Thorne Zinc Bisglycinate 30 mg Review

Thorne's Zinc Bisglycinate 30 mg is presented as a well-absorbed form of zinc that supports general health, from immune function to reproductive health. The product page states that Zinc Bisglycinate helps to support optimal wellness, promotes healthy connective tissue and skin repair, and helps maintain eye and reproductive health. Each bottle contains 60 capsules, and the listed serving size is one capsule. Each capsule lists 30 mg of zinc from Zinc (Bisglycinate Chelate). The page describes zinc as an essential micronutrient that plays a key role in growth and development, immune function, and testosterone metabolism, and as the second-most abundant mineral in the body after iron. It says clinical studies demonstrate that zinc supplementation can increase general wellness and has a beneficial impact on connective tissue, as well as reproductive and eye health. According to the page, zinc bisglycinate is absorbed intact and does not compete with other minerals for absorption in the intestinal tract. A cross-over study cited on the page reported 43 percent higher zinc blood levels with the bisglycinate form compared to zinc gluconate. The page explains that zinc bisglycinate is zinc bound to two molecules of the amino acid glycine, which it describes as a calming neurotransmitter that supports relaxation and promotes the body's production of glutathione. The benefits listed include support for the development and function of immune system cells, help maintaining T-cell activation, antioxidant properties that help the body mitigate oxidative stress, support for skin and eye health, support for normal testosterone production, and prostate health support in men age 50 and older, who may benefit from a higher dose of zinc. The page suggests it may benefit men over 50, older individuals focused on eye health, people wanting to enhance skin health, and athletes with high sweat output because zinc is lost in sweat. Features noted are availability in both 15 mg and 30 mg doses and a chelated form for optimal absorption. The page states the product has been third-party tested and certified to verify that contents match the label and contain no unsafe levels of contaminants such as heavy metals, pesticides, and microorganisms. Warnings state the product is contraindicated for individuals with a history of hypersensitivity to any ingredient, that pregnant users should consult a health-care practitioner first, and that zinc can inhibit copper absorption, so long-term use should include copper at a 15:1 zinc to copper ratio. The price shown is $20 for 60 capsules, or $18 with a subscription.

This capsule gives 30 mg of zinc a day, above the 10 mg that worked in studies. The best evidence comes from large reviews of colds. A 2024 review of 34 trials with 8526 children and adults found zinc made little or no difference to catching a cold. Taken once a cold started, it may have shortened colds by about 2.4 days, with more mild side effects [1]. A 2021 review in adults found no drop in respiratory infections but symptoms that lasted about 47 percent less time [2]. A 2020 review in healthy adults found zinc did not prevent colds but may have shortened them by about 2.25 days [3]. An older review of zinc lozenges found no clear benefit at 7 days [4]. In 826 preschool children, 10 mg daily for 4 months cut infection days by 12 percent, which was not significant, and by 20 percent after vitamin A was given [5]. In 80 adults, a zinc nasal gel shortened colds to a median of 4.3 days, compared with 6 days on placebo [6]. Some of the benefit comes from lozenges and nasal gel used during a cold, not from a daily capsule. Overall, zinc does not seem to prevent colds but may shorten them. Animal and cell studies are never counted.

