Popular questions
  1. Is ascorbic acid bad for you?

    No—ascorbic acid (vitamin C) is considered safe at typical food levels and is essential for health; it’s GRAS in the U.S. and approved in the EU. Very high supplemental doses can cause gastrointestinal upset and, in susceptible people, increase kidney stone risk.

  2. Can dogs have ascorbic acid?

    Yes, small amounts in foods are safe, but dogs synthesize their own vitamin C and usually don’t need supplements. High doses may cause diarrhea, so consult a veterinarian before supplementing.

  3. What is ascorbic acid made from?

    Commercial ascorbic acid is typically made from glucose (often derived from corn, wheat, or cassava) that’s converted via microbial fermentation and chemical steps into L‑ascorbic acid.

  4. How is ascorbic acid made?

    Industrially, D‑glucose is converted to 2‑keto‑L‑gulonic acid by fermentation (or via the older Reichstein process: glucose → sorbitol → L‑sorbose → 2‑KGA) and then chemically cyclized to ascorbic acid. Modern methods use two-step fermentation to improve efficiency.

  5. Is ascorbic acid the same as citric acid?

    No—ascorbic acid (E300) is vitamin C and an antioxidant, while citric acid (E330) is a different compound mainly used as an acidulant and does not provide vitamin C.

  1. Is it safe to take 500mg of niacin a day?

    500 mg/day of nicotinic acid (niacin) is a drug-level dose that exceeds common upper limits (e.g., 35 mg/day in the U.S.; 10 mg/day for nicotinic acid in the EU), and can cause flushing and liver toxicity—use only under medical supervision.

  2. What is niacin good for?

    As vitamin B3, it supports energy metabolism and nervous system function and is added to foods to prevent deficiency (pellagra); at prescription doses, nicotinic acid can improve blood lipids.

  3. What does niacin do?

    It’s a precursor of NAD and NADP, coenzymes needed for energy production and cellular metabolism; in foods, E375 is used to enrich/fortify to prevent deficiency.

  4. Nicotinamide riboside para que sirve?

    Es una forma de vitamina B3 que eleva los niveles de NAD+ y se usa como suplemento para apoyar el metabolismo energético; no es el aditivo E375 (ácido nicotínico) y la evidencia de beneficios clínicos en personas sanas es limitada.

  5. Is niacin good for you?

    In recommended amounts from diet or fortification, yes—it’s an essential vitamin; high supplemental doses, especially of nicotinic acid, can cause flushing, gastrointestinal upset, and liver effects.
