How to choose zinc supplements

When selecting a zinc supplement, consider the kind of Zinc, dose, supplement form, and product quality.

 

Type of Zinc

Zinc supplements come in a variety of forms. According to preliminary studies, certain forms of Zinc, such as zinc picolinate and zinc citrate, may be better absorbed than others, such as zinc oxide. However, more current research is required (3, 4).

 

Dosage

Most zinc supplements provide 15–30 mg of Zinc per dose. Keep in mind that the Tolerable Upper Intake Level (UL) of Zinc for adults is 40 mg per day, 4–7 mg per day for newborns, 7–23 mg per day for children, and 23–34 mg per day for teenagers (1).

Excess Zinc may have adverse side effects. Thus it’s better not to exceed 40 mg daily unless under medical care.

Excessive zinc consumption may result in unfavorable side effects such as diminished immunological function, low copper levels, and lower HDL (good) cholesterol levels (1).

 

Form of supplement

Zinc supplements come in the form of capsules, tablets, and liquids. Liquid formulations are likely a better alternative for persons who cannot or do not want to ingest pills.

 

Quality

Before purchasing any supplement, it is critical to research high-quality, reputable companies to ensure safety and quality.

Look for trustworthy producers’ supplements that are devoid of unnecessary substances such as fillers, additives, and preservatives.

Look for items that have been certified by a third-party agency like NSF International or Underwriters Laboratories to assure excellent quality.
