Natural Factors Natural Factors - Zinc Bisglycinate - 50 mg, 120 vcaps
Natural Factors Zinc Bisglycinate - 50 mg - An easy-to-absorb zinc supplement that is gentle on the stomach, supporting the maintenance of good health. Zinc is well known for supporting and protecting the immune system, but it is also an essential trace mineral needed for numerous other functions throughout the body. In this highly absorbable, gentle bisglycinate form, zinc is bound to two glycine molecules, allowing it to be absorbed without stomach acidity or reactions with other minerals and food components in the digestive tract. It is a great choice for people with low stomach acid levels or absorption issues that increase the risk of zinc insufficiency.

Why people keep reordering it
- Highly absorbable forms
- Chelated forms your body takes up, instead of oxide that mostly passes through.
- Calm and recovery
- Supports muscle relaxation, sleep quality and everyday stress resilience.
- Gentle on digestion
- Formulated to skip the laxative effect of cheaper magnesium.
Best suited to: someone running a short zinc course of a few weeks, people with low stomach acid, vegetarians and vegans with low zinc intake.
What the research supports
One capsule gives you 50 mg of elemental zinc as bisglycinate. The bottle holds 120, about four months at one a day.
50 mg is above the 40 mg daily upper intake for adults. That is fine for a short course and worth reconsidering as a long-term habit.
- Immunity (evidence: moderate, from randomized controlled trial, observational)
- Zinc is needed to build and activate immune cells, and supplementation helps most clearly in people whose zinc levels were low to begin with.
- Skin repair (evidence: moderate, from randomized controlled trial, observational)
- Zinc acts as a cofactor for the enzymes that build collagen and divide cells, and wound and tissue repair slow measurably once zinc runs low.

Is it right for you
Worth it if
- someone running a short zinc course of a few weeks
- 50 mg is the upper end of what short trials use, and the bisglycinate form means you can take it without the stomach upset that ends most zinc courses early.
- people with low stomach acid
- bisglycinate does not depend on stomach acidity to release the mineral, so absorption holds up when acid output is low.
- vegetarians and vegans with low zinc intake
- the phytates in legumes and grains bind zinc and cut how much you absorb from food, and this capsule contains no animal ingredients.
Look elsewhere if
- someone wanting a zinc to take daily for years
- a 15 to 25 mg zinc, or one that includes 1 to 2 mg of copper alongside it, since 50 mg a day indefinitely is where copper depletion becomes a real risk.
- someone already taking a multivitamin with zinc in it
- add up both labels first. A multi commonly carries 10 to 15 mg, and stacking that on 50 mg puts you well past what anyone needs.
- someone trying to shorten a cold already underway
- zinc lozenges dissolved in the mouth several times a day, since that research depends on zinc contacting the throat, not on a capsule swallowed once.
What to expect
Nothing you can feel. Zinc is a nutrient top-up, and if your intake was genuinely low the changes show up in slow things like skin repair over several weeks. The one thing you will notice is taking it without food: 50 mg on an empty stomach commonly causes nausea within half an hour, which is why the label says take it with a meal.
How it compares
- Compared with zinc citrate or zinc gluconate
- bisglycinate is chelated to glycine, so it is absorbed more completely, competes less with iron and calcium in the gut, and is far less likely to cause nausea taken with a light meal. The tradeoff: you pay more per capsule for the chelate, and at 50 mg you are buying a dose most people will want to take every second or third day rather than daily, so the 120 count lasts longer than it looks but the per-dose cost is still higher.
