Many companies now provide supplement formulas intended for specific health needs.
This saves you the trouble and expense of taking multiple pills for each health concern. In addition, certain combinations of vitamins, minerals, amino acids and herbs work better when taken together - they work synergistically. Because they work better together, you can take a lower dose. There are many formulas to choose from for many health needs - bones, blood pressure, weight control, energy, blood sugar, etc. All the research has been done - you just take them.
