- 0:00vitamin C supplements and skin serums
- 0:02are an utter waste of your hard-earned
- 0:04money and there are far better options
- 0:05to improve your health which we'll go
- 0:07through later in the video excitement
- 0:09about vitamin C kicked into overdrive in
- 0:11the 1970s where Linus Pauling suggested
- 0:14that vitamin C could successfully treat
- 0:16and prevent the common cold this is
- 0:18because in addition to its antioxidant
- 0:20properties vitamin C plays a critical
- 0:22role in immune function it's also
- 0:24required to build collagen
- 0:26neurotransmitters and is heavily
- 0:27involved in protein metabolism
- 0:29disappointingly though the results from
- 0:31clinical studies have been inconsistent
- 0:33and a massive Cochrane review was done
- 0:35which is at the very top of the evidence
- 0:36pyramid and it concluded that vitamin C
- 0:39did not reduce the chances of developing
- 0:41the common cold and therefore routine
- 0:43vitamin C supplementation is not
- 0:45justified because of its antioxidant
- 0:48properties vitamin C was hoped to reduce
- 0:50the chance of heart attacks multiple
- 0:52large-scale Studies have been done and
- 0:54before I get into the results of those
- 0:55trials I want to explain the rationale
- 0:57for using 500 milligram dosages the
- 1:00recommended daily intake is 90
- 1:02milligrams for males and 75 milligrams
- 1:04for females to put that into context
- 1:07five servings of fruit and vegetables
- 1:09can provide more than 200 milligrams of
- 1:11Vitamin C but here's the crucial point
- 1:13from intakes of 100 milligrams and above
- 1:16our cells are fully saturated they've
- 1:18got all of the vitamin C that they could
- 1:20possibly want and above that dose
- 1:22vitamin C is only slightly increased in
- 1:24the blood the rest is peed out there are
- 1:27liposomal versions of vitamin C which
- 1:29are more bioavailable compared to the
- 1:31regular versions however liposomal
- 1:33vitamin C is not expected to offer any
- 1:36further benefits because again our cells
- 1:38at 100 milligram dosages and above have
- 1:40got all of the vitamin C that they could
- 1:42possibly want and they get rid of the
- 1:44rest the trials used 500 milligram doses
- 1:46because at that dose you're accounting
- 1:48for any potential absorption issues that
- 1:50some patients may have the first study
- 1:53involved over 8 000 women who were
- 1:55followed up for an average of over nine
- 1:57years unfortunately vitamin C had no
- 1:59effect on any of the cardiovascular
- 2:01outcomes the same result was found in a
- 2:03massive French study involving over 13
- 2:06000 people in a randomized double-blind
- 2:08placebo-controlled trial participants
- 2:10were followed up for seven and a half
- 2:12years and there were no differences in
- 2:14cardiovascular disease or all cause
- 2:16death threats furthermore a Cochrane
- 2:18review combined all of the relevant
- 2:20studies together and they concluded that
- 2:22currently there is no evidence to
- 2:23suggest that vitamin C supplements
- 2:25reduce the risk of cardiovascular
- 2:27disease there are far better options to
- 2:29reduce your chance of heart attacks
- 2:30which we'll go through at the end of the
- 2:32video moving on to cancer a randomized
- 2:34placebo-controlled study involving over
- 2:3614 000 participants who were followed up
- 2:39for 10 years found no effect for vitamin
- 2:41C supplements on reducing cancer rates
- 2:43the same results were found in the
- 2:45women's study where again we could see
- 2:47no effect on cancer rates one
- 2:49interesting area of research however is
- 2:51intravenous vitamin C because if you
- 2:53inject vitamin C directly into patients
- 2:56you achieve significantly larger vitamin
- 2:58C levels and concentrate situations of
- 3:00that magnitude they are selectively
- 3:02toxic to cancer cells in the lab however
- 3:05we don't have any large
- 3:06placebo-controlled studies so it's
- 3:08premature to determine what role IV
- 3:11vitamin C may play in the treatment of
- 3:13cancer but I do look forward to
- 3:14reporting on future studies in that area
- 3:16of research the caveat however is that
- 3:18in certain circumstances IV vitamin C is
- 3:21toxic a study published in the New
- 3:23England Journal of Medicine last year
- 3:25for intensive care patients found that
- 3:27those patients who received intravenous
- 3:29vitamin C had a higher risk of death or
- 3:32persistent organ dysfunction which is
- 3:34why this therapy needs careful research
- 3:36it should not be recommended until we
- 3:38have those studies the next reported
- 3:40benefit is skin Health but our skin
- 3:42cells can get all of the vitamin C that
- 3:44they could possibly want from a great
- 3:45diet alone there are many vitamin C skin
- 3:48serums which claim to have benefits for
- 3:50skin Health however almost all of these
- 3:52claims have no scientific testing to
- 3:54back them up plus a correctly formulated
- 3:56vitamin C skin serum is incredibly
- 3:58costly because regular vitamin C it's
- 4:01unstable when exposed to oxygen making
- 4:03it useless there are far better options
- 4:05for skin Health at the end of the video
- 4:07so what about the risks of vitamin C
- 4:09supplements well generally it has low
- 4:11toxicity and it's not believed to cause
- 4:13serious adverse health risks at high
- 4:16intakes the most common side effects
- 4:18include things like diarrhea or gastro
- 4:20discomfort there's also the potential of
- 4:22causing kidney stones so people with a
- 4:23history of kidney stones they need to
- 4:25tread carefully with taking vitamin C
- 4:27supplements but instead of wasting your
- 4:29money on vitamin C supplements get your
- 4:31vitamin C from a great diet filled with
- 4:34fruit and vegetables and thankfully the
- 4:36war against fruit from the keto diet
- 4:38gurus is coming to an end make sure to
- 4:40regularly exercise prioritize sleep and
- 4:43if you do want to take supplements to
- 4:44improve skin Health consider things like
- 4:46collagen peptides and hyaluronic acid
- 4:48and I've got a video about the
- 4:50hyaluronic acid research here a massive
