Milk Thistle Extract

Milk Thistle Extract| Bulk Price

  1. English Name: Milk Thistle Extract (it’s a concentrated extract from the seeds of Silybum marianum—a spiky plant with purple flowers and white-veined leaves! The name “milk thistle” comes from the milky sap that oozes when its leaves are broken. The star here is “silymarin,” the compound that gives it all its benefits.)
  2. Specification
    • Active Content: ≥ 80% silymarin (HPLC tested—this is the gold standard for liver support; some premium grades hit 90% for stronger effects)
    • Solubility: Slightly water-soluble (mixes best in warm liquids like tea or smoothies; dissolves fully in ethanol for tinctures)
    • Moisture: ≤ 5% (keeps the powder dry, so it doesn’t clump or lose potency—stable for 2+ years sealed)
    • Heavy Metals: ≤ 2 ppm (ultra-safe for oral use—meets global herbal supplement and organic standards)
    • Purity: No additives, fillers, or artificial colors—just pure milk thistle seed extract (vegan-friendly and gluten-free)
  3. Appearance: Light yellow to tan fine powder with a mild, earthy, slightly bitter aroma—definitely not a yellowish-white solid with chocolate scent! It smells like dried herbal seeds (subtle, not overpowering)—no sweet or chocolate notes at all.
  4. CAS NO.: N/A (it’s a plant seed extract, not a single chemical; its key compound “silymarin” has CAS 65666-07-1, but the full extract has no single CAS)
  5. Lead time: 3–7 Working Days (we stock the standard 80% silymarin grade—fast for supplement brands, wellness shops, and herbal product makers)
  6. Package:
    • Small sizes: 10g/100g amber glass jars (light-proof to protect silymarin) or 30-count veggie capsules (easy to take on-the-go, no mixing)
    • Bulk: 25kg food-grade drums (lined with plastic—27 drums per tray; includes desiccants to keep moisture out and preserve benefits)
  7. Main Market: Global—Europe (liver support supplements, herbal remedies), North America (wellness blends, detox products), Asia (traditional health formulations, functional drinks). Popular with people looking to support liver health (like those who drink occasionally or take medications) and anyone into natural wellness.
  8. Applications & Main Benefits
    • Dietary Supplements
      • Liver Support Capsules: 200–400mg per serving (the most common use—supports healthy liver function; helps the liver process toxins)
      • Detox Blends: Paired with dandelion or artichoke extract (gentle detox support—no harsh “crash” like some detox products)
      • Antioxidant Supplements: Added to daily blends (silymarin is a powerful antioxidant—protects cells from damage)
    • Functional Beverages
      • Herbal Teas: Stir 1 tsp into hot water (sweeten with honey to cut bitterness—calming way to support liver health)
      • Wellness Shots: Mixed into green juice shots (quick nutrient boost—ideal for busy days)
      • Smoothies: Blended with spinach, banana, or almond milk (masks the mild bitterness—easy to work into morning routines)
    • Traditional Wellness
      • Herbal Tinctures: Diluted in ethanol (fast-acting—drops under the tongue for targeted support)
      • Topical Salves: Small amounts mixed into skin creams (soothes mild skin irritation—traditional use for minor burns or rashes)
    • Pet Wellness
      • Senior Pet Supplements: Tiny doses (50–100mg) in dog/cat vitamins (supports liver health in older pets—eases age-related liver strain)

Why Milk Thistle Extract Is a Wellness Staple

  • Liver Hero: It’s one of the most studied herbs for liver support—trusted by herbalists and doctors alike for its gentle, effective benefits.
  • Antioxidant Power: Silymarin fights free radicals—protects not just the liver, but cells all over the body.
  • Gentle & Safe: No harsh side effects (when used as directed)—safe for long-term use for ongoing liver support.
  • Versatile: Works in capsules, teas, or smoothies—easy to fit into any wellness routine.

Quick Tips & Safety Notes

  • Bitterness Hack: If you’re mixing the powder into drinks, add a splash of lemon or a pinch of honey—cuts the mild bitter taste.
  • Timing: Take it with meals (especially if you have a sensitive stomach)—food helps with absorption and reduces any potential upset.
  • Storage: Keep in a cool, dark place—light and heat break down silymarin (that amber jar is key for preserving its power!).
  • Check with a Pro: If you have a serious liver condition or take prescription meds, talk to a doctor first—milk thistle can interact with some drugs (rare, but safe to confirm!).
