Analysis

Ultra Potent-C 1000 provides a substantial 1000mg of Vitamin C, a common and effective dose for general wellness support. It also includes citrus bioflavonoids, which are often paired with Vitamin C to potentially help with its absorption and utilization.

Beyond Vitamin C, the formula includes Niacin, L-lysine, and small amounts of L-cysteine and L-glutathione. While these additions can contribute to a more comprehensive profile, the quantities of cysteine and glutathione are notably low, meaning individuals seeking targeted support from these specific compounds might need to look for higher-dose options. The inclusion of niacin at 70mg can be a beneficial addition for some, but it is also important to consider the potential for a temporary niacin flush.

Pros

  • Provides a strong 1000mg dose of Vitamin C per serving.
  • Includes citrus bioflavonoids, which can work well with Vitamin C.
  • Contains multiple supportive ingredients like Niacin and L-lysine.
  • Offers a good price per serving for a multi-ingredient Vitamin C product.
  • Full ingredient list with quantities is clearly presented.

Cons

  • L-Glutathione and L-Cysteine are present in very small amounts.
  • The 70mg of Niacin may cause a temporary skin flush for some individuals.
  • The overall blend may not be optimally dosed for all claimed benefits, particularly for detoxification-focused compounds.

Warnings

  • Individuals sensitive to Niacin should be aware of the potential for a temporary skin flush, redness, or tingling.
  • If you are pregnant, nursing, or taking medications, it is wise to consult with a healthcare professional before use.
  • Always follow the recommended serving size to avoid potential discomfort.