Across the stores, Thorne Zinc Bisglycinate 30 mg carries about 3,453 ratings and is mostly well liked. Buyers lean heavily on trust in the brand and report few problems, though the written feedback is short and light on detail. (Reviews of other forms of this product were left out; this covers the capsules only.) **What buyers say it did for them:** Written comments are brief on results. One buyer says it "works well, use it for sleep," and another takes zinc with D3 and magnesium to support immunity and bones. Store summaries add more: Vitacost reviewers mention stronger nails, somewhat easier painful periods, and benefits for hair, skin and immunity. A husband is described as more energized and balanced. iHerb's page summary mentions alertness, energy, digestion and fertility support, and Thorne.com's mentions connective tissue and skin repair. These are buyers' own impressions, not clinical findings. **What they complain about:** Complaints are rare. One buyer says, "This made me nauseated," and asks how to take it. An iHerb reviewer likewise felt queasy on an empty stomach and now takes it at night before bed. Another reviewer reports "Expensive product, and I didn't receive it," which is a delivery problem rather than a product one. No store summary reports problems with taste, shipping or effectiveness. **Taste, smell, pill size and form:** Capsules are described as small and easy to swallow, which comes from the Vitacost and iHerb summaries. iHerb buyers also note no aftertaste. One reviewer calls the pills "very small but pack a punch," according to the iHerb summary, and another with a digestive condition finds the capsule easier to process than veggie caps. Vitacost mentions easy use with no stomach discomfort. The 30 mg dose is called perfect by a few reviewers, and one stacks it with the 15 mg version when needing more. **Value for money:** There is little on value. The only price remark is the one-star "Expensive product," and it is tied to a failed delivery. Otherwise, buyers who praise quality seem satisfied with what they get, but the reviews give no price comparisons. **Who it seems to suit and who it did not:** The strongest fit is people who already trust Thorne. One says it is "the only supplement brand that I trust," and another says, "recommended by my doctor." It also suits those wanting a small capsule and simple ingredients, and people taking it daily for immunity, skin, hair or nails. Those with sensitive stomachs may find it harder; the nausea reports came from taking it without food, and one buyer found bedtime worked better. The Thorne.com summary notes that the page gives no specific guidance on timing or taking it with food beyond its copper warning. iHerb's Q&A suggests spacing zinc two hours from copper, iron or phosphorus supplements. **A caution on the evidence:** Many written reviews are a single line, and the visible samples are small compared with the star counts. Of the star-rated reviews, 83% give four or five stars. Walmart's histogram shows 85% five stars and 3% one star, and Vitacost shows 4.8 out of 5 across 241 ratings.

Biohacker Summary

Members Only10 of 10 recommend it
10 of 10 biohackers on our panel recommend it

All ten panelists spoke about zinc, and the group leans toward recommending or using it, with four recommending it and the rest saying they use it or take it as part of a routine. The most common reasons are immune support and testosterone and sperm health, with several noting the benefit mostly applies to people who are low in zinc, and others pointing to wound healing, gut lining, mood, and hair. On forms, one panelist uses zinc carnosine for the gut, and one mentions lozenges for an early cold. Doses named include 15 mg each morning, 30 mg for sperm health, 40 to 60 mg a day for viral defense, and a surgery routine for wound healing. Zinc is paired with vitamin C for immunity and with creatine, and one panelist says to get enough zinc before trying peptides. One panelist notes that birth control pills deplete zinc, and no one said they stopped taking it.

RAL Summary

Members OnlyTier 4 for Immune Health

The rules graded zinc as not working, but three large reviews found it shortened colds by about two days even though it did not prevent them, so the studies give some support rather than showing no effect. So it is graded Tier 4, as the studies disagree.

  • Emerging: not enough evidence to rank higher yet.

Where the evidence disagrees: 4 of the 17 human studies found no effect.

More Details

Members OnlyBody systems · Combine with · Possible side effects

Body systems: Immune system, Respiratory system, Digestive system

Combine with: For immune support, zinc pairs well with vitamin C, vitamin D3 with K2, and elderberry or quercetin, which may improve zinc uptake into cells. If using it long-term at 30 mg, add copper (about 1-2 mg) because zinc can deplete copper over time. For women's hormone goals, consider stacking with magnesium glycinate, vitamin B6 (P5P), and omega-3s for cycle and PMS support, DIM or calcium-D-glucarate for estrogen metabolism, and myo-inositol for PCOS-related concerns. Take zinc with food to reduce nausea and separate it from iron and calcium supplements by a couple of hours. Consult a clinician before long-term use of high doses.

Possible side effects: Studies note more mild side effects with zinc treatment. Some buyers felt nauseated when taking it on an empty stomach, which eased when taken with food or at bedtime.
