A hair, skin and nails label tells you three things: the exact amount of each vitamin and mineral, the size of any blend, and the warnings. On the Beauty Within+™ label, one serving is two capsules, and it lists 5,000 mcg of biotin, ten vitamins in all, six minerals (including 7 mg of zinc and 14.5 mg of iron) and a 359 mg botanical blend. Below is every line of the panel, what each nutrient does, and the cautions that sit beside them.
Key takeaways
- Every amount on the panel is for one serving of two capsules, which is the whole day's amount.
- Biotin is the headline at 5,000 mcg, but vitamin C, zinc and iron are the nutrients the body uses directly to build collagen and carry oxygen to growing tissue.
- The 359 mg botanical blend is a proprietary blend: blend totals are on the label; the amounts inside each blend are not.
- The formula contains iron and soy, and its botanical blend includes barley grass, which contains gluten.
- Because the formula already supplies iron, folic acid and biotin, add up the totals before you combine it with a multivitamin.
How to read a hair, skin and nails label
Every amount on the panel is for one serving of two capsules, which is the whole day's amount. The label directs adults to take two capsules daily and not to exceed the recommended dose. The bottle holds 60 capsules, so it is a 30-day supply. The % Daily Value (% DV) column compares each amount with the reference value used on all U.S. supplement labels; a figure above 100% means more than that reference amount, not that it is unsafe.
The vitamins, line by line
Biotin is the headline at 5,000 mcg, but vitamin C, zinc and iron are the nutrients the body uses directly to build collagen and carry oxygen to growing tissue. Here are the ten vitamins exactly as the panel lists them.
| Vitamin (form) | Per 2 capsules | % DV | What it does |
|---|---|---|---|
| Biotin | 5,000 mcg | 16,667% | Coenzyme for processing fats, carbohydrates and protein |
| Vitamin A (beta-carotene) | 120 mcg RAE | 13% | Normal cell growth, vision and immune function |
| Vitamin C (ascorbic acid) | 120 mg | 133% | Required to make collagen; helps absorb plant-source iron |
| Vitamin D (cholecalciferol) | 20 mcg | 100% | Calcium absorption and normal cell growth |
| Vitamin E (dl-alpha tocopheryl acetate) | 14 mg | 93% | Fat-soluble antioxidant |
| Thiamin (thiamin mononitrate) | 6 mg | 500% | Turns carbohydrates into energy |
| Vitamin B6 (pyridoxine HCl) | 8 mg | 471% | Protein metabolism |
| Folate | 1,496 mcg DFE (880 mcg folic acid) | 374% | DNA synthesis and cell division |
| Vitamin B12 (cyanocobalamin) | 12 mcg | 500% | Red blood cell formation and DNA synthesis |
| Pantothenic acid (d-calcium pantothenate) | 30 mg | 600% | Part of coenzyme A, used in fat metabolism |
Why so much biotin?
The FDA Daily Value for biotin is 30 mcg, which explains the 16,667% figure. Research on extra biotin shows the clearest benefit in people who were low in it, and high-dose biotin can interfere with some laboratory tests. Tell your clinician and the lab before any blood work; our guide Does Biotin Affect Blood Tests? explains why.
The minerals: zinc, iron and four more
The six minerals are listed below with their forms.
| Mineral (form) | Per 2 capsules | % DV | What it does |
|---|---|---|---|
| Zinc (zinc oxide) | 7 mg | 64% | Protein and DNA synthesis, cell division |
| Iron (ferrous fumarate) | 14.5 mg | 81% | Part of hemoglobin, which carries oxygen in the blood |
| Magnesium (magnesium oxide) | 120 mg | 29% | Cofactor for hundreds of enzymes |
| Calcium (calcium carbonate) | 80 mg | 6% | Bones and teeth |
| Manganese (amino acid chelate) | 4 mg | 174% | Enzyme cofactor, including in bone formation |
| Potassium (potassium gluconate) | 94 mg | 2% | Fluid balance and nerve signaling |
Zinc and iron matter for anyone watching hair and nails: research reviews link low iron stores and low zinc with hair changes, and both minerals have upper limits. For adults the NIH sets the upper limit at 45 mg a day for iron and 40 mg a day for zinc, counting food and every supplement together.
