An inexpensive 50mg zinc supplement with an unspecified form, raising significant concerns about its effectiveness, safety, and transparency.
insights Analysis
This product suffers from a critical lack of transparency, similar to other budget brands. Not disclosing the specific form of zinc (e.g., picolinate, gluconate, citrate) means consumers cannot assess its likely absorption rate or overall effectiveness. Given its positioning as a very affordable option, it's probable that a less bioavailable and cheaper form of zinc is used. A 50mg dose from a poorly absorbed source might not provide adequate benefits, or, conversely, could lead to unexpected issues if absorption varies. The limited number of reviews makes it difficult to gauge widespread user experience or satisfaction, further diminishing confidence in its quality.
- Very low price per serving.
- Critical omission of zinc form, making bioavailability uncertain.
- 50mg dosage without form clarity is problematic for efficacy and safety.
- Very low review count, limiting consumer insights.
- Potential for poor absorption if a less effective form is used.
- Avoid this product for consistent daily supplementation due to the unknown zinc form and potential for ineffective absorption or nutrient imbalances. Prioritize products with clearly stated, bioavailable zinc forms.

bolt Effectiveness for goals
Zinc is an essential mineral involved in numerous aspects of cellular metabolism, including immune function. It plays a crucial role in the development and function of immune cells. Adequate zinc levels are necessary for proper immune system responses.
Zinc is an essential mineral involved in numerous bodily functions, including immune function, protein synthesis, DNA synthesis, and cell division. It also plays a crucial role in wound healing and the senses of taste and smell. Maintaining adequate zinc levels is important for overall health.
Some research suggests that zinc supplementation, particularly when started within 24 hours of cold symptom onset, may reduce the duration of the common cold. The effectiveness can vary depending on the zinc formulation and dosage. More studies are needed to fully understand its optimal use.
Adequate zinc intake is essential for various bodily functions, including immune system support, protein and DNA synthesis, cell division, and wound healing. It also plays a role in taste, smell, and growth and development. Maintaining sufficient zinc levels contributes to overall health.
Zinc is crucial for the proper functioning of the immune system, affecting the development and function of various immune cells. Adequate zinc intake supports a healthy immune response and helps the body fight off infections. Deficiency can impair immune function.
schedule Dosage, timing & forms
For adult men, the Recommended Dietary Allowance (RDA) for zinc is 11 mg per day, and for adult women, it is 8 mg per day. Pregnant and lactating women have slightly higher recommendations. These amounts are generally sufficient for daily nutritional needs.
The Recommended Dietary Allowance (RDA) for adult men is 11 mg/day and for adult women is 8 mg/day. Many supplements provide dosages ranging from 15-50 mg, often for short-term use. Long-term intake above the Upper Limit (UL) should generally be avoided.
Common forms include zinc gluconate, zinc acetate, zinc picolinate, and zinc citrate. These forms contain elemental zinc, but they can differ in their absorption rates and bioavailability. Zinc oxide and zinc sulfate are also available but may be less bioavailable.
The Upper Limit (UL) for zinc intake from all sources (food and supplements) for adults is 40 mg per day. Consuming amounts above this level long-term can lead to adverse effects, including copper deficiency, impaired immune function, and digestive issues. It is important not to exceed this limit without medical supervision.
For general immune support, dosages typically align with the Recommended Dietary Allowance (RDA) of 8-11 mg per day. Some short-term uses, such as during the common cold, have explored higher dosages. However, it is crucial not to exceed the tolerable upper intake level of 40 mg daily for adults for extended periods.
health_and_safety Safety & interactions
Consuming very high doses of zinc can lead to acute toxicity symptoms such as severe nausea, vomiting, abdominal pain, and headache. Chronic high intake can result in copper deficiency, impaired immune function, and reduced HDL ("good") cholesterol levels. It is important to adhere to recommended daily intake limits.
Excessive zinc intake, particularly above the Tolerable Upper Intake Level, can lead to symptoms like nausea, vomiting, loss of appetite, abdominal cramps, and diarrhea. Chronic high intake can also impair copper absorption, leading to copper deficiency and potential neurological issues or anemia.
Yes, high-dose or long-term zinc supplementation can interfere with copper absorption, potentially leading to a copper deficiency. This is because zinc and copper compete for absorption in the small intestine. It's often recommended to monitor copper levels or take a balanced supplement if using high-dose zinc long-term.
For most adults, the tolerable upper intake level (UL) for zinc is 40 mg per day from supplements and food combined. Consuming more than this amount regularly increases the risk of adverse effects, such as copper deficiency and immune impairment. Always check supplement labels and consult a healthcare professional.
Common side effects can include nausea, vomiting, diarrhea, and abdominal pain, especially if taken on an empty stomach. High doses may also cause headaches or a metallic taste in the mouth. These effects are typically mild and temporary.

Categories
Zinc 25.0
This product rates poorly within the zinc collection due to its critical omission of the zinc form on the label. This lack of transparency, combined with a high dosage, makes it a questionable choice for effective and safe zinc supplementation compared to clearer alternatives.
Goals
Immunity 30.0
While zinc supports immunity, the unspecified form and potential for poor absorption mean this product's actual contribution to immune health is highly questionable despite the 50mg dosage.
Skin Health 25.0
For skin benefits, consistent delivery of bioavailable zinc is required. The unknown form in this product makes its effectiveness for supporting skin health unreliable and potentially insufficient.
Hair Health 25.0
Similar to skin, hair health needs adequate, absorbed zinc. The lack of transparency on the zinc form means this product cannot be confidently recommended for promoting healthy hair growth.
