What is vitamin B10?
Vitamin B10 (or vitamin Bx) is an alternative name for the organic compound PABA, It's considered part of the Vitamin B complex , although it's not a vitamin nor an essential nutrient. It's found in brewer's yeast, organ meat, mushrooms, whole grains, and spinach.
PABA can absorb UVB rays and was once added to sunscreens. Some studies suggest that when taken orally, PABA can help with skin issues and darken gray hair, but research is limited.
Benefits:
Sun protection
PABA can absorb ultraviolet (UV) rays - especially UVB Rays, which are associated with sunburns and DNA damage. It was thus a key ingredient in sunscreen starting in the 1940s but later linked to allergic skin reactions in some people
Since 2019, PABA is no longer generally recognized as safe and effective for use in sunscreen by the Food and Drug Administration (FDA)
It's sometimes found in certain lotions and other products marketed as moisturizers, often in combination with aloe vera, and it's rarely used in shampoos, conditioners, and lipsticks
Skin-related disorders
Besides protecting against UV rays, PABA is claimed to help with skin issues related to hardening, tissue buildup, and discoloration - although how the compound may improve these conditions remains unclear
For one, PABA has been investigated for its use in the treatment of Peyronie's disease, which is characterized by the buildup of fibrous plaque inside the penis
One study found that taking a potassium PABA supplement significantly decreased plaque size in individuals with Peyronie's disease over 12 months, compared with a placebo
That said, more research is needed, and PABA is currently thought to be ineffective for treating this condition
PABA has also been identified as a possible treatment for scleroderma,an autoimmune disease that causes hardening of the skin and fibrous deposits in the organs
One retrospective study in 467 people with scleroderma found that 90% of those who received potassium PABA supplements experienced mild, moderate, or marked skin-softening, compared with 20% of a control group
Even so, this is one of the only studies on the topic, and it was conducted over 30 years ago. Other research has suggested that PABA has no effect on skin hardening associated with scleroderma, so additional research is needed .
Finally, PABA is often touted as a treatment for vitiligo, a condition marked by depigmentation and white patches on the skin. While some people with this disorder claim that PABA supplements help, limited scientific studies support the claim.
Hair care
One of the earliest uses of PABA supplements was to help with the repigmentation of prematurely Gray Hair . It's still used for this purpose today, and many personal testimonies suggest it's effective despite a lack of research.
Studies in the 1940s and '50s found that taking PABA at daily doses ranging from 200 mg to 24 grams led to hair darkening and helped gray hair return to its original color.
It's important to note, though, that some research found that hair became gray again after participants discontinued the supplement .
What's more, even though PABA was shown to darken gray hair in early studies, this effect has not been studied recently. Some researchers concluded that PABA should not be taken for the sole purpose of darkening hair, due to its unknown side effects.
