. In some cases the animal may have a concentration of the micronutrients, because flesh material is a concentrated and dense matter. However, the concentration of micronutrients in flesh foods brings along with it the toxins in the flesh that were present at the time of the animal’s death. If the micronutrient you are seeking is not available in the plant kingdom as food for humans, it is not needed. No matter what anyone claims, you do not need it!
The golden rule of nutrition is as follows: As long as you are getting enough calories from a broad spectrum of plant-based foods and there is not a pre-existing chemistry condition, you will get enough of the micronutrients you need from that food.
