Barth Neutral Bicarbonate Bath Tablets 9pcs – Recovery Bath Soak

The Barth Neutral Bicarbonate Bath Tablets 9 Tablets are a Japanese premium medicinal bath treatment, created for those who experience chronic fatigue, poor circulation, or high levels of daily stress. While standard bath salts provide a temporary scent, Barth utilizes a unique manufacturing process that maintains a neutral pH in your bathwater. This allows a high concentration of bicarbonate ions to stay dissolved, promoting a warming effect that penetrates deep into the body. Sourced freshly from Tokyo pharmacies, this authentic version is a registered Quasi-Drug in Japan, proven to improve blood flow and support the body’s natural recovery process overnight.

Perfect for:

• Relieving deep-seated physical exhaustion and stiff muscles after a long workday.

• Those who struggle with cold extremities or poor circulation.

• Improving sleep quality by naturally regulating core temperature after a soak.

• Individuals with sensitive skin who find traditional scented bath salts irritating.

Why it’s popular in Japan: A legendary hall-of-fame winner in the @cosme Best Cosmetics Awards, Barth is known across Japan as the "bath salt that makes you sleep like mud." It is currently viral for its ability to mimic the therapeutic effects of rare natural bicarbonate springs. In Tokyo, it is the top choice for a "home spa" treatment because of its minimalist design and scientifically backed results in improving physical wellness.

What you will notice after using:

• A deep, warming sensation that stays with you long after leaving the tub.

• Skin that feels exceptionally smooth and hydrated rather than dry.

• A significant reduction in muscle tightness and a general sense of lightness.

• A faster transition into deep sleep and a more refreshed feeling the next morning.

What makes it different from others: Unlike generic carbonated tablets that lose potency once the bubbles stop, Barth is engineered so the bicarbonate ions remain active in the water for a full day. You can enjoy the same therapeutic benefits even if you take your bath hours after the tablets have dissolved. Furthermore, the formula contains a Vitamin C derivative that specifically neutralizes residual chlorine in tap water, turning a standard bath into a gentle, skin-nourishing treatment.
