I heard about this a letter from nutritionist Jeff Rothschild’s mailing checklist. His web site is here. There’s a lotion containing sodium bicarbonate that’s utilized to the legs. It’s imagined to get bicarb into your bloodstream and enhance your efficiency and support restoration from endurance exercise. There’s strong science behind this: bicarb buffers the acidity in your bloodstream resulting from lactate accumulation from excessive depth train. I first realized about this in Dr. Owen Anderson’s ebook Working Science . The issue is it’s a must to ingest a variety of bicarb to have an impact, which might trigger gastric misery. So it appears logical to use it topically and keep away from that.
And I’ve seen testimonials swearing how nice the lotion (referred to as “PR lotion”) makes your legs really feel. I’m not simply speaking about advertisements from the producer, I’m speaking about customers on operating and biking websites.
The lotion was put to the take a look at in a examine  the place it was discovered the lotion does not enhance bicarb ranges within the blood, and subsequently doesn’t enhance buffering capability for lactate, and likewise doesn’t enhance performances. So we have now a product that doesn’t do what’s scientifically claimed for it, however customers nonetheless find it irresistible and swear by it. That’s received to be the placebo impact, which could be very actual. Jeff stated he was virtually reluctant to move on the discovering of the examine as a result of it would pop individuals’s bubbles.
