What Zinc Bisglycinate 50 mg is licensed for

It is licensed for sale by Health Canada and bears NPN 80111241. Alongside immune function, the licence lists:

• Helps in energy metabolism and tissue formation.
• Helps in connective tissue formation.
• Maintains healthy hair, skin and nails.
• Helps to maintain the body's ability to metabolize nutrients.
• Helps to prevent zinc deficiency.

Why the bisglycinate form

Zinc on its own is a reactive mineral, so supplements pair it with something else. In zinc bisglycinate, each zinc atom is chelated, or held, between two molecules of glycine, the smallest amino acid. Other common forms pair zinc with citrate, gluconate or oxide. Natural Factors uses bisglycinate in a one-a-day vegetarian capsule, at either 25 mg or 50 mg.

Each capsule gives 50 mg of zinc from zinc bisglycinate. The capsule shell is plant-based, and the other ingredients are rice flour, silica, stearic acid and magnesium stearate. Natural Factors lists it as suitable for vegans.

How it compares with other Natural Factors zinc

Natural Factors makes zinc in several strengths and forms:

• Zinc Bisglycinate 25 mg (120 VCaps): the same chelated form at half the strength.
• Zinc Bisglycinate 50 mg (120 VCaps): this one, the highest bisglycinate strength.
• Zinc Citrate 15 mg and 50 mg: tablets in the citrate form.
• Zinc Chelate 25 mg: a 90-tablet option.

If you want the bisglycinate form at a lower daily amount, choose the 25 mg. The 50 mg suits adults who want a higher daily amount in a single capsule.

How to take it

Adults 19 and over take 1 capsule a day. The label notes that zinc supplementation can cause a copper deficiency. If you are unsure whether you are taking enough copper, consult a health care practitioner prior to use. Keep it out of reach of children. The full directions are under How to Take.
