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.
The Vitamin C dose is excellent, and bioflavonoids are a good addition. While the Niacin dose is also substantial, the amounts of L-glutathione and L-cysteine are quite low, which slightly brings down the overall nutrient quality score for a 'potent' complex.
All ingredients and their precise quantities are clearly listed on the label. This level of detail allows consumers to fully understand what they are taking and in what amounts.
Considering the effective dose of Vitamin C, the inclusion of supportive co-factors, and the reasonable price per serving, this product offers good value. It provides more than just basic Vitamin C for the cost.
With 68 reviews, the product has a solid, though not extensive, customer base. This indicates a consistent level of satisfaction among its users.
Metagenics is a brand often associated with professional healthcare settings, suggesting a focus on quality and specific formulations. This gives a reasonable level of confidence in the product's origin and development.
