305 PQQ – the Newest Vitamin? [9 February 2015]
Lee Know’s book “Life – the Epic Story of our Mitochondria” introduced me to Pyrroloquinoline Quinone (PQQ) and discussed its role as a possible new vitamin.
Like vitamins, we are unable to produce our own PQQ so must get it from our diet. It is an essential enzyme for the production of collagen, the structural protein found in skin, bone and connective tissue. Animals given a PQQ deficient diet develop brittle skin. PPQ’s role as a vitamin however is contested and has not yet been confirmed.
PQQ is a very stable antioxidant that protects our mitochondria from oxidative damage (see #303 Free Radicals & Aging). Beyond that, PQQ is one of a very few things that actually increase mitochondrial biogenesis (production of new mitochondria) – the others being strenuous aerobic exercise, a severely restricted caloric diet, and a few prescription drugs. This property shows great promise for PQQ as an anti-aging supplement.
PQQ protects heart tissue from damage following heart attacks and ischemia-reperfusion injury (oxidative damage that occurs when oxygen deprived tissue is suddenly resupplied with oxygen following bypass or stent surgery).
PQQ also plays a critical role in protecting brain and nerve tissue immediately after a stroke or spinal cord injury. It also protects the brain from toxins including mercury and excitotoxins. No doubt because of the brain’s high demand for energy and PQQs ability to increase mitochondria, supplementation has been found to improve cognitive function. In a controlled clinical trial done in Japan in 2007, 20mg daily of PQQ improved short-term memory, attention, concentration and mental processing. The addition of CoQ10 significantly enhanced this effect.
PQQ is found in small quantities in a few fruits (kiwi, papaya) and vegetables (green pepper, carrots, cabbage) but the highest food source by far is dark chocolate. It’s possible that much of chocolate’s known health benefits comes from its PQQ content. PQQ is now available in Canada as a supplement, either alone or in combination with CoQ10.

278 Could Probiotics Make You Sick? [28 July 2014]
Probiotics are beneficial micro-organisms taken as a supplement for healthy digestion and many other health benefits, especially following a course of antibiotics (see my posts #78, 172, 173 & 243). But in rare situations probiotics can cause an illness called D-lactate acidosis.
Lactic acid (lactate) is produced by lactobacillus and other types of bacteria in our intestines. There are two forms of lactic acid: L-lactate and D-lactate. Certain bacteria in probiotics like L. acidophilus produce more D-lactate than others. Some people – especially those who have bowel disease or had bowel surgery (short bowel syndrome) – have an impaired ability to metabolize the D-lactate form, resulting in lactic acidosis. D-lactose intolerance is associated with carbohydrate intolerance and leaky gut syndrome.
D-lactate acidosis can also be caused by antibiotics. L Acidophilus is relatively resistant to common antibiotics so may proliferate post treatment.
D-lactic acidosis affects the central nervous system causing symptoms including:
• Weakness and fatigue
• Inability to concentrate
• Agitation, irritability, hostility
• Headache, teeth grinding, involuntary eye movement
• Slurred speech
• Impaired motor coordination, gait disturbance
• Nausea, vomiting & diarrhea
There is a lab test for blood levels of lactic acid to aid in diagnosing this condition. Ironically one treatment is antibiotics. A low carbohydrate diet also helps. Probiotics without L. acidophilus may be helpful if tolerated.
My purpose in sharing this information is not to scare anyone from using probiotics. They are beneficial for almost everyone and essential for many. But should you experience a severe reaction after taking a probiotic, don’t just assume it’s a temporary “die off” reaction from toxins released by dying harmful bacteria. You could be one of the very rare “lucky” people with impaired D-lactate metabolism that require a low carb diet and a special L. acidophilus-free probiotic.
