In one sentence, describe what the following article is about:

Pick a form that suits your comfort level. A powder or tincture may be ideal if you do not like swallowing pills. Only buy ashwagandha from a reputable vitamin supply shop or a natural health food store to ensure you are consuming a high quality supplement. Read over the ingredients list to confirm there are no dyes, colorings, additives, or preservatives in the product. You want to buy a product that is as pure as possible.  You should also check the Daily Value (DV) percentages on the label to make sure you are getting 100% DV. This means you are getting the maximum amount of nutrients in each serving of the supplement. You can also look for a “USP Verified” label on the supplement. This means it has been inspected by the U.S. Pharmacopeial Convention and that it contains the ingredients listed on the label. It also means it has been manufactured in sanitary and well-controlled conditions. Make sure there is clear contact information for the supplier listed on the label. Check that the supplier is highly rated online and has positive reviews by consumers. You can ask your doctor to recommend a supplier that they trust so you know the ashwagandha is coming from a reliable source.
Look for ashwagandha in capsule, powder, or tincture form. Make sure the first ingredient on the label is ashwagandha. Confirm the supplier is legitimate and reputable.
