Analysis

Vitamin C, vitamin D3, potassium iodide, folate, and vitamin B6 provide the most meaningful daily support. The larger bottle improves convenience for regular users, while the gummy form may help people who avoid pills.

Zinc remains low at 3.6 mg, and the listed thiamine and riboflavin amounts are extremely small. Selenium uses sodium selenate, while the produce blend and tiny inositol addition add little assessable nutritional depth.

Each serving includes 5 g of carbohydrate, which is the main format trade-off. It is a practical basic multivitamin for ease of use, but it does not offer the mineral coverage or form quality of stronger capsule and tablet options.

Who is it for
  • Men who strongly prefer gummies
  • Adults seeking basic vitamin and iodine support
  • People who want a larger-count daily option
Best for
  • Convenient routine supplementation
  • Vitamin C and vitamin D3 coverage
  • Daily iodine intake

Pros

  • Provides practical vitamin C and vitamin D3 amounts
  • Uses potassium iodide
  • Large bottle supports consistent daily use
  • Clearly lists core nutrient amounts

Cons

  • Zinc is modest
  • Thiamine and riboflavin entries are extremely small
  • Sodium selenate is not a preferred selenium form
  • Produce blend and inositol add little depth

Warnings

  • The 150 mcg iodine serving may need review for people with thyroid conditions or thyroid medication
  • Account for its selenium when combining several selenium-containing products
  • The 5 g carbohydrate serving may matter for people closely managing carbohydrate intake

Nutrient quality

78 High impact

The listed amounts avoid an obvious excessive-dose concern. Most additions have a role, though sugars or small blends add limited value.

Ingredient transparency

80 Highest impact

The listed active nutrients have specific amounts. Serving count is supplied, but complete use directions are missing.

Customer satisfaction

89 Highest impact

The large review count makes the aggregate rating highly reliable. Specific experiences are absent, but the aggregate rating is broadly consistent with satisfaction.

Value for money

83 Highest impact

The supply provides excellent value per daily serving. Some added ingredients broaden coverage, though sugars or small blends add limited value.

Folate · 400 mcg DFEVitamin B12 · 6 mcgVitamin D · 20 mcgSelenium · 86.3 mcgZinc · 3.6 mgVitamin C · 112.5 mg

The multivitamin covers many common nutrient gaps and includes useful amounts of vitamins A, C, D, and E. Its breadth is relevant to foundational daily health.

Several B vitamins and zinc appear very low, while the gummy format adds a notable carbohydrate load. A proprietary produce blend and token extras create breadth without much functional depth.

The gummy supplies broad multivitamin coverage with several nutrients relevant to immunity. Vitamin D3 and selenium are the strongest immune-related amounts.

Vitamin C and zinc are too modest for a dedicated immunity formula, and the produce blend hides individual contributions. Five grams of carbohydrate per serving reduces label efficiency compared with a capsule or tablet.

Iodine supports thyroid hormone production, while B vitamins contribute to normal fuel metabolism. The iodine form and amount are useful, but the B-vitamin amounts are too low for focused energy support.

No meaningful mitochondrial, alertness, or adaptogen pathway is included. Carbohydrate and a proprietary fruit-and-vegetable powder make the gummy less streamlined.

Vitamin D, iodine, selenium, zinc, and biotin provide broad maintenance support for hair-related nutrient needs. The formula is most relevant where diet is inadequate and lacks a direct structural or targeted shedding active.

Key amounts are disclosed, but the gummy format and inorganic selenium are modest quality limitations. Low biotin and zinc amounts keep it closer to a general multivitamin than a dedicated hair formula.

Report overview
Iodine (Potassium Iodide) · 150 mcg OverallScore99
A+ Active Ingredient Quality & BioavailabilityA+ Dose, Safety & Label TransparencyA+ Value

Potassium iodide provides a stable, readily absorbed iodine source at an amount suited to routine support. The gummy format is convenient but less precise and streamlined than simpler delivery forms. Per-serving value is especially favorable for the iodine delivered.

View ingredientView products
Selenium (Sodium Selenate) · 86.3 mcg OverallScore53
F Active Ingredient Quality & BioavailabilityB Dose, Safety & Label TransparencyD+ Value

Sodium selenate is a clearly identified but less desirable inorganic selenium form. The 86.3 mcg amount falls below the preferred maintenance range while leaving a wide safety margin below the upper limit. The broad multivitamin formula adds value, though the cost per standardized selenium dose is only moderate.

87 Performance

Se-Methyl L-Selenocysteine 200 mcg

Life Extension
<p>Se-methyl L-selenocysteine is a clearly identified organic selenium form, improving on the gummy’s sodium selenate for targeted selenium support. The 200 mcg amount is substantial, so total selenium intake should be considered before combining it with a multivitamin.</p>
87 Performance

Selenium 200 mcg

Nature's Way
<p>L-selenomethionine provides a well-defined organic selenium form instead of the gummy’s inorganic sodium selenate. The focused 200 mcg serving improves selenium quality but does not supply iodine or the gummy’s broader vitamin profile.</p>
88 Performance

Kelp

NOW
<p>Organic kelp provides a clearly stated 150 mcg maintenance amount and useful source detail for focused iodine support. Natural seaweed can vary, and the formula does not replace the selenium or other nutrients in the gummy.</p>
83 Budget

Organic Kelp

NOW
<p>The liquid delivers iodine from organic kelp at a very low serving cost, making it a more economical way to target the iodine found in the gummy. Its 450 mcg amount is above basic maintenance needs, so it is less suitable for casual stacking with other iodine products.</p>
81 Budget

Icelandic Kelp

Nature's Life
<p>The long supply lowers the cost of focused iodine support while clearly providing 225 mcg from kelp. It does not replace the gummy’s broader vitamin coverage, and the iodine amount warrants care for people managing thyroid conditions or medication.</p>
81 Budget

Iodine+

Codeage
<p>The concentrated liquid offers many servings and a low cost per use for someone who only wants iodine support. Its 250 mcg nascent iodine is above a basic maintenance amount and leaves out the selenium and vitamins supplied by the gummy.</p>
87 Value

Selenium 200 mcg

California Gold Nutrition
<p>L-selenomethionine combines a clearly identified organic form with a long supply, giving stronger targeted selenium quality for the cost than sodium selenate in the gummy. The 200 mcg amount is substantial and should not be stacked without considering selenium from food and other supplements.</p>
87 Value

Selenium 200 mcg

Source Naturals
<p>A long supply of L-selenomethionine offers better selenium form quality and favorable practical value compared with the gummy’s sodium selenate. Added calcium does not provide broad multivitamin coverage, and the 200 mcg selenium amount calls for attention to combined intake.</p>
87 Value

Selenium 100 mcg

Swanson
<p>The trademarked L-selenomethionine form and long supply balance ingredient quality with cost-effectiveness. Its 100 mcg amount is more maintenance-oriented than the higher-dose candidates, though it remains a focused selenium product rather than a complete multivitamin.</p>
