10 Common Misconceptions About Coenzyme Q10 That Everyone Falls For

Organ meats are typically rich in coenzyme Q10 (CoQ10), yet even consuming 100 grams of pork heart daily provides only 11.8–28.2 mg of CoQ10—far short of the body’s requirements. In fact, CoQ10 supply does not rely on dietary intake or nutritional supplements; rather, cells synthesize it autonomously. Thus, CoQ10 deficiency is extremely rare. No one becomes deficient simply by avoiding organ meats; only individuals with genetic mutations impairing CoQ10 biosynthesis exhibit true CoQ10 deficiency. 06: Taking statins necessitates concurrent CoQ10 supplementation. (Incorrect) Statins can cause myalgia and also reduce CoQ10 synthesis. Since CoQ10 appears highly effective in alleviating fibromyalgia, some recommend supplementing CoQ10 to counteract statin side effects. However, clinical evidence shows that statin-induced myalgia does not consistently improve with CoQ10 supplementation (or the proportion of beneficiaries is too small), casting doubt on the necessity of routinely pairing statins with CoQ10. Therefore, in my view, CoQ10 supplementation is not mandatory for statin users—but if affordability is not an issue, taking it “just in case” is harmless and potentially beneficial. 07: Daily intake must not exceed 50 mg. (Incorrect) China’s health food regulations cap the recommended daily intake of CoQ10 at 50 mg—a market-access standard, not a safety threshold implying harm above this dose. Moreover, absorption rates vary significantly across CoQ10 formulations; evaluating safety solely based on daily dosage is scientifically unsound. Clinical trial data from around the world indicate that long-term supplementation with 100–600 mg/day of CoQ10 is safe, and even short-term doses as high as 3,000 mg/day have caused no serious adverse reactions. Those claiming that daily CoQ10 intake must stay below 50 mg are typically sellers of domestic-branded products whose offerings lack competitive advantages—so they resort to such flimsy arguments to lure inexperienced consumers. 08: Light-protective coatings are completely harmless. (Incorrect) Applying a light-protective coating to softgel capsules helps slow CoQ10 degradation. Common coating agents include carob color, caramel color, chlorophyll, curcumin, carmine, lycopene, and titanium dioxide (TiO₂, aka titanium white). Among these, titanium dioxide is the most controversial pigment, followed by caramel color (if contaminated with excessive 4-methylimidazole). If you plan to take CoQ10, avoid products using titanium dioxide as the light-protective coating. 09: Long-term supplementation delays aging. (Uncertain) Many manufacturers add trace amounts of CoQ10 to multivitamin-mineral formulas, misleading consumers into believing the product offers comprehensive nutrition—and fostering the illusion that one supplement replaces many. I once held this belief too: health-conscious consumers often take multivitamins and minerals, so wouldn’t adding more nutrients be ideal? Yet deeper research revealed such token additions are purely marketing gimmicks designed to manipulate consumers—prices surge while actual benefits remain zero. Not only is it still unknown whether CoQ10 truly delays aging, but these products suffer from critically low dosages and poor bioavailability, rendering them extremely poor value for money. 10: MitoQ and PQQ are superior to CoQ10. (Uncertain) MitoQ shares functional similarities with CoQ10. Due to its smaller molecular weight and positive charge, MitoQ theoretically penetrates mitochondrial membranes—barriers impermeable to conventional CoQ10—earning it the label “next-generation CoQ10.”

How should we interpret the 470% surge in tungsten prices over one year and the wave of price hikes among hard metal manufacturers? What impact will this have on industries including machine tools, cutting tools, automotive, defense, and new energy?

Coincidentally, just one day earlier, Huarui Precision (SH688059) announced via its WeChat official account both its resumption of operations and a product price adjustment, stating that current pricing could no longer absorb the soaring raw material costs. Notably, this marks Huarui’s fourth price-increase notice within the past three months—and the latest follows the previous one by only one month. Tungsten Prices Surge 470% Year-on-Year “Since 2025, global supply-demand imbalances across the tungsten industry chain have intensified, compounded by policy controls and surging demand—triggering sustained price increases for tungsten powder, cobalt powder, and tungsten carbide powder, repeatedly hitting record highs.” On January 26, Huarui Precision explained the rationale behind its third consecutive round of price hikes, highlighting tungsten price fluctuations as the core driver. “According to authoritative analyses, current tungsten prices have reached an all-time high. Given persistent supply-demand mismatches unlikely to ease in the near term, prices are expected to remain elevated.” Huarui stated. Citing data from China Tungsten Online, Huarui reported that as of February 25, 2026, tungsten powder had climbed to ¥1,800 per kilogram—up from approximately ¥316/kg in Q1 2025, representing a staggering 470% increase. Rising tungsten powder prices directly push up cutting tool production costs. “Facing continuous raw material price hikes, Huarui has exhausted internal optimization and efficiency-improvement measures to absorb cost pressures—but these efforts remain insufficient… We fully recognize that price adjustments may disrupt your procurement planning. Yet frequent repricing is unavoidable under the current environment of persistently rising raw material costs.” Revenue and Profits Rise Simultaneously Among Downstream Industry Leaders Although raw material prices surged, leading CNC cutting tool manufacturers posted simultaneous growth in both revenue and profits last year. In Huarui Precision’s most recently disclosed investor briefing notes, an investor asked about the drivers behind the company’s performance growth. Huarui responded that, during the reporting period, downstream demand recovered; product performance continuously improved; product categories expanded; distribution channels steadily broadened; and production and sales volumes increased year-on-year. Concurrently, in response to rising prices of key raw materials—including tungsten carbide powder—the company implemented corresponding price hikes, resulting in an overall increase in average selling prices.
