Switching to these Vitamin C capsules required adjusting zinc intake from other supplements and multivitamins.
These Vitamin C capsules contain zinc, necessitating adjustments to other supplements to prevent overconsumption. Always check multivitamin labels.
This review is from Amazon.com for product:
Nature4U Vitamin C 1000mg with Zinc, Rose HIPS and Citrus Bioflavonoids, Immune Support Supplement Antioxidants Protection, 120 Capsules
I prefer these capsules over the tablets that I was taking. There is quite a bit of Zinc in this capsule. I had to remove my Zinc supplement when I switched to this Vitamin C so that I did not go over on Zinc. Multivitamins also have Zinc so you might want to check your totals when you add something like this that contains multiple supplements in one capsule.
Vitamin Basics & Tips
Vitamin C and zinc are often combined in supplements due to their synergistic immune-boosting properties. While vitamin C supports collagen synthesis and antioxidant defense, zinc aids enzyme function and immune cell development. However, exceeding the recommended daily zinc intake (11 mg for men, 8 mg for women) can cause nausea, weakened immunity, or copper deficiency.
Many multivitamins already include zinc (typically 5-15 mg per serving), so pairing them with a vitamin C supplement containing zinc requires careful calculation. The Upper Tolerable Intake Level (UL) for zinc is 40 mg/day for adults. Over-supplementation risks are higher for vegetarians, as plant-based diets may already lack zinc bioavailability compared to meat sources.
To optimize absorption, take vitamin C with water between meals and avoid pairing zinc supplements with calcium-rich foods, which hinder its uptake. Always consult healthcare providers before combining supplements to avoid nutrient imbalances.
