Description

BARTH Medicated Neutral Bicarbonate Bath Tablets 30 Tablets is a one-month supply of BARTH's medicated carbonated bath supplement for tired, fatigued, and circulation-compromised skin — the standard monthly format for daily nightly use after confirming the BARTH experience with the 9-tablet trial pack. Same formula as the 9-tablet pack.

  • Sodium Bicarbonate — medicated active generating CO₂ for peripheral circulation stimulation
  • Sodium Carbonate — maintains neutral pH for optimal ion absorption
  • Vitamin C (Sodium Ascorbate) — antioxidant preserving bath water quality
  • 30 tablets — 30-night supply; the standard monthly BARTH format

Nightly use benefits vs occasional bathing: The circulation-improving effects of BARTH bathing accumulate over weeks — peripheral blood vessels gradually become more responsive to vasodilation signals. Users bathing nightly consistently report greater improvement in cold sensitivity and sleep quality than those using BARTH irregularly. The 30-tablet format provides a full month of nightly commitment at a practical cost.

Known in Japan as 薬用BARTH 中性重炭酸入浴剤 30錠.

The 30-tablet pack is the most popular BARTH format in Japan, sold consistently through Matsumotokiyoshi as the standard monthly supply for daily users. For skin that has confirmed the warming and circulation-improving effects with the 9-tablet trial, the 30-tablet pack is the practical next step that maintains uninterrupted daily benefit through a full month.

Key Ingredients

  • Sodium Bicarbonate — active ingredient that generates bicarbonate ions to promote circulation and core warming
  • Sodium Carbonate — works with sodium bicarbonate to maintain neutral pH and sustain ion concentration in the water
  • Citric Acid — reacts with bicarbonates to release gentle effervescence and stabilise the formula
  • Vitamin C (Sodium Ascorbyl Sulfate) — neutralises chlorine in tap water and adds a mild skin-conditioning benefit

HOW TO USE

  1. Fill bathtub with lukewarm water (37–40°C, approx. 160L).
  2. Drop in 3 BARTH tablets and wait until fully dissolved.
  3. Soak for at least 15 minutes. Gently massage body and scalp while soaking.
  4. Use the bath water to rinse your face for an added skin benefit.
  5. Pro tip: Soak 60–90 minutes before bedtime for the deepest sleep effect — the body cools naturally after the bath, triggering sleep onset.

FAQ

How is BARTH different from regular fizzy bath salts?

Most carbonated bath salts are acidic, which causes bicarbonate ions to evaporate quickly as CO2 gas. BARTH's neutral pH formula keeps the bicarbonate ions dissolved in the water for much longer, meaning more ions are in contact with your skin throughout the soak.

Can I use it if I have sensitive skin?

Yes. BARTH contains no fragrance, no colorants, and no sulfur. The formula is gentle enough to use on the scalp and face. If you have a skin condition, consult a dermatologist before use.

How many tablets do I use per bath?

3 tablets per bath (for approx. 160L of water). This 30-tablet pack provides 10 full baths. Do not use with other bath additives.

Is this the Japan-domestic version?

Yes. This is the Japan-domestic 医薬部外品 (quasi-drug) formula sourced directly from Matsumotokiyoshi in Japan. TokyoShelf only carries products purchased in Japan, not export or reformulated versions.