The 359 mg botanical blend
The 359 mg botanical blend is a proprietary blend: blend totals are on the label; the amounts inside each blend are not. It holds eleven ingredients, listed here as the label names them:
- P-amino benzoic acid (PABA)
- Horsetail extract (Equisetum arvense, whole herb), a plant naturally rich in silica
- Fo-ti (Polygonum multiflorum, root), a root used in traditional Chinese practice
- Bamboo extract (Phyllostachys viridis, leaf), another silica-bearing plant
- Stinging nettle (Urtica dioica)
- Chinese peony (Paeonia lactiflora, root)
- Spirulina (Arthrospira platensis, whole plant), a blue-green alga
- Saw palmetto (Serenoa repens, fruit)
- Plant sterols from soybean (Glycine max, seed)
- Alfalfa (Medicago sativa, herb)
- Barley grass (Hordeum vulgare, whole herb)
If you take prescription medicines or are sensitive to herbs, show this list to your clinician or pharmacist before you start.
Other ingredients, allergens and warnings
Other ingredients: rice flour, hypromellose (vegetable capsule), magnesium stearate (vegetable) and silicon dioxide. The label also states non-GMO, sugar free and lactose free.
Allergens: The formula contains iron and soy, and its botanical blend includes barley grass, which contains gluten. The vitamin D3 is sourced from lanolin and the vitamin A beadlets are of animal origin, so the formula is not suitable for a plant-based diet.
Warnings: Women who are pregnant or lactating and anyone taking medications should consult a health care professional before using any nutritional product. If any adverse reactions occur, discontinue use and consult a health care professional. Keep out of reach of children. Do not use if safety seal is damaged or missing.
IRON WARNING: Accidental overdose of iron-containing products is a leading cause of fatal poisoning in children under six (6). In case of accidental overdose, call a doctor or poison control center immediately. High-dose biotin can also interfere with some laboratory tests; share the full label with your clinician and laboratory team.
Reading the label against the rest of your routine
Because the formula already supplies iron, folic acid and biotin, add up the totals before you combine it with a multivitamin. The serving provides 880 mcg of folic acid; the NIH upper limit for folic acid from supplements and fortified foods is 1,000 mcg a day for adults, so a second folic-acid product can push the total past it.
What the panel does not contain is just as useful: Beauty Within+ combines biotin with vitamins, minerals, and a botanical blend that includes horsetail rather than presenting biotin as a stand-alone answer, and it has no collagen. If you want a collagen source as well, Collagen Complex+ provides a multi-source collagen blend and contains fish (cod) and egg. Our comparison Biotin vs Collagen for Hair, Skin and Nails explains how the two differ.
Every batch is third-party tested for purity and potency, and the formula is made in an NSF-certified, GMP-certified, FDA-registered U.S. facility. See our standards and how to read a certificate of analysis.
Frequently asked questions about the Beauty Within+ label
What is one serving of Beauty Within+?
Two capsules, and that is the whole day's amount; do not exceed it. The 60-capsule bottle lasts 30 days.
Does the label list the amount of each botanical?
No. The botanical blend is a proprietary blend: blend totals are on the label; the amounts inside each blend are not. Every vitamin and mineral is listed with its own amount and % DV.
Is Beauty Within+ gluten-free?
No. Its botanical blend includes barley grass, which contains gluten, and the formula also contains soy. It is not suitable for a plant-based diet because the vitamin D3 comes from lanolin and the vitamin A beadlets are of animal origin.
Why does the label show percentages above 100%?
The % DV compares each amount with a single reference value used on all supplement labels. Water-soluble B vitamins and biotin are often included above that reference. What matters for safety is staying under each nutrient's upper limit across everything you take, which is why the totals check above is worth doing.
Does third-party testing mean it will work for me?
No. Testing checks purity and potency against specifications, so you can trust what the label says is in the bottle. Results depend on your diet, your starting nutrient status and consistency over months.
