It doesn’t matter what you are doing – browsing the Internet, surfing cable, or flipping through your favorite magazine – you will find plenty of advertisements that promote the magical qualities of weight loss supplements. Weight loss supplements come in all manner of shapes, sizes and styles and have a range of claims and solutions. And there are all manner of claims – from pills, patches and creams. But do these cures really work? Only you can decide that for yourself. Let’s take a look at some of the most popular weight loss products and the positive benefits and negative effects of each, so you can make up your own mind.
Bitter Orange, Citrus Aurantium, and Sour Orange: These products are made directly from concentrated extracts from orange peel. They often claim that they increase metabolism, but there has been no conclusive tests to back this up. Bitter Orange, Citrus Aurantium, and Sour Orange contain the stimulant synephrine, which can cause hypertension and cardiovascular toxicity. Individuals with heart disease, hypertension, and glaucoma should avoid these at all costs.
Chromium (Examples of Chromium products include Puritan’s Pride Chromium Picolinate, Vitamin World Naturally Inspired Yeast Free Chromium Picolinate, Nutrilite Trim Advantage): The claims that chromium increases weight loss and improves body composition have been backed by one main study which proved this to be the case. There are two types of chromium: Trivalent (which the body requires and is considered safe in doses of 200 micrograms or less daily) and Hexavalent (but this form can cause stomach upsets, ulcers, convulsions, kidney and liver diseases, and death).
Conjugated Linoleic Acid (CLA) (Examples of this product include Vitamin World CLA, Nature Made CLA, Now Foods CLA): This product claims to promote leanness, but there are very few studies that actually support the marketing claims. While more research is needed, CLA is generally safe.

Vitamins
Natural vitamins are those organic food substances which are found only in plants and animals, i.e., living things. The body is not able to synthesize or manufacture vitamins (although there are a few exceptions to this). Because of this, they must be supplied either directly in the diet, or by way of dietary supplements. Vitamins are vital if our body is to function normally. They are absolutely necessary for our growth, general-well being and vitality.
Vitamins cannot be assimilated without ingesting food. This is why it is suggested that vitamins must be taken with a meal. They help to regulate the body’s metabolism, assist in forming the bone and tissue, and help convert fat and carbohydrates. However, one must remember that vitamins cannot replace food.
We shall now look at the importance of each of the vitamins by turn.

Do you know where the idea of drinking eight glasses of water per day came from? Neither does anyone else.
Yet many nutritionists, weight-loss experts and general health gurus claim we must drink that much every day.
I certainly tried to do it. I would drink coffee in the morning, then maybe force down a glass of water. By the time I had sweet tea with lunch, I was not thirsty but would try to choke down two more glasses of water in the afternoon.
By the time I had a glass of wine and more tea for supper, I was full – and facing five more glasses of water! I just could not do it day in and day out.
I know many of you can, and I’m proud of you. But for the rest of us who wallow in guilt, there is good news.
Before I get to that, let me reinforce the necessity of good hydration. Drinking water in adequate amounts is necessary for maintaining the organ systems. In a resting state, this is easy and can be done in many ways. But in times of vigorous physical activity or in high temperatures, consumption must be increased and maintained to keep the body’s core temperature from rising dangerously and to prevent dehydration.

Hair growth patterns in humans depend upon the interaction of natural cycles of hair growth and hair loss. The hair growth cycles follow a structured process that has 3 phases. These 3 phases are – anagen (the growth phase), catagen (the transitional phase) and telogen (The resting Phase). The hair is actively growing only in the anagen phase where it increases in length by about 1 cm in every 28 days. Hair loss occurs when the hair is in the resting phase. Most hairs in the resting phase lie in the skin separated from the dermal papilla at its base. Since the hair is not held tightly at its root, it is prone to shedding at any point.
The entire hair growth cycle is under the influence of hormones and their metabolic products. Dihydrotestosterone is the most important metabolite that plays the major role in retarding the hair growth and affecting hair loss. Accumulation of DHT (dihydrotestosterone) within the hair follicle is considered to be the main cause of hair loss.
The DHT mediates the hair loss through its direct action on the androgenic receptors in human scalp tissue. It interrupts the normal physiologic environment and function of the hair follicles. Faster hair growth in both men and women is possible if action of DHT is blocked.
The organic extracts of some of the herbal formulations act at the level of the androgenic receptors of the scalp. These extracts contain substances which directly compete with DHT with its action. They act as a natural androgenic blocker by inhibiting the active binding of DHT to the hair follicle receptors. When this binding is inhibited the amount of follicle damage is automatically reverted and follicles respond by affecting quick hair growth.
