Product
Yes! Our products are manufactured in the US.
Crucible blends Epsom Salt (magnesium sulfate), Magnesium Flakes (magnesium chloride), and Dead Sea Salt to provide a full-spectrum mineral profile. We also add MSM and glucosamine to support joint health and recovery. Finally, we add sandalwood fragrance oil and peppermint essential oil to improve breathing and circulation.
Epsom salt only provides magnesium and sulfate. Crucible delivers those and much more—chloride, potassium, calcium, bromide, and added joint-support compounds for complete post-workout recovery.
Crucible is formulated for performance, giving you what you need to recover, and nothing you don't. We keep it clean and effective—no dyes, no parabens, and no unnecessary fillers. Most of the ingredients are natural, including naturally occurring minerals and essential oils. We include proven joint-support compounds like MSM and glucosamine that aren’t botanicals but are scientifically proven and trusted for their recovery benefits as well as a sandalwood fragrance oil to give it a bold, grounding scent.
Never. Crucible is cruelty-free. We love our furry friends.
Usage
We recommend 1.5 cups in a standard-size tub. Use more after intense workouts or longer training sessions.
For best results, soak for 20 minutes.
You should use Crucible after any really intense workout or up to 3–4 times per week as part of a consistent recovery routine.
Yes! Try a concentrated foot soak in a bucket or create a hot compress using a muslin bag or washcloth.
Our standard 3lb bag provides 4 uses if used according to the directions by adding 1.5 cups per bath.
For maximum mineral absorption, we recommend a warm to hot bath—around 95°F to 105°F (35°C to 40°C). Warmer water helps open pores and improve transdermal uptake of magnesium and other minerals. If you're recovering from a brutal session and prefer an ice bath, you’ll still get benefits—but hot water is best for full absorption.
Audience and Use Cases
Not at all. Crucible is designed for anyone who trains hard and demands more from their recovery—no matter their gender.
Absolutely. Whether you’re lifting, running, cycling, or grinding through WODs, Crucible supports muscle repair, electrolyte balance, and joint recovery.
Many customers with chronic joint issues or post-injury inflammation report noticeable benefits from MSM and glucosamine. As always, consult a doctor if you have a medical condition.
Yes. Crucible works in both hot and cold water. While heat helps with mineral absorption through the skin, using it in an ice bath still delivers benefits—especially for skin hydration, inflammation reduction, and joint support. Think of it as leveling up your cold plunge with added recovery fuel.

Safety & Sensitivities
Yes. If you notice any discomfort after use, we recommend talking to a skin-care professional and reducing the amount of our product you add to your bath. If you have highly sensitive skin or allergies, check the ingredient list and test a small amount first.
We recommend checking with your healthcare provider before use during pregnancy or postpartum recovery.
Crucible dissolves cleanly, but Dead Sea salt may leave minimal trace minerals behind. Just rinse your tub after use.
