HKVitals Complete Product Guide — Every Product Explained 2026

HKVitals has grown from a basic supplement brand into HealthKart's most comprehensive everyday wellness range. Here is the complete, evidence-based guide to every major HKVitals product category:

💊 Biotin — HKVitals' Flagship Product

HKVitals Biotin is the brand's highest-selling product — and the most confusing category because of dosage options (5,000 mcg and 10,000 mcg) and format options (tablets and gummies).

HKVitals Biotin 5,000 mcg vs 10,000 mcg — The Complete Answer

• 5,000 mcg (standard dose): The clinical reference dose for hair, nail, and skin support. Sufficient for the vast majority of adults with normal Biotin status. Evidence: Multiple randomised controlled trials show 5,000 mcg supplementation significantly improves nail thickness and reduces nail brittleness in women with brittle nails within 6 months.
• 10,000 mcg (high dose): For documented Biotin deficiency (rare — symptoms include hair thinning, skin rash, neurological changes) or users who've completed 3+ months at 5,000 mcg without measurable improvement. No safety concern — Biotin is water-soluble with no established upper tolerable intake limit in any country's dietary guidelines.
• Gummies vs tablets: Gummies absorb slightly faster (pre-dissolved in gelatin matrix); tablets have longer shelf life and are suitable for vegans (check the specific SKU — HKVitals offers both veg and non-veg gummy variants). For daily compliance: gummies have higher adherence in most user surveys because of palatability.
• Important lab note: Biotin supplementation at 5,000+ mcg interferes with certain thyroid hormone tests (T3, T4, TSH) and cardiac troponin tests, causing false results. If you need these blood tests, stop Biotin supplementation for 48 hours before the test and inform your doctor you're supplementing.

☀️ HKVitals Vitamin D3 + K2 — Why the Combination Matters

Vitamin D deficiency is one of India's most prevalent nutritional problems — studies show 65–90% of Indian adults are deficient or insufficient. HKVitals Vitamin D3 + K2 (MK-7 form) addresses this with the evidence-backed combination:

• Vitamin D3 (2,000 IU): The active form of Vitamin D that increases intestinal calcium absorption by 30–40%. D3 is significantly more effective than D2 (ergocalciferol) for raising and maintaining serum 25-OH-D levels.
• Vitamin K2 (as MK-7, 45 mcg): MK-7 is the long-acting form of K2 (half-life of 72 hours vs MK-4's 4 hours). K2 activates osteocalcin (directs calcium into bones) and Matrix Gla Protein (prevents calcium depositing in arteries). Without K2, increased calcium absorption from D3 can increase arterial calcification risk in susceptible individuals.
• Why most Indian D3 supplements don't include K2: Cost — MK-7 is expensive. HKVitals' D3+K2 combination at accessible pricing is one of the best-value bone health supplements available in India.
• Who needs this: Anyone with documented Vitamin D deficiency, limited sun exposure (office workers in Indian metros), vegetarian diet (limited K2 food sources), post-menopausal women (bone density protection), or anyone above age 40.

🐟 HKVitals Fish Oil Omega-3 — Dosage and Forms

• Standard Fish Oil (1,000 mg, 300 mg EPA+DHA): Entry-level omega-3. The 300 mg EPA+DHA per 1,000 mg capsule is the standard concentration for general cardiovascular and joint health maintenance.
• Triple Strength Fish Oil (1,000 mg, 900 mg EPA+DHA): HKVitals' premium omega-3 — 3x the active EPA+DHA per capsule. Best for: users who want clinical-grade omega-3 benefits (reducing triglycerides, anti-inflammatory effects) in one daily capsule rather than three standard capsules.
• EPA vs DHA — what they do: EPA (eicosapentaenoic acid) is primarily anti-inflammatory — reduces CRP levels and prostaglandin E2 (linked to pain and inflammation). DHA (docosahexaenoic acid) is primarily neurological — the dominant omega-3 in brain tissue, critical for cognitive function and eye health. Both are needed; the ratio in most fish oil supplements is approximately 3:2 EPA:DHA.

✨ HKVitals Marine Collagen Peptides

• What it is: Type I and III collagen peptides from marine (fish) sources — the same collagen types found in skin, tendons, and blood vessels. Hydrolysed form (small peptide chains) has significantly higher bioavailability than native collagen.
• Evidence base: A 2019 systematic review in Nutrients (n=805) found hydrolysed collagen supplementation significantly improved skin elasticity, hydration, and collagen density vs placebo after 8+ weeks of daily use. The effective dose in most studies: 2.5–10g hydrolysed collagen peptides per day.
• HKVitals Marine Collagen vs bovine collagen: Marine collagen has smaller peptide size (lower molecular weight) → better absorption. Suitable for non-vegetarians and those avoiding beef products.

HKVitals vs TrueBasics vs MuscleBlaze Essentials — HealthKart Brand Comparison

Decision rule: If you're buying supplements purely for general health, hair, skin, immunity, or bone support without any sports performance goal — HKVitals gives the best quality at the most accessible price on HealthKart. If you need Informed Sport certification for competitive sport — TrueBasics. If you want gym-adjacent supplements alongside protein — MuscleBlaze Essentials.
