About Four Sigmatic - CALM Organic Cacao Mix with Reishi Mushrooms

Four Sigmatic's CALM Organic Cacao Mix combines ceremonial-quality organic cacao with Reishi mushroom extract, formulated to support relaxation and a calm, balanced mood. Each serving delivers a dual-extracted Reishi preparation alongside naturally occurring cacao compounds, making it a functional evening beverage for adults seeking a non-caffeinated wind-down ritual.

Why It's Worth Considering: The dual-extraction process is designed to improve availability of Reishi's bioactive beta-glucans and triterpenes, and the organic cacao base provides a genuinely palatable format without relying on stimulants.

Frequently Asked Questions

  • Fruiting body is the actual mushroom cap/stem — it contains higher concentrations of beta-glucans, triterpenes, and active compounds. Mycelium is the root-like network that grows on grain substrate — products labeled 'mycelium on grain' may be 50-70% starch filler. For therapeutic use, always choose fruiting body extract or dual-extracted products.

  • Cognitive function: Lion's Mane (stimulates NGF for nerve growth). Immune support: Turkey Tail (highest beta-glucan content) or Chaga. Stress/sleep: Reishi (calming, adaptogenic). Energy: Cordyceps (ATP production). Cancer support: Turkey Tail (PSK/PSP research). Multi-purpose: a blend containing all five.

  • Take with food for best absorption. Hot water extraction activates beta-glucans (the immune-active compounds). If using a powder, adding it to hot coffee or tea mimics the extraction process. Capsules of pre-extracted mushroom are ready to absorb. Dose varies by mushroom: Lion's Mane 500-1000mg, Reishi 1000-2000mg, Turkey Tail 1000-3000mg.

  • Yes — medicinal mushrooms have thousands of years of traditional use and modern clinical evidence supporting daily consumption. They do not cause tolerance or dependence. Most people take them continuously as part of their daily supplement routine. The main caution is for those with autoimmune conditions or on immunosuppressants.
