This review is from Amazon.com for product:

Smart for Life ADK Vitamins Supplement - High Potency Vitamin ADK - Vitamin D3, Vitamin K2 & Vitamin A - Supports Bone and Heart Health - 5,000 IU Vitamin A - 5,000 IU Vitamin D3-500mcg Vitamin K2

I think this is an excellent A, D3, K2 supplement. Each purple colored capsule delivers 5,000 IU of A and D3, and 500 mcg of K2. All of these vitamins work in tandem to promote bone health and to help prevent Osteoporosis as we age. There are 90 capsule per bag which is a 3 month supply.

Vitamin Basics & Tips

Vitamin A, D3, and K2 play critical roles in maintaining bone health and preventing age-related conditions like osteoporosis. Vitamin A supports vision and immune function, but its active form (retinol) also aids in bone remodeling. However, balance is key—excessive Vitamin A intake may paradoxically weaken bones. Vitamin D3 enhances calcium absorption in the gut, ensuring adequate mineral availability for skeletal strength. Meanwhile, Vitamin K2 directs calcium into bones and teeth while preventing harmful arterial calcification. This trio works synergistically: D3 increases calcium uptake, K2 ensures its proper distribution, and A supports cellular processes in bone tissue.

For optimal bone health, adults should aim for 700–900 mcg of Vitamin A daily (from foods like sweet potatoes, spinach, or supplements), 600–800 IU of D3 (sunlight exposure or fortified foods), and 90–120 mcg of K2 (found in fermented foods like natto). Supplements combining these vitamins simplify dosage accuracy, especially for aging individuals at risk of osteoporosis. Always consult a healthcare provider to avoid overdosing, as fat-soluble vitamins (A, D3, K2) can accumulate in the body.
