Beyond Glucosamine & Chondroitin: Supplements for Arthritis
When you think of dietary supplements for the joints and
arthritis, chances are that you're thinking of glucosamine and chondroitin
sulfate--which makes sense since there is good research to support the use of
these nutraceuticals for this purpose.
What many people don't know, however, is that there are other
nutraceuticals which also can be used effectively for arthritis. Three of these are hyaluronic acid, calcium
fructoborate and bromelain.
Hyaluronic acid
Hyaluronic acid (HA) is a naturally occuring substance found
outside of cells, in the tissues and body fluids of all vertebrates. HA is a
polysaccharide (long-chain sugar) chain found most primarily in cartilage,
synovial fluid, skin, and the aqueous humor in the eye [1]--areas in the body
where it serves as part of the supporting structure, cushioning and
lubricating.
Research suggests that hyaluronic acid may prevent the
breakdown of natural cushioning barriers in joint [2]. It seems that hyaluronic
acid binds to cellular receptors on the surface membrane of cartilage and other
cell types, supporting wound healing as well as reducing the enzymes that
contribute to cartilage breakdown [3-4]. In randomized double-blind
placebo-controlled study, 20 subjects with arthritis of the knee received
either an oral form of hyaluronic acid or placebo for 8 weeks. The results were
that daily supplementation with hyaluronic acid was useful to enhance several
markers of quality of life in adults with knee arthritis, including improving pain
and discomfort [5].
One form of hyaluronic acid that is significantly more
effective than other forms is Hyal-Joint.
Hyal-Joint is 2 to 4 times more active in nourishing synovial fluid and
supporting its health than regular hyaluronic acid. The increased activity
comes from the unique (patent pending) composition of Hyal-Joint which
naturally contains hyaluronic acid, as well as collagen and other proteoglycan
which together create a special synergistic effect [6].
Fruitex-B® (aka, Calcium
Fructoborate)
Fruitex-B®, which is also known as calcium fructoborate, is
a form of the mineral boron. In research involving subjects with arthritis, 50%
of the patients who received a daily supplement of 6 mg of boron noted
improvements in joint pain associated with movement, while only 10% of subjects
given a placebo experienced similar improvement [7]. Clinical studies
demonstrate that Fruitex-B® especially effective in reducing pain in patients
with arthritis [8]. The reason for the improvements in pain may be the result
of boron helping to reduce joint inflammation [9-11].
Bromelain
Bromelain is a proteolytic (i.e., protein-digesting) enzyme
found in pineapples. Bromelain has
proteolytic action on a variety of proteins, breaking them down into smaller
peptides and amino acids [12]. Beyond
its protein digesting capacity, research has shown that bromelain helps reduce
inflammation. This was seen in a study where bromelain helped patients with arthritis,
73% of whom had good to excellent results [13].
