Description

Barth Neutral Bicarbonate Bath Tablets 9pcs is a medicated carbonated bath supplement for tired, fatigued, and circulation-compromised skin — each tablet dissolves in bath water to create a neutral bicarbonate CO₂ bath that mimics therapeutic carbonated spring water found at Japanese onsen. Bicarbonate ions penetrate the skin surface and promote circulation from within, warming the body more deeply and for longer than plain hot water.

  • Sodium Bicarbonate — generates bicarbonate ions penetrating the skin to stimulate peripheral blood circulation
  • Sodium Carbonate — maintains neutral pH that maximises ion absorption efficacy
  • Vitamin C (Sodium Ascorbate) — preserves bath water CO₂ and provides skin antioxidant benefit
  • 9 tablets — trial size; approximately 9 bath sessions with one tablet per 180L standard Japanese bath

How it works: CO₂-enriched bath water creates higher partial pressure of carbon dioxide around the body. CO₂ penetrates the stratum corneum and diffuses into capillary blood, triggering vasodilation as the body attempts to exhale the surplus. This vasodilation warms the body from the inside and maintains the warming effect for hours after the bath — longer than plain hot water bathing alone.

9-tablet vs 30-tablet vs 90-tablet: All three contain the same formula. 9 tablets is for trying BARTH for the first time. 30 tablets covers one month of nightly bathing. 90 tablets covers three months at a significantly lower per-tablet cost — the most practical choice for committed regular users.

Known in Japan as BARTH 中性重炭酸入浴剤 9錠.

Key Ingredients
  • Sodium Bicarbonate: Active medicinal ingredient that promotes circulation and relieves fatigue.
  • Sodium Carbonate: Works to stabilize the water's neutral pH for maximum ion absorption.
  • Vitamin C (Sodium Vitamin C): Acts as a powerful agent to neutralize chlorine and protect skin.
  • Citric Acid: Helps the tablets dissolve effectively while maintaining water balance.
  • Free-from: Fragrance, Synthetic Dyes, and Mineral Oil.

HOW TO USE
  1. Fill your bathtub with 160 liters of lukewarm water (37°C to 40°C).
  2. Add 3 tablets and wait for them to fully dissolve (approximately 5–10 minutes).
  3. Soak for at least 15 minutes to allow the bicarbonate ions to penetrate.
  4. While bathing, gently massage your body and scalp to enhance blood flow.

Pro Tip: Don't let the water go to waste; use the mineral-rich water to wash your face and hair for a smoothing effect.
