Actually, the brand definitely makes a difference. A lot of "cheaper" brands of vitamin C contain sugar, artificial flavors/colors, starch, etc. Not to mention the fact that in my experience, these cheaper brands have no effect on me. I actually went through an entire bottle of 1,000mg Vitamin C from a well-known store brand years ago when I was battling a very bad cold. Nothing happened at all. So, I ordered a bottle of
Citrus Bioflavonoids and in less than 24 hours, my cold was completely gone.
I've had many friends and customers tell me similar stories when they switched to using NSP products. The quality, purity and potency of a product makes ALL the difference in the world.
This goes for any type of herbal, vitamin or mineral supplement. For example, with herbs, different parts of the plant may have different effects or may be of no effect at all. So although different companies may sell a product by the same name, the product itself may have little to no effect based on what's in it (or what's not in it).
This is why it's so important to get "quality" products. Plus, you don't want to have to worry about pesticide residues, heavy metal contaminants, artificial ingredients, carcinogenic dyes, etc.
Think about it...you wouldn't buy the cheapest, watered-down gasoline for your car, right? Isn't your body even more important?
Whether you switch to Nature's Sunshine products or not, I urge everyone to get your supplements from a company that invests in making high-quality products, and preferably (considering we all have mercury poisoning) from a company that adheres to California's Proposition 65 (the strictest manufacturing regulations in the U.S. for heavy metal contaminants in products).
