Strong bones and body

It’s estimated that up to 40% of American adults are insufficient, and 6% are full-on deficient in vitamin D. Vitamin D deficiency can lead to tiredness, back pain, and brittle bones. Contrary to popular belief, getting a few minutes in the sun every day is unlikely to sustain optimal levels, especially as you get older and your skin becomes less efficient at converting sunlight. Same goes for eating vitamin D-rich foods like egg yolks (you'd need 16 eggs a day to hit the recommended dosage). Standard vitamin D supplements will take 8-12 weeks to begin improving your levels. That's potentially an extra three months of living below your best. We created Lifeforce Vitamin D+K using a highly bioavailable form of vitamin D formulated to get your levels optimized faster.
