Greek yogurt has more than double the amount of protein as regular yogurt. One serving of Greek yogurt has 20 grams of protein, whereas a serving of low-fat yogurt has 9 g of protein.

Dermatologist Recommendations for Biotin
After all, many products advertise biotin as a hair growth booster. Even in cases where a biotin deficiency is present, biotin supplements may not necessarily prevent hair loss. Further, the study was small, and it’s possible that the participants were deficient in one or more nutrients present in the supplement that affect hair health. Any such deficiency could have been corrected through the study period, resulting in hair growth. In an older 2012 study, women with self-perceived thinning hair were randomized to receive either a multi-ingredient hair growth supplement that contained biotin or a placebo for 6 months (4). It may take several months (e.g., 90 days or more) to notice a change.

Like all B vitamins, biotin helps to metabolize carbohydrates, fats, and amino acids, which are the building blocks of protein. Well, we looked into it and found that while biotin isn’t a magical cure-all for hair growth, it could have some positive benefits. However, little is known about biotin’s role in hair health and whether this supplement can truly help. It’s important to understand what’s causing your hair loss, but this can take some detective work. Dr. Bergfeld says dermatologists start with a thorough physical exam. They consider not just your diet, but your exercise habits and family history as well.
What to look for in a hair growth serum
According to WebMD, biotin supplementation is safe for up to 6 continuous months. If you would like to take it longer than that, we recommend speaking to your doctor. If you’ve been taking the vitamin for several months (5 months or more) and haven’t seen any degree of improvement in your hair growth, it’s probably safe to say that the supplement is not going to work for you.
This article explores available research to tell you whether biotin can help men grow hair and if there are any risks of taking the supplement. If you have any unusual symptoms while taking a supplement, stop using it immediately and be sure to make an appointment with your doctor ASAP. Additionally, biotin has been shown to interfere with some lab results, so be sure to tell your physician you're taking the supplement before getting any bloodwork done. If you have certain dietary restrictions or need an extra biotin boost, certain supplements may be used as alternatives. Anything that disrupts your gastrointestinal (GI) tract can also affect hair growth, she adds.

However, there is limited evidence for this in scientific research and much of the existing evidence is old. More research is needed, but there is also some evidence that biotin may improve symptoms of peripheral neuropathy and help people with diabetes gain control of their blood sugar. While the use of biotin is generally safe, the vitamin may interfere with some lab tests and medications, so you should tell your healthcare provider if you plan to use it. Biotin (vitamin B7) is a micronutrient vital to energy production, nervous system health, and other bodily functions.
“Biotin is found in Brewer’s yeast, egg yolk, whole wheat bread, avocado, salmon, cheese, bananas, and nuts,” she says. “Most people who eat a normal diet don’t suffer from biotin deficiency unless it’s genetic.” In addition to your diet, you can also use haircare that has biotin right in it for stronger strands. While biotin has been popular for quite some time now, it’s simply not the hair-loss cure-all that so many supplement companies make it out to be. Take it from board-certified cosmetic dermatologist Robert Finney, MD, who sees patients struggling with hair loss every single day. "If biotin is truly deficient, then it would affect all hair on the scalp, not just the hairline or part,” he adds.
But for optimal hair benefits, consider a supplement with complementary nutrients. One hair-healthy ingredient to look for is vitamin D3, a fat-soluble vitamin that's required for healthy hair follicle function. Of vitamin D from their daily diet, and clinical vitamin D insufficiency persists in almost half of the population (41%14, to be exact). Taking a supplement can help you obtain adequate levels, as there are only a few foods that naturally offer vitamin D. Though exact figures aren't available, the National Institutes of Health reports that biotin deficiency is rare in healthy adults who are eating a balanced diet. There is no firm scientific evidence to support the use of biotin supplements to improve hair growth unless a person has a specific biotin deficiency.
For example, researchers in one study prescribed a biotin supplement to 22 patients with low biotin levels for hair loss following gastric sleeve surgery (6). In one study, a biotin deficiency was found in 38% of women complaining of hair loss. Of these participants, 11% had a history of deficiency risk factors, such as inflammatory bowel disease (IBD) or the use of certain medications like antibiotics (5). Although the evidence to support biotin alone for hair growth is weak and limited, the evidence is slightly stronger for preventing hair loss. Whether you’ve just started using biotin supplements or are considering increased biotin intake, we’ll bet you’ve got a lot of questions. One of the most common questions people ask about it is, “How long does biotin take to work?
