Combined A/D3/K2 supplement delivers high potency at unbeatable value.

High-potency A+D3+K2 combo offers double-strength nutrients per capsule, outperforming individual supplements at $0.11/dose.

This review is from Amazon.com for product:

Vitamatic ADK Vitamin Supplement, 180 Veg Capsules, High Potency Vitamins A, D3, K2 for Bone Health, Calcium Absorption, Non-GMO, Gluten Free

And so I was really happy to have this product that combines A, D3 and K2. Just one capsule in the morning and I'm done.

Yes, I realize that sometimes we only need to beef up an individual vitamin and we don't want to increase all 3 of them. For that, I have separate A, D3 and K2 products. Now truth be told, (i) this product has over twice the D3 of my other [specialized] D3 supplement, and (ii) it has almost twice the K2 of my other [specialized] K2 supplement.

And at $19.99 for 180 doses (at the time of this review), yes, this is a great product.

Vitamin Basics & Tips

Vitamin A plays crucial roles in vision, immune function, and cellular communication. When combined with D3 and K2 as in this supplement, they create synergistic effects: D3 enhances calcium absorption, while K2 directs calcium to bones and teeth rather than arteries. The fat-soluble nature of these vitamins means they're best taken with meals containing healthy fats for optimal absorption.

While this product combines all three nutrients, individual needs vary. Vitamin A requirements differ based on age (700-900 mcg RDA for adults) and pregnancy status. Excessive preformed vitamin A (retinol) can cause toxicity, unlike plant-based provitamin A (beta-carotene). The combination formula simplifies supplementation but requires monitoring total nutrient intake from all sources to avoid exceeding upper limits (3,000 mcg daily for vitamin A).

Modern diets often lack sufficient K2 (found in natto and fermented foods) and D3 (from sunlight exposure), making combined supplements practical. However, those with specific deficiencies or medical conditions should consult healthcare providers, as high-dose combinations may not suit all users. Proper storage in cool, dry places preserves capsule efficacy over the 180-dose supply period.
