About Anabolic Laboratories - Ultra K2-D3

Ultra K2-D3 from Anabolic Laboratories combines vitamin K2 (as menaquinone) with vitamin D3 (cholecalciferol) in a convenient chewable tablet format, supporting calcium metabolism, bone mineral density maintenance, and cardiovascular health. Designed for adults seeking a synergistic K2/D3 pairing in a format that bypasses the need for swallowing capsules.

Why It's Worth Considering: Pairing K2 with D3 addresses the complementary roles both nutrients play in directing calcium to bones rather than soft tissues — a formulation logic increasingly recognized in clinical nutrition practice.

Who Benefits

Best For

  • Adults seeking combined vitamin K2 and D3 in chewable tablet form
  • Those supporting calcium metabolism with MK-7 K2 and cholecalciferol D3
  • Individuals who prefer chewable delivery over traditional vitamin K2-D3 capsules
  • Older adults maintaining bone density with daily vitamin K2 and D3 intake

Cautions

  • Known allergy to any ingredient (check label)
  • Currently pregnant or breastfeeding (consult healthcare provider)
  • Taking prescription medications (check for interactions)
  • Under 18 years of age (unless recommended by pediatrician)

Frequently Asked Questions

  • Store in a cool, dry place away from direct sunlight. Most supplements are stable at room temperature (59-77°F). Keep the bottle sealed between uses. Check the label for any specific storage requirements — some probiotics and oils require refrigeration.

  • Most supplements can be taken together safely. However, some minerals compete for absorption (zinc and iron, calcium and magnesium) and should be taken at different times of day. If you're taking prescription medications, consult your healthcare provider about potential interactions.

  • Most supplements benefit from consistent daily use over 2-3 months to achieve full effect. Some (like vitamins and minerals) can be taken indefinitely as part of a daily routine. Others (like specific herbs) may benefit from cycling. Follow the product's recommended protocol or consult a practitioner.

  • Fat-soluble supplements (vitamins A, D, E, K, omega-3, CoQ10) should be taken with a meal containing fat. Water-soluble supplements (B vitamins, vitamin C) can be taken anytime. Minerals are generally best absorbed with food. Probiotics should be taken with or just before a meal. Check the product label for specific timing recommendations.

  • Track your specific health goals — energy levels, sleep quality, joint comfort, digestion, mood, etc. Most supplements take 2-8 weeks for noticeable effects. For objective measurement, baseline lab tests before starting (and repeat at 3 months) provide definitive evidence. The Gabriel Score incorporates clinical evidence for expected outcomes.
