Vegans more likely to have <10 ng of Vitamin D - Spain Feb 2024

Sustainable healthy diets are promoted, and consequently vegetarian diets are currently increasing. However, scientific information on their effects on bone health is scarce. A cross-sectional study was performed in adults (66% women) classified into three groups: omnivores (n = 93), lacto-ovo vegetarians (n = 96), and vegans (n = 112). Nutrient intake, body composition, physical activity, vitamin D status (25-hydroxycholecalciferol, 25-OHD), parathormone (PTH), and bone formation (bone alkaline phosphatase, BAP) and resorption (N-telopeptides of type I collagen, NTx) markers were determined. Lacto-ovo vegetarians and especially vegans showed lower protein, fat, calcium, phosphorous, vitamin D, retinol, iodine, and zinc intakes, and higher carbohydrate, fibre, carotenes, magnesium, and vitamin K intakes compared to omnivores. Body composition was similar in the three groups that performed vigorous physical activity regularly. Body bone mass and muscle mass were positively correlated with BAP, and time performing physical activity with 25-OHD. The prevalence of vitamin D deficiency or insufficiency (25-OHD < 75 nmol/L) was 93.7% in the studied population, and vitamin D deficiency (25-OHD < 25 nmol/L) was significantly higher in vegans. Vegetarians of both groups had increased PTH and NTx with vegans showing significantly higher PTH and NTx than omnivores. Conclusion: Adult vegetarians, especially vegans, should reduce the risk of bone loss by appropriate diet planning and vitamin D supplementation.

Vegan infants often need more Vitamin B12, Vitamin D, Iodine, Selenium - Dec 2024

Toward Supplementation Guidelines for Vegan Complementary Feeding
Food Sci Nutr. 2024 Nov 1;12(12):10962-10971. FREE PDF
Christian Koeder 1

Previously published recommendations for vegetarian (including vegan) diets for children have highlighted the need for vitamin B12 supplementation. Increased attention to several other key nutrients (including iodine, vitamin D, calcium, and iron) has also been recommended. However, an overview focusing on supplementation guidelines, specifically for vegan infants, has not been published, and a potential requirement for iodine and/or selenium supplementation in (some) vegan infants has not been discussed. Vegan complementary feeding should be supplemented (particularly with 5 μg/day of vitamin B12 and 10 μg/day of vitamin D). Iodine should be supplemented (up to 110 μg/day) if the intake of breast milk and infant formula is low, and selenium supplementation (5 μg/day) should be considered in regions with low soil selenium levels. Caution is required to avoid excessive intakes of iodine and particularly selenium. Supplements for vegan infants are on the market, and observational studies are urgently needed to assess the nutrient intake (including supplements) and status in vegan infants.

Vegan form of Vitamin D3 - made from Lichen

Vitashine
They developed a process to make a Vitamin D3 spray from Lichen and coconut oil
Can be sprayed into the mouth or onto food (vegetables of course)
The vitamin D3 spray they sell it is somewhat expensive
1 spray = 200 IU, 150 sprays per bottle or 30,000 IU per bottle
3 bottles in US$ for $38.85 which includes delivery
The cost is $0.43 per 1000 IU
The lowest cost by non vegan suppliers is less than 1 cent per 1,000 IU
So, their Lichen spray is about 43X more expensive than the capsule form from sheep (it apparently costs the company 1000X as much the Vegan form)
As of October 2011 they appear to be the only registered supplier of Vegan D3, but I anticipate competition

Q /A with the company Nov 1, 2011

1. Where do your lichen live - in the ocean?, in an aquarium?, ....
   No, they live on land and grow wildly in many areas.
   We obtain our strain from various mountainous regions in Asia and USA (designated areas, not taking from open land – i.e. not taking food from wildlife for instance).
   We can’t divulge the exact strain, again for confidentiality reasons.
2. Are the lichen totally under the water, totally in the air, or some mix?
   Totally in the air.
3. Do you add extra UV (pot growers and many others have found the UV helps a lot)
   This is the important bit.
   Altitude is absolutely key to ensure the right balance between UV exposure and surviving the elements (temperature, nutrients etc.).
4. How long do the lichen take to grow to be harvestable? days, months, years,
   Lichens take a long time to grow, and of course with possible seasonal variations with temperature and UV levels, we work with multiple growing sites.
   This allows us to not only ensure we achieve a good yield based on the season but also cope with the slow growing rate.
5. What % by weight is the vitamin D3 (and, if you should happen to have it, what the % is for D3 from wool)
   It takes around 500kg of dry lichen material to obtain 1kg of our extracted Vitamin D3 rich oil.
   The level of D3 in that oil varies from batch to batch so we of course dose Vitashine accordingly.
   The process for wool D3 is very different and they simply sell high D3 quantity materials, standardised to specified levels.

There is quite a lot of information here: http://vitashine-d3.com/vitashine.html

Be careful to avoid multivitamins which contain Vitamin D2

These are mainly vegan vitamin D - it was not until mid 2011 that a vegan D3 became available from two suppliers (and much more expensive)
It appears that vitamin D2 sometimes actually DECREASES vitamin D3 in the body
