Vitamins and minerals come in many different forms, some of which are more readily absorbed in the digestive tract than others. High quality supplements will use the most bioavailable, active form of the vitamin to ensure that your body can absorb and use it appropriately.
"High quality supplements go through rigorous quality control..."
A recent study you can read here looked at claimed doses on the label of vitamin supplements, compared with the actual dose in each pill, and found an overwhelming discrepancy with potency varying from 9% - 140%. High quality supplements go through rigorous quality control to ensure that each and every tablet, capsule, or spoonful delivers exactly what the label says.
"Buying a good supplement will save you money..."
3. Correct Dose
Ok, so if the label matches the pill, then it’s a good supplement, right? Wrong. A good supplement will not only ensure the dose listed is what's in the bottle, but also ensure that this is a sufficient dose to see benefits. For some products, you may need to take up to 10 pills or more in order to achieve a therapeutic range that will be beneficial to your health. Buying a good supplement with a high dose will mean you only need to take 1 or 2, and SAVE you money.
4. Fillers and Toxins
Average supplements often have many fillers which people may be allergic or sensitive to. These fillers may also hinder the absorption of other ingredients in the formula. Good quality supplements will guarantee a hypoallergenic formula, with no gluten, dairy, corn, sugar and other allergens. Many supplements may also contains toxins like mercury and lead, as you can read here. Professional supplements will ensure no contamination, and no toxins.
5. Backed by Research
High quality supplements have research to support their benefit in two different ways. A good company will critically analyze a wide variety of research and include appropriate doses and forms of well-researched ingredients in their formulas. A great company will conduct their own research on their formulas to ensure that the product yields the expected benefit. Using these products will obviously give better results, but I also believe that supporting these companies is important for the industry.

I hope you found this helpful and will think twice next time you buy supplements.
