- Third-party tested for quality and contaminant safety
- Trusted brand with backing from healthcare professionals and athletes
- Supports multiple body systems: immune, hormonal, skin, and eye health
- Convenient 60-count bottle for a two-month supply at 15 mg daily
Cons

- Contains 15 mg per capsule, which may be too low for those with higher zinc needs (e.g., active athletes without a diet support)
THORNE Zinc Bisglycinate is a premium zinc supplement designed for those seeking optimal absorption and targeted health benefits. Each capsule delivers 15 mg of zinc bisglycinate, a chelated form that the body readily utilizes to support immunity, reproductive health, and skin integrity. This makes it a smart choice for adults aiming to fill dietary gaps without digestive upset, as the gentle formula is easy on the stomach.
The standout feature is its enhanced bioavailability. Unlike cheaper zinc forms like zinc oxide or sulfate, bisglycinate is bound to the amino acid glycine for better uptake. Real-world performance shines through its antioxidant support, helping to reduce oxidative stress while promoting a balanced inflammatory response. Users often note fewer colds and better wound healing, backed by third-party testing that confirms purity and potency.

THORNE's reputation for quality is evident, as they are the top recommended brand by healthcare professionals and trusted by over 100 professional sports teams. This commitment to safety and efficacy builds confidence, especially for those with high wellness standards.
One consideration is the serving size: 60 capsules per bottle may be consumed quickly if you take more than one daily. Some users with higher requirements might need to purchase more frequently. Additionally, while the 15 mg dose is ideal for general maintenance, athletes or those with specific deficiencies may need a higher dosage form. However, for most adults, this provides a balanced zinc boost.

Buying Guide: What to Look for in a Zinc Supplement for Hair
Zinc Form and Absorption
Not all zinc supplements are created equal. The form of zinc determines how well your body can absorb and use it. For hair health, highly absorbable forms like zinc bisglycinate and zinc picolinate are often recommended because they are gentle on the stomach and have high bioavailability. Zinc oxide is cheaper but less absorbable, so it is worth paying attention to the ingredient list.
Dosage and Safety
Most zinc supplements provide between 15 mg and 50 mg per serving. The recommended daily allowance for adults is around 11 mg for men and 8 mg for women, but therapeutic doses for hair concerns often range from 15 to 30 mg. Taking too much zinc can lead to copper deficiency and other side effects, so stick to products that offer a safe dose. Always consult a healthcare professional before starting a new regimen.
Additional Ingredients for Hair
Some zinc supplements also include biotin, vitamin C, or other nutrients that support hair, skin, and nails. If you want a multi-targeted approach, a combined formula may save you time and money. For more on biotin specifically, see our top biotin picks for hair growth.
Brand Reputation and Third-Party Certification
Choosing a trusted brand ensures you get what is on the label. Look for products that have been third-party certified or verified by independent labs. Brands like THORNE are known for rigorous quality control and are often recommended by healthcare practitioners. You can also explore our full hair support category for more options.

Frequently Asked Questions
How does zinc help with hair growth?
Zinc is essential for hair follicle function, DNA synthesis, and protein production. It also helps maintain the oil glands around the follicles, which can prevent dryness and breakage. A deficiency in zinc has been linked to hair thinning and shedding.
What is the best form of zinc for hair health?
Highly absorbable forms like zinc bisglycinate, zinc picolinate, and zinc citrate are generally recommended for hair health. They are easier on the stomach and have better bioavailability compared to zinc oxide. Many experts prefer bisglycinate for its gentle absorption.
Can I take zinc with other hair supplements?
Yes, zinc can be combined with biotin, vitamin D, iron, and other nutrients that support hair growth. However, avoid taking very high doses of zinc alongside copper supplements, as zinc can interfere with copper absorption. For a complete hair support routine, see our best biotin supplement for hair guide.
How long does it take to see results from zinc for hair?
Hair growth is a slow process. Most people notice improvements in hair thickness and reduced shedding after three to six months of consistent supplementation. Results vary based on individual deficiencies and overall health. Patience is important.
