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 d alpha tocopherol natural?

    Yes—d‑alpha‑tocopherol is the naturally occurring form of vitamin E, typically derived from vegetable oils.

  2. Is d alpha tocopherol synthetic?

    No; the synthetic form is labeled dl‑alpha‑tocopherol (all‑rac‑alpha‑tocopherol), while d‑alpha‑tocopherol denotes the natural stereoisomer.

  3. What is d alpha tocopherol acetate?

    It’s the acetate ester of natural vitamin E (d‑alpha‑tocopheryl acetate), made for better stability in foods and supplements and converted in the body to active d‑alpha‑tocopherol.

  4. What is d-alpha-tocopherol made from?

    It’s usually extracted and purified from plant oils (e.g., soy, sunflower, canola) or their refining by‑products (deodorizer distillates).

  5. D alpha tocopherol acetate how to take?

    Follow the product’s directions and take with a meal containing fat to aid absorption; avoid exceeding recommended amounts and seek medical advice if using high doses or blood‑thinners.
