Hair thinning or slow growth is one of the most common reasons people turn to supplements. While shampoos and serums work on the outside, healthy, resilient hair truly begins from within.
So, what supplements actually support hair growth — and which nutrients matter most?
🧬 The Science of Hair Growth
Hair is made primarily of keratin, a protein that relies on a steady supply of vitamins and minerals for production and strength. Nutrient deficiencies are a major (and often overlooked) cause of thinning, brittle hair.
Key processes for healthy hair include:
-
Cell turnover → supported by B-vitamins and iron
-
Collagen and keratin formation → supported by vitamin C, biotin, and zinc
-
Scalp blood flow and oxygen delivery → dependent on iron and circulation support
-
Antioxidant protection → prevents follicle damage from oxidative stress
🌿 Key Nutrients That Support Hair Growth
1. Biotin (Vitamin B7)
-
Essential for keratin production.
-
TRINITY provides 300 mcg (600% NRV) — a significant, meaningful dose.
2. Iron
-
Carries oxygen to hair follicles.
-
Deficiency is strongly linked with hair thinning, especially in women.
-
TRINITY uses iron bisglycinate, a gentle, well-absorbed form.
3. Zinc
-
Regulates oil production in the scalp and supports protein synthesis.
-
Present in TRINITY’s Night Formula.
4. Vitamin C
-
Supports collagen production and boosts iron absorption.
-
Included in TRINITY’s Morning Formula.
5. Selenium
-
Protects against oxidative stress that can damage hair follicles.

✅ Timed formulas — nutrients delivered when the body best uses them (e.g. B-complex in the morning, magnesium at night)
-
✅ No fillers, binders, or sugars — unlike many “beauty” gummies
🧠 Summary
The best supplements for hair growth contain biotin, iron, zinc, vitamin C, and selenium — all of which play essential roles in follicle health, oxygen delivery, and keratin production.
TRINITY combines these nutrients in bioavailable, filler-free forms, making it a complete system to support strong, resilient hair.
❓ FAQs: Supplements for Hair Growth
Q: What is the best vitamin for hair growth?
A: Biotin is key, but hair also needs iron, zinc, and vitamin C for proper growth.
Q: Can iron deficiency cause hair loss?
A: Yes — low iron is one of the most common nutrient-related causes of thinning hair.
Q: Do biotin gummies really work?
A: Most contain very little biotin, plus added sugar. TRINITY provides 300 mcg (600% NRV) in a clean, capsule format.
Q: How long do hair supplements take to work?
A: Hair grows slowly, so noticeable results may take 3–6 months of consistent supplementation.
