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! ## Features - Dee Cee Laboratories Formula 303 Natural Relaxant, natural relief for muscle spasm, tension, and stress. - Formula 303 is an all-natural herbal remedy that harnesses the medicinal properties of valerian root, passion flower, and magnesium to provide you with relaxed muscles, stress relief, and natural relief from muscle relief, joint relief, leg cramp relief, and stress. - A perfectly formulated balance of Valerian Root, Passion Flower, and Magnesium for sore muscle relief and much more. - Formula 303 is made from natural ingredients and may have a distinctive earthy odor, taste, and color of tablets may vary. - Gluten Free, Non-GMO manufactured for almost 60 years in the USA, in an FDA registered and inspected facility in full compliance with current Good Manufacturing Processes. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0016L0ZZC | | ASIN | B0016L0ZZC | | Age Range Description | Adult | | Best Sellers Rank | #8,285 in Health & Household ( See Top 100 in Health & Household ) #7 in Valerian Herbal Supplements | | Brand Name | Dee Cee Laboratories | | Container Type | Bottle | | Customer Reviews | 4.4 4.4 out of 5 stars (9,482) | | Date First Available | March 26, 2008 | | Dosage Form | Tablet | | Is Discontinued By Manufacturer | No | | Is Product Expirable | Yes | | Item Form | Tablet | | Item Weight | 0.07 Kilograms | | Item model number | No Model | | Legal Disclaimer | MUST BE 18 TO PURCHASE | | Manufacturer | Dee Cee Labs | | Manufacturer | Dee Cee Labs | | Manufacturer Part Number | Formula 303 pain relieve natural muscle | | Material Features | Genetically Modified Organism (GMO) Free, Gluten Free | | Number of Items | 90 | | Package Dimensions | 3.43 x 1.69 x 1.65 inches; 2.4 ounces | | Package Quantity | 1 | | Recommended Uses For Product | Pain | | Total Servings Per Container | 90 | | UPC | 052301303908 | | Unit Count | 90 Count | ## Product Details - **Brand:** Dee Cee Laboratories - **Item Form:** Tablet - **Item Package Quantity:** 1 - **Manufacturer:** Dee Cee Labs - **Package Information:** Bottle ## Images ![Dee CEE Labs Formula 303 Maximum Strength Tablets, 90 Tablets; All-Natural containing Magnesium for Sore Muscles, Passion Flower, and Valerian Root - Image 1](https://m.media-amazon.com/images/I/61chS66Z8UL.jpg) ## Available Options This product comes in different **Size** options. ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Highly effective for pain, sleep, & nervousness! :-) *by J***E on February 22, 2026* Formula 303 was recommended by my chiropractor and it is truly amazing!
