Review: A Great Boost to My Daily Wellness Routine - These silica capsules have been a fantastic addition to my daily vitamin lineup. I started taking them for the known health benefits—especially for supporting healthy hair, skin, nails, and even bone and joint health—and I've definitely noticed a difference. My nails feel stronger, my hair looks shinier, and overall I feel good knowing I'm giving my body the support it needs from the inside out. They're easy to take, gentle on the stomach, and fit right into my existing supplement routine without any issues. If you’re looking for a simple way to support your body’s natural strength and beauty, I highly recommend adding these to your regimen!
Review: Here is some data from a study regarding nutritional benefits ... - Here is some data from a study regarding nutritional benefits of Silica. The reference citation is at the bottom of the article and this is not the article in its entirety. Health implications There a number of studies with compelling results suggesting the essentiality of silicon, delivered as silica, for humans. Indeed, there is continuing debate as to whether there should be an RDI. Silica is omnipresent in US drinking water and is found in surface and well water in the range of 1 - 100 mg/L. However, silica is not listed in the Primary or the secondary Drinking Water Standards issued by the US EPA. The history of consumption coupled with the lack of anecdotal toxicity of aqueous silica has resulted in relatively little attention to the essentiality of silica-derived silicon. A functional role for silicon has yet to be identified but clearly it is feasible and likely. Silicon is known to be required by chicks and rats for growth and skeletal development. For example, inducing silicon deficiency produces profound results including deformities in skull and peripheral bones, poorly formed joints, reduced mineral contents of cartilage, collagen, and disruption of mineral balance in the femur and vertebrae. The obvious effect of silicon deficiency on bone supports the notion that it is critical for bone formation as shown in studies with chickens and rats (15-18). Chicks fed silicon-deficient diets also showed structural abnormalities in the skull and long bones such as the femur (12). More in depth studies using rats deprived of silicon showed decreased bone hydroxyproline levels and inhibited alkaline and acid phosphatases (19). Regarding the former, silicon has been shown to contribute to prolylhydrolase activity necessary for normal collagen formation (12). Silica enhances and maintains articular cartilage and connective tissue due to interaction of silicon with glycosaminoglycan formation, a structural building block of these tissues. Silicon is also a constituent of enzyme(s) involved in bone matrix formation suggesting a role in bone calcification. Clearly, silicon is localized in sites of active bone growth supporting a role for dietary silica. Silicon has also been suggested to exert a protective role in atherosclerosis, in part, due to maintenance of blood vessels (20). For example, increased silica consumption reduces the incidence and severity of atherosclerosis presumably through its effects on blood vessel-associated glycosaminoglycan and collagen integrity and function. Silica is also thought to be beneficial in Alzheimer's disease because silicon can interact with aluminum and prevent aluminum toxicity often associated with Alzhemier's disease (21). This protective effect has also been noted in humans where dietary silicon protected against aluminum accumulation and presumably neurodegenerative effects (22). Collectively, evidence supports a protective role for silicon in maintaining bone health, cartilage and connective tissue structure, prevention of toxicity to the brain, and maintenance of blood vessel integrity. Summary and contusions Many forms of silica exist with potentially beneficial and detrimental effects. For example, inhaled paniculate silica can be toxic and depends heavily on route of exposure and chemical form. Silica can also dissolve in water to form nontoxic bioavailable silicic acids. This form of absorbable silica found in foods and water, and especially bottled waters, is readily absorbed, reaches key tissue and organ target sites of action, and is efficiently excreted. Indeed, there are compelling data to suggest myriad beneficial effects from silica in water on human health. However, the lack of apparent toxicity and the ongoing debate regarding essentiality have obscured the relative importance of different chemical forms and potential contributions of silica. Further research on silicon is critically needed particularly focusing on the physiological roles of silicon and how this relates to human health, as well as the dependence on chemical speciation. Specifically, ample data exist to support a possible role of silicon in atherosclerosis and hypertension, several bone disorders, Alzheimer's disease, and other conditions know to occur particularly in the elderly. Perhaps the focus of future research should begin with this target population of susceptible individuals. Martin, K.R. The chemistry of silica and its potential health benefits.

## Questions & Answers

**Q: What type of calcium is used ?**
A: Hi...  First, Solgar's Oceanic Silica (from Red Algae) only has 200 mg of calcium, which is only 15% of the RDA. The bottle does not state what type or source of that calcium, but does state on the front of the bottle 'Dairy Free'.  You could get in touch with Solgar, Inc. 500 Willow Tree Rd., Leonia, NJ 07605   or phone 877-SOL-GAR4  (877-765-4274).   Hope this helps you...

**Q: does this cause acne or oily skin?**
A: Hi Kekoa,  this product contains silica & a small amount of calcium (from red algae), which are minerals, not an oil at all.  If you are unsure, maybe check with your Doctor.

**Q: Silica on the market is over, when will there be more? It's missing from all the sites I searched.**
A: Derived from oceanic red algae rather than horsetail, which is the silica source for all of the other brands I have used in the past. It is not advised to take horsetail long term because it contains thiaminase, which breaks down the vitamin thiamine (B1). A B1 deficiency has a negative impact on the heart, brain and nervous system.
—Solgar has been around a long time, and it has a good reputation. It is located in New Jersey, and the company states that their product ingredients are sourced from the US and that their supplements are manufactured here.
—Vegan friendly, using cellulose capsules rather than gelatin.

I personally take silica as one of multiple supplements (calcium, magnesium, MK-7, D3, strontium, and boron) which synergistically promote bone health, but silica has many other benefits as well as that, including the following:

—It promotes healthy hair, nails and skin.
—It promotes healthy teeth.
—It promotes healthy tendons and ligaments.
—It enhances the immune system.
—It supports pancreatic function.
—It helps prevent cardiovascular disease by strengthening blood vessels and lowering high blood pressure.
—It protects lung tissue.
—It helps decrease swelling (edema) in the body.
—It helps prevent kidney stones, heal infections in the urinary tract, and it is a natural diuretic.
—It helps prevent or heal intestinal inflammation and prevent both diarrhea and constipation.
—It helps heal hemorrhoids.
—It helps heal infections of all types.
—It helps with osteoarthritis and rheumatism.
—It helps to strengthen nerve cells and connective tissue in the brain and spinal cord, which helps to prevent memory loss due to age and Alzheimer’s.
IS HELPING ME WITH MY SKIN AND MY HAIR

**Q: If this is made from red algae, does it contain iodine? Iodine should be avoided if you have certain thyroid conditions.**
A: Our Oceanic Silica provides 108mg of Silica from Red Algae.

While this formula does not have added Iodine, we do not test the finished product for any naturally occurring Iodine, and therefore we cannot give you an exact amount or confirm its presence.

Apologies,
