Review: Highly effective for pain, sleep, & nervousness! :-) - Formula 303 was recommended by my chiropractor and it is truly amazing! I have been taking it for over a year for neck pain (from a horse injury 20 years ago). It eases the pain and helps me achieve restful sleep. I also take it for occasional nervousness. I do find that it works best if I take a dose or two throughout the day, and then a dose at bedtime. It smells exactly like the valerian plants in my garden (very stinky), but it reassures me that it actually includes true valerian root. Therefore, I don’t mind the smell at all—because it’s so effective.
Review: Works great for anxiety, sleep. - Good for anxiety, stress or pain. Could not stop worrying to sleep till I took two of these. Wow it actually worked!

## Questions & Answers

**Q: Is this kratom? If not is it similar**
A: Not kratom, not similar. Not good.

**Q: If your product contains no Kratom, then why is your product listed first under Kratom?**
A: Kratom isn't available on Amazon anymore, so when you search for it, you pull up products with desired results that are comparable. BOO FDA!!!

**Q: All this is is valerian root? You can get that at Walmart for $6-$8 bucks. Good grief.**
A: This is a combination of three ingredients: Valerian, Passiflora, and Magnesium Carbonate. The reasons this costs what it does versus the supplements at Walmart are three-fold: 1. The process used by Dee Cee Labs makes these ingredients more bioavailable; 2. Passiflora (passion flower) is more difficult to find; and 3. The ingredients are in higher concentration than those you'll find at Walmart. Both the Valerian and Passiflora are at Quad Strength in the Formula 303.

**Q: How do I return this for the guarantee? It makes me jittery and angry and gives me a headache**
A: You can first contact the seller to see if they’ll take care of you directly. This seller has a good record of taking care of the customer but if for some reason they won’t then you simply hit return/replace on the order details for the purchase in your order history.

There’s a very small return window on most vitamins though with all retailers because they have to be destroyed once they’re opened if returned by law so if you’re past that window unfortunately Amazon may not be able to help either.
